Then determine whether you are seeing a frame-rate drop, a freeze, a crash, or an input-detection problem. Boltgun Boom is Nitro Games Oyj’s mobile adaptation released on September 23, 2026, not the earlier PC and console game Warhammer 40,000: Boltgun. The available official material does not publish device requirements, frame-rate benchmarks, a supported-controller list, or a setting guaranteed to cure stutter. The steps below are safe diagnostic checks rather than verified universal fixes.
Confirm which Boltgun you have
Boltgun Boom is the mobile app listed by Nitro Games for Android and iOS. The Google Play listing describes a try-before-you-buy structure: the first three levels can be played before a one-time purchase unlocks the full game. Nitro Games announced the mobile release on September 23, 2026.

The separate game Warhammer 40,000: Boltgun has PC and console editions. Instructions involving Steam, Windows file verification, administrator launch options, or Steam Input apply to that other product, not to Boltgun Boom on a phone or tablet.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The Google Play listing showed an update dated September 24, 2026, with the note “Minor bug fixes and stability improvements.” That wording confirms that an update was published, but it does not identify an FPS fix, a controller fix, or a particular crash fix.

Identify the symptom before changing anything
Different symptoms point to different tests. Write down what actually happens instead of treating every interruption as “low FPS.”
| What you observe | Useful description | First comparison |
|---|---|---|
| Stuttering or low FPS | The game remains playable, but motion becomes uneven or controls feel delayed. | Compare a cold launch with the same scene after extended play. |
| Freeze | The picture or audio stops responding, but the app may still be open. | Wait briefly, then note whether the operating system reports the app as unresponsive. |
| Crash | The app closes or returns to the home screen. | Record whether it happens at launch, after restarting, or at a repeatable point. |
| Controller not detected | Touch controls work, but buttons or sticks do nothing. | Check whether the operating system sees the controller and whether another app receives input. |
| Confusing prompts | The game accepts input, but prompts or mapping screens do not show recognizable controller button images. | Inspect each binding manually and test one input at a time. |
A Google Play review dated September 23, 2026 reports crashes after restarting and mentions clearing RAM. An Apple App Store review dated September 24 says the game worked better after an update but lacked controller button images in prompts and mapping screens. These are individual, device-specific observations, not proof of a common cause or a fix that works on every phone.
Run the safe checks in this order
1. Install the newest store build
- Open Google Play on Android or the App Store on iOS.
- Search for Boltgun Boom and open its listing, rather than launching the game from a home-screen shortcut.
- If an Update button is available, install it over a reliable connection and wait for the installation to finish.
- Fully close the game, reopen it, and test the same level or action that previously produced the symptom.
- If the store shows no update, note the game version displayed in the listing or in the app’s information screen.
The September 24 Google Play note only says “Minor bug fixes and stability improvements.” Do not assume that the update specifically repairs stutter, low FPS, crashes, or controller mapping.
2. Restart the app and device completely
- Exit Boltgun Boom rather than leaving it suspended in the app switcher.
- Restart the phone or tablet using the operating system’s normal restart command.
- After the device starts, launch Boltgun Boom before opening other demanding apps.
- Repeat the same in-game action and record whether the result changed.
A restart can remove a temporary background-process or memory condition, but it does not establish the underlying cause. Treat a one-time improvement as a useful observation, not a permanent diagnosis.
3. Reduce competing load and heat
- Close games, video editors, camera apps, screen recorders, and other demanding software.
- Remove the device from direct heat and let it return to a normal temperature before testing.
- Use the same brightness, network state, and play location for each comparison where practical.
- Test first for a short session, then again after longer play. Note the approximate time when motion becomes uneven or the app exits.
These are isolation steps. The published Boltgun Boom material does not diagnose overheating or background activity as the cause of its performance problems.
4. Keep a reproducible record
For every test, record the device make and model, operating-system version, Boltgun Boom version, approximate minutes played, level or location, action that preceded the problem, and whether the controller was connected. A repeatable pattern is more useful to support than a report that the game is simply “slow.”

Diagnose stuttering and low FPS
Use a cold-versus-warm comparison
- Restart the device and launch only Boltgun Boom.
- Play the same section for a short, timed interval and describe the motion quality.
- Continue playing until the symptom appears, recording the elapsed time and device temperature by touch as cool, warm, or hot.
- Restart again and repeat the identical route or action.
If the problem appears only after longer play, heat or accumulated load is a lead for diagnosis, not a confirmed Boltgun Boom bug. If it appears immediately in one scene, record that scene and the action that triggers it.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsCompare with the controller disconnected
Quit the game, disconnect the controller, and relaunch Boltgun Boom using touch controls. Repeat the same test, then reconnect the controller and test again. This comparison can show whether the symptom follows the input path, but it cannot prove that the controller is reducing frame rate. No official source lists a controller-related performance defect.
Do not invent a graphics fix
The available official listings do not publish a graphics-options guide, device compatibility matrix, or measured FPS results. If your copy exposes graphics or frame-rate controls, change one option at a time and write down the original value; if it exposes none, do not assume that a hidden setting or a generic “booster” utility will help. There is no evidence-backed setting profile to recommend for particular phone models.
Distinguish network expectations from rendering problems
Frame-rate stutter is a rendering symptom, while a delayed online response would be a connection symptom. Boltgun Boom’s published mobile information does not provide a network diagnosis or performance benchmark. Describe exactly whether the picture is jerky, controls are delayed, audio stops, or the app closes so support can separate those cases.
Check storage and power conditions without overclaiming
Before testing, make sure the device is not displaying a system warning about critically low storage or power. Leave enough free space for the operating system and app updates, and compare a normal-power session with one in which a battery-saver mode is active. These checks can reveal a device-level condition, but Nitro Games has not published a Boltgun Boom requirement stating how much free storage, battery capacity, or charging power is necessary. Do not present a storage number or battery setting as an official FPS solution.

Capture the failure point
- Note whether Boltgun Boom closes, remains frozen, or returns to the operating-system home screen.
- Record whether the failure occurs at launch, after resuming, immediately after a restart, or during a particular level or action.
- Write down how long the session lasted and whether other apps had been used first.
- Restart the device and repeat the same sequence once, without changing several variables at the same time.
A Google Play reviewer reported crashes after restarting, but that report does not establish a universal restart-related defect. If the crash cannot be reproduced, retain the first observation and its circumstances instead of claiming that the restart caused it.

Avoid destructive troubleshooting without a reason
Do not clear app data, remove a purchase, or reinstall solely because a generic guide suggests it. Those actions can erase local state and do not have a documented Boltgun Boom-specific success rate in the available material. Ask Nitro Games support whether a data-reset step is appropriate for your device and account before using one.
Understand the cost and purchase boundary
The Google Play listing’s try-before-you-buy model lets you test the first three levels before a one-time purchase unlocks the full game. Use that trial portion, where available, to see whether the same crash or stutter occurs before spending money. A purchase may unlock content, but it is not a performance upgrade and should not be treated as a fix for low FPS or controller detection. Store pricing and purchase terms can change, so check the current listing for the amount and refund rules that apply to your platform.
Fix controller detection and mapping problems
Isolate the physical connection
- Close Boltgun Boom.
- Disconnect the controller, then reconnect it using the same Bluetooth or wired method you normally use.
- Check the phone or tablet’s operating-system Bluetooth or accessory screen and confirm that the controller is shown as connected.
- Test the controller in another app that accepts gamepad input. If it fails there too, the problem is outside Boltgun Boom.
- Relaunch Boltgun Boom only after the operating system reports the controller as connected.
The available sources do not identify a supported-controller list or confirm a universal mapping workaround. A generic Bluetooth mobile game controller may be relevant for the input portion of the game, but no specific model or compatibility claim has been verified. Do not buy a controller as a remedy for stuttering or low FPS.
Check the in-game mapping
- Open Boltgun Boom’s controls, options, or mapping screen.
- Select one action and press one controller input at a time.
- Save the mapping if the interface offers a save or apply command.
- Test the binding in a safe area of the game before changing another action.
- If one input works but another does not, record the exact button, stick direction, or trigger and whether the operating system recognized it.
Changing every binding at once makes it difficult to identify the failing input. Return to the original arrangement when a test is complete so later comparisons remain meaningful.
Work around unclear button images carefully
An Apple App Store review dated September 24, 2026 reports that controller button images are missing from gameplay prompts and the mapping menu, even though the game worked better after an update. If your interface behaves the same way, inspect the mapping labels and test a known input at a time. This report is anecdotal and does not show that every device, controller, or game build has missing icons.
Run a connected-versus-disconnected test
| Test state | What to record |
|---|---|
| Controller disconnected | Whether touch controls respond, whether the game stutters, and whether it crashes. |
| Controller connected before launch | Whether buttons are detected immediately and whether prompts or mapping labels appear. |
| Controller connected after launch | Whether the game notices the device without a relaunch. |
These observations help support reproduce the input path. They are not proof that one connection order is officially supported.

Do not confuse button labels with dead hardware
If a prompt lacks an icon, test the physical input in the mapping screen and in gameplay. A missing picture is an interface symptom; an unresponsive button, stick, or trigger is an input symptom. Test another app before replacing hardware, and note whether only one control or the entire controller fails. Avoid repeatedly remapping while the controller is disconnecting, because each reconnect can make the result harder to interpret.
Send a useful report to Nitro Games
Google Play lists Nitro Games support at [email protected]. Contact support when the problem remains after updating, restarting, reducing competing load, and repeating a controlled test.
Include all of the following in one report:
- Device make and model.
- Operating-system version.
- Boltgun Boom version or store build information.
- Whether the app was installed from Google Play or the App Store.
- Symptom type: stutter, low FPS, freeze, crash, undetected controller, or missing prompt images.
- Level, location, action, and approximate time played when it occurs.
- Controller model, connection method, and whether the operating system and another app detect it.
- Whether updating, fully closing the app, restarting the device, cooling it, disconnecting the controller, and testing again changed the result.
Keep the description factual. “The app closes after five minutes in level three on a specific device” gives support a reproducible lead; “the game is broken” does not. If possible, attach a short screen recording, but avoid capturing account credentials, payment details, or unrelated personal information. Mention whether the issue affects the trial levels or only content after purchase, since that helps support identify the exact build and game state.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Do not apply PC Boltgun troubleshooting to the mobile game
Focus Entertainment’s official PC Steam support material concerns the distinct Windows game Warhammer 40,000: Boltgun. Its file-verification, administrator-launch, and Steam Input instructions require Steam and a PC. They cannot be assumed to repair Boltgun Boom’s Android or iOS performance, crashes, or controller behavior.
What is currently known about performance
Boltgun Boom is a newly released mobile title, so store listings, reviews, update notes, ratings, and device support can change quickly. The available official material does not provide a detailed patch changelog, device-specific requirements, a controller compatibility matrix, or laboratory FPS measurements. Google Play’s displayed aggregate of 2.11K reviews and 3.4 stars is a volatile store rating, not a performance benchmark.
That limitation matters when choosing a fix: an update, restart, cooler device, or controller reconnect is a sensible diagnostic action, but none is an officially verified cure for every phone or tablet. Keep the device and build details with your observations, and recheck the current store listing when a new update appears.

Common troubleshooting mistakes
- Changing several variables at once: Updating, reinstalling, changing mappings, and switching controllers in one session prevents you from knowing what changed.
- Calling every hitch low FPS: A crash, freeze, audio stop, or delayed input needs a different report and test.
- Using PC instructions: Steam commands and Windows file checks do not apply to the Android or iOS app.
- Buying hardware first: A Bluetooth controller may improve comfort, but no source verifies a model or promises better frame rate.
- Overreading a store review: Individual comments can reveal useful symptoms, but they are not controlled tests or proof of a universal bug.
- Clearing data immediately: This may remove local state and has no documented game-specific success rate.
- Testing while the device is hot: A result from a heat-soaked phone is difficult to compare with a cool launch.
A practical decision path
- Update: install the current store build and note its date or version.
- Restart: fully close the game and restart the device.
- Stabilize: close demanding apps and test with the device cool.
- Classify: decide whether the symptom is choppy motion, a freeze, a crash, or input failure.
- Compare: repeat the same scene, first without and then with the controller when input is involved.
- Document: record device, OS, build, duration, location, action, and connection method.
- Escalate: send those details to [email protected] if the symptom persists.
Frequently Asked Questions
Is Boltgun Boom the same game as Warhammer 40,000: Boltgun on Steam?
No. Boltgun Boom is Nitro Games’ Android and iOS adaptation released September 23, 2026. Steam file verification, administrator launch, and Steam Input instructions concern the separate PC and console title.
Did the September 24 update definitely fix low FPS or controller problems?
The Google Play note says only “Minor bug fixes and stability improvements.” It does not name an FPS, crash, or controller fix, so test your own device after updating.
What phone specifications does Boltgun Boom require?
No official device-specific requirements, compatibility matrix, or frame-rate benchmarks were published in the listed materials. Record your exact model and operating-system version when reporting a problem.
Should I buy a Bluetooth controller to fix stuttering?
No. A generic Bluetooth mobile controller is relevant to input, but no specific model or performance benefit is verified. Buy one for control preference, and confirm compatibility with your device and the game.
Will clearing RAM or reinstalling stop crashes?
A reviewer mentioned clearing RAM, but that is an individual observation, not a confirmed fix. Reinstalling or clearing data can remove local state, so ask Nitro Games support before using destructive steps.
What should I send Nitro Games support?
Email [email protected] with your device and OS, store platform, game build, symptom, level or action, elapsed play time, controller model and connection method, and the tests you already completed.
Can missing controller button pictures be fixed in settings?
An Apple review reported missing button images in prompts and mapping screens. Inspect labels and test one input at a time; no universal settings workaround has been confirmed.
Recommended Free Tools
The Bottom Line
Update Boltgun Boom, restart the app and device, test with competing apps closed and the device cool, then classify the symptom. Compare the same scene with the controller disconnected and connected, avoid PC-specific Boltgun instructions, and do not assume a generic booster, controller purchase, or reinstall will cure performance. If the issue persists, send Nitro Games a reproducible report with your device, OS, build, timing, level, and connection details.
