For a game developer, Snapdragon Game Super Resolution (SGSR) is the main upscaling path: configure it in Unity or Unreal Engine, or integrate it in native rendering code. Frame generation is separate. Adreno Neural Fusion (ANF) can generate intermediate frames in a native Vulkan integration, but Qualcomm’s current Unity ANF package is for Super Resolution and explicitly does not include frame generation. Players generally cannot turn either feature on with a universal Android setting; Windows Snapdragon PC users have a separate option, Microsoft Auto SR, for supported games.
What do “AI upscaling” and “frame generation” mean on Snapdragon?
Upscaling renders a game scene at a lower resolution and processes it to produce an image at the intended output resolution. Its purpose is to reduce the cost of rendering the scene at full resolution while preserving as much visual quality as the chosen technique can. Frame generation is different: it creates an additional intermediate scene frame from information about frames the game has already rendered. Neither term describes a general switch that applies automatically to every Snapdragon game.

For Qualcomm’s game-rendering tools, the main distinction is between SGSR upscalers and ANF techniques. SGSR is integrated by the game developer through an engine package or native rendering code. ANF Super Resolution and ANF Frame Generation have different inputs and resource requirements; using one does not mean the other is enabled.
How the techniques differ
- SGSR 1.0: a spatial, single-pass upscaler. It does not use temporal history.
- SGSR 2.0: a temporal upscaler. Qualcomm described it as an implementation of temporal anti-aliasing and upscaling (TAAU) in its October 22, 2024 announcement. It uses temporal inputs and offers two-pass fragment and three-pass compute paths.
- ANF Frame Generation: a native Vulkan technique that uses consecutive rendered scene frames, depth, and motion vectors to create an intermediate scene frame.
- Microsoft Auto SR: a Windows operating-system feature for supported Snapdragon PCs. It is a separate route from SGSR and ANF, and uses DirectX rather than Vulkan.
These tools are aimed at different integration layers. The table is a quick way to identify which path fits the project before changing settings.

Can I turn on Snapdragon upscaling in a game as a player?
Usually not through a device-wide Android control. SGSR has to be integrated into the game by its developers, so a player can use it only when the game supplies that implementation and exposes the relevant graphics options. Installing an SDK package or changing a Unity project setting is developer work, not a way to add SGSR to an unrelated finished game.
On Windows, Auto SR is the exception to the “developer integration required” rule: it is an opt-in OS feature that can be enabled for eligible games. It does not turn on SGSR or ANF, and its graphics API and platform requirements are different. Instructions for that route appear below.
How do I enable SGSR in a Unity game?
In a Unity project, install the SGSR package, enable Unity’s upscaler framework for each build target, select the upscaler in the active URP asset, and enable post-processing on cameras that should show the result. The SGSR Unity package lists Unity 6 (6000.3.x) or later and URP 17.3.0 or later as requirements. Check the package’s current README against the versions actually installed in the project before integrating it.
- Install the package. Add the official
com.qualcomm.snapdragon.sgsr.for.unitypackage through Unity Package Manager or the Git URL documented by the package. - Enable the framework symbol. Open Edit → Project Settings → Player → Other Settings → Scripting Define Symbols. Add
ENABLE_UPSCALER_FRAMEWORKfor every build target you intend to use. A symbol set only for one target will not automatically configure the others. - Choose a URP asset and render scale. Open each active Universal Render Pipeline asset. Set its Render Scale; the SGSR README gives
0.6667as an example, not a universal recommended value. - Select an SGSR mode. In the URP asset, choose SGSR 1.0 Spatial Upscaler, SGSR 2.0 Temporal Upscaler (2-Pass FS), or SGSR 2.0 Temporal Upscaler (3-Pass CS). The available options reflect different processing paths; measure their image quality and GPU cost on the target device.
- Configure the generated options asset. The package creates an SGSR options sub-asset. Set its options for the intended project rather than assuming the default configuration is suitable for every scene.
- Enable camera post-processing. For each camera whose output should be upscaled, open its Inspector and turn on Rendering → Post Processing. A project-level selection alone does not enable the effect on every camera.
- Run and inspect the scene. Enter Play mode, then use Unity’s Rendering Debugger to inspect and tune the effect. Validate the output on the target Snapdragon device as well as in the editor.
Which SGSR mode should a Unity project start with?
SGSR 1.0 is the simpler spatial path: it does not depend on temporal history. SGSR 2.0 can use information across frames, which makes the quality of temporal inputs important. When testing SGSR 2.0, pay particular attention to motion vectors, depth/history validity and regions newly exposed by movement, where previous-frame information may no longer describe the visible scene.

Render scale is a quality/performance decision, not a promise of a particular frame-rate gain. A lower internal resolution reduces the amount of scene rendering, but the resulting image and GPU cost depend on the game, device, scene and selected path. Compare paths under the same scene and output conditions rather than treating the README’s example scale as a benchmark result.
How should the interface be handled?
Keep important 2D interface elements at device or native output resolution where practical. If UI is rendered into the lower-resolution scene and then upscaled with it, text and fine interface lines can look softer. A common rendering design is to upscale the 3D scene first and composite the UI afterward, but the project’s render pipeline determines how that is implemented.

For Unreal, use the Snapdragon Game Plugins repository branch that matches the project’s Unreal Engine version. The plugin catalog lists SGSR 1 and SGSR 2 for UE 4.27 and UE 5.0 through UE 5.8. Do not assume a plugin branch built for one engine release is interchangeable with another.
- Match the plugin branch to the engine. Select the repository branch for the project’s Unreal Engine version, then follow that branch’s installation and project configuration instructions.
- Select the SGSR implementation. SGSR 2 offers a two-pass fragment path and a three-pass compute path. Choose the path to evaluate; do not infer that one is faster or visually better on every GPU from its name alone.
- Validate temporal inputs. For SGSR 2, inspect motion vectors, jitter behavior and disoccluded regions, where camera or object movement reveals pixels that were hidden in a prior frame.
- Profile on the target device. Compare image quality and GPU time on the actual Snapdragon device and representative gameplay. Confirm that UI remains readable and that scene transitions or fast motion do not produce unacceptable artifacts.
The same plugin catalog lists ANF for UE 5.0 through UE 5.8 on Android Vulkan. It describes ANF Super Resolution and Frame Generation as independently selected techniques. This means selecting a super-resolution option is not itself a frame-generation setting; verify the plugin’s version-specific configuration and the target device’s runtime support.

How can a game use ANF Frame Generation?
ANF Frame Generation is a native integration path, not a Unity setting in the currently documented ANF Unity package. According to the current Snapdragon Game Studios SDK README, native integration requires Android arm64-v8a, Vulkan, and Snapdragon 8 Elite Gen 6 or higher. The SDK also requires runtime support checks and a fallback for cases where the technique is unavailable.
Frame generation needs a rendering contract that provides the information the technique uses. The SDK describes an intermediate scene frame generated from consecutive rendered scene frames, depth and motion vectors. The game must also decide how to present interface elements: render or composite UI separately for rendered and generated frames so that interface content is not treated as scene motion.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteNative integration sequence
- Package the SDK library and license. Include the ANF components and license as directed by the SDK documentation for the application’s Android build.
- Query technique requirements. Check the device and runtime’s supported techniques before attempting to create or dispatch Frame Generation.
- Create Vulkan with the required capabilities. Enable the required extensions and queue capabilities specified by the SDK contract.
- Register handles and verify support. Provide the required Vulkan handles, then verify that the intended technique is available for the current runtime and device.
- Create technique resources. Allocate and configure resources using the SDK’s requirements for the selected technique and the game’s image, depth and motion-vector data.
- Dispatch Frame Generation according to the contract. Supply valid consecutive-frame inputs and integrate the generated scene frame into the presentation sequence.
- Keep a fallback path active. If the runtime query fails, required resources are unavailable, or the feature cannot be used for the current configuration, render without ANF Frame Generation.
The SDK’s capability query matters because device family alone is not a safe substitute for checking the current runtime. Support should be established at run time, and the game should remain functional when the technique is absent. The cited minimum hardware is the generation named in the current SDK README; it should not be generalized to every Snapdragon device or treated as a guarantee that every game configuration will support the technique.
Does the ANF Unity package include frame generation?
No. The current ANF Unity package README explicitly says, “Frame generation | Not included in this package.” It is an ANF Super Resolution package for URP, not a Unity wrapper for ANF Frame Generation. A project that needs ANF Frame Generation must use a supported integration path other than assuming the Unity package provides it.

The Unity ANF Super Resolution package has a stricter configuration contract than the general SGSR Unity package. Its stated requirements are Unity 6000.6.2f1 or later, URP 17.6.0 or later, Android ARM64, IL2CPP, and Vulkan only. It supports one active view and excludes XR and dynamic resolution. It also requires supported color, depth and motion-vector formats.
For this package, the render scale must be exactly 0.5 so input and output have an exact 2x relationship. Do not apply that constraint to ordinary SGSR settings: it belongs to the ANF Unity Super Resolution package. Likewise, do not assume that satisfying the Unity version requirement alone makes the package work; renderer, API, build backend, view count, formats and scale all need to match.
How can players enable Auto SR on a Snapdragon Windows PC?
On a supported Snapdragon X or X2 Copilot+ PC, Microsoft Automatic Super Resolution is an OS-level option that can be enabled per game. Microsoft’s documentation describes it as opt-in, not enabled by default. It is separate from SGSR and ANF and supports DirectX 10 or later, not Vulkan or OpenGL.
Enable it in Game Bar
- Launch the game and open the Game Bar.
- Open the Display → Auto SR widget.
- Enable Auto SR for that game, then use a supported in-game resolution if required.
Enable it in Windows Settings
- Open Settings → System → Display → Graphics.
- Select the game from the app list, or add it if necessary.
- Open that game’s graphics options and enable Auto SR where the option is available.
Microsoft’s listed conditions include Windows 11 version 24H2 or later, current graphics and neural drivers, and a supported display at 1080p or higher. Auto SR does not support Vulkan, OpenGL, DirectX 9 or x86-only games. If the setting is unavailable, check the Windows release, drivers, game API, executable architecture, display and game resolution before concluding the PC lacks the feature.
How should you test image quality and performance?
There is no universal FPS, latency or battery-life figure established for all Snapdragon games. Results depend on the device, scene, render scale and implementation. A comparison is useful only when it holds those conditions steady and evaluates both visual output and GPU cost.
- Use a representative scene. Include fast camera motion, moving objects, fine geometry, high-contrast edges and areas that become visible after occlusion.
- Compare like with like. Hold output resolution, scene, device, quality settings and measurement conditions constant when comparing native rendering, SGSR modes or other supported paths.
- Inspect the artifacts that match the technique. For a temporal upscaler, check motion vectors, jitter and newly revealed regions. For Frame Generation, assess whether generated scene motion and separately composed UI remain coherent.
- Measure GPU time and delivered frames. Record results on the actual target device; do not extrapolate a single scene or device result to all Snapdragon games.
- Test fallback behavior. Confirm that a runtime support failure or incompatible configuration returns the game to its non-ANF rendering path rather than preventing launch or presentation.
- Inspect debugging output. Use Unity’s Rendering Debugger for SGSR tuning, plus the engine or SDK’s available diagnostics for the specific integration.
Why might the feature not appear or produce the expected result?
Most failures come from using the wrong integration path or missing one part of its contract. Identify whether the project is using SGSR, ANF Super Resolution, native ANF Frame Generation, or Windows Auto SR before troubleshooting; their settings are not interchangeable.
- SGSR is selected but absent in Unity: check the package installation,
ENABLE_UPSCALER_FRAMEWORKfor the active build target, active URP asset, selected upscaler and camera post-processing. - Only some cameras show the effect: enable Rendering → Post Processing on each intended camera and verify the active pipeline configuration.
- SGSR 2 looks unstable in motion: inspect motion vectors, jitter and history-dependent areas, especially newly disoccluded pixels.
- ANF Unity Super Resolution does not initialize: verify the package’s Unity and URP versions, Android ARM64/IL2CPP build, Vulkan API, one-view limit, disabled XR/dynamic resolution, supported formats and exact
0.5render scale. - ANF Frame Generation is unavailable: check Android ABI, Vulkan capabilities, supported hardware and the runtime support query. The current Unity ANF package does not supply this feature.
- Auto SR is missing in Windows: verify Windows 11 24H2 or later, current graphics and neural drivers, eligible hardware and display, and a supported game API and executable architecture.
SGSR package release history helps distinguish the tool’s generation from a particular game’s support: Snapdragon Game Studios lists SGSR 1.0.0 on June 29, 2023; SGSR 1.1.0 on January 29, 2024; and SGSR 2.0.0 on October 21, 2024. These are package release dates, not evidence that a given title or device includes the feature.
Frequently Asked Questions
Can I combine SGSR and ANF Super Resolution in the same rendering pass?
The documented materials describe distinct integrations and do not establish a supported stacked configuration. Treat them as alternative paths unless the specific engine plugin or SDK version explicitly documents a combination.
Does SGSR 2.0 automatically create extra frames?
No. Temporal upscaling uses information across frames to reconstruct an output image; it is not the same operation as generating an additional intermediate frame. Frame generation is a separate ANF technique with its own inputs and integration requirements.
Does buying a Snapdragon phone or handheld add SGSR to a game?
No hardware purchase by itself adds the rendering integration to a title. The game must include the appropriate implementation, and the relevant runtime and device constraints still apply.
