The headline’s 15% gain is a claim, not a result readers should expect: the available account does not identify the PC, games, settings, benchmark method, or repeated tests behind it. Windows and firmware configuration can be investigated without buying hardware, but there is no evidence here that any particular change reliably raises gaming performance across systems. The useful approach is to measure your own games before and after one change at a time.
What the 15% figure does—and does not—tell you
The title describes a Windows gaming optimization story involving Windows and BIOS settings. The accessible account does not establish how the 15% was calculated or whether the result was reproducible. It provides no test machine, game list, graphics settings, benchmark tool, baseline method, or controlled before-and-after comparison.

That means the figure cannot be treated as a published benchmark, a typical outcome, or a promise that a reader can reproduce it. Nor does the available evidence identify a specific setting responsible for the claimed improvement. Without the original test details, attributing the number to an individual tweak would be speculation.

How to check whether a change helps your PC
A settings adjustment is only useful if the comparison isolates its effect. Keep the game, scene, resolution, graphics options, and other conditions consistent, and change one setting at a time. Record both average frame rate and frame-time consistency where your measurement method provides them; a higher average alone may not describe how smooth play feels.
#1 Best Overall
- POWERHOUSE 8-CORE GAMING PERFORMANCE — Driven by the AMD Ryzen 7 8700F with 8 cores and 16 threads, boosting up to 5.0 GHz for smooth, responsive gameplay and the ability to handle AAA titles, streaming, and background tasks all at once
- NEXT-GEN BLACKWELL ARCHITECTURE — The NVIDIA GeForce RTX 5070 is powered by NVIDIA's cutting-edge Blackwell GPU architecture, delivering a massive generational leap in rasterization and ray tracing performance so you can experience your games the way they were meant to be played.
- Simplistic Design: Enjoy the latest generation of Windows 11 Home for your everyday needs. *MSI recommends Windows 11 Pro for business use.
- Cool While Gaming: In conjunction with an ARGB fan Air Cooler, the Codex R2 features four system cooling fans; three in the front and one in the rear to pull in cool air and push heat out of the PC.
- Turn on the Bright Lights: With the built-in RGB lighting, take your gaming experience to the next level by pressing the MSI LED button to cycle through lighting options. Customize lighting even further with MSI Center software.
- Establish a baseline. Choose a repeatable in-game scene or benchmark and record the current settings and performance.
- Change one setting. Note exactly what you changed, including whether it was a Windows or BIOS setting.
- Repeat the same test. Use the same game, scene, resolution, graphics settings, and measurement approach. Repeat runs so a single unusually good or bad result does not decide the comparison.
- Compare and check stability. Look at average frame rate and frame-time consistency, and confirm that the system and game remain stable.
- Keep or reverse the change. If the result is unclear, unstable, or comes with a security or usability trade-off, restore the prior setting.
For a quantitative claim that others can assess, report the PC configuration, game, graphics settings, resolution, measurement method, and results across repeated runs. If several settings change together, the test cannot show which one produced any difference.
What can responsibly be concluded
A no-cost configuration change may be worth testing on an individual PC, but the evidence available for the 15% claim does not validate that figure or establish a universally effective Windows setting. The original publisher page and current Microsoft technical guidance were not available in the retrieved material, so precise version-specific instructions or recommendations for particular Windows and BIOS options cannot be substantiated here.
