KovaaK's performance tweaks

Everything below was tested on my AMD system. A different AMD CPU, SMT setup, or any Intel CPU WILL behave differently, so treat these results as a reference and test the tweaks yourself.

Test system

• Ryzen 7 9800X3D
• RTX 4080 Super
• 32 GB DDR5-6000 CL30
• 2560x1440 native res
• Windows 11 Pro build 26100 Atlas OS
• Benchmark tool - CapFrameX

0.1% low	814.5	1,137.1 (+39.6%)	1,427.1 (+75.2%)

Each comparison uses the better (higher lows) setting from the previous step.

Test changes one at a time.

1. One Thread Frame Lag

Open Video settings and enable One Thread Frame Lag. This is the starting point for every next benchmark.

Personally, I don't feel any difference when it comes to the input lag. I've been playing with OTFL for a long time, maybe I've just got used to it.

2. Engine.ini

Caution

If you experience any issues after applying the Engine.ini please read the Known Issues section, or simply delete the Engine.ini file to bring it back to the default state on next Kovaaks launch.

Copy configs/Engine.ini to %LOCALAPPDATA%\FPSAimTrainer\Saved\Config\WindowsNoEditor, replace the existing file, then set it to read-only. The Engine.ini "guide" has the backup step and common fixes.

0.1% low	839.1	912.1	+8.7%

3. CPU affinity

First, open Task Manager, then Performance, then CPU. Check Logical processors and leave every CPU enabled except CPU 0 and CPU 1.

Intel, P/E-core systems, 8 or 32 threads - it all needs its own testing. Disabling 0-1 should be fine for most 8 cores 16 threads AMD CPUs.

Use one of these methods:

1. Process Lasso: start KovaaKs, right-click FPSAimTrainer-Win64-Shipping.exe, select CPU Affinity -> Always -> Select. Untick CPU 0 and CPU 1, then apply.
2. Process Governor: download the latest release, run it as administrator, find FPSAimTrainer-Win64-Shipping.exe, right-click it, and choose Add Process Rule. Set Selector By to Name, Affinity to the range for your CPU, such as 2-15, set Force to Y, then save.

Average FPS	1,563.9	1,584.5 (+1.3%)	1,626.0 (+4.0%)

0.1% low	902.9	1,025.8 (+13.6%)	1,055.8 (+16.9%)

4. Disable SVM and IOMMU

Those are bios options, every motherboard has them in a different place so you have to find them on your own.

If you play Faceit/ Valorant (League of Legends too, I think, since the AC update), you have to have both of those settings ON, you won't be able to play without them.

0.1% low	997.3	1,137.1	+14.0%

5. Render scale

If you don't mind a slightly softer image (I wouldn't call it blurry, at least when you use normal values), you should try lowering your render scale a bit. It can help quite a bit without degrading the quality that much (if you are on 1440p+, I haven't tested in on lower native resolutions).

Final words

Your hardware, system optimizations, and other stuff WILL change the result. Test one tweak at a time and keep only what makes a real difference for you.
