A guide on how to get more FPS in PR.
Launcher ---> Options ---> Video:
Disable Anti-Aliasing
Launcher ---> Options ---> Graphics:
Disable `Use advanced shaders` to enable old GPU support
Set all `Increase XXX LOD` bars to the lowest value and disable `Fade Vegetation LOD`
Set all graphic settings to low, dynamic shadow & lighting to OFF
Launcher ---> Options ---> Audio:
Change audio quality to medium/low
If it is still not enough:
Launcher ---> Options ---> Video:
Reduce resolution
Reduce View Distance Scale
If it is still not enough:
You are not meeting the minimum requirements to run PR
-----------------------------------------------------------------------------------------------------------------------------------------
If your computer has both integrated and discrete GPUs, open Start -> Settings -> System -> Display -> Graphics. Then add desktop app prbf2.exe and set it to high performance with your discrete GPU.
-----------------------------------------------------------------------------------------------------------------------------------------
If you are using an Intel CPU with updated microcode and BIOS, you might experience lower than expected fps due to the way Intel implements workarounds to spectre/meltdown vulnerabilities.
You can mitigate this performance issue by disabling the bit that controls spectre/meltdown vulns via a software called inSpectre.

Note: Please DO NOT do this on your work laptops or PCs with sensitive information, only do this on your home/gaming computer.

Stuttering on some Ryzen CPUs and Threadrippers (and maybe old Core 2 Quads)
Set PRBF2.exe affinity to just two threads that exist within the same CCX/CCD/chiplet, or enable CPPC CTRL and CPPC Preferred Cores.
Some chips are using MCM/chiplets that have a far slower bandwidth between them compared to the bandwidth between the cores within the same cluster of CCX, causing microstutters.

- Enable XMP/DOCP/EXPO
- Enable TVB (Intel) or PBO AutoOC (AMD)
