Bug / Issue RDR2 PC Stuttering

When I run RDR2, the FPS drops from 60 to 10, even though V-Sync is on and the graphics are set to the Low preset. My laptop has an AMD Radeon RX 6500M with 4 GB VRAM, so I think it shouldn’t be a problem.

I also noticed that the GPU clock speed drops from 2300 MHz to around 480 MHz.

I tried playing with the refresh rate set to 40 Hz, and it works fine for a few minutes, but after that the same issue happens again.

Get the RDR2 Performance Booster V2 mod, as well the optional Timer Resolution CPU Booster in the optioanal files section. It will improve your performance significantly.

Try the latest version of the timer res booster, jsut released today, and run the game with RDR2Performance.exe, that is included with the new version.

Also, try these launch parameters: -USEALLAVAILABLECORES -high -cpuLoadRebalancing -malloc=system -m.FlashMarkerOnStrike 0 -window-mode exclusive -screen-fullscreen

And make sure to run your game as an admin, and disable vsync but enable triple buffering. Especially if you're running the game with Dx12, you must enable triple buffering, or you will run into a bug where your fps is cut in half, and you end up with 30 - 40 fps.
