I got access to the beta yesterday like a lot of other people and I was surprised to find that the game ran horribly on my PC. The FPS numbers are a bit lower than I would expect at an average of 90 but the actual dips are horrendous and it hangs for seconds at a time making it pretty much unenjoyable.

Specs: Ryzen 2600 with moderate overclock. RX 6700 XT, 16GB dual channel RAM at 3000MHz, 1440p resolution.

Monitoring utilization during a deathmatch game shows that nothing is exceeding 50% util (CPU, GPU, RAM or VRAM usage) at 2560x1440 no super resolution on medium-high settings. CPU util is roughly 35-40% most of the time which seems to be the main issue. Lowering graphical settings or resolution doesn't impact FPS noticeably. CSGO and other games run as expected.

It's kinda behaving as if multicore is disabled but from what I could find that's not a setting in CS2 and it should be always enabled. Anyone encounter similar issues? I know the Ryzen 2600 is a little old but benchmarks show comparable CPUs closer to 200 FPS.

Edit: Found something that helped with the hangs/stuttering. FPS is still not great but at least the game is playable now. Find cs2.exe under the default install path of C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\game\bin\win64 -> Properties -> Compatibility -> Disable Full Screen Optimizations
