So ill admit, CS2 never ran perfectly in windows either, and with everything having to be “shiny” and new all the time and with updates the game was bound to get laggy.
However I do wonder, is it the fault of my 15 year old amd fx cpu, or is it linux? I have a gtx 6700 gpu which should be plenty overkill for cs2. But ive heard cs2 is processor heavy. Im also still on ddr3, 32 gb.
It’s your CPU. If you are up for purchasing new hardware, a Ryzen processor (5000 series or better) will be a massive upgrade and are very prevalent on the used market.
