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 almost certainly, but you can confirm by running a game and checking your CPU metrics on a resource monitor while in casual or something. One thing to test is adding the “-threads [threads_number]” for how many cores you have and see if that helps.
Also check ProtonDB for user performance tricks.
The big reason for CS2 getting laggy from CPU being weak is from the number of threads the game runs to keep the inputs from all the players as live as possible. Increasing the power or number of threads improves the perceived lag you’re seeing.
Seconded, it’s absolutely the CPU. This is a CPU that’s nearly as old as the original Intel core lineup. DDR 3 and pcie 2. And worse performing generally. Spending $100 on someone’s second-hand mid-2010 system. Paired with that graphics card should be wildly adequate. My main system runs a sixth generation i7 with an RX 580 overclocked. It isn’t playing Doom the Dark Ages or most recent games maxed out, but it’s no slouch.
I have a system of a marginally older vintage. A core 2 quad with 4 threads and a gtx 560. Also DDR 3 and pcie 2. It would be physically impossible for a system of those specs to even make use of most of an AMD 6700. The system bus alone would be bogged down, trying to even feed the GPU a fraction of what it can take. Not even counting other processing overhead.
PBR rendering is demanding on data rate. Way more than gourad shading or basic MIP mapped textures. Double the data or more.
