I'm not surprised. On the last days of my 1050ti build, I was playing CS2 and got like 70 FPS with very bad stuttering. I built a new PC with a 4070 and can run the game on 400+ FPS on my optimal settings, but I should not have had to do that. All of the CS games were known for running on potato PCs. I have a friend with an RTX 2070 and another one with a 3060, and neither of them can even run CS2 properly.
Valve has become more and more incompetent with CS. I have heard of their management being like "guilds" which micromanage themselves, but I think they are focusing all their resources on Deadcock (which I played and did not find fun at all, was not my kind of game). I heard a rumor that there are literally under 10 people on the CS2 dev team right now, and maybe 1 or 2 people working on their anticheat. Shit fucking sucks.
