I used to play on 1080p low settings with 150-200 fps in CSGO and in CS2 I get 100-180 on 800x600. When I record it drops to 60-70.
Most of the people who have stopped playing in my friends list have done it because on low settings in CS2 you can't see anything. The game is going to slowly get better, but how exactly are players supposed to even run it?
I feel like Valve added way too much unnecessary stuff in CS2 like the shadows and light sources everywhere, legs, tracers, impact smoke puffs, et c.
CS is a simple game that Valve is trying to make into some kind of modern shooter to attract people who are more likely to buy their shiny skins, but I can tell you one thing about CS-the most dedicated players really couldn't care less, and had Valve fully supported games like 1.6 and CSS, they would still have thriving communities, in fact they still do despite Valve. The reason Valve will not do this is because games like 1.6 will not make money for them because they cannot sell skins for it, and that is why they are currently taking control of customisations in CS2 early so that they make even more money from it than from CSGO, because community servers had plugins for skins in CSGO. I am positive that Valve will implement a system in CS2 that does not allow custom server plugins when they decide to allow workshop maps and community servers.
