The games default textures are nothing, so RAM nor GPU memory are very important, but the post processing effects can be demanding, especially there implementatio of SSAO. The game itself is currently runs better with faster CPU speeds than more cores, so do what you can to allow for maximum boost so that you're getting +3GHz for at least the first 2 cores of your CPU. Also try running in Vulken mode as well as trying the exclusive fullscreen launch options. Depending on you setup those can net you up to a 10% performance boost. Also try playing on someone else's server so there's less load on your system. I plan on making a guide of sorts in the future, but the public test is too fun to pass up even though hardly any optimization mods work with it. 😊
