I don’t want to pay for the hardware either. I have an old 750 Ti, and you would be surprised how many (not new) games are running perfectly fine on it. Amount them those like the last deus ex games. I don’t remember the framerate I had, but neither do I remember it as an unplayable laggy mess.
When I read that CS2 barely manages to run on a 2060 or some other powerhouse (in my eyes at least, but honestly for some reason I have the impression that 20xx is not much of a leap from let’s say a 1080 Ti) I can’t think anything else but that the game is a totally wasteful garbage technically.
