Most of the games we have now (especially single player games) need a minimum of 8-10GB of VRAM. Pero you can still play some of these recent games but not more than 60-100FPS. For FPS games, you can look into games like DOOM (2016 or Eternal) or CSGO, if you're feeling confident try out Overwatch 2 too, but make sure your settings are set to Low or Very Low.
