I can only play older games that have low-quality graphics. The current games that I have are:
Counter Strike 1.6
Unreal Tournament GOTY (1)
Quake III Arena
Unfortunately, I can't even play Halo (1) on its lowest settings. Neither GTA: VC.
Please don't pity me lol. I know it sucks but I can play all browser-based games perfectly fine with no lag.
What can your computer play?
