So pretty much need to know what are my best settings to play games smoothly on this pc I have tried so many different tutorials and videos and for some reason my tony hawk game (underground 2) there is never a floor and you can see the sky through every wall and flloor like in this screen shot I took right here


Edit: fixed a number on a spec

I haven't tried that game yet, but I had a similar problem with Tony Hawk 3. Go into Emulator Settings and set the preset slider on the bottom to Safer, or Balanced and see if that fixes it.

EE rounding should be Chop and VU to Nearest, but you could try Negative, just in case that helps.
