I have a syncmaster 20" monitor with native resolution of 1600x1200. I have a 8800GTS 320MB GPU. When I go to play Team Fortress 2 I have the option to let the GPU scale to 1600x1200 or let the monitor handle it. Which is better?
I'm new to pc gaming but I know it varies in the similar situation of cable box and TV. Sometimes the cable box is better at handling the scaling and sometimes the tv.
It sounds like either way you'll get the 1600x1200 resolution since it's your monitor's native res. The only difference between the two is that w/ the GPU scaling, you are forcing the game to run in that resolution. I think this means that even if your monitor was a 1280x1024 native res, you could still force it to run as 1600x1200. I don't think either will impact performance if that's what you're asking, but I've been wrong before.
