Jeo said:I'm trying to start PC gaming so I downloaded the Portal demo from Steam to see if I could run Team Fortress 2 without any problems, it was all good until I raised my resolution. The game was sluggish and response was slow. Why does the game run better at 1200x800 than 1680x1050? And how can I improve my computers performance?

Thanks in advance
Your video card is the weak link. You can get a <$100 card that will massively increase your performance. I think the 9100 is an integrated card actually.
The game runs better at 1200x800 because there are less pixels to render than at 1680x1050. Think HD vs. SD (even though those are both high resolutions).
