I'm really confused. Since day one, this damned thing has given me trouble. I ran a couple games on vista, only to get extremely poor frame rates and such. Vista would take forever to do things (Though I blame that on the processor).
Here is where it gets confusing. I set up a dual boot with Ubuntu (Ubuntu ran MUCH faster.), and it does the same exact thing, with the same exact frame rates. (poor frame rates even in Half-Life based games, though I noticed frames would drop most when grenades/explosives went off, which also made me think it was a processor thing.)
In Source games, fps would boost up when backed into a corner, no matter what map.
Specs:
1.6ghz Intel Celeron 420
1gb RAM
Integrated Intel_945GM (Or some video similar to it, I'll boot up Vista and see what DxDiag says later.)
Blockland and Warsow run fine for whatever reason.
