I just recently bought Thief 3 and found it to be horribly slow with regards to frame rate. I have a home built system with a Pentium 4 2.8 GHZ (not overclocked) sitting on an ASUS P4P8X motherboard with a brand new ATI Radeon 9800 PRO and 1 GB of DDR3200 memory from Kingston. Sometimes this thing looks like a damn slideshow, and my system is no weakling when it comes to graphics. I have heard that Omega drivers are another option when it comes to drivers for the video card (I currently have Catalyst 4.11 installed). I have Far Cry on here and that seems to run just fine with no chop. Any suggestions or anyone out there have the game and know what I'm talking about??
