Okay, I'm becoming desperately close to buying a new video card after 3 weeks of messing around, trying to make Doom 3 work. No one else seems to have this problem so I've been shooting in the dark trying to solve my problem.
Everytime I play the game I get massive graphic corruption whenever I enter certain rooms. Not just artifacts or snow but complete texture corruption. It's been frustrating. Here are my specs:
Barton AMD Athlon XP 3000+ (Stock)
ASUS nforce2 A7N8X-X MB
Sapphire Atlantis Radeon 9600 Pro w/ 256MB DDR (Stock)
2x512 PC3200 Memory
MAG Innovision 770FS Monitor
Here are most of the things I've tried:
1) Tried 4.8 Cats, 4.9 Beta Cats, and Omega v2.5.58
2) Tried Directx 9.0b AND Directx 9.0c
3) Reseated the video card in the AGP slot
4) Reseated the memory and ran MemTest and MemoryDiag
5) Underclocked the video card to 300MHz core and 175MHz memory
6) Replaced 300W powersupply with 420W power supply
7) Installed side panel fan for possible heat problems
8) Tweaked everything in the config file that I could using tweakguides.com as my reference source
9) Changed voltages for AGP Slot, tried 1.5, 1.6, and 1.7
10) Turned off Fast Write and Write Combining
11) Turned hardware acceleration down 2 notches
12) Turned down AGP Speed from 8x to 4x (Also disabled 8X support in BIOS)
13) Underclocked Athlon XP 3000+ from 2.2GHz to 1.7GHz
14) Set AGP Aperture Size to 64MB
15) Set all OpenGL texture preferences to High Performance
16) Set PC away from any outside electrical interference
17) Checked heatsinks on video card after a few minutes of playing and noticed it was not hot to the touch even after corruption started
18) Re-installed Doom 3
19) Reformated hard drive and clean installed all drivers
