Ti4600. I decided to purchase it at Circuit City just in case I needed to
return it. My system specs are: Asus P4PE w/ 2.66 P4 running at 3.0 Ghz.
512MB of Samsung PC2700 DDR333 memory running at 385mhz. The PCI and AGP
are fixed at the default speed. No overclocking on either video card.

2 different fps numbers, the first is start of practice session sitting on
pit road, the other is last car in a full field at start of race as engines
are started.

All testing on the Ti4600 was completed using the 40.71 drivers, and the ATI
was using the latest 3.0 Catalyst drivers.
All above numbers came from uninstalling the Ti4600, and installing the ATI
in the same OS (WinXP Pro w/ SP1).
I then reformatted and reloaded WinXP Pro, installed all service packs and
updated drivers, installed DX9.0, then installed the ATI card drivers (3.0
Catalyst).
I tested once again at the same track, same options turned on, see below:
Direct3D 1600x1200x32 w/ 2X FSAA on the ATI card.
102fps / 44fps
So I figure I gained about 10-15% performance by reformatting and
re-installing Windows on a fresh install, so there probably was some left
over driver instances causing the slowdowns.
At 2X FSAA 1600x1200x32, I doubled my framerates in D3D with ATI over the
OpenGL with NVidia when alone on the track. I gained about 25-30% frame
rate at the slowest points for both cards. As the resolutions come down, or
as the FSAA is turned off, the difference isn't that great. Of course, your
mileage may vary...
Time to do some more testing so I can decide if the upgrade is worth it.
Installing GTR2002 again now...
