Afternoon

I have done a lot of testing with both the 8800GTS and the 8800GTX (http://www.ttlg.com/forums/showthread.php?t=113501) and as per that thread the problem as far as I can see it is the 8800 card. I have just picked up a HD2900XT and will be testing it for myself and the thief community. I was hopping that the crappy colours (8bit rendering) on the textures/sky wouldnt be present as per nVidia, but alas it suffers from the same affliction to a lesser degree....

Screenshots:-

i855GM, 2900XT, 8800GTX - as you can see the 2900 falls in between the the other two... at least the stars are back...

HD2900XT(PCI-E Slot 1)
# The game stutters badley when you look up and around at the scenary, I have verified this on a few missions including the recent Lord alans Factory...Its actually worse than my cheesy old FX5200 - can you believe that...??!!
# The Catalyst driver refused to install without coming up with the old 'zero display service error' had to do a manual install.
# The fan peridically spins upto 100% even in low 3D resource like thief...
# Tested it with Stalker, the image quality is no better than nvidia, but the 8800 series shows less in-game stutter - this ios comparable to what others have found.
# Looks like Ati have to sort thier drivers out before it catches up with nVidia..

Welcome to the wonderful world of premature drivers.

two differant memory busses (64 bit and 32 bit) mean two differant OS types (X86 and X64 aka 32bit and 64bit), and two differant OSs, each capible of the two differant types, means the driver team has to work on its drivers for four very differant platforms...

Moving on to the radically changed architecture of the 8800s...

yeah, those drivers are gonna get here a little slow.

On the upside, I'm sure Nvidia is looking to hire an extra couple Hard Core programmers.

All in all, there are many things that could be causing the problems.

But I dont understand what you mean when you talk about memory buses. Both 64-bit and 32-bit OS's have a 64-bit memory bus in single channel.
