Is that "japanese I don't know"/"2 followed by japanese"/"4 followed by japanese" drop down menu anti-aliasing? Strangely, on my AIW 8500 128MB, there is no change in performance (about 2852) with Hardware T&L with any of those sliders, though it does look anti-aliased. And Pure Hardware T&L is a hair slower (what does that mean, anyways? prevents drivers from offloading some work on to CPU for T&L tasks?) than just "Hardware T&L".
Also, CPU speed seems to matter not much at all, since I get close to the same score (21xx I think) as Nappe1, but I have a 1.377 GHz TBird (maybe it is the FSB), with software T&L.
All these tests were with many browser windows, an application, and the full host of my sys tray icon bloat running on Win ME.
EDIT: Laf, I had just switched Direct3D to permanent Antialiasing for Morrowind since I don't trust my tweaker for per-game settings until the next update...that might explain why my results were identical. I'll go back and see how it runs with that turned off. I'd say wake up and go back, but I'm in a permanent fog today, it feels like. :-/
EDIT2: I wasn't mistaken the first time, even with it clearly visible that AA is not enabled, it sticks at the same speed. I do have vsync on, but it is not locked at 30 Hz (It is 120 for that resolution). I also note that Software T&L behaves oddly, with it actually being slower instead of just "jerkier", if you follow. I also just tried VSync turned off. Weird benchmark...
