Of course, my own Big Project isn't done yet, in part because I decided to retest the GeForce FX with NVIDIA's new 43.45 drivers. When I was trying to decide whether or not to retest, I asked NVIDIA to explain what's new in 43.45. Here's the answer I got:
DirectX 9 compliance for GeForce FX 5200, 5600 and 5800 models and for all Quadro FX models.I was looking for something a little more specific, but you get the idea. In my experience, 43.45 is just a little bit faster (1-3 fps generally) than the previous 43.00 drivers that card makers like BFG Tech and PNY made available for download. The 43.45 drivers don't include any major changes to controversial things like the FX's various ansiotropic filtering modes, so performance isn't altered much there. I did notice some notable performance gains in DirectX 8 pixel shader execution on the FX, though.
DirectX 9 compatibility for legacy NVIDIA GPUs, including GeForce 2, GeForce 3 and GeForce 4.
Numerous performance optimizations.
A few bug fixes.
