If you go the Tseng route, I would avoid W32 and go for either W32i or even W32p. To the best of my knowledge, W32 does not to memory interleaving when 2mb is installed, and is therefore slower. Also, I believe W32 was buggier when running accelerated graphics in windows.
I normally use Grand Theft Auto in 320x200 and 640x480, as well as Magic Carpet 2 to test out the speed of my graphics adapters in DOS. I don't know how good these games represent overall performance, but I have found ET4000W32p to be quite a bit faster than any of the other cards I tested.
In theory ARK1000 should be slightly faster than Tseng when 0WS is enabled, but I have not been able to get it working in that configuration on my current motherboard. I tried 3 different ARK1000 cards with the same result. I found in the 1WS setting it performed similarly to my other cards.
I do not recall that there was a major difference in speed between S3 764, S3 968, Mach64 VRAM and Mach64 DRAM in DOS. Though it's been a while, and maybe I should run some more benchmarks.
I have not yet had much of a chance to try cirrus logic based VLB cards. I have heard that 5429, 5434/36 are all fairly averager performers.
The slowest card I have tested so far is probably the Trident 9440.
While I haven't found S3 to be the absolute fastest for VLB cards, it is said that they have better compatibility. That might be worth something to you.
