There has been some debate a while ago about sfft's driver performance in widnows 2d.
People reported having slugish desktop and not so good video playback, so i decided to give a 2D benchmark, Blt Test (http://www.stereopsis.com/blttest/) a try.
Unfortunately I have my Voodoo3 on a crapy mobo right now, that has crippled memory throughput

First, resaults with SFFT 1.4


With Amigasport 3.0 ...


...and with windowz xp default driver

1st winows default wins by a little but consistent margin
2nd SFFT
3rd Amigasport

Tests were done in 1024x768, 32bit, WinXP, Cely900, Abit VA6 m/b
If anyone can confirm these resaults, or point another 2D benchmark, be my guest.
Untill then, SFFT is good for Voodoo3 at 2D also (can be improoved tho)
