The Radius Thunder-IV drivers include a QuickDraw accelerator extension that speeds up Quickdraw noticeably. There is a hot-key you can hold down to turn it off and on again. I did it on a IIci with a 040/50 in and it made one HECK of a difference to the speed of screen redraws on the desktop. It made 7.x very usable at 1280x1024 [

Actually, although scrticly OT, the video on the 840av is blooming stonkingly quick too, so much so that despite the restricted resolutions (if you want to keep the video overlay working at 24-bit) it was preferable to the Thunder IV (hence why I dropped it in the IIci [
