- What drivers are you all using? Is that problem only with 800x600 and 1024x
- 768 resolution or do you have it with VGA as well ???
-
- On my system (33MHz 386 with _ET3000_ VGA) text scrolling in DOS windows
- IS FASTER than in full screen DOS 5.0 booted without OS/2.
-
- While printing 1000 lines of text from Turbo Pascal takes 12s under plain
- DOS 5.0 it only takes 7s in a OS/2 DOS window with the 14x8 pixel font.
- The timing was done by hand and by the benchmark program.
-
- Having not used SVGA drivers with OS/2 and given the fact that someone stated
- his SPARC being 200x faster on scrolling 1000 lines in about 1s than his ET4000
- should I now expect a ET4000 with the new drivers beeing 30x slower than my
- ET3000 ??? Or are you perhaps doing funny things with your DOS settings ???
