- I decided to play with my DOS settings this morning and I have sped up my
- DOS scrolling by a factor of 10.
-
- I have a Tseng Labs ET4000 Mega/Eva 2 and decided to turn off the
- VIDEO_ROM_EMULATION. Seems the ET4000 is a lot better at scrolling than
- OS/2.
-
- Now, if only I could do the same for OS/2 sessions. My OS/2 windows are now
- 10 times slower than my DOS windows at text scrolling (I have timed them).
-
- I find that a little ridiculous to be honest. We have all these fancy
- settings for DOS sessions but are at the total mercy of the OS/Video
- Drivers/Sun Spots when it comes to OS/2 sessions. Is there any way to make
- OS/2 not use software for scrolling and go to the Video Bios. 40 Seconds to
- scroll 128 lines in a window compared to 0.78 seconds full screen (and now
- 4 seconds in a DOS window) is totally pathetic.
