- UniVBE supports more video cards than svgalib, so you may be getting a
- linear frame buffer under DOS and not under svgalib. If you have a
- linear frame buffer on both, they should be about the same speed
- (although actually the svgalib port uses hardware accelerated rect
- fills, something the DOS port won't be able to do until UniVBE 5.2
- comes out).
-
- One way you can tell if you have a linear frame buffer under svgalib
- is to start executor in 8bpp mode and bring up the alt-shift-5 panel.
- If your only choice is 8bpp, then you've got a linear frame buffer.
- This is caused by an svgalib limitation; if you've got a linear frame
- buffer, you can get other modes and take a performance hit if you
- start Executor in something other than 8bpp.
