- I just upgraded to a Diamond Speedstar 24X video card and thought I'd
- share a few things I've noticed...
-
- My system: 386-33 clone with Mitsubishi FL6615K 16" Monitor. The monitor
- can do up to 1280x1024 Non-interlaced at 60Hz.
-
- The card has 1Meg DRAM on board and a Western Digital GUI accelerator.
- Up to 24-bit color at 640x480, up to 15-bit color at 800x600, 8-bit color
- at 1027x768.
-
- 1. The card can do 1027x768 at 72Hz non-interlaced which is very nice
- compared to my old Orchid ProII at 60Hz. 1280x1024 is possible with
- this card, but only 16 colors and only interlaced.
-
- 2. There appears to be a problem in 800x600 16-color mode: I start up Win3.1
- and all is fine - 72Hz refresh rate. However, if I run a DOS 640x480
- graphics application full screen, when I exit the DOS app the screen is
- flickering - I guess the card has switched to interlaced mode for some
- reason. This never happened with my old ProII! This problem occurs even
- if I use the generic SVGA 800x600 driver supplied by Microsoft. Diamond's
- 800x600 256-color driver does not have this problem.
-
- 3. The 1024x768 16-color driver comes up with no mouse cursor (for me at
- least). I haven't found this problem with the other drivers.
-
- 4. You must still run DOS VGA graphics apps full screen using Diamond
- drivers. The generic MS SVGA 800x600 16-color driver can run these apps in a
- window. (But I can't use the generic
-
- 5. Some text scrolling (system font) scores from Winbench 2.5:
- Driver chars/sec
-
- MS Generic 800x600x16 41040
- Diamond 800x600x16 58333
- Diamond 800x600x256 18810
- Diamond 1024x768x256 7171
-
- 6. Overall I like it, but there are a few areas which need improvement...
-
- Comments, possible solutions to problems happily requested.
