- This is true. worse, the repaint appears to be character-by-character from
- the bottom of the window, upward -- unsightly and slow.

-
- While the lower-end of the 386 family cannot be realistically compared
- with a SPARC, with or without GFX, the implementation could be faster.
- In all probability, they will be, too. We'll just have to wait.
-
- IBM didn't write these drivers to provide speed, they wrote them to
- work. They've also written them for generality (to various ET4000-
- based SVGA implementations). I heard in this forum that these drivers
- are to be provided to 3rd party vendors as models of how to write
- video drivers for OS/2.
-
- Diamond's (Binar-written, WinSpeed-based, Diamond-modified) Turbo
- Windows Drivers for the SpeedStar provide an astonishing performance
- improvement over the standard Tseng drivers for Windows. If Diamond
- applies the same lessons to the box-stock ET4000 drivers for OS/2,
- SpeedStar users, at least, can look forward to better performance...
- eventually.
-
- >On my 486, with ET4000, the DOS window scrolling is pretty quick.
-
- When I can afford to throw horsepower at it, I will. Still, I want
- and expect fast drivers to use with my increased horsepower, as well.
- Since Binar and Diamond have shown us something of what is possible
- with SVGA in general and SpeedStar in particular, I have some idea
- what is possible and how much we can expect. Time will tell, though,
- and we're going to have to let it do exactly that.
