DirectDraw apps slower in Windows 2000?

Recommended Posts

I've been using Snes9x,among other windows based emulators (WGens, Dgen, System 16 emulator directx ver. ...) (with free roms, not illegal ones :-) ), and I've found out they perform awfully in windows 2000. In Fullscreen mode, I get same FPS than in windows 98. But screen looks blocky (in windows 98 there is a kind of iamge interpolation with softens image blocks, and it's not FSAA)-

 

In windowed mode, snes9x runs fine, unless I try to resize snes9x window. After that, performance drops a lot, and from 40 FPS i get 18 FPS.

 

I've read in sys16emu file that riva tnt cards use a special feature, called "glint", which allows window-resizing without perfomance-loss.

 

Since I'm using the same generic drivers (5.30) in both OS, I would like to know wether it is a specific windows 2000 issue, a directx 7, or my card. Does SP1 fix that?0

 

My specs:

-Asus p5a (bios 1010 beta 002)

-128 MB ram

-riva tnt 16 MB

-HD 6,4 GB

-Windows 2000 pro (5.0.2195)

(Due to stability issues, k6 write allocate and EXTERNAL CACHE are disabled in my bios)
