View Full Version : PD5 OpenGL speed reduced?!?!? Win98

1st July 1999, 13:22
Although the new 5.13 OpenGL drivers appear to be more stable then the the Beta2 release, I immediately noticed a significant performance decrease at 1024x768 16bit when running an OpenGL app. Indeed, testing with WinTune 98 confirmed a rate decrease of approx "9" MPixels/s compared to the ICDBeta2 install.

WinTune 98 OpenGL test, 16bit color depth.

4.51 drivers:
35.x MPixels/s

5.13 drivers:
26.x MPixels/s

System: Pentium II 400mhz
Display: Millennium G200 SDRAM 16mb
