Hello, people of VOGONS. Some time ago, I found a Pentium 2 computer disassembled on the curb, and I took it home and put it back together. It pretty much worked without a hitch, but with one issue: the 3D acceleration doesn't work right. Almost all 2D accelerations look exactly like they should, but 3D-accelerated things turn into a strobey white mess. I took some pictures in one game as an example (the game is Toy Story 2 Action Game).
Here's the game in software mode. The framerate is obviously unplayably low, but it at least looks like it's supposed to look like.
Now here's the game in hardware mode. The game actually runs at a good framerate and at the right speed, but I don't want to play it like this.
Things I've tried:
- reseating CPU, memory, and graphics card
- installing and reinstalling multiple different versions of the Detonator drivers (versions past 44.03 hang on bootup)
- changing the AGP clock setting in the BIOS
- Memtest86ing and removing questionable memory modules
- installing the updated Vga.drv file from the Windows 98 SE CD (did not fix the hanging issue with Detonator versions past 44.03)
- completely reinstalling Windows 98 from scratch to ensure I have a fresh install of the drivers (did not change a thing)
System specs:
OS: Windows 98 SE
CPU: Pentium 2 w/MMX, 200 MHz
Mobo: W6BXA/V
RAM: 128 MB
Sound: Creative SB16 PCI (CT4740)
Video: NVidia RIVA TNT2 Model 64
VANTA BIOS version: 2.05.13.03
Other notes:
- I use a USB mouse with the machine, and I installed the NUSB version 3 driver to get flash drive support.
- I don't have any other boards from a similar era, and I have no other AGP graphics cards at all.
- I attempted to install Windows XP to see if it was Windows 98's fault. Shortly after completing the install process, the OS crashed after a draw operation failed, and I decided not to mess with it much more after that.
- After removing the questionable modules, I didn't test the remaining one that thouroughly. If that could be the issue, I'll do a longer test.
- When I say "almost all" 2D stuff works, there are a few particular things that do not work right: the icon for the "device not ready" box is in the wrong colors, and the same is for the icon on the box warning me about custom refresh rates in the Windows video settings. Other than that, everything 2D works as it should.
