Why am I seeing untextured or incorrectly textured triangles in GLQuake or Quake 2?
This is almost certainly due to overheating. The texture processor on a Voodoo 3D card runs very hot to begin with. When the texture processor overheats, it will start to drop textures exposing bare triangles (everything in a 3D image is made up of triangles). Over-clocking will also cause this as it also overheats the texture processor. Overheating is not good for silicon chips and over the long haul will damage them. If you’re overclocking your Voodoo 3D card, throttle it back to the maximum recommended speed, which is usually 57 MHz. Trust me, you don’t need to run it any faster than this. If you continue to have overheating problems, you may need to re-locate the 3D card. Place it in a PCI slot closest to the power supply fan and leave an empty slot, if possible, between it and the next card. Re-route ribbon cables so they don’t obstruct the flow of air across the 3D card. You may want to consider installing an additional cooling fan. You can purchase one of those slot-cards that h
