What the OP actually meant is that DOS Glide games using the external GLIDE2X.OVL file ran ok within Windows 95 but they fail in a proper DOS environment. Usually an issue with the latest Voodoo Graphics drivers. The solution for this situation is to get the Glide 2.43 runtime libraries (GRTVGR.EXE) …

Am I going to get better compatibility for older DOS games, if I make a system built around a Pentium 75MHz, RAM 2x8MB, S3 Virge, ESS1869? Unless you want simplicity or don't want to mess with utilities, no. The Pentium 75 CPU will give you slower performance overall and the stock FSB speed that it …

I haven't seen a patched version of the Voodoo2's GLIDE2X.OVL file. 🙁 If anything, you can try my my modded DOS Glide 2.4x files for the Voodoo2. YMMV on that CPU though.

As bloodem said, it is a known problem. Depending on the platform, slowing down the CPU (setting the FSB to 66 MHz, reducing the multiplier, .etc) and applying the essential environment variables would help. This is because the original 3dfx version of Tomb Raider (TOMB3DFX) uses Glide 2.1.1 which …

Asus P2B rev. 1.12 does not support FSB 50 MHz. 66, 100 and 133 using Rayer SMB work perfectly. Revision 1.12 of the ASUS P2B has the ICS9248-39 PLL clock generator chip like my P2-99.

In DOS applications supporting WSS, the sound quality is superior to the SBPro mode on most clones. Within Windows, it is relevant as drivers for these clones tend to really use WSS outside of DOS applications. PCI sound cards in my experience have support for the AC'97 standard instead of WSS.

But I'm surprised the Riva TNT isn't supported by Univbe. Maybe use a newer Univbe version? Only UniVBE 6.7 has official support for the RIVA TNT, gains from it are 15bpp and some low resolution VESA video modes. However, 6.7 is the worst version overall as the quality of the utility decreased. I'm …

Official Glide libraries actually automatically enable write-combining on the framebuffer with Intel CPUs to provide speed-up in some scenarios. On the Voodoo2, it sets 8 MB from the physical memory address of the card to WC, then the first 4 KB of that address is set to uncacheable for stability …

I know that the SB16 doesn't use hardware for mixing samples. I'm point out that using software mixing for the GUS is suboptimal. No more suboptimal than what it is for SB16. The game uses the same mixing code in both cases. GUS requires samples to be stored into its RAM prior playing them, making …

OP has a Socket 7 build, so games that do 16-bit Sound Blaster would be period accurate. The GUS doesn't do 16-bit Sound Blaster, and even it's 8-bit Sound Blaster is better handled by a separate dedicated card. Practically any game that supports SB16 will also support GUS for digital audio. …
