Will be interesting to see what results You get when moving up to PCI cards in this series.
I just got 31.5 FPS in Doom with Intel dx2-66, S3 trio 64 2MB, 64MB edo ram. Sound on.

My first PC was a VLB (Cirrus 5428 1MB) equipped 486 with Intel dx2-66 and this is noticeably faster than I remember that being.

Yeah, you generally don't see DX2-66s getting faster than the high 20s in Doom. My DX2-66 with VLB CL-GD5428 gets a little over 24 with default BIOS timings, and a little over 27 with all BIOS timings maxed out.

I just checked Phil's VGA database. There are 29 DX2-66 results (14 AMD, 15 Intel) and the top-2 are 29.3 (Intel/S3 Trio64 VLB) and 28.5 (AMD/S3 Trio+ PCI). Out of the top-10 results, five use VLB, five PCI. The graphics chips are:
1. S3 Trio64 VLB
2. S3 Trio64 V+ PCI
3. MGA2064W PCI
4. S3 Trio64 V+ PCI
5. S3 Virge 3D/DX PCI
6. Tseng ET4000/W32p VLB
7. CL-GD5428 VLB
8. CL-GD5428 integrated VLB
9. Tseng ET4000AX VLB
10. Tseng ET6000 PCI

You should add your results, you're definitely in good company. 😀

Interesting to see the faster cards clocking in at around 25fps in Doom. Many years ago I was shocked that an old 486/66 + VLB, which was a gift from a friend, was running Doom I at only 27.xx fps. I think I was fiddling around with the bios and a second gfx for hours on end, because I had the presumption that a fast/er 486 would at least push a fps count in the low 30ies.
Well, that settles it I guess.
I often wonder if at least one of the 486s which were used during Doom's devlopment do still exist... that would be a juicy vintage steak.

Very hard to compare with other systems unless everything is identical. The 486's performance vary greatly between chipsets, motherboards, BIOS settings and most importantly memory timings.

I spent alot of time trying to find a PCI Pentium system that matched my Pentium Overdrive Socket3 VLB system. I used several different benchmarks and used different hardware and BIOS settings to match the results as good as it could be done.
