I am testing a VGA VLB S3 Digital Equipment Corporation (DEC) 86C801/805 video card. The image quality seems quite good, and it seems quite fast. It has 1MB of RAM. The BIOS POST screen says this about the card:
Quadtel S3 86C801/805 Enhanced VGA BIOS. Version 2.13.06

Thanks a lot Tetrium, your idea of filming the BIOS POST screen enabled me to write all of that info down! I have installed the Windows 3.x driver for this card (available below as a link), and it includes a DOS utility called refresh.exe. Using it, you can choose which resolution corresponds to which refresh rate. I tried 1280x1024 @ 60Hz, but Windows 3.11 displayed its desktop with a lot of very weird corruption and screen flickering. In fact, all 1280 resolution & colour depths resulted in failure. So, I used 1024x768 instead.
Edit: Added 3) & 4), below.
1) Link to driver software (version 2.41) for Windows 3.x, including DOS refresh.exe utility (80x241.zip from DriverGuide)
2) Link to driver software (version 2.30) for Windows 3.x (S386C805.ZIP from mpoli.fi)
3) Link to version 2.5 of the Windows 3.1 driver
4) Link to the Windows 95 driver
1) & 2) I tested both of these drivers, and they worked in Windows 3.11. I could not get resolutions of 1280 to work. Also, I could not get resolutions of 1024 to work, with a colour depth greater than 256 colours. I am using an 19" LCD monitor.
3) This is the latest version that I can find.
4) This is dated around the same time as the driver on the Windows 95 CD. It probably doesn't make any or much difference which one you use.
I found version 2.41 of the S3 86C801/805 Windows 3.x drivers on DriverGuide. Does any one have a later version, please? Also, does any one have any installation diskette(s) for this particular DEC S3 86C801/805 card please? Thanks a lot.
I'm testing this card on an Asus VL/I-486SV2GX4 revision 2.1 mobo. It has an AMD DX4 120 MHz (write back) CPU in it, with 1 stick of 16MB FPM. I have been using 3DBench version 1.0, Quake, Doom, and WinTune 2.0 for Windows 3.x. For all of these tests, I have run them using the mobo's FSB setting of 50. I can run this mobo+CPU with every setting (both mobo and BIOS) maxed out. I increased the CPU's voltage jumper from 3.3 to 3.6. The WinTune 2.0 benchmarks seem to be good. My very early impression is that this board seems to work very well with the overclocked (50 FSB) AMD DX4 120 MHz write back CPU. I'm quite surprised!
3Dbench 1.0 = reading off the scale! I then ran 3DBench 1.0c and got 97.4
Quake shareware 1.06, fullscreen timedemo demo1 = 13.5
Doom shareware 1.9s, fullscreen timedemo demo3 = 2134/1344
PcpBench, vgamode = 20.8
Wintune 2.0 for windows 3.11
Video speed 😀
Speedsys (fsb also set to 50 for this test)
