So here is the thing, I'm tryinv to play Quake 1 in pure dos in 640x480. On a laptop with Pentium 266mhz MMX. I'm getting 10 fps:

Maybe that what i should have, or there is a chance i can have better performance? I've tried utilities like fastvid, but looks like they all work on newer CPU's. Performance in pure dos and in windows is the same.

I don't remember ever testing a Pentium at 640 x 480 in Quake/software mode, but I'm pretty sure that 10 FPS is pretty much what you can reasonably hope for with such a CPU. 😀

EDIT: According to Tom's Hardware, apparently it should be ~ 15 FPS.

what do you get in 320x200 or 320x240

a 266mhz Pentium shouldn't be the throttle here

This is normal.

All that I can possibly suggest that could improve it is using S3VBE, but don't expect miracles (like P6 optimization).

That's normal performance for a Pentium MMX at 640x480 using software rendering. There's a reason people were using Voodoo cards back in the day. Take a look at my benchmarks with and without the Voodoo.

If you want to play Quake 1 at 640x480 using software rendering with 30+ FPS, you need at least a Pentium II 400 and a graphics card which works with FASTVID. However, if you want 60+ FPS you probably need a Pentium 3 at 800 MHz or higher.

In 320x200 or 320x240 i'm getting good fps. But it's low resolution 😀

By the way, I've got a question. In pure dos I don't have anything higher then 3**x2** resolution. I need to run UniVBE and then i'll all of them. But! With UniVBE i've got garbage in 320x240. You can see it here:

No idea what this all means.

I'll check S3VBE.

I've been dancing around Voodoo Rush rig lately, and was baffled by the same low fps score on a m/b i'd like to use there.
So far i've tested these configurations with a P1-200MMX, a Rush and a HDD being a constant, m/b and ram getting change.

FSB* MUL Quake1 timedemo 320x200 / 640x480 fps
Biostar M5ATD (ALI Aladdin IV+ 512K burst cache) + 64MB SDR on the fastest timings
66*3=200 49 / ??
83*2.5=207 54.4 / 10.5

Lucky Star 5I-TX2A (i430TX + 512K burst cache) + 64MB SDR on the fastest timings
66*3=200 49.2 / 16.0
75*3=225 55.1 / 17.9
83*2.5=207 54.9 / 18.4

Kaimei KM-V5-VPX (VIA VPX + 256K pipeline cache) + 32MB Simm (default 60ns settings)
66*3=200 44.7 / 15.3 (FPM Simm)

Intel TC430HX (i430HX + 256K pipeline cache) + 32MB Simm
66*3=200 45.1 / 15.5 (FPM Simm)
66*3=200 47.2 / 15.8 (EDO Simm)

I's say 10 fps is a pretty weird score for Aladdin IV+, as otherwise it's not a slouch of a chipset, and as 320x200 score suggests PCI bandtwith is there and CPU delivering just fine. Mebby some hidden PCI timings kicks in, mebby something IRQ related, mebby installing Win will help, idk.
I may test Aladdin V and MVP3 as well, but it may take a while. For these i'd suggest ALI would score low fps as well (just as Super Socket 7 low Quake benchmarks suggests), MVP3 score a tad higher than VPX.

Did the tillamook have software settable multiplier? I’m trying to recall. Maybe it’s not running at 266? Might be gfx limited. Or maybe if you are running dos from windows that may be slowing it down. If you have a usb pcmcia card installed that could slow things down

This is what we had back then... low res or no-FPS. 😁
