Doom Frame rates on various systems?

[gimbal]

cool Not rocket science then, just a period-based assumption.

I’m a bit disappointed with this Doomattack result on my TF1230. I thought it might at least be double figures.

Is that 5 FPS?

It is indeed

Holy... my condolences

Well, Rolling Thunder isn't much faster.

The PS1 version of Doom maxes out at 30fps.

It maxes out at 35fps (never dips below) on my A1200 with Vampire V1200 V2 accelerator when running at 320x240, and I get about 17fps when running at 640x480.

I get about 70 fps at 640x480 with ADoom on one of my A4000s. Or 59 fps at 640x480 with PrBoom with a bunch of fancy effects on it.

What is in that A4000?

[gimbal]

Yeah its so easy so say "my A4000" but that sounds like an A4000++++

Something in the realm of

[grelbfarlk]

It's an A4000D with a Mediator and a Ragnarok with an MC68950 and XAGA RTG card, CSPPC, FM801, Spider USB, and a 10MB NIC, Ratte Switch, nothing special.

Doom running under Dosbox on the same machine gets 20FPS with sound and music at 320x240.

Like the card Hedeon linked to.

I get 35fps in Doom Attack at 320x200 on my A600. It seems to be frame rate limited though as it sticks to exactly 35fps and doesn't go any faster with a smaller window. In 640x400 it does 25-30fps.

In this video a 486DX2-66 with VL bus VGA card got 26.4fps. A 486DX-33 with ET4000 ISA bus VGA card got 12.8fps. A 386DX-40 with 128k cache and ISA bus overclocked to 13.3MHz with the same card got 8.5fps, and a 386SX-25 got 2.7fps.

On an A1200, long ago (judging by the reflection on the monitor this was at least 11 years ago, likely longer)

The screen wipe effect is slow due to reading back from the VRAM but the in game frame rate was typically in the 20-30fp s range at 640*400.

When Doom came out I still had my 25mhz 486 from 1992 to play it on, my friend had an AMD 386DX40. We both had ISA, my SVGA card was some bargain bucket OAK chipset thingy.

With this setup I would at least get the magical 25fps sort of speeds with the game window just 1 step below maximum size in 320x240 pretty much all the time. My friend's 386 managed roughly 2/3 of the framerate. I can't remember if this was when my friend had found a cheap VESA Local Bus 386 motherboard though or if this was using his ISA motherboard from 1992.

The graphics card does not matter for DOS Doom, it is all CPU. Your friend's computer must have been magic, I played it on an Intel DX40 as well at the time and it only became marginally playable in the low resolution mode and in a reduced screen size.

The type of graphics card matters quite a bit. You can check post #17 for FPS numbers.

Well it mattered on arcade emulators because playing Galaxian on my Pentium PC with that old ISA card from my 486 gave half the framerate compared to using the PCI card it came with (was testing it before selling it to a friend). I was just mentioning it just in case it did have an impact because I do remember my friend getting a VLB 386 motherboard from a computer fair for £10 around that time. Doom is really a game from the PCI era not the ISA era of home PCs IMO.

I should also point out I had no soundcard in my 486 so I don't know if that affected the framerate having zero sound. My 486 was just for coding for my degree course at university and I spent the budget on CPU not soundcards.

Some Oak cards were better than others. In this test of Quake in 320x240 on an Athlon XP2200+, an OTI 037C only got 9.2fps, slightly ahead of a Trident 8800 at 8.7fps and behind a Trident 8900B at 11.5fps. However an OTI 067 got 21fps, and an OTI 077 got 26.8fps. The fastest ISA cards (surprisingly including a Trident 8900CL) got 36fps.

I don't know how fast my 25MHz 486SX was, only that it played Doom very smoothly so I'm guessing it was around 20-25fps.

My friend's 386 managed roughly 2/3 of the framerate. I can't remember if this was when my friend had found a cheap VESA Local Bus 386 motherboard though or if this was using his ISA motherboard from 1992.

Certainly would not be with an ISA bus card.

Based on the youtube vids posted in this thread of Doom playing on 486 class machines, I think that is more of that rose colored glasses specs. (I'm guilty of that myself. More than a few times I go back to see a game I loved and it runs slower than I remember.)

A 486DX33 with a fast VLB card would be around 15/16 FPS... and an SX25 slower still... (The SX/DX shouldn't matter much, as apparently Doom didn't use an FPU; I didn't know that when I started checking...)
As mentioned above, the vid in post 17 has a great chart (@ 15:27 timecode) on actual 486 Doom perf tests...
