Quake on the older Amigas

Makes sense and is probably the reason why 10/100 ISA network cards were never made.

Wrong.  10/100 ISA netcards have been made by Intel, HP, etc.

VRAM bus speeds. I get deja vu every time this comes up :lol:

[yogisumo]

Oh well. Thanks for the correction. The question now is, why?  The card would, if 4mb/s is correct, saturate the bus...  I know I've never seen any.

I've only experienced the HP cards which used proprietary 10/100VG Ethernet, so it's hard to compare it with modern 10/100 equipment.  But, even on the 386 and 486 machines at the time they were very fast.  I never got a raw transfer speed but you could definately tell the difference between the 10Mb cards.  Just a note that even at 4MB/s that's more than 3 times the speed of a 10Mb card which is "why".

Ok.  That explains why I haven't seen them.  Those would have been pretty expensive systems in their day.  I'm guessing the technology didn't trickle down to the general public.  PCI would have shown up by the time 10/100 became more mainstream...

GLQuake needs 3D hardware to work.  Sorry about taking so long to re-post.

Quake on 680x0 is only really feasable on 68060. It's mostly the calculation overhead that kills it - VRAM speed is a secondary concern that has more impact once you move to PPC / GL.

I have a BPPC 040 25MHz and BVision. Under AGA it managed around 3-4 fps, peaking at 6. On the BVision it also managed about 3-4fps, peaking at 6. In this case the AGA speed / C2P time was not the limiting factor at all. It was already so slow that simply rendering the frames killed it.

To really enjoy (software only) quake on 680x0, use a CSMK3 060 and a graphics card (preferably on as fast a bus as possible). I've seem  almost 20fps on such a setup.

GLQuake2 on 68060 is also rather playable, if you have a supported 3D card. GLQuake1 is actually slower than GLQuake2 largely because GLQuake1 was a hack whereas Quake2 was written from the ground up with GL support in mind.

I thought an 040/25 MHz were faster than an 030/50 MHz. I played this on a 68030@50 MHz wirh 48 MB of Fast mem and I got 2 FPS in the smallest screen size. To play Quake you need a FPU or the game doesn't work.

Play Quake (Clickboom version with 060 patch) on a 68060@50 MHz with 128 MB of Fast RAM, I got 10 FPS in Full Screen, with the open source version 14 FPS. This on AGA resolution 320x256 (PAL).

It is, but Quake will bring both very much to their knees. The 3-4fps was for 50% screensize.

You should play NTSC if possible - 320z200 will give you a bit faster FPS.

On my BPPC, WarpQuake ran nicely at 320x400 (NTSC laced) on AGA, getting about 15-20fps fullscreen.
