GCC version of libmgl.a ?
Yep. No problem following Hedeon instructions about alignment, etc. Some of the minigl demos worked with minor modifications, others need more work.

Just wanted to thank you for your hard work Cowcat.
It is really impressive to play Quake 2 on my Amiga, previously the best I could do on Quake 1 with my 060@80 was 15.7FPS

I have done a few time demo's on my K1 PPC @ 333Mhz using the Sonnet driver and VooDoo3 at 15MB, also using Paula through AHI.

Demo 1 - default settings @ 640x480
28.4FPS
28.5FPS
29.0FPS
28.7FPS

Demo 2 - default settings @ 640x480
19.1FPS
19.6FPS
19.5FPS
19.5FPS

Would using an SB128 help with speed as not having to go back through Zorro3 for Audio? Or doesn't it make much difference?

@kgc210 Missed your post !!

Probably good in terms of speed, but don't know in terms of audio quality. Sonnet gurus know more about that.

Your numbers seem suspiciously low. Make sure VoodooInt=Yes in Envarc:mediator/


Also make sure Sync Every Frame is off in the Q2 Video Menu.



SB128 will not be faster, if it is working properly it will actually be a little bit slower, usually like 1-2 FPS. Keep in mind AHI is all 68k, the fast PCI->PCI speeds are usually an effect of when the PPC is writing to something like Video RAM in a PCI slot. There are cases where a 16-bit audio card can be faster, but usually you're doing that for quality not speed.



Anyway if you want to play with the PCI sound card in Quake 2 there are a couple things you want to change, and I usually forget a couple of these variables.
Ahibits=16 (or 8 if you want to use that for some reason, use whatever you have set in AHI)
sndspeed=22 (set to whatever you have set in AHI)
or it might be s_khz=22
Then there's one more ahispeed perhaps?
