Ok found, its unaligned access, which just tolerated on x1000, while x5000 and sam kernels know to be restrict to unaligned accesses of all sort. I.e. bug in code of demo, just by luck/unluck x1000's kernel tolerate it. So those who have crashes, try plz this binary instead of original one, and if all will be ok, will replace archive on os4depot:



I tested it—it's really great in terms of color—averaging 100 fps and never dropping below 60 fps in windowed mode......and yes, the demo is definitely worth playing on the Amiga. Thanks yeahhhhooooooo

Unaligned_fix version, right ?

@All
Found why it fail on SAM460 : missing GART :( Beta version with GART works fine. That can be fixed in 3 ways : in MESA, so to have the same fix i apply for the RadeonHD 3.7 which not have GART, by making SAM460 patch, or by add workarounds to demo.

I tested it right away with the fixed version because I'm familiar with the problem you described and have seen it often in crash logs. It would definitely crash on my system as well.

IMHO: if GART is "fixed" in those beta RadeonRX/HD drivers, then maybe wait until they are availabe to the public. Hopping doesn't take too much time.

I hope you not for real :) radeonrx driver with gart for sam boards were done about 2 years ago by Hans, but its AEON-Mattew, so forget about. There other solutions already, soon there will be some more info.

I thought it was about a year ago?
i also read it doesn't actually do much for performance on the sam460.
Although I suppose if it helps things to actually work, that would be a help.

The latest Enhancer pack with presumably that updated driver was due out before last Xmas as announced by Trevor at AmiWest.

2.23 wasn't real latest beta, there were some others after.

Time fly.. Just checked, it was Marth 2025 for beta version with GART enabled for SAM => 1.5 year ago.

It didn't improve situation much, that true , just in some areas. For example some Irrlicht engine examples jumps a bit (like from 20 fps to 25). Or like Cow3D test case. But then Spencer didn't changes at all. Other things where CPU much involved also didn't help. But still, it better, even a bit faster, and, things which need gart works at least.

Hoping it will be ever released after it wasn't for so long mean (for me at least) it will be never released, or, when no one will need it. At least, i didn't hope from anything from AEON-Mattew anymore. Other ones may want to wait some years of course :)

If someday they will release something, good, if not - we will have soon necessary replacements/fixes/whatever.

@All
Can any of you who have SAM boards and RadeonRX 2.12, tell me what size of the file you have ? (i need that to know if all of us have the same exactly binary). Thanks a bunch !

Thanks!

I reuploaded ChaosTheory with alignment fix on os4depot (in upload query for now), and those who want it to check on Sam460 boards, check this out : https://www.amigans.net/modules/newbb/viewtopic.php?topic_id=10177

Defo worth the wait, really nice demo.
Really appreciate the effort it took to get this running on a Sam460.

Cheers
