App to stress test OpenGL...?

I've recently obtained a 1.25GHz emac. Unfortunately, when I run Apple Service Diagnostics on it(*), it repeatedly fails on the OpenGL rectangle test either by hanging the system or stating 'checksum failure'.

I'm going to be sending it to an Apple repair centre, as the serial number indicates it should be covered under the power/video issue.

However, I'd prefer to replicate it without an Apple provided tool - any suggestions? Free Games, modelling apps, etc?

(*) This is after being burnt by another emac purchase. Now I run the diagnostics straight away to test it out..

emac, Mac OS X (10.4.11)

I used to check video (including OpenGL) performance by downloading free 3D game demos like Unreal Tournament or Quake. You may want to look for older versions as some of the latest are probably designed for a Mac of greater power than the eMac.

Unreal Tournament 2004 Demo runs smoothly on my old PowerBook G4 (OS 10.4.11) 1Ghz with 1G RAM and a 64MB VRAM video circuit. If you can find that one, it should run well if your eMac's video is healthy and working normally. If it fails to run or you get odd screen artifacts, that says something is wrong in the video components.

EDIT: Found a link to UT2004 demo (200MB file):

Sysreqs:
Mac OS X Only
Macintosh G4 or G5 with an 800Mhz or faster processor
• OS X v10.2.8 or higher
• 256MB RAM
• 32MB video card

Thanks, I'll give it a go.

I've found a copy of the Helios screensaver at http://www.reallyslick.com/ - it reliably either freezes the emac completely, or to the point that only the mouse pointer works.

I guess that's probably good enough proof..
