Thanks, I hadn't yet realized about the appending.
The whole series was actually with the same drivers. And while it sounds crazy, I *think* that I somehow once got the thing to run a couple of demos once. Maybe this card has some capability (say, stencil buffering) that matches the demands of some scenes but not others?

No, we always request the same capabilities. In an entirely unrelated set of experiments however I have found that memory requirements can play a relevant role, e.g., if you load sizable other libraries before starting Croquet it will fall back to the software renderer. I can only guess that what happens is that opengl32.dll fails to load the ICD which ultimately provides the accelerated driver. I'll send you (off-list) a VM that fixed the problem for me (by reducing the default max. virtual memory size from 1GB to 512MB). Let me know if it works for you - if it does, I'll change the default generally. Cheers, - Andreas |
