Re: GL_ARB_transpose_matrix redux?

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,
