Thanks, I hadn't yet realized about the appending.

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.
