As Eike already mentioned opengl32sw.dll is only used as a last fallback, so this migh explain the difference too. Bad enough, I had hopes the software renderer really works across all graphics drivers :(

(It doesn't crash for me btw with a stock Windows XP in VirtualBox).

Huh? I don't think we've changed anything in this regard, we've been installing vcredist for MSVC2010 previously, now vcredist for MSVC2013 ...

Thanks a lot for the testing :)

Not really a feature, just factoring out stuff in a separate dll AFAIK.
