This is a big issue for me.
I've recently installed a game that makes use of OpenGL.dll for dynamic lighting yet the game seems to only render in D3D mode.
The game is Cry of Fear - a recent mod but for the original Half-Life 1 engine.
The game is only supported in OpenGL mode. When I run it in OpenGL mode, although the game "believes" it's rendering in OpenGL mode, it is missing some of the dynamic lighting which is called from then OpenGL.dll file
This is apparently a clear way to see if your game is running in D3D or OpenGL mode.
Additionally some hue effects appear when you're in D3D mode instead of OpenGL mode and I see those too - so everything points to it rendering in D3D dispite me changing the settings to OpenGL - no one running the game in Windows XP/7 is having this issue so I suspect it's something to do with the virtual drive? I've tried different versions of wine 1.3~ 1.4~ 1.5~ and tried running it in Windows XP/7 mode but there has been no change.
If anyone knows a way to perhaps "force" rendering in OpenGL mode I'd love to know it!
