Bit of a long shot this...

I get an Access Violation seemingly in the 18th call to immediate 
glTexCoord2f after resizing the window with SDL_SetVideoMode()

There is no usable stack trace for this

It only seems to happen with this card so far. I reload all the OpenGL 
assets as usually they are discarded on windows.

I've had problems in past C apps with resizing via SDL_SetVideoMode. 
IIRC, what I did then instead of resizing was to call SDL_Quit and then 
reinitialize everything with the new video mode settings.

If that doesn't work, you might also try manually unloading and 
reloading the shared libraries:

DerelictGL.unload();
DerelictSDL.unload();

DerelictSDL.load();
DerelictGL.load();

// reinitialize
...

Aha, thanks for that. I might give that a go at some point. Is the SDL 
broken or is it the video driver?
