Yeah, my only theory is that the drivers automatically try to guess the GPU to use when it is first started. So maybe just having actual OpenGL object rendered at start would make a difference in the automatic guess?
I can't test it, since I don't have a laptop anymore. But you could just try adding it as a executable commandline argument, and then people can test with it to see if it makes a difference?
For example if you do "-gputest", have the game try to load some OpenGL object in the background of the first menu immediately on start.
