This is not only a Intel / nVidia issue... it happens on my friends Dell Computer and he's got an Intel/AMD combo on his one and he get issues when playing like :
- Warning about being low in memory.
- After a few alerts, a BSOD.
Note that we tried all your solution and seems to be related to Windows 8.1 + Intel + AMD. Three month and nobody found a clue about what happening there. Hopefully, mine with a 3D screen, don't have this issue, as long as the 3D screen make the HD graphic acceleration being deativated...
This is definately related to Intel HD Drivers. Not AMD, nVidia or the games by themselve.
Note a few games are not able to use the GPU because they don't see it.
Anyway, hope we'll have a fix... a day in the future !
