Hi flakmonkey,

setting up a profile was one of the first things I did. Usually this works well, however not in this case, even with the same driver version as you have.

BUT:

Instead of finding a direct solution, I have at least found the problem's cause - by accident, so to speak. Some days ago I installed GTR2 again, a racing simulation, and all worked well - game was recognised even without setting up a profile first. Then I copied some files into the game directory to use the modified d3d9.dll of ENBseries (to improve visual quality and effects).
After starting GTR2 with this modified d3d9.dll it wasn't recognised by Nvidia Optimus anymore and the Intel HD Graphics were used instead. Without this dll, everything was fine again.

This made me think, and therefore I checked in SH3 again and found out that for some odd reason, JSGME had not deleted the d3d9.dll from my MaGui Widescreen mod properly from the game folder. A manual delete solved the problem, but at the same time left me with the usual 4:3 ratio instead of 16:9.

For SH3 this basically means that every mod that adds widescreen capability and/or resolutions differing from the programme's native resolution will cause Nvidia Optimus to select the Intel GPU. This probably happens because Optimus fails to read the DirectX-Version from the d3d9.dll correctly and therefore does not include the Nvidia GPU. At least that is what I'm guessing from the driver's behaviour.

So, the solution will probably be to wait for the new 29x drivers, hoping that Nvidia might have caught up on that problem...
