Re: Mass Effect 1 Legendary Using Integrated Graphics by DEFAULT? WHY??!
I understand that this is frustrating, but I fail to see how this is Bioware's fault.
If your system is not recognising the MELE ME1 as a high performance 3D task then there is a problem within your system.
The "Mass Effect Legendary.exe" you speak of is presumably the "MassEffectLauncher.exe" and that is not the game but the launcher.
To make the NVIDIA control panel recognising the game exe you must point it to the individual game executables under ">drive<:\Program Files (x86)\Origin Games\Mass Effect Legendary Edition\Game\ME1\Binaries\Win64" respectively "...ME2\Binaries\Win64", ...ME3\Binaries\Win64" should you get the problem there to.
