So Mass Effect is now runnning on my Win7 x64 AMD-Grafic Card
to get it running ive done th following things
1. Install Patch 1.02
You can download patch 1.02 here: http://masseffect.bioware.com/me1/pc/updates/index.html
If the Pacher Says "Mass Effect is not found." dont worry. Coppy the Patch to the game folder (or the Binary folder)
(You can check your ME version with the ME-Configurator in your Binary folder)
2. Check your PhysX Driver. the Legay-Version is needed.
You can download the NVIDIA PhysX Legacy System Software here: http://www.nvidia.com/object/physx-9.12.1031-legacy-driver.html
(If you need a PhysX for Mass Effect 2 the one above will do)
3. Run Mass Effect as Administrator
4. checked you have DirectX 9 also installed
You can download DirectX 9.0c End-User Runtime here: http://www.microsoft.com/de-de/download/details.aspx?id=34429
