I'm trying to run Tesla Effect on Windows 8 with a Radeon graphics card. But the video always shows like in the attached image. I have change every setting I think I can find but nothing sorts this out. Has anyone got any ideas. If you can't see my image, the video in the gameplay is limited to the leftmost 25% of the screen and is stretched really long, with the other 75% of the screen block green. On static bits everything is fine.
Thanks for any help
Aaaannnd I just solved it! A different menu allowed me to run this specific application in high quality. Doh! not sure why it affected it like that though.

Thanks Cubase. In my case a graphics card setting was all that needed to be changed. A really useful link you provided however.
