Hi Peter, one request: please keep the list cc'd--maybe somebody there knows something.

Any ideas what might be wrong? cutil source is included under common/, there's no GL stuff in there. There's also no explicit GL interop initialization in the SDK--for the runtime API, that's apparently not necessary. Check this here, too: - http://forums.nvidia.com/index.php?showtopic=58779&hl=cuGLInit If you're still not having any luck, I'll try to get some help from Nvidia. Andreas
