Vendetta needs 24bit colour depth. I got the same message, but nvidia have (at last!) added OpenGL support for 24bit depth to their drivers. Upgrade to the newest one and edit your XF86Config. It worked for me (same as doom3, btw).

uh ... huh? That's new to me.

I've been playing the game in 16bit mode on an nvidia card for a long time.

Oh? Well, maybe I'm wrong, but it worked for me. I had the same error, did this (because it helped with doom3) and then it worked.

what?
I've had 24bit support in the nvidia drivers "forever"...

With GLX?
