I'm not sure when this started, but with the most recent version of GZDoom, whenever I restart using the OpenGL renderer, the program show nothing at all, though still works (i can go to exit in the menu and quit normally, though I can't see I'm doing that). After quitting and restarting GZDoom, it has switched back to software renderer. I don't know if this is a problem with my computer or with GZDoom, if there is something in the options somewhere i can change to help fix this. Does anyone know anything about what might be going on?

Have you checked the console output for error messages? You can save it to a file by adding '+logfile log' to the command line.

Well I think that has helped me isolate what the problem is, but I still don't know what it means or how I would fix this. (I'm presuming this is the important part of the log concerning this)

Have you tried updating your videocard drivers?

Wow, thank you, that fixed it. I've had some computer problems recently (bad hard drive. had to get a new one) and thought I had installed the newest video card drivers, but apparently not.
