I recently added multiple render targets to my engine, i also use 16x multisampling. Everything works fine until i quit and try to restart the app. If i enable multisampling i get a opengl error dialogue box that says:
Your hardware configuration does not meet the minimum specifications needed to run the application. The application must close.
please visit etc…
Eventhough it worked fine on the first run. At this point if i restart my pc i can get it working again, until i quit and try to run it again. So i’m guessing that by restarting my pc i’m clearing out the video ram or anything else that still might be resident so the cause of the issue is improper resource cleanup. Ii’ve made sure i deleted all my textures, framebuffers, vbos, vaos etc etc. And whouldn’t the driver clean up any leftovers when the glcontext is destroyed anyways?
All my buffers reports that they are complete and without errors.
Another note of interest is that i only get this error when i render to more than one buffer at once using gldrawbuffers and if i use 16x msaa, if i use 8x msaa or lower or just render to one target there are no errors.
