Crazy System Slowdown on Linux When no Camera in Scene #62

Open randomPoison opened 10 years ago

randomPoison commented 10 years ago

If no camera is put in the scene when the window is displayed, the window shows garbage and causes the entire system to slow down. This only happens on linux (Ubuntu 14.4), on Windows screen is simply black and there is no noticeable impact on performance.

Most likely this is an issue with Ogre, so we should probably ask around on the Ogre forums and see if anyone has experienced something similar and if there is a fix.

Even after upgrading to Ogre 2.0 this still occurs.

It's possible that this is happening because the main loop runs too fast (since no rendering occurs) and winds up eating up all the cpu's time. It would be worthwhile attempting to put a cap on the framerate and seeing if that fixes the problem.
