I am playing around with conditional render a bit. I noticed, that everytime i pass GL_QUERY_BY_REGION_WAIT_NV to glBeginConditionalRenderNV my application will crash pretty soon in the driver. I don’t actually need this feature, i only wanted to use it to see whether my app slows down considerably in this mode, to check whether i need to do the occlusion queries earlier.
This is with a Geforce 9600 on Windows Vista SP1 (32 Bit) with driver version 178.24.
Anyone else got the same issues?
