At the blender institute we had the same problems and it seemed to be because of the processor (core2's were ok but i7's had performance problems), rather then rebuilding you can set the OMP_NUM_THREADS environment variable to 1. We could make blender detect this on startup and set OMP threads to 1 based on the processor - using a shell script or perhaps it can be done in blender's main function on startup. -- - Campbell _______________________________________________ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
