(and then again on the machine i'm using right now, pretty complex examples only show minimal dragging). > I'm not 100% sure it's really vsync, as it did not even help when > manually forcing it to 0 using glXSwapIntervalMESA or glXSwapIntervalSGI, > but right now the packages in testing seem to be unusable for some > people > (http://forum.openscad.org/OpenScad-2014-03-Segmentation-Fault-td14800.html). i'll let you know which results the hopefully more non-debug builds got me when they are through. thanks for bringing this to my attention chrysn -- To use raw power is to make yourself infinitely vulnerable to greater powers. -- Bene Gesserit axiom signature.asc Description: PGP signature
