What you're describing is what most games have been doing traditionally. Croteam's research shows that this results in micro-stuttering, because frames may be presented too early. To avoid that, they want to explicitly time each presentation as described by Christian. Maybe we should try getting the Croteam guys researching this involved directly here. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ amd-gfx mailing list firstname.lastname@example.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
