Bad graphics/video performance




after managing to install stage3 MATE variant and enabling gfxcard-intel mix-in (for Mobile GME965/GLE960 Integrated Graphics Controller, in particular a GLE960) + updating the entire system, i still get bad video performance on players like vlc (stuttering and high cpu usage). The high cpu usage, bad video quality and stuttering is a clear indication that there is very likely no hw acceleration involved or wrong/missing codecs. Any ideas what to fix or look at to find the cause? I had a live NomadBSD usb pen at hand and checked just for testing purposes the video output and quality there. Hw acceleration works out of the box and video quality was excellent, no stutter, no (too) high cpu usage.

Progress report: Disabling the MATE Software Compositor (System->Prefrences->Look and Feel->Windows) made stuff like VLC playing smooth, but started graphics tearing. No solution at all, but info maybe helps others somehow (or watching videos temporarily stutter free 😂 ).
