Poor Flash performance with nVidia GT 8600
this is my first post in this forum.
I'm experiencing really really poor Flash video performance with my nVidia graphic card. When I see a video on some site on internet, the video always has a jerky playback, the only site with an acceptable quality is YouTube. I think it's a driver problem, could please suggest me any "tricky" configuration?
Here's some information:
Graphic card: nVidia GT 8600
Driver version: nVidia 285.05.09 (latest at the moment I'm writing)
OS: Ubuntu 11.10
Hardware: Intel Pentium D 3.00 GHZ (dual core), 32 bit, 3 GB RAM
X Server: xorg version 11.0 with GNOME and Compiz (Ubuntu Unity Desktop)
Options in my xorg.conf file:
Option "PixmapCacheSize" "300000"
Option "OnDemandVBlankInterrupts" "True"
Script that runs on init:
nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1
Browser: Chromium 14.0.835.202
Flash player plugin version: Shockwave Flash 11.0r1 or 10.3r183
I also read in some forum that is useful to put these lines in /etc/adobe/mms.cfg :
OverrideGPUValidation = 1
but I don't have any mms.cfg! So I tried to create it and to put the lines above in it (I also tried one line at time), but nothing changed.
Do you have any suggestions?
Thanks in advice
