leggendo il link da te postato alcuni hanno risolto con i driver della asus invece di quelli amd e disinstallando crome e firefox che usano l'accelerazione hardware e provoca il flickering e tremolio del monitor comunque potrebbe essere come dice il link o problema di bios o di driver.. probabile soluzione sempre dal link da te postato: Unbelievable...guys, i couldn't help myself and started again to search some solution for our problem and thank God (ARES?) i found what the culprit is. One thing is for sure - no more jumping in loading screen, browsers and players which don't use hardware acceleration ( KM, BS...) BTW, i didn't have problem with players like PDVD or Splash which use GPU
So, all you have to do is to open GPU Tweak, switch to advance view and set 2D memory clock from 600 to 1668 then save to ex. profile 1. 3D settings leave on default.Very interesting thing is, when you load gaming profile, 2D settings for memory GO to 1668 but somehow switch back to 600. If you want to use gaming profile, you must also manually set 2D memory clock to 1668 and save to other profile.
However the jumping go away for good, now i'm sure that BIOS is the problem and probably first update will solve this.For now, we must keep GPU Tweak running in taskbar and load profile after restart. I'll try to tweak BIOS and ONLY THIS will be changed and flash card and if it works, GPU Tweak won't be necessary.
About artifacting, flickering - so far i didn't notice problems, but is early to say, ' must try many different games (dx9, 10, 11)
I suppose that you know, most games especially newest one use 3D and 2D combined (during loading screen, cut scenes etc) and of course there is possibility if 2D have problem GPU " going wild "
For now, with this little tweak we have stable screen in loading - Vsync on, off it doesn't matter, browsers, players and desktop.
I recommend you to use D3DOverrider for Vsync because you can force triple buffering for better performance. In application settings, Vsync should be set to " off " when D3DOverrider is running.
I'm getting best results with Catalyst 13.3 beta 3 and latest CAP, driver fusion recommended for clean install
I hope this will work for all of You,
Best regards
