[Question] Flickering Textures.

[Centimeter]

Config :
Phenom II x6 1090t (defaults (3.2Mhz) when tested)
990fxa-ud3 MB
8 GB Corsair Vengeance 1333Mhz
Sapphire HD7770 Factory OC (tried default clocks for 7770 Ghz Edition)
PSU Zalman HP-850

Problem - annoying flickering textures appearing randomly. Tried different drivers, no success. Haven't noticed anything like that in other games. In-game settings Ultra, CCC - defaults.

Little update. Made sure it was GPU, by trying my old 4870, no artifacts, absolutely perfect picture. In addition i RMA'ed a 7970 a while ago, and it too had pretty choppy graphics in RO2, with these 'leaky' textures loading up in midgame, and flickers of certain textures, like posters on walls. But no such massive flicker, and i guess i did not have such bad flickers in RO2 before with 7770.
Don't know if it matters, installed OS on a SSD yesterday, game is on HDD though, pagefile on SSD, will try to move pagefile to HDD out of curiosity.
upd. tried, nothing changed.

Was a mistake to leave CCC on defaults, i never seek for easy ways sadly, but for now i do not notice these damned flickers after setting triple buffering on. :| well, i hope its the fix.
upd. no, it's not, still flickers.

12.6 drivers ftw. Not only they reduced flicker, improved fps, but dealt with ppsh lag for me.
