Curse 25 frames. (The Witcher 2: Assassins of Kings)

Hello. I will try to be brief. There are 3 video cards PECH275 PECH550ti and PECH1060 (6GB). I passed the second witcher at 275 and 550 in "under" fullHD resolution at the highest settings. and if the 275 handled 20-25 shots tightly and justified the name, warming up to 100 Celsius! before 550 it was about 10% more productive and twice as cold.
But now time has passed, and I passed the THIRD witcher at 1060, with a resolution of 3440x1440, at the maximum mood, even with hair on the armpits! FPS 35-45 depends on the terrain, with drawdowns up to 30!
At the same time, the same 550 third pulled at medium-high in a resolution of 13 ** x75 * (a little more just HD)

Vod decided to try the second witch, and what was my surprise when at maximum settings at 3440x1440 (by the way, UWHD does not work, on the sides of the strip, so the actual resolution is less) I got 25-35 FPS
I understand the optimization is bad, but damn it , the third half as voracious comes out or what? then why doesn't 550 take it out? little memory ... hmm .. it seems to me somewhere else a dog is buried. the latest version of the game. Now I'm downloading 1.3 but I don't think it can solve the problem.
