Many thanks for the answer!
I will try it. But I note you use Gamma Correction On. Do you have the ball sun in your SH4? Also: AA application controlled....SH4 controls AA? SH5 does it, but SH4 doesn't have any control for AA.
BTW, I have the same W10 version and GTX 770 with the same update as you.
Many thanks!
