S!
Congrats on new card but why on earth PSEUDO?! USe Full Screen. Also put off SSAO, does VERY little for the stutter and lower FPS it causes in some cases. Also building detail to MEDIUM does not affect your visuals the slightest but again a bit more performance. Forest is good enough with Medium already. That antialiasing is as said before, use 2x. Biggest impact you get by setting Effcts to medium, even then they look good but with less effect..worth trying
And again..grats on the card
