Sorry I dont know why but I cant create avatar and signature in my profile...
I have a GTX980 from MSI since few weeks and a 22" screen.
Because the name of your preset, I tested only in the forests of Falkreath and Riften.
Mods used for the vegetation : SFO 2 + TR grasses + Unique grasses + unique grasses plugin + cover wood (4K) + pine forest parallax from Zerwas (4K) + Tamu75 alternative aspen trees.
iMinGrassSize=25 and + fShadowDistance=8000.
With woods preset > around 45 fps in first view, a little bit less in third view.
First feedback of your preset > Unique and beautfiul in the woods. Forests seems "enchanted". You made a great work! Really nice on characters too (but sometimes in interiors there is visible neckseam on my character). When the weather is cloudy the color of the sky is a little bit curious. Nights are pretty well.
If you wich I can publish few screen on the Nexus today or tomorrow. (Nexus user = Poupoulou)
