I actually tried K ENB at 4K with some tweaks of course(otherwise it's impossbile to run), even my pitiful 280X Toxic managed to give me around 10-18 FPS in outdoors. I'm assuming these badboys can handle 4K quite well, especially with SLI. And also I made some changes in my ini files, draw distance was huge, uGrids was 9 and etc... Even then managed to get around 15FPS at Whiterun outdoors. A new era for Skyrim has begun :P
In the section of 3.B.1. Optimize FOV, it says that adding fov tweaks into ini files does not persist and therefore it should be done via console ingame. I didn't quiet get what does not "persist". I have these lines in my Skyrim.INI under Display section; fDefault1stPersonFOV=81.0000 fDefaultWorldFOV=81.0000 fDefaultFOV=81.0000 I've been playing every save with these INI tweaks for the last year and I didn't have to make any changes since than. Am I missing something here? These values were 65 in the default.ini(the one that you get by typing saveini on a fresh game) and then I just changed it to 81 and it works. I never had to type fov 81 ingame with these tweaks. I usually play in first person. P.S. Excuse me for my poor English.
