Mostly some tinkering with settings can't really remember which onesturning them on and off repeatedly to see if i could really see a difference or if it was big enough to justify the fps drop. With my Rift S if i kept 40 fps and ASW while it was a relatively pleasant experience i did feel some discomfort in longer sessions, but if i tweaked things enough to be able to run 80 fps at all times i could play indefinitely. I have a ti after all, not quite your ti but still one of the most powerful cards on the market. Hmm, maybe i'll have to look into it a bit more. It completely bypasses skyrim's maximum limit of four simultaneous dynamic lights, making dozens of fully dynamic, fully shadowed lights, which can almost incalculably enhance the ambiance of the game.
