Sounds interesting.
When you say, checked every box, you obviously don't mean checking the timesplice boxes (and so actually lowering graphic quality) too? Cos ticking just the one shadow update box is all I need to tick to double my framerates- at the expense, of course, of moving shadows, frankly no great loss anyway as they look like crud anyway.
So this fix removed all that stuttering you get, for example, when hooning around the fjords in dragon form? Nice!
