Hi Neo :)
A couple of settings you suggested but may well have been a matter of choice anyway:
ReservedMemorySizeMb=512 (this was set to 256 but 512 seems to have made a large difference in reducing stutter)
VideoMemorySizeMb=4096 (my vid card is 3072MB but I saw a suggestion that you can alter this to RAM+VRAM-2048. I have 16GB and 3GB so a slight increase over the original 3072 value I had).
EnableVSync=false (allowing my driver to take over)
EnableEdgeAA=false (to increase fps (slightly))
Although ATI GPUs are pretty hard workhorses, they're far too noisy and I'll be looking at the Asus GTX 980 at some point which should help with other aspects. I'm finding a single gpu to be a little underwhelming with ENB and have been using ENB indoors and flat gray drab Vanilla renderer outdoors... pretty sucky but whatever, you do what you can to stabilise :) I also increase iMinGrassSize to 20 as, although it looks awesome, the extra grass was destroying my fps.
Oh, and thanks for all the hard work, testing and research you put into making a great mod pack :)
