Go to https://mrhaandi.blogspot.com.au/p/injectsmaa.html and download version 1.2. Drop the CONTENTS of the d3d9 folder inside your skyrim directory (4 files) and it'll just run. If you're running ENB, it'll conflict, you'll need additional instructions. Google SMAA + ENB ;D I haven't used SMAA yet. How does it look compared to other AA methods and how much VRAM, if any, does it save?
I have found that some AMD setups cause stuttering. I used to have a gtx 560 ti 1 gb and I got no stuttering from vanilla skyrim but then after upgrading to crossfire 6950s 2gb i had massive stuttering. From what I've experienced, bethesda games are not really ATI friendly.Â
