So I decided to crank the settings back up to get my load to 100% so i could tweak settings and keep stable frame rates, so i turned AA, glow and SSAO back on frame rates were fine flat 60 then i noticed a few drops over time ram and CPu use fine so I decided to turn the settings down one at a time to tweak them and get better frame rates.
In the end I turned AA, glow and SSAO off totally again but there was zero effect of frame rate of GPU use. So i'm left wondering what happened between my having them off, turning them back on then off again.
