Interesting - I must remember to do some testing to see how flicking can be reduced.
Yes SMAA , FXAA and all other effects that require it are now correctly separated into their own pass as needed so they can be applied without conflicting with each other.
The order is :
Cartoon
LumaSharpen
SMAA
FXAA
Bloom
HDR
Explosion
Advanced CRT
PixelArt CRT
+ the rest in a single shared pass, because they don't need to have their own separate pass and so running them in the same pass is faster because every time you do an extra pass there is a slight performance overhead.
I try to list the effects in the settings in the same order they are executed but the order doesn't currently completely match the code, because I've been moving some of the effects. I will try to remember to make sure they match when the final is released.
