Is it due to a higher workload required to smooth the shadows that they are going to be jaggy? I'm just curious because the objects casting the shadow look smooth.
Well I've been doing some testing and when I've applied GPU side supersampling AA to enhance the in-game post processed FXAA the jaggies were greatly diminished vs using the post processed FXAA alone..............(Crimson driver AA set to "Enhance Application Settings" then AA method set @ Supersampling)
I've also disabled the in-game FXAA then set AA up at the Crimson driver level to "Override Application Settings", set max AA level @ 8xEQ (same as 16x), max AA filtering @ Edge Detect and max AA method @ Supersampling (all this is applied at the GPU side) and the game graphics look the absolute best including the jaggies when AA is applied thru the GPU vs FXAA on the post processed side (shaders). Now when I use these settings w\ AH III Dx11 version I get no GPU performance slowdown at all but when I run these settings thru AH III Dx9 version the GPU performance tanks badly to utterly unplayable levels...less than 10 FPS. I have recorded graphs of all this as well for records. This is also why I suspect some issue(s) between the 2 versions of Dx....IMM the GPU performance disparity shouldn't be this wide between the 2, especially w\ the greater performance disparity being towards the older Dx version.
Would\could this also be just due to post-processed FXAA not being as able to do as good a job of antialiasing as the GPU applied antialiasing at this time? 1 of the advantages of using post processing graphics rendering techniques is to offload the GPU of this work to improve overall graphics performance............correc
t?
Or is it just a matter of the choice of FXAA to use? There are several levels of FXAA to choose from as I understand it (also have seen thru using Radeon Pro w\ earlier Catalyst drivers and thru research on FXAA) to be used w\ varying pros\cons.............
Just putting this out here to chew on................
