So I was able to get AFMF working on another machine running a 6900XT at 1440p 16:9 monitor but for some reason it doesn't work for my 32:9 Samsung g9 monitor, I feel it has something to do with the monitor resolution and aspect ratio that is causing the issue.
the new AFMF2 preview driver is NOW WORKING on my 32:9 display for Suicide Squad: KTJL (micro stutter values do seem a little high though, hopefully that can be improved). Thanks AMD, looking forward to the official driver to include AFMF2.
