I finally managed to resolve the issue I was having when using DLSS for AA caused the game screen to be quarter size when using this mod. eg.
This post here made me go back and look at my MSFS 2024 installation folder, where I discovered that I had previously installed DLSS Tweaks to be able to get DLSS Ultra Quality. Removing all its associated files has fixed the issue and I can now use DLSS AA with this mod, so yay!
While I can get this mod working perfectly on SU4, it does not work in the SU5 beta at all (even with a completely clean install), causing MSFS to CTD as soon as DLSS FG is enabled, then MSFS will not even start again. The only way to get it working again is to change FrameGeneration in the UserCfg.opt file from DLSSG back to NONE. Does anyone else have this issue with the SU5 beta?
Edit: I tried it again in the just-release SU5 Beta 1.7.21.0 and it still freezes up when selecting DLSS FG then never starts again until I change it back to NONE in the UserCfg.opt file.
