i’m also using windows 11 and it’s fine here… so i don’t think that’s the problem in this situation
i asked about your os because i imagine it would be a problem if you were on windows 7 (since it doesn’t support dxgi flip model… and unx with the archive from the sk wiki has flip model enabled by default)
when you say no unx changes, you’re talking about the game on its own ? or still with sk/unx but without something else you changed in unx ?
are you crashing when just running the game on its own ? i think that wouldn’t be normal… and in that case i’d also try verifying the integrity of your game files in the steam client and maybe using ddu to clear your gpu drivers and then update/reinstall your gpu drivers
also, not sure what wiki you’re talking about… but you shouldn’t need to disable fullscreen optimizations here… nor be running the game on fullscreen. i suggest using borderless instead. in this case with sk/unx forcing flip model by default (if you use the stuff from the unx archive in the sk wiki), borderless should be performing as good or better than fullscreen exclusive
you could also try using the 4gb patch. it’s suggested for this game but mainly for addressing green screen issues or issues with some textures when using very high res texture mods…
if you want to try that at some point-
https://ntcore.com/?page_id=371
download it from the link above
extract the 4gb_patch.exe
run the 4gb_patch.exe that you extracted
then navigate to your steam game folder where you have your FFX.exe and select it (double click on it or select it and hit open)
you’ll get this at end-
if you get crashes that only happen when using special k with your game… then keep in mind that other tools you have running can interfere with sk. some known to cause issues are nzxt cam, rivatuner, razer synapse, anti-virus…
