Return of Reckoning

So DX9 fullscreen Gsync still works, but borderless doesn't anymore. Also I was converting to vulkan(to have sharperning via reshade) and on vulkan It's not working either, borderless or fullscreen, though I think that setting doesn't do really anything on vulkan other than alter the gamma, so makes sense that "fullscreen" vulkan wouldn't work if dx9 borderless doesn't.
Sure before borderless gsync wasn't perfect either it used to only work if there was no gpu accelerated content on other monitors, for whatever reason, but it still worked, now Gsync just doesn't engage at all even with only 1 monitor active and war.exe is the only active window.

Now I tried all the usual gsync issue suspects, disabling/enabling fullscreen optimisations, deleting the program data Nvidia Drs folder, toggling windows vrr, borderless gsync on/off, ofc uninstalling/reinstalling reshade and nothing seems to fix it, I have not updated the nvidia driver either, so can't pinpoint the issue at all, don't think there were any windows updates either.

So is this a "me" issue? I mean the amount of ppl converting to vulkan is probably not a lot, but does DX9 borderless gsync work for any1 still or did it also stop working? And if it does work, what is the magic juice to make it work again?
