Game crashing whenever I try to play in borderless window mode or press alt + tab

[Rizyu]

After having a clean boot crash my PC to the point of having to hard reset my main HD with the windows OS on it. Try this for I kept getting Dx11 errors from just 1 quest. Uninstall ff14 fully and do a clean reinstall. Mine worked and Im still salty at support for even suggesting the clean boot (and even my cousin that works for Microsoft is wondering why they said for it can cause a lot of issues like I just had)

Good afternoon!

Yes, the crash also happens when I try switching to windowed mode

As for DSR, my GPU doesn't support it (Well I wasn't able to find any options about it on the nvidia control panel)

I've tried the clean reinstall once but it didn't help, actually but I'll try again I guess

I wonder if the driver 451.67 is the problem, but when I tried using another driver the error still kept happening

Thank you everyone for your answers though!

FWIW, your GPU does support it, but it's not labeled as such on the control panel. It's just a matter of going to the Screen Resolution part of the control panel and adding custom resolutions larger than your monitor. They'll show up as valid resolutions, but if you set a game to use one, Nvidia's DSR functionality will take the larger renders and scale them down cleanly to match the monitor resolution.

However, it has to be set up manually. So it sounds pretty definitive you're not using it, and thus it can't be the culprit for you. (Unlike for me, where it happens when I swap to an absurd resolution via DSR in order to take screenshots, and then tab out without thinking.)
