DX11.exe errors that I cannot fix, been stumped for months

[Mistrin]

You're telling me lol. I completely reinstalled windows and the game the other night and still get them, been dealing with this for literal months. So close to just selling my PC and getting a new one lmao

This might sound a little silly to ask, but you're using just the regular GPU drivers? If you are, can you try the Studio drivers (if you're still using the 3080 that you've posted originally)? There's something that windows doesn't like between Nvidia's and AMD's regular drivers and how SE has DirectX (9 and 11 both can have issues, but 9 is less frequent) implemented in the game.

So I finally cracked down on my issue, and it's worth a shot for you to try. FFXIV is the first game where my CPU has way less work than my GPU and it will just clock super high when in limsa or any city state while the GPU is rendering everything. There's a point where it hits an instability from automatically boosting while the temps and workload is low, the clock speed is nearly max.

I'm unsure if Intel has a desktop counterpart but I manually clocked my CPU to its base speed with a decent voltage and I have not had a single crash since I've done this. Try researching into manual clocking your 10850k, if there's a way to turn off the boost I'd start there at least.

Unironically, this was one thing i tried and i still kept crashing (Ryzen 7 3700x). I get WHEA logger errors for overclocking, which i thought was being caused by my CPU just doing it's normal boosting, but i'm fairly positive it's how SE has DirectX implemented in the game that's causing a conflict with drivers and how Windows wants to handle it. I was able to recover from a crash (by some luck with using windows GPU driver refresh key combo) and it showed a driver timeout error from AMD with also getting a DirectX fatal error from FF14, and didn't show a WHEA logger error for overclocking. I swapped to from AMD's regular driver at current revision (21.7.1) to AMD's pro drivers (content creators drivers, version 21.6.1) and i flickered a couple of times with complete recovery each time without my own intervention, and haven't had any DirectX fatal errors or driver timeouts.

Did you manually overclock with Ryzen Master or in the BIOS? BIOS settings weren't getting along with what I was doing, but I set my Ryzen 3600 to 3.6 GHz and 1.2V and I have a launch chip. (forewarning to anyone reading misguided, don't copy these settings unless you're also using Ryzen 3000 series though it is still possible to be unstable)
