FFXIV crashes when trying to apply "fsr31 (native dx11)" if libxess.dll is present.

[Spacellary]

So far I have not been able to use fsr31 (native dx11) from the latest stable Optiscaler release or pre-releases.

FFXIV crashes when trying to apply only that option for FSR. I can use all the other FSR variations, just not that one.

Is that something you experienced by any chance, @MapleHinata? - Apologies for tagging you if that is inappropriate.

Don't try this mod with online games! risk of ban!

[Spacellary]

@sagaopc I'm aware and taking the necessary precautions for this game.

[cdozdil]

Hi, which version of the mod you are using? Have you tried with latest 0.6.8-pre?

[Spacellary]

v0.6.7 stable and v0.6.8-pre4 pre-release

I thought it could have been part of the fix in the notes but unfortunately had no success.

DirectX 11 FSR 3.1.1 backend crash issue with old VC Runtime versions. (thanks to MapleHinata) #70 #71

[MapleHinata]

Hi, send an OptiScaler.log (You may need to enable logging by setting LogToFile=true)
But I added the FSR 3.1.1 backend with FFXIV in mind, and it does work on my end on a Steam Deck and on a desktop with a NVIDIA GPU, and other people got it working on AMD GPUs, so it should be working....

[Spacellary]

Okay, I'll report back later.

I'm running an NVIDIA GTX 1070 Ti for reference, I do also run ReShade alongside so I'll look into that, just has not been an issue until now.

[sagaopc]

Hi, which version of the mod you are using? Have you tried with latest 0.6.8-pre?

I'm tried the build 134 and v0.7.0 pre23

[MapleHinata]

Okay, I'll report back later.

I'm running a an NVIDIA GTX 1070 Ti for reference, I do also run ReShade alongside so I'll look into that, just has not been an issue until now.

I also run ReShade alongside it, with ReShade as dxgi.dll and OptiScaler as winmm.dll, though i can't guarantee compatibility with every ReShade addon (but i do know that RenoDX (https://github.com/clshortfuse/renodx) works, because i use the renodx-ffxiv addon with OptiScaler just fine.)

Nonetheless, without logs, I'm blind here, so please do send it whenever you can.

https://gist.github.com/Spacellary/32723785b83bc6eff11e0ce8c10ad943

[MapleHinata]

I'm happy that you got it to work, I believe the reason why it was crashing with libxess, and the reason v0.6.7-final was crashing, is because your MSVC runtime is out of date, try updating it by downloading the latest one here: https://aka.ms/vs/17/release/vc_redist.x64.exe

[Spacellary]

Heya! Thanks for checking it.

I had previously installed all the VC-Redist suite via winget install, and generally I keep everything up-to-date with regular updates, but I installed again freshly as per your recommendation from the link provided to the installer and rebooted:

I still get this issue when libxess.dll is present:

Let me know if I can provide anything else that could be useful, I'll do everything I can to help troubleshooting.

[MapleHinata]

Huh, strange, @cdozdil was the one that worked on the xess integration, so I'm not familiar with why that is failing
Edit: Question, what are the files you have on the folder containing the ffxiv_dx11.exe file?
It's possible another mod was shipping an older version of the msvc runtime.

Adding libxess.dll makes me unable to launch the game.

What mods are the nvngx.dll,dxgi.dlland dxgi_o.dll files?
There's quite a lot of dlls being injected in the game here and there's possibly a conflict between them.
In particular, nvngx.dll seems to be a duplicate of OptiScaler, and while it doesn't seem to be loaded at the moment, it could potentially cause issues, and i advice deleting it.
dxgi.dll seems to be the old d3d12-proxy, and this shouldn't be necessary these days, since OptiScaler handles spoofing on it's own, and you are on an Nvidia card anyway, so there's no need to spoof anything.
And last, if i had to guess, dxgi_o.dll is ReShade?
Try getting rid of nvngx.dll and dxgi.dll and see if it still crashes.

dxgi.o.dll is ReShade, yes.

I've removed nvngx.dll and dxgi.dll, it still crashes if libxess.dll is included.

Works as expected without it.

I'm using the files from v0.6.8-pre4.

Right now I have:

Seems to be solved with latest pre-release from my testing so far :)
