Crashing Final Version

[76561199232599088]

Have constant crashing after getting 4 hours deep into it, demo was fine never had an issue there, running a Steam Deck but running Windows 11 instead of Proton, overclocked undervolted.

I know this game is going to struggle on Steam Deck period but I just got to a town after the forest level, what I am noticing is the GPU locks up and vram goes over 4GB in my overlay to trigger it then game crashes the Deck requiring a reboot.

Tried removing overclock undervolt of course despite even newer games being fine thinking it was that, nope, UMA set to 4gb to let video card use 4gb, actually almost got into the level after this step however froze up within 30 seconds of being in the level. Deleted the shader cache several times, Tried OLED and LED GPU drivers, running it with dx11, dx12, borderless, full screen.

Anyone else playing this on Steam Deck and having issues? I am starting to suspect Proton maybe allows vram usage to hit almost 8gb stopping the crashes whereas when you go and run Windows 11 on a Steam Deck, it cannot do this for some reason. Might be time for me to figure out dual boot I guess unless this is a wide spread issue.

Disappointing I know Square Enix warned needs minimum amount of VRAM but surprised the game made it 4 hours in then this happens, maybe a memory leak going on somewhere who knows. I was getting around 30fps FSR 1.0 everything set to low.

This is a big issue for a lot of people with high end PC specs. Square Enix refused to acknowledge the issue. I request a refund. Will not buy anymore Square Enix products.

For anyone running Windows 11 on Steam Deck trying to make this game work.

Look up, NEW Amernime Custom AMD APU Driver for Steam Deck running on Windows 10/11 Now Available!

The Steam Deck GPU drivers on official website for Windows 10 11 seem to not have proper fixes to run this game.
Some smart individual made unofficial drivers for the deck that register the custom GPU as an ATI RX670 thus letting you get the updated drivers Square Enix claim are the problem.

Although I got one crash after shader compiled all over again where it locked at a loading screen, 2nd attempt and 10 more after that I have made it past that stubborn part now and noticed....hey my video ram usage isn't going over 4gb like it was before.

Square Enix in all fairness did warn about having 8gb of vram I guess they weren't wrong. Steam OS which is Linux based somehow seems to allocate more than 4gb of video ram on the 16gb total ram console hence reason no crashes. Many people with APUs probably going to run into issues as the APU shares vram with system RAM, if drivers malfunction APU won't get enough ram hence crashes.

Right now getting 25 to 30 fps which is playable I guess there is videos showing it running at 40fps on proton I may find a way to dual boot and run it there instead of Windows 11
