Summary
Hi, every time I launch Tekken 8, i receive this fatal error message. (i have also tried other UE5 games such as Layers of Fear with no success).
The problem started today after I installed my new graphics card RTX 4070. I first ran DDU in safe mode to wipe all AMD drivers, then physically installed the new GPU with the newest drivers available.
Here are the things I have tried:
Windows Safe Mode DDU Reinstalled Nvidia drivers again
Ran the game with Windows 8 Windows 7 compatibility mode
Ran as admin (both the Tekken 8 and Polaris files)
Verified file integrity on steam
Applied -sm5 -dx12 -dx11 in the Steam game properties launch options
Reinstalled the game
Disabled all overlays (steam, discord, nvidia)
Removed GPU undervolt/overclock
Set GPU as default in Nvidia Control Panel
Deleted Tekken 8 Cache from %Appdata%
Deleted temp files
Deleted the polaris folder, then verified files again
Tried using only 1 monitor instead of 2
Updated BIOS
Disabled Hyperthreading in BIOS
Disabled Virtualization in BIOS
Installed various C++ files
(vcredist2015, 2013, 2012, 2010, 2008, 2005, x86 & x64)
Reinstalled DirectX
Turned on and off Hardware-accelerated GPU scheduling (in Windows display settings)
Turned on and off Optimisations for windowed games (in Windows display settings)
Changed Shader Cache size in Nvidia Control panel to unlimited.
Set up TdrDelay in the registry editor (tried set to 0, set to 10, tried deleting it)
Lowered core clock -100mhz on MSI Afterburner
Lowered power limit of GPU to 70% on MSI Afterburner
Disabled XMP profile
Reinstalled Windows completely
I have not tried changing my GPU power cable? I believe I use a daisy chain cable from 1 slot in the PSU.
I am unable to get through the loading screen for more than 5 seconds before the game crashes, so I haven’t been able to set the game to borderless or windowed mode.
It makes me very sad that I bought a new graphics card, only to find that I will never be able to play an Unreal Engine 5 game
