DX12 Failure - GTX 780

[svmlegacy]

The most notable issue is Civ VI, but there seems to be a variety of issues.

 

Civ VI will only start a game in DX12 if AA is disabled. Will have a variety of glitches, including missing hair assets. Error is along the lines of "Failed to start video device"

UserBenchmark will not finish the video card test.

 

Things I've done to troubleshoot already:

Updated to latest NVIDIA Driver

Windows SFC, DISM. Both come back clean.

Verified Integrity of game Files via steam

Ran the DX installer in Steam Apps Redistributables

DDU, allowed Windows to install an older (Known good) Driver.

Clean installed latest NVIDIA Driver

Brought Windows completely up to date onto 2004.

 

The issue persists reliably. The only hint I have is in DXDIAG:

System reports DX12 capable:

Feature level is max 11_0:

 

I'm looking to run Civilization VI in DX12 with AA on, and to properly finish UserBenchmark.

 

Thanks in advance for your helpful advice.

Looks like the GPU crashed from instability, what temps is it running? I know Kepler was shit at DX12 when I had it but idk if Nvidia fixed DX12 supports or not, so either that or the card has hardware issues, maybe some deep seated hardware issues. Have you tried a fresh install of windows or another PC?

The card idles at 37°C (The card sees no load before erroring out) and is rock stable for any DX11 or OpenGL game I throw at it. Load temps are 80°C, for a reference blower card. Not overclocked or otherwise out of spec operation. It definitely ran this game just fine a few months ago, but I just picked it back up last week, and have been dealing with it since.

 

Windows has been updating my computer and causing much havok lately (Pretty much monthly i've gotten "Hi..."), I suspect this could be part of it.

 

I am not able to test the GPU in my second machine for a few weeks away, and definitely cannot reinstall the OS until the school semester is over.

What was the card doing when you didn't have it, sounds like that might be a lead, or possibly yeah Windows breaking itself is common

Sorry, the card has been in my system the entire time. I had "picked the game up" again.

Ah. Either something broke in the mean time and only CIV VI uses, the game updated and changed how it works, or Windows itself may be at fault, those seem the most likely. See if event viewer has any addition infomation about the crash/errors
