Not specifically related to Nvidia drivers, but I and another user have discovered a DXGI Bug on our Machines related to Volumetric Clouds (loading in with Volumetric Clouds on and with any kind of Precipitation causes a DXGI error and often a CTD, EA on it's own is fine). We both use the same GPUs which are the Radeon RX570.

I don't know if anybody else has had this on Nvidia hardware or other AMD cards, but very reproducable on my machine. Though I suspect this is more down to the poor implementation of Volumetic clouds than driver problems.

Thought I'd bolt it on here rather than make a whole new thread as there's no solution I know of beyond disabling Volumetric Clouds (which most people on here seem to dislike anyway).

Well worth reporting to LM on their forum. They rarely respond but do read everything I’m told.

I only tried EA briefly and didn’t like it with or without volumetric clouds.

I've hardly bothered with the DX shader cache since adding those entries in the Registry. Not one DXGI problem.

Hi Ray , can i refresh your memory ? I only had one entry " the TdrLevel=0" in my reg and just had a Hung_error for a very long time leaving T2G LFPG at night

What the second entry :-)

Thanks

TdrLevel=0 won’t work. See below..

To save searching for my post on solving this problem I’ve pinned a topic to the top of the P3D forum.

So 32 bit then  , i thought it was 64 bit ?

It has to be 32-bit.

So to summarise what seems to work for me is this:-

• Nvidia 471.96 Game drivers seem fine for me. Later ones may be fine but I'm sticking with these for several more flights.
• Start RegEdit in Admin mode.
• Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\GraphicsDrivers
• Right-click right pane and choose New.. DWORD (32-bit) Value
• Name it TdrDelay. Double-click it and enter a value of 60 decimal
• Right-click right pane and choose New.. DWORD (32-bit) Value
• Name it TdrDdiDelay. Double-click it and enter a value of 60 decimal
• Exit RegEdit and reboot.
• Install Realtek sound drivers if not already installed.

@Ray Proudfoot - I just noticed that the HKEY is in the "ControlSet001" sub directory and not in the "ControlSet" as had been originally advised somewhere way back at the beginning of this thread.  Do you know where this change came from?

Mark,

a quick search suggests it should be CurrentControlSet. I’ll check my PC tomorrow. I’ve hidden the pinned topic for now. I suggest no one makes any changes until tomorrow when I can confirm my own settings.

Good spot and sorry for any mistake.

The correct path is:-

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

Sorry for the incorrect path. Don’t know how that happened.

Thanks for confirming Ray.

I haven't read all 445 replies (so far) so maybe this already has been mentioned.
So I'm not sure if I'm contributing or not.

If you want to do a genuine proper 'clean' driver install, follow the instructions of JayzTwoCents.
It opened my eyes.

 

and please..... don't shoot the messenger... 😁

I didn’t watch all of it but the accepted method is to use DDU in safe mode to uninstall then install the new version.

Affirm, but also disable automatic driver download in System Properties and Windows Update (The latter two, I didn't know)

I’ll check later but I’m pretty sure they’re both off as I’ve never seen driver updates in Windows update.
