Hi,
I have Nvidia GTX 680M. (Windows7x64 on an MSI gaming laptop GT70 0NE) I found the following worked for me:
Enduring lots of crashing! I ended up reverting my Geforce drivers from the latest vesion 382.53, to the now year-old older 368.81 Worked ! (Release Date: 2016.7.14) .
But then I discovered this was working very slow navigating and causing menu artifacts in Blender and was slower than it was using the newer drivers (though reliable) in UE4
I found the answer in a couple more steps and everything is sweet ! I used the Nvidia Control Panel:
set:
- Manage 3D settings > Global Settings > Power management mode = Prefer maximum performance and
- Manage 3D settings > Program Settings > UE4 to use “High-performance NVIDIA processor”
I turn the Content Browsers, real-time thumbnails off on most projects, a habit from the crashing days and I also have kept a mod in the Registry, that did not work alone and I doubt it makes a difference, but here it is:
- First navigate the key path HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers , Right click on GraphicsDrivers and go to new> DWORD (32 bit) value
- You will see a new key appear make sure to name it “TdrDelay”, Right click it and select “modify”, Under Value data enter 10 (decimal)
As I said everything is now so, soooo sweet!
Edit 07.24.2017 : 3 days of heavy use and it simply does not crash at all. Heartened by how stable it is I let several programs run concurrently such as: a couple of cloud syncs, Firefox including streaming Youtube tutorials, Thunderbird, Blender, OpenOffice, PDF-Viewer and several background services (antivirus, Afterburner, etc)… all at once. Great.
So plenty reports by Nvidia GTX users crashing their games and editors, are suprising for a game engine, by nature dependant on good graphics card. On my end I used the editor, I wasn’t running a packaged game, I wonder if it’s the same on the gamers’ end? I was even more surprised that unlike the plenty error complaints, there is little record of cures. I tried several proposed fixes. Unfortunately due to haste and frustration, I have not kept a good record. I remember VAQUELY that among things are tried are a few switches for the engine regarding opengl, dx12 (both of which were not supported for my gpu), turning of the content browser thumbnails and somekind of graphics card latency value editing the Registry. None worked.
Here is the most extensive reporting of problems and solutions, that I found helpful - I tried most suggested solutions before switching to an older driver.
