D3D11: Removing Device crash after multiple minutes of idling

[bradyrussell]

I noticed when I would leave the game running and get off my PC, when I come back it would be crashed due to D3D11: Removing Device. Each time in my testing it happens after two or three minutes after activity stops, see logs where autosave is every minute

this was in a Play in New Window session

[bradyrussell]

this is very likely related to #32 and I have to say this seems new, i definitely have let the game run for a while previously. the only other thing it could be is a view dist of 5 making it occur in <10 min. ill try playing with lower view distance

[bradyrussell]

this does happen in cubic mode as well. this is present in 4.22 VoxelShooter

[bradyrussell]

fantastic I have a copy of the plugin on 4.22 that has the issue and one on 4.22 without the issue (PlanetVox2) tomorrow I will cross reference the rendering (also I like the textures, lighting and Worldgen dont forget to migrate)

[bradyrussell]

it looks like this still happens as of rmc v 4 update however its only when the game is left completely idle. ive seen some reports of the same issue in other ue games so im assuming its something to do with the GPU trying to save power and turning off.

it is not an issue if for instance the player is moving, even if no input is entered for 10+ minutes in an autorun situation

[bradyrussell]

This may be related to Geforce experience?

I'm switching to dx12 to see if that helps

[bradyrussell]

This has not happened since switching to DX 12. I am content with making that the minimum requirement.
