[d3d11] Risk of Rain 2 object flickering.

m-soweli commented 12 months ago

When playing Risk of Rain 2 once in game, parts of the level pop in and out of view, even if the player is not moving. Sometimes objects flicker in and out of view rapidly. It seems to depend on the proximity to the camera.

I have tested this game with forcing DirectX 12 instead of DirectX 11 and I cannot reproduce the flickering, so I do not think that this is an issue with Mesa. Unfortunately the game crashes frequently when using DX12.

DX11 and DX12 can trigger different bugs in the driver, on Intel I would always suspect a Mesa/driver issue first, unless it's proven to happen on AMD/Nvidia as well.

You are probably correct. Looking into this it's rather likely that this is this mesa bug. I will add to that report with my traces.
