Swapchain D3D11 bug issue make Unity unusable in DX11

[nasos_333]

Hi,

I have come across more and more on the swapchain issue

D3D11 SwapChain Error Fix

in latest Unity and NVIDIA GPUs

Is this something that is going to be handled ? At this point is a random crashes matter that make DX11 extremely risky to use in an actual game, due to possible crashes on user side that is not possible to recreate locally without NVIDIA 20xx or 30xx and latest Unity.

More on the issue:

I had this error message after using the spline tool in 2023.1. [8502857--1132316--upload_2022-10-10_17-12-51.png] After that the editor crash and when I open it again all of the windows are black.

Constant Crashes - Failed to present D3D11 swapchain due to device removed.

My Unity 2020.1.8f1 crashes constantly, albeit randomly. Every few days. This is typically when I am doing a lighting burn on a level (various sizes and complexity) or using a procedural level generation tool (I use both CityScape and CityGen3D). It is getting annoying, and I am losing a lot of time rebooting to clear the RAM and redoing my lost work.

Failed to present D3D11 swapchain due to device reset/removed

Hi, I’m using Unity 2021.1.3f1 and want to take 360 screenshots inside my game. For that I have “360° Screenshot Capture” installed. This free tool has always run perfect, no issues, any resolution worked. But as of today, when I take a screenshot with 4096 resolution, all works. But when I set it to 8192 and take a screenshot, Unity freezes and after 10 seconds I get this error; I have read different posts on this problem, but I can’t seem to find a solution. My hardware; an NVIDIA Geforc…

Note that the issues does nor happen in DX12 or Vulkan, also not happen in Unity 2019 under any GPUs i tried.

Thanks

Yes, if a shader runs for more than a few seconds, Windows will reset the GPU driver because it means that Windows will become unresponsive. If you have a shader running for that long, you are doing something wrong. You have to break it down into smaller workloads.

I don’t think Unity contains shaders that run that long. If Gaia has such shaders, it’s a Gaia bug, not a Unity bug.

I would agree, but the problem is that the same exact thing runs fine in Unity 2019 and in 1050GTX, it is only in latest unity and GPUs that the issue appears.

Also does not appear in Vulkan or DX12, so is definitly a bug in my mind, and a extremely huge one

The shader does not run for sure for seconds, given even in the 1050GTX the system runs at real time, around 30-60fps

The video below is 30fps in HDRP on my 1050GTX laptop, the same creates the swapchain issue and crashes directly in any NVIDIA GPU from 20xx and above.

I understand though that given DX12 is out make sense that NVIDIA does not care for making their new GPUs work correctly with DX11, cant explain it any other way. So maybe is not just a Unity issue, though the same did not happen in Unity 2019.

Resolved? How?

Having the same issue here with a relatively simple compute shader. Runs fine in Vulkan (MacPro, AMD FireProD300), fine in DX12 / Nvidia RTX 3090, runs fine in most computers I’ve tried which are quite a few, crashes 90% of the time as soon as executed on DX11 / Nvidia RTX 2080 with the swap chain error.
