"AMD also notes that for the time being, support is limited to the Radeon RX 5600 and Radeon RX 5700 series GPUs."

Thats really odd. HAGS has been added with the 2004 update. So if you had this issue before, maybe there is another problem with your system. This will not activated automatically. So if you dont have this option it is a good sign that your issue is not related to my solution. Also my Blender does not crash it freezes at random places when rendering. somteimes at the bhv stage sometimes before it wants to render a tile. So good luck.

Also your 1080 ti should support HAGS. (Hardware accelerated gpu scheduling)

Someone had the right idea back in June 30th

I don't see why Moving the scheduler to the GPU would make blender crash or time out. While interesting, while would I want to move the scheduler back to my CPU instead?

Nice work around.

That is the reason why it suprised me. I didn't change anything. The latest windows update was the reason.
As i have seen in the debug logs / sources i think the problem is that the multithreading timing is broken in this case.

(I just left a comment under the other thread) This is odd - I can't find that GPU Scheduling setting, or Hardware Accelerated GPU Scheduling mentioned under the Graphics/Display settings screens in Windows 10.. I've looked up step by step guides and I'm missing that part completely!

#MY SOLUTION#
Hey.
I had the same issue on my win 10 after the latest win update.

Hard to find a solution for that in the net.
