even if laptops are “more unstable” this problem is not a thing of laptops, it’s either a UE4 or an Nvidia problem but UE4 is doing something that the driver doesn’t like. apparently this issue is more common on GTX 970’s - which I have both at home and at work. At work I swapped it for a different GTX 970 and the issue kept appearing, then I swapped for a GTX 1060 and I stopped having it, then I had to go back to the GTX 970 and the issue came back.
the crash always seems to appear then the GPU’s memory is full. I actually have a fairly reliable way to make it crash in the editor - I open a series of editor windows, I alt-tab and work in 3dsmax and leave UE4 in the background, and within 15-30 minutes I’ll get the crash :rolleyes:
Using older or newer drivers doesn’t help, disabling Ansel doesn’t help, disabling Nvidia experience doesn’t help, running UE4 in DX12 doesn’t help (because UE4 on DX12 crashes on startup). buying a different graphics card that may or may not have the issue isn’t acceptable (since no other game or software has the issue).
But most of all: **any of these solutions that might be acceptable for me as a developer is not acceptable for the users that are experiencing these crashes with our game
