Hi,
we’re currently rendering a levelsequence in UE4.22.2 using raytracing features.
We’re pushing it to the limits by using 64 samples for raytraced reflections and rendering in 4K resolution.
RAM: 128GB
Card: GeForce RTX 2080 Ti
Platform: Windows 10 (newest)
Driver: Version 419.67 creators ready driver
The original newest GeForce driver didn’t work with 4.22.2 (after upgrading from 4.22.1), as it crashes the driver on loading the scene, so we installed the creators ready driver.
As there is no possibility to downgrade UE4.22.2 to UE4.22.1 within the Epic Games Launcher, we would like to fix this problem.
We enabled the Nvidia Aftermath to debug the crash error, but don’t get anything out of this error message.
Does someone here have an idea or any other possible solutions?

there has to be some kind of bug.
Crashes happen randomly. Sometimes rendering after half an hour, sometimes 5 minutes, sometime after 8 hours.
