NVidia Optimus freezes up Unreal Engine games

I've recently set up my new Arch Linux system. But several Steam games I've tried (such as Oblivion Remastered) seem to keep freezing up at random points in time. Repeated attempts to figure this out haven't solved the issue.

The current set-up uses NVidia Optimus with Prime. The Nvidia card (AD107M) with `nvidia` driver is on slot 0 and a Radeon 680M on slot 1. Running `prime-run glxinfo | grep "OpenGL renderer"` seems to show the expected outcomes.

I'm currently on Xorg with LightDM.

The most suspicious thing I encountered was the output of `journalctl -xe`, which contained the following when a crash occurred:

May 23 08:35:13 - kernel: pcieport 0000:00:01.1: AER: Correctable error message received from 0000:01:00.0

The specific crash reports all include the following:

LowLevelFatalError [File:Unknown] [Line: 1209] GameThread timed out waiting for RenderThread after 120.00 secs

But I can't seem to find a clear explanation on whaat this means. Does anyone happen to know what I can do to resolve this issue?
