Long story short, all recent amnesia games are unplayable on my laptop due to a driver bug that causes severe visual glitches. Frictional games' engine uses opengl, no options for other apis. The fix for the glitches is using Zink, which translates opengl to vulkan and fixes the glitches in the process. On steam, I do this using steamtinkerlaunch. That's not an option on heroic as far as I know, and I wasn't able to find any good info on the internet about how to get Zink working outside of steam or native apps.
TL;DR: how do I go about enabling the Zink wrapper for games installed from epic?
