Conan Exiles lighting is still broken in the latest drivers 18.5.2.
I forgot to add my system specs:
Radeon Software Version - 18.5.2
Radeon Software Edition - Adrenalin
Graphics Chipset - AMD Radeon (TM) R9 Fury Series
Memory Size - 4096 MB
Memory Type - High Bandwidth Memory (HBM)
Core Clock - 1050 MHz
Windows Version - Windows 10 (64 bit)
System Memory - 64 GB
CPU Type - AMD Ryzen 7 1800X Eight-Core Processor
Looks like its not the lighting itself, but objects that enclose light boxes become transparent. What happens then, it causes light boxes and other lighting glitches to form. This bug was not present in 18.4.1 drivers.
I don't want to go back to that driver, 18.5.2 fixed the stuttering in Conan Exiles. I'm guessing that was related to the Amd cache fix.

Can you provide reproduction steps and point to which area in the game shows this issue?
