My friend and I run the same x-fired cards ( R9 200 series),we recently updated to the 18.4.1 drivers and broke the game.Loading into the game is horrendous and textures go purple,no amount of tweaking the settings will make the game run as normal. I had to roll my drivers back to 17.11.1 just to make the game work again.
My friend has no such luxury as he runs other programs that need the updated drivers.
We’re aware of some issues that AMD hardware can cause when running Conan Exiles. We have a post with common issues and workarounds here:
If you continue to have trouble after using the workarounds found here, then please consider opening a tech support ticket at help.funcom.com/. We’ll be happy to help you in any way that we can.
That workaround thread is old news. Those solutions are no longer needed since CE updated to newest version of UE.
I also had the issues you are having when I built a new system. The GPU was overheating. I lowered the clock and voltage a tad and works fine now.
CE runs GPUs hot. It’s the only game that does it. I ran multiple stress tests with no issues, but CE would crash.
