Yesterday, I upgraded the 64 bit drivers for my Radeon RX 580 from version 20.12.1
to the latest optional release 21.6.2.
Following that update, 3D models in GZDoom stopped displaying at all, and no warning messages appeared at startup. I rolled the driver back to the latest recommended version, 21.5.2. This did not resolve the issue. I did a complete uninstall and rolled the driver back to 20.12.1, and that resolved the issue.
I am using GZDoom g4.6.0, downloaded from here
. Because rolling back my drivers resolved the issue, I have not tried the latest version of GZDoom with the latest drivers yet. I will be testing that later this afternoon.
If any additional information is required, please let me know. I will update this thread when I have updated my GZDoom and drivers.
