I’l be making a separate post for this as well, but it appears as though mesh streaming isn’t working for ryzen 5000 series.
you can disable it by going to “steamapps\common\Warhammer 40,000 DARKTIDE\bundle\application_settings\settings_common.ini”, within the ini file you can find “mesh_streamer_settings” and set disable to true, your game should look normal when you do that.
I noticed loading times became longer though, and there was some hitching sometimes. No idea what other performance implications it will have.
