I changed the renderer from DX11 to Vulkan in the pdx_settings.json. My GPU runs at 45c after 3 hours of office, skype and other not graphical challenging software. I now compared my GPU usage and temp in CK3 and Vicky3. When I play CK3 with Ultra settings, my GPU usage is at 100%, the temp stays between 60c and 70c and the GPU fan keeps quiet. Added to OP. Had this issue too, it's one of the checkboxes in the graphics settings, can't remember the exact name but it's something like texture filtering/mapping. It’s advanced shaders. Weird. And it impacts performance. Why CK2 terrain looked way better. CK3 is just ugly in general. I don't know why nu-Paradox fans love CK3/I:R I dont think spending more on the GPU makes sense, considerding current pricing. But if the game is really CPU-heavy i might want to get a 5800x instead. (assuming it reduces loading times and such). And maybe a RTX3050 is overkill for CK3, i dont know. CK3 isnt exactly the game people benchmark so its a bit harder to get info on whats worth it.
I have uninstalled and reinstalled, rebooted, forced use of the Nvidia GPU in Windows graphics settings, Nvidia device manager, and updated to the latest driver for my GPU released on Feb 14, 2022 but still am having the same issue. Other games continue to use the Nvidia GPU fine with not noticeable problem. Please explain how to reproduce the
When you uninstall a Paradox game, it doesn't get rid of the documents folder it creates (which contains settings, saves, etc.) that's separate from the game files. Go to your Documents folder and then Paradox Interactive\Crusader Kings III, and delete the pdx_settings.txt file. When you start the game again, it will recreate the file with
I have map stuttering with Gsync, 100-160 fps, and 160hz (3840x1600p ultrawide). The only thing that alleviates somewhat is turning off vsync in game. Byt then I still have these furiating micro stutters while strafing the map. Other than that I've tried turning on/off every single setting in NVCP and in game without any difference. 0dkHA.
