New GPU installed: Affinity Photo requires DX12, but I have it already

[flatline]

I switched my GPUs, removed the older drivers with the official tool from the maker, and installed the correct drivers for the new GPU.

I can see on DXdiag I have support for DX 10 (and 9, 11 and 12), but still I get the warning message whenever I open Affinity Photo.

 

I tried uninstalling and reinstalling Affinity Photo, still get the warning.

Hi @flatline,

Sorry for the delayed reply. 

I wonder if is't just some leftover registries from your previous card. Can you try to create a new user account and see if this message goes away?

It's failing to use the GPU for rendering, so we're falling back to WARP, which isn't great, but will work (it's a software renderer, so will be slower). I don't know why it's failing. Just to double check, have you restarted your machine since installing the drivers? Can you upload your log file, %APPDATA%\Affinity\Photo\1.0\Log.txt

I could fix the issue (which was not caused by Affinity Photo), but thank you all for the replies.

For reference in case anyone runs into it into the same problem in the future:

A corrupt DLL from my previous GPU was left in the system and not removed by the GPU maker's own uninstaller. I used this free tool from "Guru3D.com" called Display Driver Uninstaller in safe mode without network (otherwise Windows would re-download the driver automatically) to delete both the previous as well as the current driver. I also manually uninstalled the driver using Windows Device Manager. Then I installed the driver again and the issue was resolved without having to reinstall or even change any configuration in Affinity Photo.

I was going to suggest DDU too, that's a great tool 🙂

There is another tool that can be used to find "driver corpses" that may cause unexpected system crashes.
