Hi,
Just a tip.
If you have unexpected crashes notice or a strange behavior when using one of the Topaz apps you should consider uninstalling Asus GPU Tweak, whatever the version and whatever the GPU you are using. I had serious problems with version II, ditto with version III.
Similar problems with the Nik Collection plugins are also immediately fixed after uninstalling Asus GPU Tweak.
This tool might be useful for gamers but it’s terrible when using post-processing apps.
