Okay I'm running a 470 GPU on a Ryzen rig with the current drivers I can not Run Hearts of Iron 4 mesg Paradox and they said it's the current drivers I have to revert to 7.17.1 I have tryed to revert to this driver but alas I have yet to get this task done as Windows updates before I can install the driver I have down loaded I would hate to go the other side because of this one problem FIX IT YESTERDAY already. You might ask your self why is this important well when you have 1k+hrs in a game you might see a problem in and of this issue. This is the first time I have had a problem from AMD on the large part come on don't leave a guy hanging.
Here is the mesg from Paradox
This is a probably the bug in recent versions of the AMD video driver, from 17.7.2 onwards.
You can revert to their 17.7.1 version, which still works fine:
The other workaround is to In your Steam Library right-click on this game and choose Properties. Click on Set Launch Options, and paste this in there:
That may impact performance however.
We'd appreciate it if you'd contact AMD support about this, so they'll finally fix it!
You probably need to block windows device driver updates before even attempting to troubleshoot ?
I assume you have Win10 (that's what the link points to).
