Shadow and Alpha-textured surfaces flickering with AMD Radeon RX590

Development Rendering

Hi guys!
I’ve got two PCs, one with GTX 670 (yeah I know, I know… ), and other with RX590. First one is pretty slow but no graphic issues. With RX590 I get terrible flickering with Alpha surfaces (tree leaves for example). This can be fixed with TAA, so that is nearly ok

But the issue is that the same problem I have with Shadows. And thats where nothing helps (or I don’t know where to fix this)

Attached is the video with indication of both problems. https://youtu.be/ciBUIuqr6C0

P.S. actually it will be interesting to know how to fight the first issue without AA at all. Is this a real problem with Radeons?
P.P.S. Funny, but I previously had Radeon card 10 or 15 years ago and it also had some weird Alpha -Blending…

hi @mr.dRob,
common problem first you need to download Get Drivers with AMD Auto-Detect and Install Tool | AMD
Lots of people thing drivers dont matter but they do and the install tool gets the RIGHT driver.
There are so many drivers to fix so many problems.

Forgot to mention, drivers were installed yesterday, I took the most recent from the AMD website.

Just out of interest I used the Auto Installer you mentioned in your post, and nothing changed (despite the AMD stupid installer Re-Downloaded and Re-Installed the same driver version)
