Portal 2, DirectX 9, has broken shadow rendering on 5700 XT, driver 21.2.2 on W10 20H2. Renders fine via Valve's Vulkan or DXVK Vulkan. Got confirmation it's working fine under DX9 for Turing as well.
After some more research, it seems Portal 2 DX9 shadows have been broken on AMD GPUs since 19.7.x. So ... 1.5 years now. Cool. I reported it via Bug Report Tool to AMD.
And as a fun fact, Valve's Vulkan implementation in Portal 2 is a bit more performant than DXVK 1.8 Async

DOTA 2 opens minimized under DX9 and is stuck there...performs better under DX11 than Vulkan.
I already had few times this situation:
I have overclocked my memory to 2150 but Radeon settings show that incorrectly. 2150 looks like the minimum instead of the maximum. I can't pull the slider in any directions.
After restart everything looks fine:
But after some time when I try to open again Radeon settings, I see the situation from the first screenshot. I'm not sure if it happens after some games. I don't use external tools for overclocking (like MSI Afterburner etc.).
Got somewhat worse performance with these in RDR2(fluctuating fps, less constant than previous drivers, and looks like SAM/BAR is handicaped here). DX9 is fine again. Dx11 some good, some suck. DX12 quite good.
I just wish some in driver trigger to force GPU work 99-100% in dx9/11 titles as with dx12.
Works really fast for me with RX Vega and stable, plus yes HDMI / Displayport audio is back. I am on DP rn. Using Air boost 64 bios and some reg tweaks, but still, boost frequency seems consistently higher (even with no undervolting). I managed to play Prey without stuttering at around 120+ fps on High at 2560x1080, vsync off. Everything works, and everything is in harmony =) If anyone wants i'll send them my current tweak to try & reproduce
Someone on youtube post same problems with rx580 and rage2, with better cpu from mine:

@passenger have the same problem, as wrote before. (Sapphire rx580 1366 mhz 8gb ram)
@SpajdrEX take a look the video

Nice! 😛 I encountered this when I played it last year. Not sure if it affects other GPUs besides 5700 series or if it was fixed.

Yes exactly the same behaviour, Rage2 is unplayable.
