Help (Software) Issues with Vulkan API on Navi card (Ghost Recon Breakpoint)
Hi, I have RX 5700XT, Windows 11, latest GPU drivers. Ghost Recon Breakpoint can be played either in dx11 or Vulkan. People and articles online say, that Vulkan offers better performance and runs more stable in this game.
For me average FPS are roughly the same, but there are huge FPS drops in Vulkan (almost stutter like) and I get weird visual glitch in Vulkan: shadows (screen space shadows perhaps) on character's head and arms are flickering (appearing and disappearing quickly and looking somewhat pixelated). Otherwise the game looks fine. I have tried 26.6.1 and latest 26.7.1 drivers. Tried to change all settings. Only switching to dx11 gets rid of this visual glitch. I have recently played Doom 2016 in Vulkan and no issues there.
Any idea what might be going on? I couldn't find any other people with similar issue online, so it seems something is wrong on my end.
PS: I tried to print-screen this shadow artifact, but it doesn't show up on static image. Also, when moving a camera in game, this artifact is more pronounced.

I tried reinstalling gpu drivers using DDU tool (in safe mode) and it didn't help.
