CRT EmuDriver update for Vulkan API async shader compiler

[cyberluke]

Hi, I just tried CEMU (Wii U) emulator on Sony PVM and R9 280X. It sorta works, but stutters a lot. Due to old GPU driver I am not able to turn on async shader compile feature for Vulkan API. It directly complains about this specific Vulkan API directive and it is the only way to get Wii U titles working and playable.

Could there be some update? The GPU supports Vulkan 1.2: https://www.techpowerup.com/gpu-specs/radeon-r9-280x.c2398 ...the only problem is the outdated AMD driver.

Video from 2020 (two years old):

It says this: AMD Drivers (You need the Optional Driver 20.3.1 or higher)

Possible solutions:

1) I'm software developer, teach me how to merge or tweak driver files, so I can update it for this community.
2) Replace only some Vulcan API DLL from Adrenalin 20 to Adrenalin 18 (not sure if this is possible)

Hi, i'm running cemu with async shaders with emudriver.

Look for my post, option 2 works fine.

EDIT: Tested pcsx2 v1.7 with windows 7 and dxvk (vulkan to directx wrapper) and worked fine too.

Maybe you work together with Calamity on future releases only thumbsup

So I did something back in 2020 because of the outdated Vulkan drivers. I basically just replaced some files from a newer driver. Just recognized, that I never uploaded them here (http://forum.arcadecontrols.com/index.php?topic=161736.0). I got Emulators with shader problems fixed by this see https://www.instagram.com/p/CEY6OX_nDIP/ .

Here are the installers - https://we.tl/t-J3QaTPEdyR

1. Install the driver from crt_emudriver___tools_2.0_beta_15_18.5.1_W.10-64.7z as usual. During the installation you will get a warning of unsigned drivers. Just allow this installation.
2. Install vulkan-runtime.exe
3. Not required but if you want install the Radeon Settings from radeon_settings_18.5.1.7z
4. I also added a batch file to disable automatic driver updates by Windows10. This was often a problem and removed CRTEmudriver with the latest AMD GPU driver which is a PITA.

I suggest using https://www.guru3d.com/files-details/display-driver-uninstaller-download.html to uninstall any older / prior GPU drivers before installing this.

Hope this helps and fixes the problems that you encounter. If it works out for you please give an answer to also help others.

Hi faxesystem, that upload isn't available anymore, could you reupload it somewhere?
Cheers.

Do you know what exact vulkan-runtime.exe i need for Win 10 aswell so i can play dolphin (i tried directx 12 with that one but crashes)


is this the method? -> https://thegeekpage.com/vulkan-1-dll-was-not-found/

I followed psakhis method in the past but never got vulkan working.
@faxesystem Would you mind sharing this driver installer again?
