• Jade empire shadows, flicker
• Kung Fu Chaos
  • black screen
  • blending
• Total Immersion Racing blending?
• Mercenaries Minimap
• SegaGT textures
• conker sampler dims xemu(1).log
• Phantom Crash rect_tex
• texture warping
  • Mortal Kombat: Shaolin Monks
  • House of the Dead 2
  • Phantasy Star
  • Sega GT
• splinter cell meter
• Battlefront 2 HUD flicker (560.70)
• GTA
  • geom
  • blur off
• Gauntlet
• Group S challenge
• FMV
  • Black Stone (pvideo)
  • Brute Force (surface blit)
  • World Soccer Winning Eleven 8,9
  • Forza (pvideo)
  • Futurama (texture blit)
  • Serious Sam (pvideo)
• Halo projectile
• Halo lightmap
• draw time

Note to testers:

• Not on macOS yet. Linux and Windows only for now.
• Machine > Settings > Display > Backend > Vulkan. Restart xemu. You can switch renderers at runtime.
• Some features that the GL renderer has are missing. Expect some minor differences. Please report major differences and obvious bugs not listed above.
• Performance may be better, or may be worse--we are focusing on correctness more than performance rn.

Hey Matt, i haven't been around in awhile but is it possible to bundle moltenVK with this or is there any interest in porting to Metal API as well? I'll do some testing on my vacation next week.

[Lagahan]

Significantly improved performance in Mercenaries (2x scaling, Windows, 7800x3d, 4090)
OGL 1x render scale couldn't hit 60fps in this scene, nvm 2x!

OGL: (RTSS' fps & frametime measurements freak out when fps drops below fullspeed)

Vulkan:

There is interest just will take some work as there is stuff needed to be changed to work under moltenvk. Probably won't be in the pr but we will have to see.

Artifact when using Vulkan renderer.
OpenGL works fine, except for no HUD in Halo 2.

@rizaumami Can you please try the latest build and see if that resolves your issue

It's not only in a game but also in the Microsoft dashboard, so not game issue.
The orangish colour in Halo 2 is different issue (#952?)

[Triticum0]

Breakdown exhibit worse performance on vulkan than opengl
Vulkan 20f/15ps
Opengl 30/25fps

[Triticum0]

Total Immersion racing sound volume bars and car stat bars are not rendered on vulkan correctly.

#109 (comment)

Regarding performance: Vulkan does offer a lot of flexibility but, based on my experimental work, GL is more than capable of reaching xemu performance targets.

Is this still true?

[ehw]

To add to the distortion issue, I changed the internal resolution with the Vulkan backend to 2x and it seems to fix it. It looks similar to the OpenGL backend now but it still seems a little different.

Vulkan 1x:
