Developer Philip Rebohle is continuing to advance DXVK, with another major release now available today.

DXVK 1.2 includes a slight rework of command buffer submissions, to make them run on a separate thread. This should hopefully increase performance in times where you're CPU-bound. Additionally, command buffers are submitted more frequently, which should avoid some stalling and also increase GPU utilization.

Rebohle has also been working on DXVK-AGS, an experimental implementation of AGS D3D11 extensions for DXVK. To allow this to work, DXVK now supports rendering features not in the official D3D11 API but exposed by special vendor-provided libraries.

As for bug fixes and other improvements in this release:

  • Minor reduction of CPU overhead in some games
  • Fixed an issue that would cause redundant state cache entries to be created and identical Vulkan pipelines to be compiled multiple times
  • Fixed an issue that could lead to incorrect Vulkan usage or crashes when using the D3D11.1 ClearView method
  • Mirror's Edge Catalyst: Disabled NVAPI hack to avoid issues on Nvidia GPUs (PR #1046)

Find the release notes here.

Reminder: DXVK is part of Steam Play, it makes Windows games that use D3D11 and D3D10 run with Vulkan in Wine.

How much overhead (%)DXVK cause in the DX -> Vulkan conversion?

Different for every game, it's not a standard % thing, no such thing would be.

In 1.2 one core stay at 100% and overheat non-stop, back to 1.1

This stage is problematic on real Windows too for some users, though it's not nearly as bad as with DXVK. It's possible to mod the stage so that it looks the same but runs a lot faster. (60fps on 1920x1080 ultra settings on my GTX770 after updating DXVK to 1.1 and switching to a driver with VK_EXT_host_query_reset support! long as there are no bears on screen, and I either disable xfwm4's compositor or don't have too much stuff like web browsers open in the background)

I've posted instructions on reddit:

Not sure if it's ok to link the prebuilt pak file here since it's technically copyrighted material and I don't know where to host it anyway (mega and similar services probably aren't liked here?)

Also, apparently old Nvidia cards have really shite Vulkan support. Everybody says the 10xx and 20xx series (and AMD cards) would be a lot better in this regard, you'd get far less overhead vs. native D3D with them.

Now I just need a mod which changes the bears to look the same on high/ultra as they'd look on medium settings...

send a link for the pak
some reason AMD Works Flawless but Nvidia doesnt

Seems it's not possible for me to send you a private message (says your profile is private).

Well, here's the pak file (40MB), we'll see if the moderators allow it or not:!HVNXwQba!tmXIboDY6hIRzUIdtsXPH3G12ciWYY__kJCv1BwYQbU

Anyone can test it against GTA V (like fps, framedrops) ? Multiplayer is also playable with DXVK?

Grey area, I mean only people who own the game would be able to use it anyway right?
