    Without Async unless someone modify necessary files to include it ;-)

    I already use this of course on Linux through Steam Play, but I just tried this on Windows 10 in GTA 4. People online say it improves the game's performance a ton on Windows.

    Well, for me it cuts performance almost in half. With uncapped FPS, I go from 90-100FPS to 50-60FPS. With capped FPS (60), GPU utilization goes from 50-60% to 90-100% and the game is often struggling to maintain 60FPS. It dips to the 50s or high 40s very often.

    Tried both vanilla DXVK as well as DXVK Async (1.7.3.) This is on a 980 Ti at 1440p.

    Two other issues with DXVK are that the game thinks I only have 512MB of VRAM so it disables the high graphics settings, so I have to set:

    -availablevidmem 6144

    in the Steam launch options to tell the game I have 6GB. The other issue is that I cannot select 1440p anymore in the game. Max resolution is somewhere around 720p. This can be fixed by using this in dxvk.conf:

    d3d9.forceAspectRatio = 16:9

    I wish there was also a fix for the atrocious performance loss :p If I could get it to work as well as it seems to be working for other people, I might be able to use DSR to get some proper anti-aliasing and still get a solid 60FPS.

    An extreme performance hit when GPU bound is not that uncommon with Nvidia, e.g. HotS also runs ~50% faster without DXVK on Pascal.
    Can be due to not available nvapi optimizations or driver + hardware limitations. Though there usually is far less need to use DXVK with Nvidia in the first place (at least on Windows).

    I didn't change anything for GTA4, seems like user error, especially since the correct setup for gta4 on cards >1GB requires a commandline.txt file.

    Actually, no, you're right, my configuration was being pulled from the games pre-dvxk setup so it was setting 1440p but the bar was longer than it should be and when you moved it down you lost the ability to set above 1280x720.

    The issue is the amount of modes reported is higher than the game can actually list unless you clamp it to only displaying 16:9 modes, for some reason its not even limiting it to what the monitor reports as supported. heh.

    Mirror's Edge Catalyst actually works on Windows when disabling fullscreen optimizations, though AMD's proprietary Vulkan shader compiler produces garbled screen space reflections (and is also slower in this game vs. RADV ACO).

    There is no nightly build available for every new commit. What we need is to include async patch with latest dxvk commit.
    Hoping that some linux gurus can do it here :)?

    I'm unfortunately not a Linux guru who could set up auto-generated and auto-hosted nightly builds. DXVK is easy to build though and there is this toolset to conveniently apply patches: https://github.com/Frogging-Family/dxvk-tools
    If the patch requires rebasing with newer git-master commits at some point, it would probably require the patch developer's attention anyway. But perhaps the next DXVK release isn't that far away and the maintainer of the patch will provide a new build?

    Nice, wasn't expecting it to be available that quickly. Excellent.

    So people, from your experience, what other games benefits tremendously from DXVK on Windows?

    Currently playing Jedi Fallen Order and the experience is noticeably smoother. Smoother frametimes, slightly less CPU bound and vastly fewer stutters.

    There are other pages in this thread with what you are looking for.

    Quantum Break does not like DXVK. Some 3-7 fps less than DX11 and stuttery at the beggining, even with DXVK Async. Oh well.
