With Hitman 3, I am guessing you enabled Ray Tracing in the launcher options, clicked save then launched the game with those settings?

Did you check the graphics settings in the ingame options to see if you can enable ray tracing there? With 6700xt/11600K, git pull of VKD3D from last night and Mesa 22.2 Devel, I can enable ray tracing in the launch options area but ingame, the option is disabled. It appears that not everything is ready for ray tracing in Hitman 3 under linux just yet...

I'm having issues with RT in Hitman 3 as well. I can enable it and DLSS in the launcher (VKD3D_CONFIG=dxr DXVK_FEATURE_LEVEL=12_1 etc. in env variables) and the frame rate absolutely tanks so, something is happening - but RT reflections aren't displaying (I honestly can't tell if lighting/shadows/etc are working, the frame rate stabalises when reflections are turned off and I'm not sure what to make of that?). Cyberpunk 2077 RT is working with the same set-up. Like jhu54 above the settings are disabled in-game, I'm not sure if this is normal as I don't run Windows anymore to test.

• RTX 3060Ti/Ryzen 5 3-series
• Arch Linux
• nVidia 515 drivers
• Latest Wine-GE via Heroic Launcher
• rt-subobject-association branch of vkd3d (this branch made a huge difference in being able to enable and use RT in Cyberpunk)
• DXVK NVAPI DLL

I'm going to download the demo of the Steam version and see if Proton-GE gives me a different result

You're right, I enabled it in the launcher settings, ingame I can't change it (the RT options are greyed out) but they say they're enabled...

there were a bunch of rt related changes that got merged 2 days ago, maybe try this again?

No dice here :( Same result as before

In my case (RTX 3080 Ti) the option in the launcher is greyed out. The game does detect the right GPU, and I'm using this as launcher options:

VKD3D_CONFIG=dxr11 DXVK_FEATURE_LEVEL=12_1 PROTON_ENABLE_NVAPI=1 PROTON_HIDE_NVIDIA_GPU=0 %command%

Any ideas?

Update

It works now with the variables above and Glorious Egg Proton-6.21-GE-2

Tried with VKD3D_CONFIG=dxr11 RADV_PERFTEST=rt DXVK_FEATURE_LEVEL=12_1, In the launcher i could enable ray tracing but in game it showed that only ray tracing was enabled (Ray traced Sun Shadows and reflections were off, and the options were greyed out)

RX 6950xt, R7 5800X

Same results here as JonLit, RT ON, but can't change settings in game, and no visual change or FPS drop

I am experiencing same issues with Resident Evil RE engine based games too.

Toyed a bit around with this (Hitman 3 RT) and it doesn't seem to be a vkd3d-proton issue. I can enable RT fine ingame on Windows with vkd3d-proton when i also give it a bogus vendorId e.g. dxgi.customVendorId = ffff which you would put into a dxvk.conf file next to the exe ( HITMAN 3/Retail/ ). Tested with a 7900XTX.
This also works on Linux if i do the same thing.

I am unsure what info it is looking for without this workaround that doesn't fulfills it's requirements for AMD since setting amd_ags_x64 to native doesn't help. Windows Driver version reported through there is relatively up to date.

If I just set that in the dxvk conf it works? Do I need anything else in that file? Any command line ARGS needed?

Well works and works. My GPU hung and second time game black screened on loading, but it allows me to enable the options ingame.

I dunno what GPU you have. If you have amd and use radv driver you'd need VKD3D_CONFIG=dxr11 RADV_PERFTEST=rt %command%
For Nvidia just VKD3D_CONFIG=dxr11 %command%
Unsure if Nvapi needs to be enabled on Nvidia for RT even if we report another GPU vendor.

Edit: Also get a crash if i start the game with RT already turned on before main menu.
Also i missed your comment above. See you have AMD now

Just ran across this issue when trying to get RT working in the demo version. Simply having RT features enabled for vkd3d leaves the RT option in-game greyed out, but setting a bogus vendor id as suggested by @Blisto91 changes that. With the workaround in place both RT reflections and shadows can be toggled in game and render correctly. Of course, that means losing access to DLSS.

4070 Ti, driver 535.86.05
Nobara 38, kernel 6.3.12
GE-Proton8-9

RT is still broken with the dummy vendor ID, now when i open the game i get a vkCreateRayTracingPipelinesKHR error
(RX 6950XT)

when i open the game i get a vkCreateRayTracingPipelinesKHR error
(RX 6950XT)

This is probably a RADV issue. In current stable Mesa versions (up to 23.1.x) that is sort of to be expected. These issues should be gone in 23.2, but that isn't released yet as of now. Best thing is probably to wait until 23.2 is out (shouldn't be too long until it is released) and then try again.

same issue with 23.3.0

Post a log

I'm having a related issue where the Ray Tracing option is just greyed out for me. I'm on Fedora 38, I have an RTX 2070s, and ray tracing works in other titles just fine. I've tried the latest Proton, Experimental, and GE 8-13, along with every combo of these launch options: PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 VKD3D_CONFIG=dxr DXVK_FEATURE_LEVEL=12_1 gamemoderun %command%

I have enabled DLSS and that was no problem, so one of the Nvidia features is working.

It just won't let me enable it in the launcher or in the game menu.

That is literally this whole issue in a nutshell. Welcome to the club.

dxgi.customVendorId = ffff

VKD3D_CONFIG=dxr11 gamemoderun %command% -skip_launcher

Ray tracing works fine (no artifact) but incredible drop performance (75 to 5 fps) but i suppose is normal with my gpu

Interesting, maybe my issue is 6xxx only, I can't even open the game with RT enabled

@davigamer987 mesa version ? (23.2 is the first that enable RT for RADV)

Can you post a proton or wine log please

Can AMD users verify that the Ray Tracing option ingame is no longer grayed out without a override on Proton Experimental Bleeding Edge? (mesa 23.2.1+). No vkd3d-proton configs should be needed either.

If Nvidia users could give it a recheck that would also be great.

Still greyed out, even when passing VKD3D_CONFIG=dxr

On the upside, DLSS now works instead of turning the whole screen bright yellow

Ray tracing is no longer grayed out for me. Ray tracing, ray traced reflections, and sun shadows can be toggled. No commands in the Steam launcher. I have AMD 7900 XTX and 7800 XT cards and Mesa 23.2.1.

If we're talking VKD3D 2.11, DLSS works but RT is still grayed out. 3060ti.

I have the same problem and i have the RTX 4070 :/, anyone solution?

No the cause is not known yet. Pretty sure it isn't a vkd3d-proton issue though

With nvidia GPUs, DXVK_CONFIG="dxgi.customVendorId = ffff" indeed enables RT and makes RT works in game. DLSS though, even if configurable, does not seem to change anything, as I'm getting the same performances/image quality in Quality or Performance mode.

This should now also work with Nvidia on Proton Bleeding Edge without any workarounds.

Edit: see nvapi PR below for info

Thanks, although for me the Ray Tracing option is still greyed out on Proton Experimental. My GPU is a RTX 3080 Ti. I tried both with

VKD3D_CONFIG=dxr11 DXVK_FEATURE_LEVEL=12_1 PROTON_ENABLE_NVAPI=1 PROTON_HIDE_NVIDIA_GPU=0 %command%

and also without it, in both cases it is greyed out.

It isn't in Experimental yet. Only the Experimental Bleeding Edge beta branch

I confirm that this works (enabling RTX + DLSS in Hitman 3) by building https://github.com/GloriousEggroll/proton-ge-custom by hand with https://github.com/jp7677/dxvk-nvapi/commit/42ec75b470ba6aa9b8c078f5528f59832920f7c4 for dxvk-nvapi. Indeed, unfortunately, the latest Proton-GE has been built one day before that patch landed in dxvk-nvapi... I guess the next Proton-GE official release should just work.

You also need NVIDIA driver >= 550.54.14 to prevent XID CTX SWITCH TIMEOUT errors.

Thanks @jp7677 for the fix!

Is included with the new Proton 9 Experimental

Yep, I can confirm it works now with experimental. It's great!

I can see it with proton experimental, but I'm not sure it's working properly. I have a 3080 and can otherwise put every setting at max and stay at a completely locked 120hz, but the second I turn on any ray tracing my performance dips to around the 40s.

Obviously ray tracing is a fairly costly thing to enable, but given that the 30 series was released just a few months before Hitman 3 was and I'm playing at 1080p I don't think Ray Tracing should be over halving my frame rate like that. The only time I've ever had an FPS drop quite this drastic was with Ghostrunner and it was an issue with the game itself that was fixed by installing some of the updates. (IIRC I got it on GOG or something and whateverl auncher I was using didn't auto-install the updates)

I'm by no means a graphics pipeline expert, but locked 120fps with everything on absolute max taken down to 40fps with medium-high settings seems like it's more likely to be an issue than not. Can someone else check and see what performance they get with it enabled because a drop that drastic doesn't feel right to me.
