Adapter: NVIDIA RTX2070
Driver: 515.49.15
OS: Ubuntu 20.04
Proton version: GE-Proton-7.31
Run settings: PROTON_LOG=1 PROTON_ENABLE_NVAPI=1 %command%

Enable DLSS + set options in the "launcher" window.
Steam log attached: steam_default.zip
Error: err:d3d12_command_signature_init_state_template: Root parameter 26 is not a raw VA. Cannot implement command signature which updates root descriptor.

Possible cause: When using PROTON_ENABLE_NVAPI=1 the option DXVK_ENABLE_NVAPI=1 is automagically set by the proton script, and maybe vkd3d runs a slightly different codepath when not being fooled into AMD mode?

Simple quick-fix to that:
Add this

        #if PROTON_ENABLE_NVAPI is set for NVIDIA adapter using vkd3d for Guardians of the Galaxy it will fail.
        if "SteamAppId" in os.environ:
            appid = os.environ["SteamAppId"]
            if os.environ["SteamAppId"] == "1088850":
                self.env["DXVK_ENABLE_NVAPI"] = "0"

below the lines that read

        if "enablenvapi" in self.compat_config:
            self.env["DXVK_ENABLE_NVAPI"] = "1"

in the proton script. This lets you start GotG without using DXVK_ENABLE_NVAPI=1 and it goes further. PS. You can no longer select DLSS in the launcher settings when doing that tho, but settings are saved from previous run.

Hmpf.. memory allocation error of sorts.

Reverted this PR https://github.com/HansKristian-Work/vkd3d-proton/pull/1147 , and yay.. a success!

Any chance this could be looked at?

VKD3D_CONFIG=force_raw_va_cbv should fix the first error message you quoted, however this will likely come at a significant performance cost. There's nothing we can do about that though, it is not possible to support the Nvidia fast path and complex ExecuteIndirect at the same time.

I'm having a hard time following the rest of your report (why exactly are we messing around with the Proton launch script?), not entirely sure what you're trying to tell us there.

As for the memory error, we're aware that linear memory allocations are currently broken and it is planned to rewrite this at some point, but I don't know why it would outright fail on your system. It really shouldn't, and it doesn't on my system.

Sorry, i forgot to mention i already tried that, and the image is distorted (black flickering triangles even tho the menus work) as i mention here: https://github.com/HansKristian-Work/vkd3d-proton/issues/1169#issuecomment-1207385218

The game started if i use VKD3D_CONFIG=force_raw_va_cbv with DXVK_ENABLE_NVAPI=1, but image was distorted and flickering (although menu could be used).

I'm having a hard time following the rest of your report (why exactly are we messing around with the Proton launch script?), not entirely sure what you're trying to tell us there.

The reason for messing with the proton script is because if i do not do that, i have to use VKD3D_CONFIG=force_raw_va_cbv and the image is distorted and useless. "messing" with the proton script bypasses this by NOT setting DXVK_ENABLE_NVAPI=1 and thus bypassing this issue it seems. (Different codepath used for vkd3d?)

Sorry that i forgot to mention the earlier post in the closed thread, and that this hopefully explain the reasoning why force_raw_va_cbv did not work (for me).

As for the memory error, we're aware that linear memory allocations are currently broken and it is planned to rewrite this at some point, but I don't know why it would outright fail on your system. It really shouldn't, and it doesn't on my system.

I do not know what would be broken on my system. Perhaps some distro differences? Kernel? System settings? (Not using any particular settings that i am aware of that would change default steam proton settings, but i might need some perhaps?)

Short update on Guardians of the Galaxy on NVIDIA (Ampere, 530.41.03) with vkd3d-proton https://github.com/HansKristian-Work/vkd3d-proton/commit/f52e6482bc63d907054025c5eaf8c0d71a7a9f28:

  • Game runs normal when spoofing AMD.
  • Games needs force_raw_va_cbv to avoid startup crash (to avoid Root parameter 26 is not a raw VA....) when NVIDIA is visible, but when being in the menu and in-game it looks like vertex/geometry explosions/flickering all over the place (I have no better description, its probably something else) , but menu/interface is visible and e.g. benchmark can be started and finishes. PR https://github.com/HansKristian-Work/vkd3d-proton/pull/1147 mentioned similar symptoms (as far as I can judge) and fixes that for AMD.
  • DLSS/nvapi shows nothing unusual, DLSS starts and seems to work.
  • When exposing dxr, the game crashes during startup on the 530 driver, because the driver doesn't has VK_EXT_pipeline_library_group_handles yet (at least the last fixme in vkd3d logs indicates this https://github.com/HansKristian-Work/vkd3d-proton/blob/master/libs/vkd3d/raytracing_pipeline.c#L262) ~I don't know what happens when that extension is present.~

This is essentially still the same status as described above.

Jjp7677 2023-06-11 github

The easiest work around for still having DLSS in this game is the following:

  • Enable NVAPI for this game (e.g. PROTON_ENABLE_NVAPI=1)
  • Enable DLSS in the launcher
  • Quit the launcher
  • Place a dxvk.conf containing dxgi.customVendorId = 1002 next to gotg.exe for spoofing AMD
  • Start and enjoy the game! It now uses the AMD path which works fine with an NVIDIA GPU and surprisingly still enables DLSS!

Note, this requires https://github.com/jp7677/dxvk-nvapi/commit/a2235c8c7510a6a53938be053482b32b6658b210

@SveSop no need to hack the proton script ;)

PS: Unfortunately the launcher is the same executable as the game itself, so we cannot create an application profile to implement this work around more elegantly.

Jjp7677 2023-06-17 github

About the ray tracing features, those can be enabled and do work when using the NVIDIA 535 driver and Proton Experimental Bleeding Edge i.c.w. exposing VKD3D dxr option. Proton Bleeding Edge is (currently) needed because it ships an update winevulkan that reports VK_EXT_pipeline_library_group_handles when the driver knows this extension.

The RT features are available when spoofing AMD and also when exposing NVIDIA (needs dxr,force_raw_va_cbv), but the explosions/flickering is obviously still there with the NVIDIA path. Note though that the DLSS trick from the former posting prevents RT from being enabled, so when spoofing AMD it is either enjoying DLSS (by enabling NVAPI) or enjoying RT (by not enabling NVAPI), but not both.

@runar-work Can you test this game with VKD3D_CONFIG=force_raw_va_cbv and DXVK_ENABLE_NVAPI=1 on recent NV drivers?

Rrunar-work 2024-01-05 github

Tested with RTX 4070 and 545.29.6, and any attempts I made to skip AMD spoofing lead to massive vertex explosions, so seems there's still no way to get both DLSS and RT.

Sshelterx 2024-03-12 github

Still does the same thing on 550.40.55, lot's of vertex explosions.
So NVAPI needs to be disabled. which it is by default in Proton 9 for GOTG.

Sshelterx 2024-09-27 github

I guess this game will never work with NVAPI and DLSS and RT combined?
Even if the vertex explosions go way the performance drop isn't going to be fun.

Sidenote, there's a slight FPS increase in this game with dev 550.40.75 with RT on. Which's good I guess, let's hope it stays that way.

Sshelterx 2025-01-30 github

Woah, DLSS works with driver 570.86.16 and VKD3D_CONFIG=force_raw_va_cbv
The vertex explosions are gone.... Without DLSS the FPS is ~90 in the main menu

Yep.. latest driver 570.86.16 + DLSS 310.2.1 + VKD3D_CONFIG=force_raw_va_cbv seems to run the benchmark about the same FPS as i get in windows with "Ultra" preset + Raytracing and DLSS enabled.

Using proton 1738342890 experimental-bleeding-edge-9.0-157790-20250131-p09ed8f-w23f5e7-d8776cf-vde2987 you need to edit the proton script with this:
# "1088850", #Marvel's Guardians of the Galaxy

Huge upgrade it seems 👍
Have not played a lengthy time, so it could possibly be prone to crashing at certain spots.. dunno.

No need to edit the proton script, just forcing nvapi does the trick as well: VKD3D_CONFIG=force_raw_va_cbv PROTON_FORCE_NVAPI=1 %command%
