DLSS4 MFG 4x not working in stalker 2

[DevonX]

Hello i am trying to set up DLSSFG in stalker 2 but for some reason it does not seem to go over 2x even with the override. Here is my settings that i am using.

Variables used:
PROTON_ENABLE_NGX_UPDATER=1 DXVK_NVAPI_DRS_SETTINGS=NGX_DLSS_RR_OVERRIDE=on,NGX_DLSS_SR_OVERRIDE=on,NGX_DLSS_FG_OVERRIDE=on,NGX_DLSS_RR_OVERRIDE_RENDER_PRESET_SELECTION=render_preset_latest,NGX_DLSS_SR_OVERRIDE_RENDER_PRESET_SELECTION=render_preset_latest,ngx_dlssg_multi_frame_count=3 DXVK_NVAPI_GPU_ARC=GB200 PROTON_USE_NTSYNC=1 PROTON_ENABLE_WAYLAND=1 DXVK_HDR=1 ENABLE_HDR_WSI=1 mangohud DXVK_NVAPI_SET_NGX_DEBUG_OPTIONS=DLSSIndicator=1024,DLSSGIndicator=2 %command% -consolekey=F10

System information:
GPU: Nvidia RTX 5090

There is probably not much we can do here. Assuming that you succeeded to use those launch arguments with other titles, this is out of our hands. We just pass those settings to the game, if the game requests those, and then it is up to the game/middleware (streamline) to use them or ignore them. If you figure how to produce an DXVK-NVAPI log file, you should see entries indicating which settings have been requested.

For producing a log file:

• When using Proton, set the Steam launch options for your game to DXVK_NVAPI_LOG_PATH=/tmp/ DXVK_NVAPI_LOG_LEVEL=info %command% and attach the corresponding nvapi.log/nvapi64.log/nvofapi64.log file found in your /tmp/ directory.
• See Tweaks, debugging and troubleshooting for general information.

Here is the log file.

Thanks.

1248.463:0158:015c:info:nvapi64:<-NvAPI_DRS_GetSetting (0x104d6667/Override DLSSG multi-frame count = 0x3): OK

So the setting is correctly applied and the game/streamline has picked it up. So DXVK-NVAPI did its job. But unfortunately no idea what other requirement is missing. I’ve seen this on other titles as well, sometimes custom MFG count gets applied (CP2077 or Indiana Jones and the great circle) or sometimes not (Ghost of Tsushima from what I remember).

This issue might contain #317 related info.

Is there anything else i can do to help with this issue? some kind of debug information or steps i can take to test things out?

not sure what IJ is but a guess that i got is that it might have to do with unreal engine maybe? i think there is some console commands that i could try with is general with unreal engine to force a higher FG. just need to find those commands.

Sorry, that was a bad shortcut for Indiana Jones (and the great circle) ;)

I'm not familiar with the internals of Unreal Engine and its interaction with Streamline, I don't know unfortunately.
