GPU fake name should be injected with dll

[jskake]

So apparently we have list of games that also check your GPU name in adddtion. Dying Light 2, Portal RTX, Atomic Heart. Since no method is working we can assume that game also check your GPU name and it should be RTX 4000 to make FG option available. For example Dying Light 2 - if you don't have RTX 4000 GPU - you will not even see the option of FG in the menu, much less to activate it. Checked all current methods from other FG games - no dice here. My proposal is somehow substitute GPU name and inject it via dll to make the game thinks that we have an RTX 4000 GPU.

Why?

For Portal RTX it doesn't matter, it's a DXVK game. The mod doesn't work with Vulkan. The author of this mod already said implementing FSR3 for Vulkan or whatever is beyond the scope of this mod and his resources that he's willing to dedicate to the project.

Besides, FSR 3 FG Doesn't even work on Vulkan yet.

It would certainly help in those games where the FG option isn't even visible unless there's a 4xxx series card..

Try using this https://github.com/FakeMichau/nvapi-dummy

I dont think its just name check.. I compiled and tried that nvapi-dummy it didnt worked.

I think the way to go would be hooking the directx getdevicename and getadaptername. (Not fully sure)

This on will work:

Fakes card to RTX 4090.

Didn't work.. Benchmark shows 4090, but still no FG option

[peter1599]

Ye I see.

The logs show RTX 4090

But:

Still returns false.

Anybody tried modding GPU driver INF-file to spoof RTX 40 series card on driver level?

If anyone interested finding out how they check dlssg support:

rd3d12_x64_rwdi.dll is the right file.

I'm currently trying to find how its happening but I only know basic stuffs.

[peter1599]

HMM... Progress:

Needs more testing.

How??

[peter1599]

Modifying dll but only option is unlocked its not yet turning on FG.

Good progress anyway!

[peter1599]

Got a tiny bit further but still frame gen not working.

Now even game logs say:

If anyone wants to help I would appreciate it 😃

Any development on this?

This is not something that should be considered with dlssg-to-fsr3 since basically no games check for your GPU's Name in order to verify if DLSSG is supported. You can read DLSSG Implementation guides here: https://github.com/NVIDIAGameWorks/Streamline/blob/main/docs/ProgrammingGuideDLSS_G.md

If you still persist on forging your GPU's name for an application, I recommend https://github.com/cdozdil/d3d12-proxy.
