Models not rendering during Remix runtime

[Speedwagen]

This happens because DXVK does not know how to interperate a specific format.
"warn: ConvertFormat: Unknown format encountered: D3D9Format::AL16
warn: ConvertFormat: Unknown format encountered: D3D9Format::R16"
According to this change in the main DXVK Build - doitsujin/dxvk@c13395d
[util] Enable strict float emulation for a bunch of games
doitsujin/dxvk#2107

Changing the d3d9.floatemulation to strict will cause the grass to render.

I was experiencing this issue in Arx Fatalis. Key objects where not being rendering during the the RTX Runtime.

I miss read this and the issues displayed are actually related to the D3D9: VK_FORMAT_D24_UNORM_S8_UINT -> VK_FORMAT_D32_SFLOAT_S8_UINT and not specifically the the texture formats.

found a potential solution.

doitsujin/dxvk#1661
misyltoad/d9vk#155 (comment)

which involved adding the format to d3d9_format.cpp.
Ran a build and now I am being presented with memory allocation failures.
arx_d3d9.log

Not sure if the implementation is accuate or not.
Attached the Log for now.

This fix did not work. The error messages disappeared but the models were still not showing up.
I found that this issue was reported back in 2005 -
**(2) "all interactive objects-- NPCs, the PC, stones, inventory items, creatures, etc -- are completely invisible. This also seems to effect the game in other ways; for example I cannot select an object, such as a door, that's invisible, although I do collide with it."

This has been reported with a GeForce 5200 FX video card and DirectX 9.0c, and was fixed by using the Forceware 61.77 drivers.**

There should be bars where the circle is.

If need be I can supply a trace file.

[Speedwagen]

I should also clarify that I am using Arx Libertatis 1.1.3 and running the 64bit executable.
If the game is running in windowed then the raytracing will not work.

[Speedwagen]

after troubleshooting I have found that the objects not being rendered are due to the objects being in another render target.

info: [RTX-Compatibility-Info] Trying to raytrace but not detecting a valid camera.

The following warning is showing even though path tracing is working.
