How to do Portal RTX modding?

[DEL∇]

With the recent portal rtx release, apparently one can use those nvida game dll files in this game to great affect. I tried looking up how it's done and the best I found was a wccftech article which mentions which files to drop in the game folder (heres the link to the article I looked at) [wccftech.com]

However, apparently Max Payne needs a special directX 8 wrapper for it to work, and the article mentions this. But I don't know how to set it up. I tried dropping in the files mentioned in the article and the dx8 wrapper and it doesn't work. I'm guessing I am missing a step or need to configure something. Does anyone know how I could use the nvidia portal rtx files to automatically enhance this game?

For background I can run this game relatively fine vanilla/unmodded on my computer. I have a laptop with windows 10, 9th gen intel i7, 16gb of ram and a rtx 2060. There's a little bit of wonky behavior with a few small things like when I launch this game the starting movie playing with no picture, the intro cutscene having no sound, and the comic book sequences playing without sound but the opening sequence of the game seems to run fine.

I can't figure out how to set this up to utilize the Portal RTX assets from nvidia, does anyone have any insight with this topic? I'd greatly appreciate any help

I haven't gotten my hands on the RTX files yet, but i read you have to rename some of them to avoid conflicts with the wrapper (they used cosire's wrapper) https://forum.beyond3d.com/threads/rtx-remix.62991/post-2279031

seems it works reasonably in indoor area's but the skybox is a problem and everything looks like polished marble ...

is working on it still as alot of the textures are really bugged if you just play it with the files.
he says he'll release it soon when everything is fixed so i would just wait

i've got the files now, but can't get it going.

this is what i tried (on w11):
https://www.reddit.com/r/linux_gaming/comments/zo75oo/max_payne_rtx_with_portalrtx_files_linux/
but as soon as i activate the dx8to9 fix it crashes (saying i need a directx 8 compatible display adapter), if i don't activate it, it just runs in dx8 mode and rtx-remix doesn't work at all of course.
also tried with cosire's wrapper, same thing.

guess we just have to wait for someone to tell us how they did it.

This is exactly what happened when I tried it: I copied the Portal RTX files into the game folder where the exe is, specifically the following files (.trex folder and the d3d9.dll, dxvk_d3d9.dll, and NvRemixBridge32.dll) and when I replaced the d3d9.dll with the dx8 wrapper and tried to start the game it'll immediately crash with that error. I wonder what is going wrong and what part is breaking

In any case, I greatly appreciate the responses and hopefully they'll be an actual application of the nvidia toolset to update this game. It's novel to see any kind of results by just copying assets so I wanted to see what it looks like firsthand

yea it went south after I changed =1 in scripts/global.ini even without replacing files, just using both d3d9 and d3d8 dll's in main directory. the 'funny' thing is when this is set to 0 and you start it, not only does the game start, but looking at the d3d9.log and NvRemixBridge.log it looks like it all worked out okay, no errors there...

rtss indicates dx8 however and fps goes through the roof, so it obviously doesn't do dx9. (i can ofc. limit this with rtss) also tried it without rtss active, but same result.

tried renaming the widescreen fix's d3d8.dll to dinput.dll (thinking maybe the rtx mod would try to insert a similar named file?) that way widescreen still loads, but UseD3D8to9 doesn't work.

for the other points you mentioned:
white movie: for now just disabled it by renaming the movie to some other name, seems to be an issue lately, i suspect it's a nvidia driver issue.
no sound: used the dsoal files and the reg fix. indirectsound tested too
jpeg errors: the new cpu aka ryzen fix was needed on my 13600k
