How do you actually install DLSS Enabler / MFGx4 mods? I’m confused af

I downloaded MFGX4 for NVIDIA from Nexus Mods, and inside the folder there are only 3 files:

• dlss_to_fsr3
• dlss_to_fsr3 3.0
• version.dll

What I’m confused about is:

Am I literally just supposed to drag all 3 of those into the game’s bin64 / main executable folder?
Or is there something else I’m supposed to do before or after that?

Also, in a lot of the tutorial videos, they have some kind of separate blue in-game menu / overlay thing, and I don’t have that at all, so I’m even more confused.

I’m guessing those tutorials are probably too advanced / not really made for people who are just starting out with this whole frame gen modding thing, because I genuinely still don’t understand the basic install part 😭

I’m scared that if I just do it myself without asking here, I’ll end up breaking my game and having to reinstall 140gb worth of Crimson Desert again...

If anyone can explain it to me in simple idiot terms / step-by-step, I’d really appreciate it.
