DLSS Swapper creator warns users about malware-infected DLL files

The creator of DLSS Swapper — a widely-used tool that lets you swap NVIDIA DLSS versions in games to test performance or fix bugs — posted a security warning yesterday. Users who download random DLL files from untrusted sources risk installing malware, according to the developer's statement on the project's GitHub page.

DLSS Swapper itself is safe when downloaded from the official repository. The risk comes from third-party DLL files shared on forums, Discord servers, or modding sites. These files replace the DLSS libraries that games ship with, which means a malicious DLL has kernel-level access to your system. Bad actors can embed keyloggers, ransomware, or crypto miners in these files. The tool can't validate what's inside a user-submitted DLL before it swaps it in.

The developer recommends sticking to official NVIDIA DLSS releases or files from verified sources like TechPowerUp's DLSS archive. If you've already installed DLLs from random forum posts, run a full antivirus scan and check Task Manager for unknown processes eating CPU cycles in the background.

This is a good reminder that modding tools are only as safe as the files you feed them. DLSS Swapper makes version-swapping easy, but it can't protect you from sketchy downloads. If a 50fps boost sounds too good to be true and the source is "some guy on Reddit," it probably is.
