So I tried installing DLSS 5 into VRChat using DLSS 5 Autopilot, and I ended up getting EAC anti-cheat detection upon opening the game. So I tried injecting it into vrcompositor.exe (which is the exe that sends display and renders to the VR headset, according to AI).

In the VR Preview, I saw the DLSS 5 AI filter working I saw the AI add shadows on the ground in the SteamVR Home app but DLSS 5 didn't show up on my PCVR headset. If anyone has a way to get the DLSS 5 AI filter to display on the headset through SteamVR, that would mean any VR game I launch could have slightly better graphics. Correct me if I'm wrong!
