Description
Describe the bug
Turning on DLSS Ray Reconstruction (doesn't matter CNN of Transformer) makes reflections worse
When RR is off: Perfect reflections
When RR is on, there are blurriness, ghosting + artifacts
Also, when RR is off, reflections on glass ("convert to translucent" material in toolkit) are nice - reflects only bright areas like sky, while turning RR On makes glass reflect more sources and surfaces which looks less realistic
and also, there is weird sharpening effect when RR is in CNN mode.

Garry's Mod RTX

Ray Reconstruction on other games like Cyberpunk 2077 makes reflections sharper and clear, while in Remix... It makes opposite

Research direction
Reproduce the issue in Garry's Mod RTX using the gm_construct_rtx map and compare reflections with DLSS Ray Reconstruction enabled and disabled in CNN and Transformer modes. Review the linked video and screenshots for the reported blur, ghosting, artifacts, glass reflections, and sharpening; done means identifying and correcting the rendering behavior without degrading reflections.
