This is made by NV Lightspeed Studios, not Valve, using the RTX Remix toolset.Every frame of gameplay is upgraded with stunning full ray tracing, new, hand-crafted hi-res physically based textures, and new, enhanced high-poly models evocative of the originals, all in stunning 4K.
Modders can basically use this tool for any game to achieve similar results. Would be fascinating to see what the community comes up with.
