NVIDIA unveiled RTX Remix, a platform to help modders remaster games, and add ray tracing features to DirectX 8 and 9 games. Using this tool, modders can significantly improve the textures and lighting effects of older games. Classic games could also benefit from NVIDIA DLSS (deep learning super sampling).A game mod created using NVIDIA RTX Remix will essentially replace a game's original API with a 64-bit Vulkan renderer. Modders can easily export their RTX Remix mods into files and then drag and drop them into a game's directory alongside the executable. NVIDIA assures these new RTX mods shouldn't conflict with those from Nexus Mods or other sites.
