RTX Features (There's LOTS)
Control represents the very best of what RTX has to offer, showcasing the entire Turing GPU package and the world NVIDIA is able to have on offer with its GeForce graphics cards mixed with the pure magic Remedy Entertainment has put into the Northlight engine.
- Ray-Traced Translucent Reflections: Control is the first game to feature ray-traced translucent reflections. Unlike screen space techniques which can only reflect what's on screen , ray-traced reflections incorporate the entire scene around the character, and can accurately represent objects outside the camera view, or facing away from the camera. Within the game, the reflections bounce off of opaque materials like brushed metal, but more importantly, off of translucent materials like windows so we can see what is behind the glass too.
- Ray-Traced Indirect Diffuse Lighting: "Indirect diffuse lighting" means light bouncing between non-glossy surfaces. When this indirect light is taken into account, you get a more realistic image on screen . Ray-traced indirect diffuse lighting in Control is composed of two parts: for nearby surfaces, we trace a ray to evaluate one bounce of real-time (dynamic) diffuse reflection. If no nearby surfaces are found, we use the ray information instead to sample pre-computed global illumination information at a more optimal location. The end result is that lighting feels more "natural" and objects "sit" better in the scene.
- Ray-Traced Contact Shadows: A hybrid technique where we trace shadow rays to add accurate shadowing on any surface that is close to the shadow caster. This enhances surface and contact details, and fixes problems associated with traditional shadow mapping techniques like aliasing, freckling and disconnected shadows. Further away from the shadow caster, we blend with traditional rasterized soft shadows using shadow maps.
