NVIDIA is still committed to sprucing up Quake II RTX's graphics after the novelty has worn off. The GPU maker has released a 1.2 update that adds significant realism to the ray tracing effects -- insofar as you can have realism in a sci-fi game, anyway. Water is now considerably more realistic, with "god rays" that are visible even in reflections and refractions. Many textures have been updated to look sharper or just plain better. Glass is also considerably more realistic, including more "god rays," tinted glass and an experimental option that calculates the reflection and refraction inside thicker glass.
