Simulation of light paths in 3D scenes
So umm... I will be completely honest, I am totally new to this whole ray tracing stuff and while the little of what I could see in trailers and some basic info on the web did make me smarter, I still cannot answer this one for myself. Can the ray tracing tech be included backwards in the current triple A games, or do we have to wait for new engines and games build aro und this feature? As in, should I hold my breath to see I don't know, FFXV for example, getting an update, which will allow it to use the ray tracing cores on new TRX series, or will I have to wait for newer games to show up with the tech already included from the get to?
Several titles might be adapted for this purpose, but as consumer access expands, it’s likely newer games will be developed with these tools in mind.
Games must receive its code updated to enable ray tracing support. Implementing ray tracing in software isn't a quick fix; DirectX 12 provides some assistance. I haven't verified whether Nvidia or Vulkan have made changes, but it seems possible. The positive side is that updates can be applied without a complete overhaul of the game. Still, developers and publishers need to be interested—especially if they believe it won't hurt current sales or if major companies like Nvidia or Microsoft aren't willing to invest. It might appear in future releases.
The current setup shows some polygons being processed with ray tracing instead of fragment shaders. This isn’t a full redesign of the graphics pipeline, but rather an additional post-processing stage that can be integrated smoothly. It works well as a separate effect that can be applied to existing engines without major changes. However, I doubt it will appear in many current games since there’s little financial motivation for such an upgrade. Be cautious of the excitement around it—rasterization usually performs comparably and is much faster.
Sure, we need the architecture specifics to understand. It seems to rely on float point support with specialized hardware for certain tasks. The drawback is that this leads to more powerful GPUs and larger chips. This is similar to what happens with float point support in processors, which is widely used despite its drawbacks. For ray tracing, while it will likely become faster and smoother over time, current games require full support to meet performance needs. Ray tracing isn't a simple one-time operation like basic lighting; it demands more complex handling. Most indie developers probably won’t adopt it, except for major titles focused on cinematic visuals, such as Call of Duty. Nintendo’s style, on the other hand, seems less suited for ray tracing improvements.
It's a blend of traditional ray tracing and AI-enhanced techniques. While basic rendering is handled with standard ray tracing, AI is used to fill gaps and optimize performance. You'd need backward compatibility to maintain smooth operation. Over time, more powerful GPUs will allow higher ray counts, improving image quality and possibly adding sliders for custom settings. Currently, most visual effects rely on texture work rather than complex shaders, though hardware advancements are shifting that trend. Techniques like bump mapping use subtle texture adjustments—adjusting brightness and contrast per pixel based on lighting—to simulate depth without heavy geometry. This approach is more efficient than creating large polygon counts, offering realistic results when combined with skilled artists and programmers.
