![]() Above, left to right you can see that RT Ambient Occlusion isn't going to cause much strain on a GPU, while Global Illumination relies on considerably more intense calculations. It is also clearly explained that various types of raytracing loads come with varying performance penalties. The best case is seen in the bottom row where the RTX 2080 RT cores are put to task, massively accelerating this rendering task. Moving down to the next row you can see that an RTX 2080 which can execute floating point and integer instructions (purple) simultaneously. ![]() You can see it takes up a lot of frame rending time - about 80 per cent of the time used. ![]() Nvidia's Tech Marketing VP has highlighted the GTX 1080 Ti SM processing of raytracing imagery with a green box. ![]() See the explainer video featuring Tamasi embedded below.Ībove you will see Mr Tamasi explain that some raytraced games effects will work acceptably on the more powerful Pascal cards - but in the newest and more demanding titles such as Metro Exodus GTX 10 and GTX 16 graphics card owners should probably only turn on raytracing for a quick look at the eye candy they are missing.Ī processing example of a single Metro Exodus frame is provided in the image above. In other words, Nvidia VP of Technical Marketing, Tony Tamasi, says "even folks that have Pascal, if they just want to check it out, they can at least see what raytracing looks like and get a little taste for themselves". However, one must remember that with their dedicated RT cores, the GeForce RTX 20 range provide up to 2-3x faster performance in raytraced games, facilitating more effects, higher ray counts, and higher resolutions. With the new driver installed "millions more gamers with GeForce GTX GPUs to experience ray tracing for the first time ever," says Nvidia. Thanks to this new driver there are now "tens of millions of DXR GPUs" in consumer PCs. It is called the GeForce Game Ready Driver version 425.31 WHQL and is available immediately. Today the driver enabling real-time raytracing on the GTX 1060 6GB and better has been released. ![]() Back at the GDC 2019 in mid-March, Nvidia CEO Jensen Huang revealed that real-time raytracing technology was about to become available to a lot more Nvidia GPU owners in the coming weeks. ![]()
