The pilot announced by Nvidia to GDC in mid-March, which also provides the GeForce GTX with Pascal and Turing Raytracing, is now available as GeForce 425.31. And with new technical demonstrations on Atomic Heart and Justice, as well as the demonstration of the Star Wars Elevator demo, Nvidia is also promising more test software.
New graphics cards with "RTX support"
Until now, only GeForce RTX graphics cards with their RT cores dominate the Turing TU102, TU104 and TU106 GPUs. GeForce GTX models based on the Turing TU116, which does not offer RT cores, as well as most GeForce GTX based on Pascal GPUs, are now available. Specifically, the following graphics cards are affected:
- GeForce GTX 1660 Ti (TU116 without core RT)
- GeForce GTX 1660 (TU116 without RT cores)
- Titan Xp (GP102)
- Titan X (GP102)
- GeForce GTX 1080 Ti (GP102)
- GeForce GTX 1080 (GP104)
- GeForce GTX 1070 Ti (GP104)
- GeForce GTX 1070 (GP104)
- GeForce GTX 1060 6GB (GP106)
Equivalent mobile graphics cards are also supported. Thus, only the GeForce GTX 1050 (Ti) with GP107, the GeForce GT 1030 with GP108 and the 3GB version of the GeForce GTX 1060 with GP106 are absent from the Pascal generation.
Two new technologies and the Star Wars Elevator demo
The new driver will not be released today. In addition to the games already available with Raytracing, Battlefield V, Metro Exodus, Shadow of the Tomb Raider and the Port Royal test sequence of 3DMark appear, according to Nvidia, three other applications with raytracing. On the one hand, the Star Wars Elevator technological demo ("Reflections"), with which the manufacturer had introduced ray tracing for the first time – at that time still on four Tesla graphics cards with Volta. On the other hand, technical demonstrations based on Raytracing Justice and Atomic Heart games.
The demos were not available for the press under NDA. In the case of the embargo, the download should be possible for everyone.
Performance depends on the title
The running speed of Raytracing on Pascal GPUs and small Turing graphics cards depends, according to Nvidia, on the RT game or integration. Nvidia has supported this statement with the benchmarks of all graphics cards now supported, the driver itself, the manufacturer not having provided it in advance. All benchmarks were established at 2560 × 1440 (WQHD) and at the maximum ray tracing detail level possible.
According to the available test results, in the three new Techdemos as well as in Metro Exodus, but also in Full HD and with less details on ray tracing on all Pascal GPUs and the two TU116 graphics cards, no readable read frequency is not expected. The same statement provides the 3DMark. Even in the five applications, even the GeForce GTX 1080 Ti is far behind the smaller GeForce RTX graphics card, the GeForce RTX 2060, and the absolute SPFs are very low.

Two out of three games with GP102 possible
The situation is different in Battlefield V and Shadow of the Tomb Raider. In both titles, at least the fastest GeForce with Pascal, the GeForce GTX 1080 Ti, can almost reach the performance level of the GeForce RTX 2060. With 30 to about 33 FPS in Battlefield V and 34 to about 35 FPS in Shadow of the Tomb Raider, we can badume that games with a level of throwing of lower rays in Full HD are quite playable.
If only the games are taken into account, at least on the largest Pascal GPU, two games out of three previously available can be used in Full HD with ray tracing. For the GeForce GTX 1080, GeForce GTX 1070 and the two TU116 graphics cards, this should be rare. The first tests in Full HD can finally provide information here.
It is interesting to note that Turing without hearts RT disproportionately outperforms Pascal in all seven applications. The GeForce GTX 1660 Ti achieves a slightly higher SPF than the GeForce GTX 1080 and the GeForce GTX 1660 beats the GeForce GTX 1070. Without ray tracing, the GeForce GTX 1070 beats the GeForce GTX 1660 Ti barely. According to Nvidia, this is because Turing has also been optimized for ray tracing away from real-world RT cores and can therefore handle the corresponding calculations more efficiently.
ComputerBase has received information about this article from Nvidia's NDA. The only requirement was the date of publication.
