NVIDIA’s Pascal architecture includes a wide range of technologies, with one of them being Simultaneous Multi-Projection or SMP for short. This technology allows increase in performance in VR titles and it’s all because of the dedicated engine in the Pascal core. VR titles are going to be coming in with full force in the future, and besides the Pascal architecture, future architectures will also come with this technology to provide the much needed performance boost for gamers.
In a benchmark run by Computerbase, NVIDIA SMP is able to offer up to 20 percent increase on the company’s GeForce GTX 1080 graphics card. The tests were carried out while running iRacing, which is an online car simulator that supports NVIDIA SMP. Though the title is not VR enabled at this current time, it does provide support for SMP in Multi-Monitor setups. Simultaneous Multi-Projection saves geometry processing time by having to process it across all monitors at once rather than individually. At the same time, it also saves GPU resources and increases performance.
Another GPU that was tested alongside GTX 1080 was the NVIDIA GTX 1060. While the GTX 1080 reported a 20 percent increase in performance with anti-aliasing disabled, the performance drop was minimal with anti-aliasing enabled, as the GPU was able to record a test result of 17 percent increase. Similar gains were reported while running the GTX 1060, and both GPUs were running at a resolution of 5760 x 1080, which easily kills the framerate of several GPUs out there.
iRacing uses a very early implementation of SMP, but it still shows the level of performance that NVIDIA and its latest technology has to offer. Naturally this technology will mature in the coming months, and it will immensely help Pascal cards to perform better in VR and multi-monitor titles.
