space as opposed to the Sid scrollers of yester year but at the end of the day we're gaming on flat two-dimensional monitors unless you happen to have one of those newfangled curved displays but you know what I mean showing a 3D image on a 2d display has long been an issue think for example about looking at a flat map of the world on Google Maps which uses a map projection that makes Land masses near the North and South Pole look way bigger than they actually are because translating a 3D sphere the Earth onto a 2d monitor or map is an imperfect process somewhat similarly your PC's graphics card has to project portions of 3D objects onto your screen a certain way so that they appear to have the correct perspective and depth just as real life objects do computers do quite a good job of this in most modern games if you're only only rocking a single monitor setup but if you're running three monitors where the two displays on the side are tilted toward you you may have notice that some of your games look distorted and skewed on the side monitors to understand the reason for this it can help to visualize your GPU as a projector behind a set of translucent screens if all three of them are lined up straight on one plane the image will look correct but setting up your monitors like this takes up a ton of space and limits your field of view so most people tilt their two side monitors inward but this would make a hypothetical projector display a stretched incorrect image on those same in displays enter simultaneous multi-projection or SM SMP a new GPU technology featured on NVIDIA's new GeForce 10 series that alleviates this problem by essentially showing a different camera angle on each screen going back to our projector analogy this is like having a separate projector

calling single pass stereo and lens matched shading that compensate for the fact that there are two lenses and the fact that the lenses are curved instead of planer and if you've noticed that I keep talking about NVIDIA that's because right now s SMP is only a thing on their new GTX 1080 and 1070 on supported games however as VR headsets and Surround gaming become more popular I wouldn't be
