These are not the same problems at all. Look at gaming monitors and Ping times to better understand the problem. (These aren't the same thing, but at least the underlying reasoning is closer). The VR problem is one of synchronicity. If your sitting looking at a screen of a movie or something, you don't need to change the image very often, and your brain will work it out. If there is something you are carefully paying attention too, like a ball in a sporting event. 30 FPS is not smooth enough (you will see gaps.), this also is worse with Tv's without phosphor display. And the ball will noticeably skip. So this trick gives you more frames with less time between them, so it won't skip. It's not perfect and some people get weirded out by the effect. BUT this has NOTHING to do with the VR problem. In this case it's synchronicity. Think about it, real life is relatively continues, there is no 30 fps per second, and there is reasonable belief that synchronicity has a much much faster ruler. You have a near perfect understanding between doing something and watching what happens when you do it. And if it seems real, but it's not. Turns out a large part of the population will get weirded out. And in the ol venn diagram way of thinking about it, that population and influential gamers is pretty damn high. So no it has to be fast ass cards. (there is a little bit of similarity, but one of the other problems has to do with speed of action. If your fast enough you solve by far the largest of synchronism issues. (remember when the rift first came out. Everyone was excited because they largely solved the synchronicity issue, but on low-res screens. The low res screen is problematic with moving input that is trying to reflect reality.If you move at the right speed you will get stuttering. While the timing will be right,but resolution stuttering will weird some people out. So it has to be fast enough to allow synchronicity enough, it has to be pixel dense enough that it doesn't skip unexpectedly differently from real life. None of this can be cheated, because we are not watching movies in real life. We don't ADAPT like when watching a movie.
