RetroArch fixes Input Lag

[fivefeet8]

I must say, I'm pretty impressed with the recent release of RetroArch 1.7.2 now up to 1.7.3. The newest feature is something called Run Ahead. From my limited understanding, it renders off-screen frames ahead and when you press an input, it renders the past frame with the input thereby making the input frame lag in less frames. It basically means what you're viewing on screen is a frame or two behind? It is a bit mind boggling to think about in the layman.

I've been playing around with it with various emulation Cores on my Shield TV. It's pretty damning how much I got use to the lag frames. I didn't notice it until I turned on the Run Ahead in a game with what I thought had low latency input only to realize how much more responsive it felt with the option on. It does make many games less authentic in some ways, but then emulation has sometimes been about improving the experience of these oldies..
