MiSTer Vs RGB-Pi #2 - Input Lag?

Here I demonstrate how good is the lag in Raspberry Pi4 without any latency improvement, and also using Runahead. Also I show you how to accurately measure input lag using Retroarch, and how to fully eliminate the same, that's is, Zero input lag. Finally I show you a small comparison against MiSTer to show how well these Pi4 configurations work. #RGBPi
