RetroArch Run Ahead

Has anyone tried this.. I've been putting it off but i did today. Wow. It's so lag free that i'm not sure i even like it. It feels weird. And i am afraid that if i use it too much then even an original console+CRT will feel laggy! lol

I use a Monitor instead of a TV and play with a DualShock 4 VIA Bluetooth (less lag than most wired controllers****). With RetroArch GPU Hard Sync set to ON i get no more lag than an original console would. Doing the whole Pause emulation, hold jump button, and advance frames until i see a response, i get the same lag that an original console would get (SMW for example has 2 frames built into the game. SM3 has 1). With Run Ahead on i get ZERO. Less than playing NES/SNES on a CRT.
