FPZ Input lag
#1
Question 
Hi!

Now when my build is practically finished, I tried playing some games properly rather than just testing to see how/if they run, and felt like there was some input lag. It felt very noticeable in SMB, a game I've played to pieces over the years, so I decided to record it using the "slowmo" setting on my iPhone.

From my rough eyeballing it looks like 20-22 frames at 240fps of delay, meaning 5~ frames at 60fps.

Now, I know some input lag should be expected seeing as it's obviously not a CRT, it feels a bit unfair to bring this up even. I don't want to come off as if I'm bashing the FPZ, keep in mind I'm in general very impressed and happy with it. I'm just looking to see if there are any settings that are FPZ specific somehow that I could try out. I haven't tried the Retropie recommended things like changing the video frame delay, which I will ofcourse. The reason I'm asking is because it's a screen running through the GPIO pins, which I'm guessing has it's own implications and things to consider compared to HDMI. It's also what makes me think it might be possible to get better results than with HDMI? Maybe that's not how it works though, that the lag purely sits in the hardware of the screen itself, I really don't know.
