Could you give some infos about the display refresh rate? I am using a DPI display in my current build and while I am avle to reach playable refresh rates they are still far from the ones I reach with composite or HDMI. I always wondered how Kite made his display run so smooth
I think i read somewhere that it can do 125fps. If it's in dpi mode and you made it work it should just perform smoothly. Are you using a different lcd than mine?

@tinkerBOY I just noticed that DPI and SPI are two very different things and I am stuck with the worse option of them: http://www.watterott.com/en/RPi-Display-B-Plus

fbdelux, there's a trick called FBCP (FrameBuffer CoPy) that can alleviate some of the issues with SPI, but its not simple to implement. You might want to ping Will.I.Am on Discord, as I think he is working on it for another project.

Otherwise, adafruit has an article here about for her LCDs (which use SPI too): https://learn.adafruit.com/running-open ... itft-setup

I suggest you fdeluxe to open a thread here not on discord and ask about fbcp. People will be happy to help and the replies will be available to everyone :D
