Mac graphics jumpy

Anyone else noticing the video graphics on Macbook Pro are extremly jumpy? Setup for beta Mac was easy and like others I’d prefer to use over my POS Dell. I switched back to dell and graphics are much smoother. I have an older mac so wondering if that is the issue…thx

On my Macbook Air 13" 256SDD (early 2014) 64-bit fully updated. Some things are “itchy”, and bit to much heat coming between [ESC] key and screen.

Playing on a MacBook Pro Retina Display mi-2012 with Yosemite duplicated on a TV through AirPlay via an Apple TV, no issue whatsoever on either screen, very fluid.

Zwift will need very specific system information in order to be of any help at all.

Apple men -> About this mac

Provide OS version number, processor, memory and anything else that might be relevant eg: SSD drive or OEM.

On the same info screen press ‘More info’ and provide the graphic card info

Also your internet connection may be helpful eg: Time Warner Cable, 10m down/ 1m up.

I am having the same issue, both when mirroring displays and running native.
