I have been happily running Zwift on a 2014 Macbook with 4gb ram and an intel 5000 graphics card, but after having a few months off I tried it again today and when in the titans grove section it became very jittery (Newbury velo race). Oddly it was only really bad in this section. It was ok elsewhere, only jittery at times.
I tried turning the graphics down to low, but that didn’t help.
Has something changed with the requirements recently? I note the minimum now says 8gb ram.
Seems odd that it was only bad in the titans grove section though.
