There is a lot of talk going on right now with the M1. Enterprise users are finding a lot of compatibility issues. Software simply not launching, but they are advised to report these conflicts so they can work on forward and backward compatibility.
There is a chance Terragen won't run on the M1 processor, but it may.
My main concern is performance. These ARM based processors are meant for low-power tasks and lean to the conservative side, and Apple is trying to flip that, while loading more onto the SOC and bloating it. A lot of the systems are only being configured 16/32gb RAM too, with no option to get more too.
This is all they crammed into the M1's in the image below. It says "High-Performance Cores" but how many out of the 8? Lol And how much is a high-performance core used for other performance based tasks like GPU/Image Processing, etc, that may happen with the OS during rendering?
