[Chimera-users] Apple M1 chip

Silhouette edges in Chimera are quite slow using I think 5 extra rendering passes, so about 5 times slower than without silhouette edges. If we get an Apple M1 machine we will try it -- possibly its driver is doing that particular rendering operation in software making it even much slower. We won't be able to fix that.
You might want to give our new program ChimeraX a try. It's silhouettes add almost no extra rendering time. ChimeraX has most of Chimera's capabilities and will eventually replace Chimera. ChimeraX like Chimera does not have a native Apple Silicon build. We use 50 third party Python packages and all of those will have to have native Apple Silicon CPU distributions before we can provide that. But the Intel emulation on Apple Silicon is supposed to be very fast.

Of course, we understand it takes more time to learn the commands than to use a graphical interface! If you just want to make a simple spin movie (one rotation), however, ChimeraX has an icon to do that with a single click.

>>>> Chimera depends on 50 third party packages that would all need to be available for M1 to make a native Chimera version. We do not plan to attempt that. Our development work is all on our new program ChimeraX, only critical maintenance is done on Chimera. At some point in the future we will probably make a native M1 ChimeraX.
