Poor Graphical Performance on M4 Mac

sagewlivingstone — Mon, 08 Dec 2025 01:43:57 GMT

Hi, I'm trialing Fusion 360 now and I've been seeing rather poor performance right off the bat on a brand new MacBook Pro M4 Pro machine.

The canvas rending is considerably low refresh rate- it's quite easy to see with just panning/orbiting. I don't have a frame rate monitor software set up on this machine yet but this is clearly quite bad, compared to my mouse cursor or other videos of the software online. The model in this example is very simple, and I've seen worse performance on even slightly more complex models. I can't imagine how this would perform on full assemblies. Surprising for quite a high end machine.

Interestingly turning off high-resolution canvas graphics doesn't seem to help the issue. This will likely be a show-stopper going forward unless I can find a fix.

@sagewlivingstone are you using the trackpad or the mouse to navigate?

Trackpad input on macOS actually uses a different event loop compared to the normal mouse, and regrettably it is limited to a lower polling rate than mice which results in choppy navigation.

One way to overcome this might be for us to add some event/frame interpolation or momentum/inertia to smooth things out, but what you are seeing is actually the raw event output from the trackpad by the OS, and the low frame rate is actually the gaps between those events.

@sagewlivingstone,

Please also try with Performance preset as what @jacob.weinstock has suggested in another thread to see if the frame rate will be different.

And if you still feel there's slowness in your side, please help submit a report using the "Report Performance Issue" option located under Help → Support and Diagnostics.

Thanks,

Lisa

Yeah nice assertion, you're totally right. Using a mouse the issue is completely gone.

While it's not my main setup, I'd love to be able to use Fusion on the go on occasion with just the trackpad. A bit of input interpolation would go a long way here.

Thanks 🙂

Hi, checking if there's been any progress on this issue? Is there an issue tracker I can follow?
