Polling Rate

[dahkneth]

The polling rate of the Magic Trackpad 2 has been 95 Hz for sometime. With MacOS 16+ polling rate has increased for the Magic Trackpad. I've seen reports of polling rates up to 144 Hz and have tested myself with rates up to 125 Hz (my monitor can't go higher). While if I use it on Windows with this driver or the driver this is based on I can only reach 95 Hz polling rate.

95 Hz is a bit low and will feel sluggish on a modern monitor so have anyone investigated in how MacOS have unlocked/changed the polling rate when the device is connected to a Mac with MacOS 16+ and how that could be implemented in this driver?

hi,

I need to take a deeper look at the imbushuo driver code to see where it is specified and if it can be modified. I hope I can do that soon.

The same question was asked here (without an answer): imbushuo/mac-precision-touchpad#515

I can confirm that MacOS Sequoia (15.4 in my case) does indeed support higher polling rates; potentially up to 250hz from online reports I've found, but limited by the monitor's refresh for some reason. Due to this, as I, too, only hve a 120hz display, I'm unable to confirm anything higher than that.

This seems to mostly (entirely?) be a software-related improvement rather than a firmware one as my trackpad was smoother on Sequoia as soon as it boot up. I let it update the firmware anyway, from 1.9.2 to 3.1.1 but, as far as I can tell, that's unrelated to polling rates.

It's also important to note that the trackpad post firmware update is definitely choppier on my old Ventura install, suggesting again it's got to do with MacOS rather than the device itself.

Might do some more in-depth investigation, will post if something of note comes up.

Just in case this can help anyone, my device is a black Magic Trackpad 2 lightning, which might potentially be different than the original white one.
