Some answers above associate the problem with secondary monitors. I know because when my cursor starts stuttering, if I'm watching a show (say on the TV App), the video stutters in the exact same manner. To be clear, this is more than just a mouse/trackpad input problem. So this is not an answer exactly more of a workaround that I've found. Either way you approach this, good luck - the interaction between apps can get hard to track even with half a dozen apps and utilities added to one build. This last step is hard and can take a long time, so unless you have a hunch which app or change is causing the performance issue, it is sometimes easier to focus on a clean slate to confirm it’s not a bug. Once you’ve ruled out hardware and tested a clean OS, restore your data and then analyze if some app or setting or change has had an impact on the performance. More likely is you’ve changed the system and will need to backup all your data and apps and settings and perhaps try a clean install and make sure the OS and hardware alone can keep up with your pointer. Lots of background processes or a stuck process can aggravate this situation and disrupt the pipeline of inputs.Īlso, if there is a faulty device in your USB or thunderbolt buses they could be flooding the input without you realizing it and removing that extra input might fix the issue immediately. Depending on how fast your display syncs, you might have a small issue where one program is causing the system to triple buffer or worse or you might have a more complex situation where several programs are overloading some portion of the system.įirst steps are use Activity Monitor to check for things like GPU or CPU overloads or just high usage. This talk is focused on iOS which is far more simple than macOS since less program variability and less modifications are possible on iOS compared to macOS. So maybe just might give this small program i try.Īpple has some good content to explain the general concept of a hitch, which is when the system isn’t responding fast enough to react to user input and make a change on screen. I didn't know what was going on, but the stutter issue just gone. Magically after using this software, all the stutter using Bluetooth Mouse is gone. 7 days trial, so might try if this is works or not. And install this software called Smooze ( ). Then stumbled in just one discussion forum. This happens for sometimes, change to Wired mouse the problem was gone.īut I am still trying to make my Logitech Bluetooth works as I like the mouse a lot.ĭid many things in many forum discussing this problem. I tried the mouse using Bluetooth and also the Dongle come with the Logitech mouse. Using USB-C to DisplayPort Connector for External Monitor.And using my Macbook Pro 16 in Clamshell mode. Really annoying, especially when working on photoshop. This seems to get me responses a lot closer to what I was used to back in the day using linux' low-level DGA mouse input which just mapped any pixel the mouse moved to a pixel on screen for perfect 1:1 control.I have this problem for sometimes. (Using any of my mice I seriously need to loooower the sens in-game since they both top 5600 dpi). What I did is use USB Overdrive and disabled its acceleration option, but set the speed of the mouse cursor in the standard osx prefpane to minimum and the usb overdrive speed to max. (disable it and then reboot I think).įurthermore you can set the disableosx mouse accel cvar in ioUrban terror (I looked it up in the source code and it's legit). There is also a prefpane app called secrets in which you can disable this 'annoying feature' called Beam Sync. This means you get 1000/60 which is about 17ms of delay just when clicking. Well, this mouse lag is partly because mac os x seems to sync a lot of stuff to the update of its display which is most likely 60 Hz.
