I’m noticing input delays with any kind of input (eg: rotation, brushes, etc.) when using a bluetooth mouse and it gets even worse when using an external monitor. Input timing is seemless when using the trackpad without any external device.
What seems to be happening is that there seems to be a “firing” delay when clicking, The input doesn’t seem to register at first. When it does register, it seems to “catch up” and so the input seems to jump straight to the result rather than showing a smooth input from start to finish.
Input timing is fine in other programs such as Blender, so I can isolate this issue to Nomad and bluetooth and/or external displays.
The first video here illustrates the timing on my Mac M1 without any external display and just the trackpad: Nomad - 30 September 2026 | Loom - you can see how responsive it is.
This second video illustrates the delay on a bluetooth mouse and an external monitor: Nomad - 30 September 2026 | Loom - this is very noticable in that last brush stroke in the video.
It’s slight, but enough to be extremely frustrating to use.
Having the same issue on 2.9.32. I have an second monitor, and haven’t tried disconnecting it yet, but yes…SUPER annoying. Not a deal-breaker, but not nearly as responsive as on the iPad.
I did…still has about a half-second delay. I’m using a tablet monitor (XP-Pen) and have tried plugging in my BT mouse to no avail. Again, it’s not as if it makes it unusable. Trust me - I’ve been having my fun. I have some other things I can try/other switches to flip/dials to turn. I’ll keep you updated if I find a culprit on my end.
I was getting pretty bad lag (much worse than the OP’s videos, maybe because I’m on an older system) when using Bluetooth and my XP-Pen Deco Pro Gen 2. Plugged in was fine, but when using Bluetooth I would get both pen and mouse lag. I haven’t had any lag for weeks now after changing these two things.
Disabling VSync in Nomad
Enabling High Performance modes for both CPU and GPU
Give those a try if you haven’t. I didn’t have to disable “extra input samples” as stephmoi suggested above, that was the next thing I was going to try, but my problem was solved by then.
Yup, tried both. VSync off causes (expected) tearing, and the lag problem persists. What is SUPER weird is that when I slide the Nomad app TO my secondary monitor (the non-XP Pen one), I have no issue whatsoever. It has to be a pen monitor thing. Now I have to see if my Wacom causes any delays. Getting closer! Thanks for all your help so far!
