Lag when using Logitech G305 on macOS

[Customer Feedback]

One for you, Serif Support:

We also just posted a related issue in Publisher (but the issue is NOT the same):

 

We have experienced some very annoying lag on macOS M1 machines (Monterey 12.3.1, 16GB, 1TB) when dragging even basic shapes using this mouse, that is very popular:

Logitech G305

The problem is very bad in Designer with any combination of these settings (including turning some ie Metal on and off), so we have tried it all, and we don't believe we can resolve the issue using configuration - and we shouldn't have to:

The problem must be in Designer itself somewhere. It is very bad when display it set to 'Software' and improved gradually as we select OpenGL basic, OpenGL and Metal.

Here you see it:

If I then use a more humble mouse, the very popular (for travel) M187 Mini Mouse:

We believe it is the High DPI nature of this mouse that Designer struggles with - but we only see these lag issues in Serifs software (although Publisher struggles less)

Quote

"HERO sensor delivers exceptionally accurate and consistent performance with zero smoothing, filtering or acceleration from 200 to 12,000 DPI. G305 can save up to 5 profiles with up to 5 DPI levels each on the onboard memory."

We see the lag issue using any of the DPI modes the mouse has to offer in Affinity Designer on macOS. We tried on a Windows equipped computer as well using the same mouse with no issues.

The mouse is configured in macOS with Tracking speed set to FAST (max) - and Scrolling speed a step above default settings.

We never experienced this issue in any other design program or elsewhere - so please look into it, Serif. 

Regards,

Eddie

About a half year ago I faced the same problem and the solution I found was very simple — just decrease your mouse polling rate to 125-250 Hz. It will significantly improve your dragging/moving performance. DPI doesn't really matter here as much as polling rate does.

Initially I used 1000 Hz or 500 Hz on my Logitech G102 and performance was awful. Once I set it to 125-250 Hz all problems gone. Also recent performance fixes in 1.10.5 significantly improved canvas performance for me, especially working with large text layers and groups of objects.

That was a short answer. 

I thought so. After all, it means that other customers are experiencing the problem and need to find a solution.

Is the cause found and a fix on the way soon?

We find it very difficult to "sell" Affinity internally when it doesn't work with high DPI devices, and then our employees choose significantly more expensive software in our software catalogue, which is neither in our nor your interest.
