Unreal Engine UI does not respect windows cursor speed

Hello,

this is my first time trying out Unreal Engine and I’ve already managed to discover a quite severe bug. When I opened a blueprint and tried to pan, the panning speed felt absolutely out of control. I am using quite high DPI mouse, so I am reducing mouse speed in windows mouse control panel. It seems that Unreal Engine absolutely ignores this setting, and uses hardware input of the mouse. While that is appropriate for in-game input, it is borderline unacceptable for user interface input.

Here’s a video showcasing the issue in detail:

Hello Rawalanche,

I was able to reproduce this on our end. I have written up a report and I have submitted it to the developers for further considerations. I have also provided a link to the public tracker. Please feel free to use the link provided for future updates. Thank you for you time and information.

Make it a great day

Any news on this bug btw?

The issue was marked as “by design” in the bug tracker, so it looks like developers see nothing wrong with the behavior. This shows very concerning apathy of developers towards the quality of their product. Very disappointing.

Is there a way to re-open the issue or open a new bug report for it? Pretty sure “by design” is a bug in this case.

i have this problem too as soon as i changed my mouse i realized that my normal mouse speed doesn’t match with the drag speed in the node editor, graph editor, content browser, etc
i also believe that its because ue4 doesn’t use raw input on the mouse
a simple solution would be them adding a ui.SensitivityMultiplier (x) in the ue4 console. how hard is that and im also positive that many people have this problem but they don’t write a report about it because not every one has a huge difference between the normal and pan sensitivity because we have different mouses

the only solution i can think of is that u could use a scripting program like AutoHotKey and use it to slow down the sensitivity when you hold down the right click (button you use to pan)

OR

you could set the windows sensitivity to the same sensitivity of the panning and use an external software to slow it down I think that might work im not sure but make sure that the external software doesn’t use the actual windows sensitivity multiplier value to change the sensitivity

“by design” is pretty much them saying “we are too lazy to fix it cuz ur the only one reporting it”

Can confirm this is still an issue in 4.26.

I think the development team should take note that there is an assumed paradigm of windowed applications generally respecting the combination of mouse DPI raw input AND windows pointer speed, and as a result, allowing a seemless transition between interacting with multiple different applications (such as sketchup, blender, illustrator, unreal). Unreal Editor seems to be one of, if not the only, application not respecting this established UI paradigm.

And we’re not talking about engine runtime, which understandably SHOULD just use the raw mouse input, like the runtime of any other game would, as well. We’re talking about windows control type interactions, window resizing, numerical scaling when you drag the mouse, panning your blueprint around in the editor window, etc, things you would expect to behave the same way they have for the last 20+ years of window based application usage.

It is quite common for users to want to use a higher DPI setting on their mouse, for the sake of finer granularity control in full screen applications like games, and then reduce windows pointer speed to offset that and still have reasonable speed at windowed application level. The way Unreal Editor is currently set up removes that possibility and forces the user to either use a much lower mouse DPI, or precariously navigate the various interactions in the editor at high speed.

This does not seem like an optimal situation.

With a new unreal engine major, I feel compelled to revive this.

Confirmed an issue in 5.1

I run a very high DPI mouse settings and then turn down general sensitivity in both Windows and games. This has a lot of benefits for both precision and accuracy, especially on very high resolution screens.

Editor screens like the Blueprints Editor having an accelerated mouse speed on drag is infuriating. Having an Editor mouse sensitivity would be an enormous benefit at the very least.

This is not optimal indeed.
