symmetry constraint results into massive screen lag

[cekuhnen]

deleting the symmetry constraints instantly speeds up the screen refresh rate when moving or zooming.

all settings are set to low - grid is off - profiles hidden.

this performance is very concerning with the new June update.

And this lag issue is only on Mac OS right?  And the constrained color indicator preview feature is turned off?

Yes sketch preview is turned off as well.

Something else is happening here on Mac Side.

The Win side inside the sketch engine is fine.

The UI redraw speed is so slow it is utterly hard to work fast and accurate with this current build

resulting in mis clicks left and right.

This is just for panning zooming and orbiting, correct? I

I'm doing a quick little test on may machines here.

Mac Mini (Late 2012)

8GB RAM

Intel HD Graphics 4000 (1 GB Dedicated VRAM)

Mac OS 10.10.2

vs. 

HP Z600 Workstation

24 GB RAM

NVIDIA Quadro 5000 (2.5 GB Dedicated VRAM)

Windows 7 64 bit

Even while editing the spline, I'm not really noting a huge difference between the two.

Would you mind recording a quick screencast showing what steps you're following? 

Thanks,

here is a screen cast with a simple sketch.

the issue affects everthing of the UI zoom in out drag draw etc.

the moment the symetry constraints are gone everything is fast again.
