Hey guys, just bought the pro version.. I had been on the road and just with my lower end macbook pro and pleasantly happy with QCAD. It was pretty snappy. Doing really really simple overhead drawings/plots. Like extremely simple shapes, nothing complicated.
I got back to home office and installed and fired up qcad on my MUCH more powerful pc workstation and am quite disappointed with the performance of the GUI overall. on the less powerful laptop, zooms and pans and scrolling is snappy and responsive. On the PC with exactly same drawing (or even a fresh blank drawing) the same operations are sluggish and lag behind. It's almost like the gui/drawing refresh rate is cranked down to a really low FPS or something, on the windows version.
Is this a known issue?
I dug through QCAD's settings trying a couple things (threads, etc), and the forms here and am not really finding anything. QCAD is using practically no system resources on either machine which is about what I'd expect. Nothing is overloaded in other words.
suggestions?

Hi westonw - welcome to the QCAD forum.
I never experienced a performance issue with a drawing described like this:
No. Not when QCAD was proper installed ...

Please attache to this topic the drawing (dxf or dwg) which caused the QCAD performance issue on your PC or if confidential an example drawing which shows the same issue. I look forward to test it with a standard Win10/64 PC on my side. Thank you.

I'd start by resetting your configuration:
https://qcad.org/en/tutorial-resetting- ... figuration
Please report back if the default settings also show that problem.
Preferences that can have a performance impact are mainly under:
Edit > Application Preferences > Graphics View > Appearance > Display and Performance
Try to lower the number of threads, disable full resolution for high resolution displays, disable anti-aliasing. Also: how large is your screen and do you run QCAD in full screen mode? If so, try to run QCAD as a smaller windows to check if that has an impact.
