Slow program

Hi,

When try  use mouse to zoom, Works  Very Very slow. I'd like my Librecad more fast,. Is it possible?
I use windows 10
64 bits

Thanks

I think that depends on your mouse and wheel settings. Is it only LibreCAD, where the wheel lags?

On large and complex drawings LibreCAD indeed is very slow. It wasn't designed for that.
It may help a bit to switch to View - Draft.  Line weight, hatches and images are not shown then. In version 2.2.0 rc text is rendered as boxes only when very small, helps speed up too.

The future V3 series aims to improve on this issue, but not to be expected in the next time.
