Laggy interface on macOS

Post by BobRockefeller » Wed Feb 19, 2020 7:48 pm

I'm running macOS 10.15.3 and QCAD-Pro 3.24.2 on a iMac Pro (3.2 GHz 8-Core Xeon W, 32 GB RAM 2666 MHz DDR4 RAM, Radeon Pro Vega 56 8 GB video card).

Many QCAD operations are laggy. Selecting an element, for example, highlights the element in gray, pauses, unhighlights the element, pauses, highlights the element with its 'handles' and updates the Properties dialog. Clicking where no elements exist deselects all after a similar flash and pause of highlighting.

Drawing a two-point line is slow, too. The second point lags far behind the mouse as it moves. After clicking the second point in place, there is another pause before the tool continues for extending that line with another.

Do I have a setting out of place somewhere? Is they a way to get QCAD speedy?

Qcad might get slower with huge and complex drawings.
But then we talk of really big files with lots and lots of blocks, splines or complex hatches in it.

Other examples can be 3th party dxf files.
Or faulty dxf/dwg files.

For that we need the examine the file itself.

If you have the explained behaviour in a new drawing then there is something not right.

It's not a complex file and it is a new drawing. Where should I be looking for a poor preference choice or some other configuration problem?

With a new drawing I meant one started in Qcad from zero.
You quoted back the '3th party' too.
Do you mean it is a new dxf/dwg from a 3th party?

The most recents post about lag are about:
Correct installation.
Blocks, Blocks in Blocks.
Splines or very short beziers-strings.
Many or very complex hatches.

Start by the first.
Do a clean and correct install.
This did solved it for so many.

Are there any notes or suggestions for ensuring a "clean install?"

I have a file that started and a DXF export from another app and then was greatly redrawn in QCAD. But a freshly created new QCAD file shows the same lag.

I have no blocks, splines, bezier-strings, nor hatches. It's a very simple line and arc drawing.

Hi, I recomment to follow the installation tutorial by the letter and it should work like a charm.

One side note - never mix different QCAD versione in the same subdirectory. :wink:
Work smart, not hard: QCad Pro

If a thread is considered as "solved" please change the title of the first post to "[solved] Title...". Thanks!

I followed the instructions. Fortunately they were very simple! And I only have the one QCAD version.
  • Deleted the app.
  • Opened the DMG for my macOS.
  • Dragged the icon to the Applications Folder
The interface is still laggy. I've attached the file I'm working on in case there is something in it that can pinpoint the problem.

No lag what whatsoever with the file.

No. Where is the ini file (macOS).

That fixed it.

And after some experimentation, it seems as if the "problem" is switching on "Use full resolution for Retina display."

With that switched on, the lag returned. Bug? Or inherent limitation?

Using the full retina resolution will be slower by nature than using the normal resolution (QCAD has to compute / render four times as many pixels).

I understand that. But I have other vector-based applications that do not slow down, or if they do, not to the point of noticeable interface lag.

I thought the days of lines at an angle rendering with jagged steps were over for modern, powerful computers such as the iMac Pro.

Are there plans to upgrade the underlying rendering engine to solve this? More and more computers, and almost all Macs, have high-resolution displays and those computers are especially prevalent in CADD.

Unfortunately, we have to rely on underlying toolkits for the rendering. If you're not happy with the performance or rendering quality of QCAD, I'm happy to offer you a full refund.
