I’ve been using kicad 6.0.0 for a while on my windows machine and everything has been working great, even for some large boards I designed with many components but recently it started being very slow to the point where it’s unusable in the PCB editor.
Just opening the preferences window or component properties window takes about 10 seconds. Dragging a pcb track is painfully slow, it basically gets stuck along the way while it tries to optimize the track. Interactive router similarly slow, getting stuck while figuring out the path.
My machine specs are: Windows 11 x64, Ryzen 7 2700, 32GB DDR4, Nvidia Geforce GTX1050 Ti, SSD storage. Graphics card driver is unchanged: Nvidia 126.96.36.19971 from 30-sep-2020. Task manager doesn’t show any significant load for CPU/RAM/GPU, all looks normal.
I haven’t noticed exactly when it started being so slow so I can’t really correlate with any other software installed on the machine or settings adjustment to Kicad itself.
I have noticed that for example when dragging a track within an open area, it’s very fluid but as soon as the track hits an obstacle, it starts responding very slow to the point where it hangs.
Things I have tried so far:
- Updated to 6.0.5 with no improvement.
- Switching from accelerated graphics render to fallback graphics with no improvements.
- Enabling or disabling antialiasing makes no difference.
- Testing with different projects smaller and bigger, no difference.
Any hints on what might be causing this?
