Cura much slower on new, fast PC


Recommended Posts

Posted (edited) · Cura much slower on new, fast PC


I used to run Cura on a Thinkpad with 5th Generation i7, 2 cores, no GPU.

Now I upgraded to a Thinkpad with 11th Gen. i7, 4 cores and an RTX3050ti GPU. 

Both 16GB RAM.

Cura runs much slower in every aspect. The slicing itself is slightly slower, but the scrolling through layers (right slider in Preview tab) is so laggy, it's almost unusable.


Maybe two noteworthy differences:

- I'm now dealing with 4k, vs. FullHD display, but then again, this thing has a proper GPU to drive that.

- new notebook runs Windows 11, while old one runs 10.


One more thing: I had to re-install Curo once, because it froze always after a changing a few slicing settings.


Any clue what this could be and how to fix it?

    Sorry, please close, or delete this topic. It's much fast indeed (35 sec vs. 1:45min for the same job)

    No idea what was wrong. I re-installed Cura several times due to the freezing, and while it still freezes, the speed issues are gone now.
