Poblem with multi-threading in 2026 release

[[An...]]

Hi, with the update 2026 i found out that when I polygonize a scan only 16 thread are being used instead of the 64 i have at my disposal.

My cpu is a AMD Threadripper 7970x (32C-64T) overclocked to 5GHz all core with 128GB 6000MT/s low latency DDR5.

In the 2025 release all the cpu is used withpout any problem and the polygonize function in very fast while only in 2026 i find this problem.

I already checked in option how many thread the software can use and is already set to 64.

Is there anything i can do? Is it a known problem or you need to look up into?

Thanks

I wonder if checkbox button is checked for use all resources. I would try also uncheck -> save -> check again -> save.

I don't see any option to use all resources, only selecting the total amount of logical core, I already tried to change the setting to a different value, saving it and reverting it to 64

Seems like 2025 had option which should behave same like this "Number of logical processors"

I am a little bit skeptical about using so much threads - it's a hell of programming to use such high number and keep it controlled.

Any news regarding this issue?

Hello Andrea Sacilotto,

we are aware that the behavior you mentioned is occurring in SW2026.
We are working on a solution that would be released with SW2026-SP1, which would enable you to again use all 64 logical processors of your machine.
