Bug report - Rendering on CPUs with P-Cores and E-Cores

Hello,

Yesterday I switches to a i5-13400F with 6 P-Cores and 4-E-cores.

 

While rendering only the (much slower!) 4 E-Cores are involved, not any P-core. 

I tried to set the number of processors to manuell in the preferences -> no effect.

 

I'm on Windows 10 pro 22H2 (all updates) and Fusion 360 2.0.15995 x86_64

 

All power settings are set to "high performance"

 

So this CPU is a real "downgrade" in Fusion 360 😕

All other applications are running fine (i.e. benchmarks, all cores are used)

 

In the german support forum there are also people suffering from CPUs with e- and p-cores.

 

Regards Matthias

The only workaround I have found is to disable E cores in the bios if you want to do a render. There are several tutorials online on how to do this, just search "How to disable E cores".

Can't find what you're looking for? Ask the community or share your knowledge.
