Help: Unsure if CPU is identified correctly

Like i said, im unsure if my CPU gets identefied correctly. Reason is, that in lutris own system information, it tells me that only 2 cores would be there

But in system monitoring it says 4 cores.

What does Zorin now use?

Try either one of these in the terminal:

Should tell you the correct number, they do for me.
As does Zorin menu -> Settings -> Details -> About.

It tells me that there are 4 cores, but nowhere is said if it has 8 threads or just 4 …

Use lscpu

Lutris shows 2 physical cores and 4 virtual cores.
Monitoring is showing all 4 virtual cores.

See here for information on cores and hyper-threading.
