I have version 14.3 on Windows 11 (24h2) with an i5 1235u and I noticed what seems like simple analog circuit is simulating quite slow like counting up in .001ms increments as if they were seconds so after 10 seconds it has only made to .010ms, it's not very useable. I have simulate as fast as possible selected and have changed the timestep and other suggestions I have found but no real change. I checked the task manager and see its only using an 8th or so of available processing power, is this normal, how do i get it to utilize more of the cpu? Thanks

ooops that image didn't load correct

oops that last image didn't load either, one more try

Maybe it is only using a single CPU core out of eight? Some calculations cannot be parallelized. Change the performance graph in the task manager to show logical processors instead.
did you know that you can embed pictures into posts directly?

Thank you for letting me know about the embed images. It appears to be using a few cores judging from the difference between the two snapshots, but why wouldn't such an expensive and mature professional product not use what's available from the system? Multithreaded spice solvers have been around for a while, even free video software like VLC can use all core while rendering a video and it's FREE. Not even going to mention spice solvers that run on GPU's now. Another thing is multisim doesn't even tax the cpu enough to get it up 4.5ghz, but VLC does? I would just go use one of the other products but I been using multisim for quite sometime and know it well and like it, i would just really like to see it run faster.
This is multisim running
This is no Multisim

Unlike e.g. video rendering, some computational algorithms cannot be parallelized, for example if each new computation must wait for results of the current computation.
