Chessbase and CPU Performance

Having noticed that Chessbase's Autoplay feature makes CPU usage shoot up to 22% where as when it's on pause it averages at 2% consistently.

I've made sure to turn off Heumas and Assisted Analysis, but the CPU performance stays the same.

I get the impression that some kind of engine is looking at the moves (despite me having turned off Heumas and AA) every time the Autoplay function executes a move.

What do you think?

P.S. I use Chessbase 14 - tell me what performance you get in other Chessbase versions.

I've e-mailed the Chessbase support team about this issue and I'm waiting for a replay.

I'll keep you posted.

My runs at more like 15 to 16%, but does this as well. Like you, I have assisted analysis and heumas turned off. This doesn't bother me, and it isn't a feature I use anyway, but it is curious.

I'm trying to improve my battery life since it's not as good as the other laptops I've owned.

It's curious as you state.  It's going to be interesting what they answer me.

Chessbase did respond and instructed me to lower the number of CPUs the engines use and also to create a UCI engine, which is more customizable.

I did let them know that, unfortunately, the Replay function does not, or at least is not supposed to, use the engines, especially with the Heumas and Assisted Analysis features disabled.

I did learn something from their answer, but, unfortunately, it does not offer a solution to the original problem.  I will have to do some experimenting, like taking off stuff in an effort to try and pinpoint exactly what is causing the surge in CPU usage when autoplay mode is active.

Note: I'm using the replay and autoplay terms interchangeably.
