High CPU usage

Wasn't sure in which sub-forum to ask, but well. Whenever I'm requesting a game report (any game), my CPU usage jumps to 80-90%. Tried different browsers, closed all tabs, etc. Won't help. Happens only when requesting a game report. Any solutions?

Well, it is doing a lot of calculations.  I expect CPU usage to jump. It only takes ten to twenty seconds to complete its calculations.

I have a ten year old PC, however, and Game Review has been using too much memory. The initial calculations will complete but any move recalculation puts it out of memory.

When a Game Review is loaded, the Analysis tab also loads, which loads a browser based engine. It used to be possible to turn disable that but now toggling off the settings doesn't seem to do it. Trying to find out if it's a bug or not
