During the gameplay I noticed the game has lag spikes at irregular intervals with the main cause in the 'flip' parameter which I observed sometimes add an extra 1 second to frame draw time! I have tried turning V-sync on/off with no effect.

No mods installed. I have attached screenshot before the lag as well as it shows the dip in UPS.

Any ideas what might be causing it?

It looks like as it would look like when you tell the game to run at lower speeds with commands, at least the UPS part "before lag" is. It isn't busy rendering either, it just waits, for no obvious reason.
Cannot check the save right now though.
