Periodic FPS drops

[FlargleBargle]

I've been experiencing periodic frame drops while playing the mod but it doesn't appear to be a performance problem.

I've downgraded the graphical demand as low as possible but the drops are still apparent every second.

 

It may be because I'm using an M series graphics card, (for laptops) but the usual fixes for that issue haven't done anything.

Any suggestions are welcome.
