Weird FPS problem

Hello all.
I'm flying FS9 in the past few years but never encountered that strange FPS problem.
I've installed FS9 on my laptop due the fact i'm traveling a lot lately.
It's not that powerful, but it should run okay and indeed - I'm getting a steady 24-25 FPS (When limiting the FPS to 25)
BUT - Every time i change it to 2d cockpit view, the fps falls to 10-15. Strange ?
From years of experience with FS i got used to the fact that FPS usually falls in Virtual cockpit or spot plane view, and in 2d it should be fine and max. But thats the opposite !
Any idea why this happen ?
When i press Shift+1 in the 2D cockpit to remove the panel - everything is back to be ok, so i guess it's got something to do with the gauges.
It's happening on default planes and add-on planes.
I'm quite clueless and will be glad to get some help.
Thank you in advance !
