Can someone help me please.

Thanks guy's, but although I'm running a laptop I can say that it's always ran fsx and addons with very suprisingly good performance for which I was very happy with and don't recall this slide show stutter every 30sec's for 5sec's at a time and silky smooth and sharp in between and then something twigged that I upgraded nvidia driver to version 335.23 which seemed about the time this all started so I uninsalled it and reverted back to what I remember being amazing graphic's and silky smooth, the 320.49 driver, and presto the periodic slide show has disapearred, I;m obviously no computer wizz but it;s definately worked, maybe something to do with the refresh rate, vsync, I dont know. Ric, completely agree with you on the soup bussiness and for a long time now have really only taken tweaking advise from the post's by Paul J, time for some simming and not tweaking.

Cheers Rod..
