Dear all,I know that it will be very simplified question and many other forums and topics, researches e.t.c are related to that in big detail.However, I need to start somewhere, maybe some experienced guys can help me.I have relatively good notebook - Acer Aspire 8940G (4CPU)4GB RAMNVIDIA GEFORECE GT240M 1024MSo technically I think quite good.Regarding frame rates no big problems, only on Heathrow2000 airport with many AI traffic in some views it is getting very low FRS 3-4 only, (whilst in the same airport and time if I make a view aside, it gets immediately back to cca 20 FRS)If I check performance monitor of computer, CPU usage is on level cca 20%, RAM usage on cca 50%. Disk after a while gets very low also.Even if I am not moving my plane, FRS stays constant on 3-4, max. FRS. What is the problem ? Where to start ?With CPU, RAM, graphic card ? Where to move further ? Is it somehow a limitation of FS2004 ?Any experience or recommendation would help !many thanks !JM

Hello,Acer Aspire 8940G Quad cores I read somewhere ... but I read also 1.6 GHz Regards.Gus.

If you're using add-ons like major airports, and possibly weather and AI, along with max sliders...on a laptop...your performance seems inline with the norm. Just to compare, at a major add-on airport, with PMDG, and partly cloudy weather...i probably get 20-25 fps...less if overcast, etc. And this is with a pretty decent fs9 rig thats overclocked.

OK, I see. but is there any obvious and way how to improve ?JM

Well, the two obvious things are to either lower sliders including AI %, to get a desktop computer. If you want to seriously get into flight sim you should def think about getting a desktop. If you intent on staying with fs9 for a while, as many of are, a fairly good desktop to run it won't cost you too much, esp if you put together the parts yourself.
