After I have seen the impressive VC video of PMDG's 737, I'm thinking about exchanging my 22" Acer with a 30" TFT.Am I expecting a frame drop with the same antialiasing settings between the 1680x1050 resolution and 2560x1600 of the new one with my GTX480 in FSX?What do you think?

You would be pushing twice as many pixels, so yes, there is going to be an impact..Question is, where is the bottleneck.. is it just the video card or also CPU/bus/memory?

Presumably the purpose of a wider screen is to increase the visual perspective (width) as perceived by the pilot. If the larger screen is then moved farther away from the pilot's eyes (as I suspect often happens), then nothing is really gained apart from increasing the load on your computer as Bert has noted.The objective of course, is the same as with IMAX- to fill your eyes and brain with nothing but the sim cockpit and scenery.AR

Thank you very much for yours answers.I think, I will sleep a couple of nights before I will make a decision. It's too much money to loose if frames will drop and flying isn't smooth anymore.

Didn't see any difference in FPS going from 1600x1200 to 2560x1600 on a n HP ZR30w

And what AA settings do you use?

usually 8xSQ although with the increased resolution have been testing just 8xS with good results.

AR has hit the nail on the head. It's not about the size of the monitor but the distance that you view the monitor.
