So. My video card and monitor are both capable of displaying 1400:900. This is what I have my Vista Desktop set to and it looks great.
What do I set the game resolution to? IS there optimum setting or should I just set it to 1400:900 like my system settings?
What is the best?
The higher the setting the better the look and the screenshot, but it also uses up resources.
Do what you feel is best for you.
if you set FSX to larger resolution than your screen resolution, you will only see a portion of the whole picture.
if you set FSX to smaller resolution than your screen resolution, you will see the whole picture in coarse grain. The picture does not look as nice, but your FPS goes up, and your game will appear smoother.
I went back and forth from 1400:900 to 1280:whatever, and did not see that much of a difference in appearance...
It looks good though.
1280 usually goes with 1024. i.e. a 4X3 aspect ratio
displaying it on your 1440x900, you will see a squshed image. The round gauges will appear oval.
you should also see a small increase in FPS using 1280x1024.
