Just got fs9 today and installed it, reset etc but the textures are very blurry almost like i am running the wrong resolution or something. I can barely recognise the name of the airline on the aircraft even with the sliders set to minimal. I have 256mb of ram avaliable.
Any suggestions?

You set the settings to minimal and you get bad textures, set the settings up, and the clearer it gets. ( slower!)

Rightclick on your desktop, go to properties/settings/advanced, find your video card tab at the top, and set the quality settings  up higher, (all the way up, you can back them off as you need too...)

Those are your Video card driver settings, the other quality settings are within Flight Sim itself. Crank it all up and then start backing off to achieve an acceptable frame rate.
