Put in a gts250 1gb card which has improved graphics considerably. Been playing around with various settings, sliders are currently 43433 with ground object density high, shadows off and all recomended offs in the config file. Frame rate restricted to 30 and am getting pretty well near to that nearly all the time so quite happy. Haven't embarked on a campaign yet will probably wait till I get my free track made and running. I find the hat switch clumsy to use and spend a lot of flight time wondering where the intended victim is, don't use the targeting aids.
This is the best flight sim I have ever had, does anyone else remember the sims with the flat triangular wafer thin clouds, perhaps I am thinking of flying corp, not sure as I haven't been able to run that for a long time under xp.
