this has probably been dealt already but I can't find any informations, except going through FS-GS...
The thing is I have a rather high end computer, not the latest but still very good I think, with lot's of RAM, 4gigs, and I still have the blurries. I tried some tweaks I found on the net to enhance FS9 graphics when using megascenery, which I don't use, but even if my computer seems faster the graphics are not really better.
for info, I run all sliders to the max, mip mapping 6, hardware rendered lights 7, bilinear flitering and AA on, global max texture size massive, target framerate 25.
my comp's spec are in my sig.
here are some example, it's a basic flight from seattle tacoma, with silverwing nice wheather theme, nothing more
here, the blurries start in front of the engines intakes

here, in the middle of the radar

the big black squares disapear usually after 1-2secs

as you can see the frame rate is very good but the quality is not the best...
any help welcome, thanks
