ASE is a weather engine which just uses manipulates the textures better than the standard weather engine. REX has both but its weather engine isn't as good as ASE apparently.
do you have any screenshots in comparison?
seeing REX is quality images especially the cloud detail, i would like to get an idea of how ASE performs.
did try the config, seems to work pretty well. looking forward to downloading Rex 2.0 tomorrow. tried multiplayer seems ok, but i need to improve on my landing i seem to get the sinkrate alarm, or i miss the runway by a 100 yards.
this is what i normally do, drop to 3,000 feet at 240 knots with flaps at about 5 degrees, then decrease my speed to 180 at about 2,000 ft, then when the runway is about 1 - 1/2 away decend adjusting throttle to around 140 knots flaps on full and landing gear down, i do use the autodecend and autospeed. if you give out any pointers or any errors that would be great.
Not sure that you will want the first 2 really - I found them to be a terrible hit on perf although they did look good. Well UTX anyway.
They causes terrible microstutters for me and so much scenery popping. Maybe I just didnt have it configured correctly. I might give FS-GS a shout and see what he can do.
