Finally an up-to-date EPKK scenery, that's what I needed.

If you want to fly in Poland, this addon is requierd

Very useful addon with nice clouds and other weather effects

Very good scenery, but performance could be little bit better.

This is tremendous for FS9 if you are (1)a KDCA fan and (2)flying around/near/to DC in any shape of form. Airport is great and frames are real ogod (at least on my machine). FPS is always my concern with add-on scenery and this doesn't disappoint. But what it adds in terms of DC scenery; the Mall, the White House and all the other famous sites, is worth the money alone. Well done Trop Sim!!!!!!!

When a real life Dash8-Q400 captain shared his techniques on how to properly hand fly this machine down to the numbers and it actually worked, that's when you know you have a solid simulation of the real life counterpart. System-wise it is on par. If there is anything I could complain about, it must be that it is very difficult to fly it SIC (but then again, its illegal to do so in the real world and that is for a good reason:-)

Very good frame rates on a mid system using windows 7, especially just above the airport and even over the city itself, which is quite detailed!

Its far more better then default, but I've been spoiled by Samscene where not only autogen is present but also a lot of custom buildings. This scenery has none of these, just custom autogen. I really would like to see some of Pragues unique buildings and castles.

Weather Engine needs updates (they come) but the rest is best there is out there for P3D. Adds so many cloud variations and features that ASCA does NOT have. So worth the money for me easy.

The summer texture are good, and blend well with orbx land class product. Where it falls down is the winter textures - pretty much non existent. Also, performance is horrible in P3Dv4. I hope they update it in the future and better optimise it for P3Dv4.
