I have downloaded and installed the C130X to my computer and the FPS were terrable, with minimum scenery settings and using the standard Grey USAF C130E I was getting 1.75fps at an airport.
I fitted a new 7500NVIDIA Graphics card and it did seem a little better.
I assumed that installing service Pack 1 would do the trick but it didnt.
Installing Service Pack 2 did and now with medium scenery settings I get good frame rates and the C130 is a pleasure to fly.
Cant wait for Captain Sim release all thos addons.

Chazzer :D :D ;)
