ok graphics/fps: absolutely fine. scenery is an improvement, looks like fs9 with lots of enhancements and also much finer detail when closer up. i like. the fps issues can be sorted by whacking the basic graphic settings up to top; fs then decides what it can and can't do: eg. get rid of that water. i have had no issues with frame loss this way.
aircraft: i like the new beaver and crj cockpit. the detail and textures are very nice and like much payware availible now. the standard use of the vc is a massive improvement. gauges are sharp and move very smoothly. the incorperated view program providing unlimited movement and gforce effects are very welcome and a great addition to the sim. the ultralight is like any availible for fs9; good. the only issue is with the vc glass in the crj and beaver. also the baron is the same one as in fs9
atc: no idea, i haven;t had a problem. nothing new to report.
overall: i've liked the demo. there are a few issues, but i am happy to say it runs well on my system. for £40 it is cheaper than buying many additions for fs9. the default aircraft will certainly suffice for some time if all are of the crj/beaver quality.
