I picked it up and gave it a good try. I run an overclocked i7 950@4.2GHz with a GTX470 and 6Gb RAM with FSX on an SSD. I find the smoothness of the PMDG JS41 to surpass Flight1's T182T here. Testing in FTX territories with my standard settings for the regions, I noticed some definite stuttering of gameplay, something not experienced in any other addon I have. I got better performance in Aerosoft European locations like EDDH with UTX Europe active. But still not that smooth experience I was hoping for. It is a great simulation of the G1000 and so on, but I felt compelled to take advantage of the 30 day money back guarantee. The fps hit was a noticeable 5-10, which may not be an issue per se for some. But the loss of smoothness was my showstopper, particularly as my predominant use for it as GA would be vfr looking at the world passing by out of the windows. The refunded cash will be going towards perhaps the ngx or some scenery. Andrew
