TBH, it was only $5, 4 Euros, at the time, no reason to not to have picked it up if only to let it sit til they fixed these alleged issues.  Although, I haven't run into any issues, aside from FSUIPC, and performance is much improved over FSX prime.

I do hear that repeated more often and its certainly a positive that it runs better. However, I haven't seen anything concrete with regards to the Steam version having better performance. Hell, I can max out default FSX and easily exceed a 100 frames, so I'm not entirely certain what increased performance is being seen.

The Steam FSX Support forums also have topics cropping up relating to the good 'ol UIAutomationCore.dll issue.
