PFE has a detailed modern user interface and rich regional voice set, which gives it an edge above many older dated FSX ATC. PFE Also has the BIG ADVANTAGE of taxi guidance +++++.
But sad to say from my experience so far coming fro RC4, PFE is running like on ice skates, always crashing.
Connect to FSX, "PFE Initialsing" then crash.
So i googled ["PFE Initialsing" crash], and you can see its quite common.
So a new thread on AVSIM that invites folks with PFE crashing issues to disscuss. At AVSIM there is wider odience.
The thread will get you new customers and you also on the record fix the crashing issues folks are having with PFE.
If PFE is stable, wow. currently for many its not the case
