Hi Callergo: I have that same problem... My rig isn't the highest end one, but it is quite, quite a good thing and it even freezes and FPS go to hell every time I fly over a city.
The greatest problem is trying to land in a city airport even an easy plane at 1 FPS...
The other day I made a last correction at 20 ft over the runway on my old A-1J "Spad" and next frame I was tumbled nose-down and I was written off. It is impossible to land this way!
If I ever find a solution I will post it!
In addition, realism is really amazing and makes a great difference when flying over the countryside but even so, there is still the other problem: the #/°°!! "fatal errors" that appear after any sudden maneouvre...
I use Windows 7 and I was aware that FSX and W. 7 isn't always a good friendly relationship, so I had downloaded a freeware solution to this problem: a little patch that had worked really fine. From 1 "fatal error has ocurred" each session I was experiencing pretty much as 1 "fatal error..." every 2 months or so.
Well, after installing FTX Vector I have had an increase in fatal errors frequency too.
If it isn't a fatal error, FSX freezes down for a long, long time; say 3 - 10 minutes or even longer.
Let's hope FTX find a real solution for this bug.
I'd like to know if higher-end rigs experience the same bug...
