Well - got the pack, installed and activated with no problems, and while I had FSX running very well before, the FPS were down and THE STUTTERS WERE BACK - bigtime! Desperately turning on the DX10 Demo mode only made matters worse, with the nice blue sky color transitions, from light horizon to dark overhead, showing as solid horizontal bars.
I have been working hard to go through all my settings with little progress. Additionally, I find the new planes pretty on the outside, but with unsatisfactory panels - especially because of no 2-D.
I have never been whining here before during 10-12 years of flightsimming, but this time I am hugely disappointed. Remember the promises of DX 10 relieving the CPU, which was always the bottleneck, causing me to buy a whole new computer with Vista and a ridiculously expensive graphics card, and for what? Now we can only look forward to FS11, which will probably be designed for DX xyz, which will require a new, ridiculously priced graphics card to be fully utilized.
I will continue to try to find settings, that would show SOME improvement, but if unsuccessful SP2 will be uninstalled.
