I thought I'd post my findings on the 14072 beta patch so far in comparison to the 13954 patch.
On the ground with the 13954 patch; fps:32 avg:33 max:46 min:14
On the ground with the 14072 beta patch (with only SSAO turned off); fps:33 avg:45 max:46 min:33
In the air at 10,000ft with the 13954 patch; fps:20 avg:33 max:98 min:0
In the air at 10,000ft with the 14072 beta patch (with only SSAO turned off); fps:58 avg:45 max:115 min:0
There were far fewer stutters so the game felt a lot smoother to me, on the downside I still have building\town shimmering but it could be caused by my settings.
I'm going to continue with my small test and tweak the graphical settings some more.
Here's my system specs and settings:
Intel i7 920
Gigabyte EX58-UD3R
Corsair 6 GHz DDR3
Nvidia GTX 275 896 MB
Windows 7 Ultimate 64 bit
