Started testing the latest beta build from LM ... performance improvement so far appears to be about 15% across the board on my setup using this build.  Cloud shadows at sunset have much less impact.  Tested using 5 cloud layers at sunset which would normally bring my system to 10-11 fps (see settings in link below).  Also tested with high speed aircraft as they will stress out performance more than "normal" aircraft.

Used Captain Sim 777, Lockheeds F-22, and F-35.  Scenery is all Orbx with FTX Global, FTX Vector, PILOTs FTX Edition Mesh, and FTX OpenLC EU -- so I did try to load it up with add-ons.

Made a quick video here:

I'm finding I don't need to use SGSS AA now (this is good).  LM indicated they have done some additional work post this beta build that will improve water at Ultra performance -- so more improvements to come.  There were a few stutters, but they have been drastically reduced.  Sadly my video doesn't do my flight experience justice ... you may see stutters in my video that aren't a part of the my actual experience (yes I'm sure no one believes me, but you'll just have to take my word for it -- 2.3 beta 2 is MUCH improved).

Looks like I'll have a busy weekend testing.

Cheers, Rob.
