first impressions: very positive
as always i'm among the most blessed when it comes to side effects etc, nothing weird to report besides the grass on the hangers; no trees massed pop ups, no roads between channel, no FPS drop with clouds, nothing weird in the landscape thus far; i did see grass flashing on the screen once, when about to land
- clouds seem to pop on/off less
- the bullets ricochet really nice and render further, both mine and the AC nearby, overall a big thumbs up for tracers.
as for FM,
- the radiator now seems to affect speed
- i see it's noticeably harder to overheat the Spit IIa
- seems to be harder to enter a spin in the Spit
- enjoying improved speeds, like 290mph sea level; seems easier to catch those buzzard 109s, i'm certain they were having quite a harder time, they've been enjoying far to much advantage lately
- throttle back to good behavior
- blessings be heard, it's finally possible to climb up to 20000ft and maintain speed
(didn't try any further yet; before beta 2 the engine died on me above 14500ft)
negative
- stutters slightly up, but not troublesome
- FPS drop remains when more than 2 nearby human AC
- sometimes the enemy human AC display a jumpy behavior, but that could've been lag
last comments:
- to all affected by glitches, test disable or reduce the graphics card OC if you have it; i have none, perhaps CLoD it's too sensitive about that?
- i had the new nvidia beta drivers before this patch (had previous beta) and can confirm it did very well for the stutters, had them reduced almost to none (especially noticeable on take offs)
- remember (once again) to delete the conf.ini on "C:\Users\
USER NAME\Documents\1C SoftClub\il-2 sturmovik cliffs of dover" and empty the cache folder on the same path
- tested online on 4 flights in ATAG
edit:
negative:
- spoke too soon about the trees, now i get the massed pop up on a narrow square around the plane
positive:
- the stukas now have dive siren, heard them when pursuing a wing diving over hawkinge; how cool is that? 
- better MG sounds with the browning
