Good you are pushing it out, but some points:
+ FPS seems to be more stable, it usually stays around 62 which is the MaxSmoothedFrameRate, with occasional drops into the 50s.
+ Less audio stutter, but still there, especially the recon plane and still the STGs.
- Getting ~1 second lags that do not seem network-related and were not there before in the non-beta.
- Got a serious bug today but it might already be in the non-beta: I was playing Russian Commander for 1 round, then after it ended I was in observe mode - but had apparently actually still spawned. I changed team, died of course since I was spawned, then changed back. I was unable to give artillery orders and for some reason it seemed I was ordering the Germans (bots) where to move ... it was a strange one, so I bet it would be hard to reproduce
