You can get bad performance if you install an RC and a beta. I noticed my installed game version (RC) was the same number as the beta, deleted the beta folder and it was ok after that. Had lag and jittery visuals turning etc, with them both together. I would just use the beta patch not the RC. I'm having to reinstall as I did not realise there was no rollback from the RC's.
Can you please clarify what's going on with the 1.62 beta.
I installed the latest beta's as they are made available on Six Launcher (to play DayZ).
Since 1.62 (95168+) I have not been able to play vanilla ARMA2 (1.60) as I just get a crash to desktop after loading a mission file. Several other people reported the exact same problem to me, on different servers, playing different missions.
The beta is NOT optional, to play DayZ.
Does this mean every DayZ player can no longer play vanilla ARMA2?
Freeborne 1.61+ needs a different battleye dll. BE 1.60 and 1.61/1.62 RC are NOT compatible
