I tried the 1.1 beta and it seems to have the same problem as the latest AGS from git I tried - there is this unpleasant mouse stutter which makes it barely playable. So I tried the git AGS with Primordia and the same problem is there too. Btw, I use CentOS 7.
I'm running the 1.2 version in wine w/o problems, but not misbehaving native binary would be great. ;)
