Hello, Aslain,
thank you for your interest.
As demanded here I provide you with the refering replay and archived logs with your archiver as attachement.
I hope you will find out, what the problem was/is. While the watersurface shivers also the displayed frames seems to decrease though statistics even of grafics-adapter don't change.
Thank you fAslains_WoWs_Logs.zipor your effort anyway.
