@Chuitox: probably this is a noob question but it bugs me all the time already:

is the framerate just something that affects how tibia is looking (like animation speed) or it affects also the gameplay (low framerate makes you lagg/bug things like depositer, npc trades, no fast healing)? Does tibia + xeno still calculate everything (e.g. healing) at the same speed?
Why does it bring so much performance improvement if you just change the refresh rate of displaying a new image? The background calculations of xeno for running/targeting/looting/healing are still at the same speed and i think thats the main workload for the cpu (isnt it?).
