Problem Full Description:
Both (0.34.115106 Stable Branch) and (0.34.115106 Unstable Branch Experimental)
"Apparently" for no reason after 10-20 minutes of normal gameplay the game starts to enter into a state of decline in terms of performance, initially due to a drop of framerate per seconds (graphics performance). But in the meantime that performance declines with the passing of time you may notice that the frames value not always coincide with the observed ingame-lag. For example 60-70 fps and the game still presents clear visual interruptions.
This means that the performance issue isnt related with the player machine(pc) performance.
To confirm this i can say that it is impossible that a so extreme drop of FPS can affect players that before the patch had good graphics performances (like me).
In the end, the lag becomes so hard that the game crashes and you are forced to terminate it manually, sometimes it stops working itselfs.
When the player rejoin any server the whole process restart from the beginning of this description. {F30151} {F30152} {F30153} {F30154} {F30155}
