Memory Leak/Preformance Issue

[zlotjko]

when it happens:
- hunting, lots of people on screen, long loading times (especially Mor Dhona), lots of teleports
before it freezes:
- minor artifacts on screen (pixels or group of pixels going in random colors) usually small size
- people disappearing, sometimes even A rank marks (and always S rank)
- game freezes for a second or 2, then continues, may happen 3-4 times before the "ultimate" freeze and unexpected error report (crash)
- i can be afk in the game for 3-4h, then start to hunt, after 10-15 mins a crash is imminent
how the freeze looks like:
- usually a drop of fps to 0-1-2 fps, game locks, but sometimes (not always) the chat window is still active.
- Does not effect other software, like TeamSpeak or Chrome
Tried:
- Changing the graphical settings does not seems to help with the issue
- Changing the number of displayed people and objects or displayable effects (skills) from other people does not help with the issue

What i think is the issue:
Memory leak. Since a large amount of people is going in an out, we could say that the mouse has become an elephant, and an error (tiny memory leak) that could be ignored, cannot be anymore. My guess is the gear / vanity gear "overwrite".
