I've found that running "-malloc=system -maxMem=4094" through launch parameters stabilize the game's memory around 1.2gb, but then after 10 mins it goes into a non-stop stuttering and buildings disappears or go into lowres (or replicate on piece of texture all over it). Additionally my character goes into a low polygon affair. Game's memory usuage is down to 800mb at that point.
Couldn't verify this was constant, as I got kicked off the server, but non of the missing textures would load back as before.
Edit*Give it 10 min it will consistantly go low poly and not load textures while inducing massive stuttering and keep fps to a solid 5*
