Crysis Wars abusive memory usage

[Thundercast]

Hi ! I'm having some trouble with the crysis wars client. I can't play more than 5 min because of game crashes. I've been watching the *32.exe and *64.exe and both have the issue : the process' memory usage (and the game freezes btw) increase without any limit (often crashing around 3go of memory usage). As I was playing on very high, I tried to put everything in low, but nothing has changed : goes up to ~3go then crashes. Maybe it is a memory leak ? I'm already patched on 1.5.I could play it on that computer 2 or 3 months ago without any problem, I just don't know what it is and how to fix it. :-( Thanks for your help !

Infos :
•I tried to watch the memory usage just after booting the game : ~280mo, doesn't grow. It's when I'm connected that it grows.
•I tried to see what would happen on a server with a small map, nobody, and a high ping : it grows just as much as if I was with noobhunters' 40 player server.
•When I try disconnecting to see if memory usage with lower, it changes nothing, memory usage continue to grow. I once got kicked for inactivity, and the memory usage began to explode ( +40 mo of memory usage per second...).
•I have MWLL mod installed. Could it be that ? As said, I already played the game on this comp a few months ago without any problem. I installed mwll today and began playing in normal mod (I still haven't been playing the mwll mod). Maybe it could have corrupted some game files ?
•I tried reinstalling the game; I still have the issue.
•It doesn't happen with other games

This leak is also present in Crysis 1 solo and MP.

I do not have the problem with the " -dx9" app. It seems to be linked wih dx10.

(wtf "not allowed to edit this message")

Even if there are no answers I'm still hoping someone will find a solution.
When I run it in dx10 I get this (which I don't get in dx9) :
