FPS slowly degrades over time, persists after game restart

<div class="IPBDescription">title</div>As the title says, as I play Natural Selection 2, my system slowly runs the game slower and slower, and it's isolated to this game. It takes generally two mid-length games for my frames to really start dipping, but it sucks that I'm in the mood to play for prolonged periods, and then this issue persists and I have to take a break for a couple of hours.

I've tried restarting the game after the dips happen, but I get into a session, and the frames just stay horrible. I generally run at 65 avg frames in game and 50-ish in HEAVY fights, but when this issue persists, I go nearly to slideshow speeds, with an average of 35 frames and a minimum of 15-20. At first I suspected it to be a memory leak issue, and I did notice that NS2 takes up a lot of resources, but I don't think that's the case since it persists after restarting the client.

I'm crossfiring two ATi Radeon 5750s.

My rig right now is :

I really enjoy this game, but it gets unplayable, and I'd really like some help.

    I have had the same thing happen to me. Game performance degrading after a period of time. I believe it might possibly be a memory leak.

    Might be. Dunno, is anyone else experiencing this issue as well?

    Also, Strider, are you running a crossfire set up, just in case?

    Try updating your drivers, or reverting back if you're already updated. This sometimes helps. You should also monitor your temperature and etc. for your system to try and isolate the problem. You should also try restarting steam, just to further isolate the problem.

    I've done this with slightly outdated drivers, and I'm doing it right now with the 12.11 Beta drivers. When I made the transition, my maximum frames skyrocketed, but the slowly degrading framerate issue still persisted. I monitor my temperature at all times, that's not an issue. Actually, this game doesn't make my rig get as hot as some other games. I've restarted my PC after playing and it made the game 'fresh' so to speak, and I could play without the framerate issue until about 1 hour+ of gameplay. The next time my frames start to dip, I'll restart Steam and the game client and report back with my findings.

    I'm not on crossfire. I'm on a single XFX HD5770 12.11 beta drivers

    Then this may be an issue with the HD 5000 series cards if it's not a memory leak. I can't be sure. If I recall correctly this issue was still a problem when I use only one of my two cards, so I'm pretty sure it has nothing to do with crossfire.

    Bump. This is a serious hindrance to me playing. I actually decided against playing for the past two days because of it.

    I have the exact same problem. When I start the game I get a solid 40-45 fps then after 5-10mins it drops to 20-30 and 10 when in combat.

    Game performance will always degrade as the game progresses due to both sides expanding and building more structures. Aliens, in particular their infestation, is the primary culprit of reduced performance.
