Extremely low FPS on more than average Rig
Soyeah, apparently, I can't run L4D2 at 1440x900.
"What do You mean with that ?", You might ask.
Well, the game barely reaches 40-60 FPS, always drops below 30 and lags 24/7.
It's the only game that does this.
"well download more ram lol" <- This.
Everything's maxed out, tried uninstalling every Mod and reinstalling the game, didn't work.
GPU's drivers are up to date.


CPU - Intel Core i5 3570K overclocked at 4.2GHz
RAM - 2x8GB Patriot Signature Memory (1333mhz) (Will replace them soon)
GPU - ZOTAC GTX 650 AMP EDITION (Will replace it soon)
Motherboard - ASUS P8Z77-V LX2
PSU: Cooler Master 750W Bronze

So yeah. What's wrong ?

How are other games running? With the same lag or just fine?

Tryed disabling the Multicore Rendering in the video options menu?

Did you formerly have better FPS? Rollback on gpu drivers may help. You should be able to get at least 80 fps on max settings. Vsync disabled? Tried different resolutions at different window modes?

To Razgriz: Other games run perfectly fine. Except bloody The Witcher 2 but that'a another story. I get about 200-300 FPS in TF2, about 90-100 in Dota 2, 200-300 in Half-Life 2 and 25-45 in Far Cry 3 (With MSAA Off)
To Gorman: Yep, didn't do anything.
To Sophia: I played L4D2 on my old Laptop and there's no difference at all. (Intel Core i3 @2.2 GHz, 4GB DDR2 RAM, Geforce GTX 520M)
I swear there's no difference at all.

Vsync enabled or disabled for l4d2?

I've tried enablign Vsyng + Trible/double buffering but it didn't do much.

Also, the game often crashes when the map finishes loading on a multiplayer game. Even after I reinstalled it.

Crash on map change... could be hdd.

1) Check the load on your videocard when running l4d2. MSI afterburner can help with that. Let l4d2 run for around 10min, then afterwards look at the logfile MSI afterburner has created

2) Make sure your CPU overclock is 100% stable. And I really mean 100%. Some games, are more sensitive to overclock than others. And a not stable overclock...well maybe l4d2 thinks its unstable, so it cripples your fps.
