Modern Warfare 3 Lag and slow FPS... Please help me troubleshoot!

post #1 of 6
Thread Starter 
Hello guys,

I just downloaded MW3 on Steam and noticed right away it wasn't running right on my laptop. In single player and online, the game just lags and fps drops when a move my mouse, even on the lowest settings. My laptop should be running this game fine! I have not updated my GPU driver, actually I'm unsure if I even can because it as a switchable ATi/Intel GPU, either way it's less than a year old and the diver should be still currant? Anyways here my specs. What could be going wrong to cause the game to lag like this?

HP Pavilion Dv6t-CTO

Intel i5 460m CPU
8 GB DDR3 Memory
1 GB ATi Mobile Radeon 5650 GPU
Windows 7 64x

Thanks guys, I appreciate the assistance.

Unfortunately it's your GPU.

The CPU is fine, that'll probably run it without issue, but the GPU is way way waaaaay below the GTX260 on performance. It's actually below the 9800GTX

actually i think his gpu could handle the game. OP make sure you have the latest drivers and mess around in the game settings, too. some user had problems with his graphics which was fixed by disabling some sort of option there. might help you too.

Yeah, unfortunately it won't, that GPU is bare minimum tbh. Considering that mid range GPU's from 5 years ago actually out perform it.

i can run mw2 multiplayer on my 4650M fine on low/medium settings. mw3 is basically the same game so i don't see why he'd have any problems.

Wow really?

The 1GB Mobile Radeon 5650 in my laptop runs my other Steam games: Half-Life 2, Bioshock, FEAR 2, Mass Effect 2 no problem at fully settings...

According to system requirements lab, it exceeds all specs...?
