BF3 problem: low frame rates (laptop)

post #1 of 5
Thread Starter 
Alright so i recently got a Y470p and specs are as follows.
I7 2670QM @ 2.2 (up to 3.1 turbo)
8gb ram
750gr 5400rpm drive
AMD 7690m

According to Notebookcheck this card will play BF3 on low-med settings on 15" and 17" resolutions. So with the new BF3 patch i received some performance boost on my desktop and figured i'd see what the laptop could do. Well on medium i'm getting 10-13fps and with textures on medium and everything else on low i'm getting 15fps. This is all @ 1366x768. Granted this is the GDDR3 version of the card rather than the GDDR5 version but it shouldn't make that much difference.

This is my first i7 based CPU as you can see i'm still running phenom and a Q9550 on my other rig. Is this something to do with SB and hyper threading or turbo boost? Or is it just the graphics card can't take it?

i'm sure you know this, but just incase, forgive me if i sound insulting.

Make sure your charger is plugged in and its set to high performance mode.

even if its high performance mode, most laptops still cant provide the optimal perfomance while running off battery.

It is in high performance mode. Tried it with the program switching on default and then manually switched to the 7690m, same result. Didn't know i needed to be on the charger. Going to try it again.

Update: lol it was being on the charger, getting 35-40fps in single player now wow.. thanks man

EDIT: lol no problem man. ( rep is always apreciated! )


Basically what happens is, the game is demanding all of your computer power, and your battery can only put out a max amount of power, which is not enough to run your CPU and GPU at max.

So, glad you learned something, have fun gaming only 10' away from an outlet, and happy gaming.

( also, some lower end games you can probably get away with playing off the battery, but you will still not have the computers max power while under battery )

Shameless plug ftw but good on you for helping him. I'll give you a +!
