650M sli and Battlefield 3

post #1 of 7
Thread Starter 
Hello guys,

I bought a laptop a few months ago and I havn't been able to play Battlefield 3 on it. I can play Skyrim with mods at high/ultra settings and get 50-60 frames, starcraft II I get 60+ frames but when I run BF3 I can't run it on low settings with frames higher then 40ish. I feel this is absurd. My laptop is Lenovo Ideapad Y500 - 650m Sli, 6gb Ram, i5 3230M @ 2.6/3.0Ghz running at 1080p

running the latest drivers. Does any one know what could be the problem to this? Thanks a lot guys!

Most likely the dual core mobile i5.

Yea, that's something I thought of. Might be bottleneckled :/ But I wasn't sure.

As we can see, amount of threads trumps raw clock speed. 4 cores running at 2ghz has no problems whatsoever, but when running 2 cores at 5ghz, massive spikes appear, dropping the framerate down to as low as ~20. Yes, the framerate is higher on the 5ghz run towards the end of the bench compared to 4 cores 2 ghz, but same can be said with the 4 core, 3,3ghz one.

But what about the 2 core, 2ghz one? Average fps of 68. If we removed the dips which all the 2 core runs suffered, we would probably hit around 70+ average. Even when severly crippled, it manages to push out enough frames per second. And remember, this is in Windows too, with massive overhead. Just think of the performance-gains we would have if we had direct acess.
While AMD's IPC is lower than Intels, I refuse to believe that 8 cores running 1,6 are slower than 2 cores at 2. The CPU is NOT the problem. Don't judge the unreleased consoles based on pre-alpha software.

That's a good graph but I'm on a laptop. I think that's not the same as the normal 2500k. Also, I can't overclock the CPU without modding the bios and stuff.

The point was the spikes when running on 2 cores, no matter the clock-speed wink.gif

Ah I see.... I did some testings and my I5 is totally bottlenecking the 650m sli in Battlefield 3. The cpu is 2 cores, 4 threads at 85-90% while ingame but the cards are between 40-70%. Atr high and low the cards remain at the same usage. but the CPU is working hard. I really think it might be bottlenecked.

I ran other -so not cpu intensive- games and they play just fine. 60+ frames at high-ultra settings.
