Sager NP5165 - frame skip/stutter in many games

hey guys.
i bought a sager np5165 in june. following are its specs -
Intel Core i5 2520m 2.5GHz w/ TB upto 3.2GHz
6GB DDR3 RAM
750GB 7200rpm HDD
NVIDIA GT555M GPU w/ 2GB RAM

there's a constant stutter/ frame-skip in games like GTA IV, NFS:The Run and F1 2011. the fps doesn't drop - it's just stuttering and it's really killing gameplay.
i have tried reinstalling the operating system, using different gpu drivers, lowering the resolution and editing texture and nvidia control panel settings, even testing the ram modules to check if either one were defective. but nothing's helped till now.
i've attached a snapshot took of hwmonitor while playing NFS:The Run, at 1280x720,60Hz.
Please help guys, really wanna play on the laptop, and am forced to play on the PS3. :/

 

First your gpu temp isn't listed.
Second 97c max on CPU is absurd. Are you planning to have your laptop burst in flames?
Probably your stuttering is due to thermal throttling. Did your laptop shutdown itself lately?
Probably you need to repaste both gpu and CPU, also clean fans and vents, maybe those are clogged with dust and stuff inside, or...are they working at all?

If your CPU reaches 97c I guess your gpu reaches high temps as well.
Your Hdd is fine? Sometimes the stuttering is due to the Hdd dyeing or a slow one.

 

my laptop never shut itself down.
and the thing is this doesn't happen with all the games - i didn't have any problems with AC:Revelations or Crysis 2.
as for my GPU, when i checked on Afterburner, it reaches a max temp of 75C - and that was for Crysis 2. For NFS:The Run, it hardly goes above 60C, and GPU utilization is in the mid-50's. yet, the stutter is there.

 

ok, this is weird -
i just checked Battlefield 3 and it runs perfectly - no stuttering whatsoever, even on high settings. but Need For Speed - The Run, which runs on the same engine, just goes on stuttering - happens at the menus, while driving - just all the time. and the worst part is that it happens on all resolutions.

 

I know Nvidia just released some beta drivers. Any luck with those at all?

 

Are you sure the games are being detected properly and running on the Nvidia card and not the integrated? If they're running on the wrong card, that would make sense why you're getting poor framerates.

 

+1 it sounds like these games are running on the integrated card not the dedicated one.

 

it's not running on the IGP. when the games run, the indicator below the speedometer symbol turns orange, and that, according to the manual, is the discrete GPU.
guys, try to understand that it's not lag, it's like a frame is being skipped every other second.
to J.P.@XoticPC - yep, tried all the drivers, same thing happens.

i just hope this doesn't happen with Arkham City. i'm getting it tomorrow.

 

I haven't loaded NFS yet, but what I've played so far (without frame skipping) have been SWTOR, BF3, and AC: Revelations. All run at Medium settings pretty well staying solidly above 30fps.

I'm running the latest Nvidia beta drivers and Intel's v15.22.52 GMA drivers. I made sure to load the intel ones first then the Nvidia if that matters any.

Also, be sure to check your game's application profile within NVControl panel to ensure that dedicated graphics is assigned and turn off any AA if its enabled.

 

@Septro - i've played BF3 and AC:Revelations, and the frame skipping doesn't happen in those games, just like yours.
What i don't get is why only certain games and not all of them lag.
I tried Batman Arkham City today, and at 1080p, with max details and DX11 disabled, there was no stutter, or frame skipping whatsoever.

 

ok umm, incase anyone is still interested in helping me out, i installed L.A Noire recently, and had the same stutter as i was getting in the other games.
i googled this up, and a user on some other forum was having the same problem as mine. he was able to get rid of it by using the command "-str" (for enabling Single Thread Rendering" in the LA Noire Launcher. i did the same thing and voila, it worked. no stutter at all.
So, could this be it? processor incompatibility? if so, is there a way to enable it for the other games?
