Weird FPS fluctuation when gaming. Please enlighten me.

Have a look at SpeedFan (software) I think that will give you a CPU temp and workload readout during 3D gaming.
 
Oh, the problem is there no matter whether I plug the power in or not.

And I used SpeedFan before and couldn't find on-screen display function for games, thought it doesn't have one. Re-downloaded again and still can't find it...
 
Now I've checked, the CPU temperature is about that of GPU, at around 68-75C. VRAM didn't show me anything unsual there, remaining relatively constant, with reasonable loading and unloading during entering/exiting large area.

After looking at all these, right now the feeling I have is that the system somehow refuses to go too hot and forces the GPU to nearly stop working (down to roughly 20% usage). Drops in FPS make sense because the GPU isn't really working during those few seconds.

So it goes like this. Temperature is high, the GPU stop working, and thus the drop in FPS, and it all repeats again and again.

But the funny thing is, now that I have noticed, the fluctuation starts at around 68-69C, mostly, and the temp quickly drops 2-3C, repeat and repeat... but as time goes, and I'm talking about minutes, the temperature range also begins to rise, going from 66-68 to 72-75, something like that.

So there doesn't seem to be a fixed upper threshold for referencing.

Yet another funny thing, when I was playing Skyrim, the fluctuation is there when I'm in the world, but when I enter a small cell (house, dungeon), fluctuation is gone!! I stared somewhat angrily at the temp, which says 74C:mad:.

I tabbed out for a while, tabbed back in, temp at 58C, and the fluctuation is gone even in the world cell!! Of course, until after it rises back to 68C or something.:angry:


Damn. Fumbled around the NVIDIA setting, didn't do anything in particular. Damn I bought the laptop because the older one has yet another funky thing, and I got myself out of it just to fall into another.
 
Well I wasn't exactly following it because I"m not exactly free, but I'm not ready to let it die just yet...

Does anyone else knows what it is or have had problem like this before... (ranting in an empty room)
 
Have you checked CPU temps as well as the FPS drop happens rather than just GPU?

Also do you have a cooling mat? If not, it would likely be beneficial to get one, it is a hell of a lot cheaper than a whole new laptop
 
The CPU is probably fine, at around 70+ more or less. Okay maybe I'll try a cooling pad or something, with a fan underneath. I've seen that before. Maybe I should just buy one and see how it goes.
Okay thanks guys, really thanks.

The cpu isn't as tolerant as the gpu and 70 is far too high to have constantly for any length of time

Been trying to say that for a while. Stop gaming until you sort this. Reapply thermal paste correctly as shown here.

Ensure the mechanism seating the cooler is corectly installed and evenly tightened (i always tighten in opposite directions).

Also (i have forgotten if this has already been asked) - ensure your CPU core voltages are correct.
