Throttling Issue?

Technical issue here: My MSI fx600 (i3, geforce 325M) has, since about 2 months ago (owned it since december), had a problem where, after playing a game for 3-20 mins (depending on the game) the framerate drops to 2/3 fps and only stops if I exit the game or if I alt-tab out (after which the problem returns quickly). 

 

I was told that it could be the CPU throttling itself - but it never used to do this, and throttlestop says the cpu doesn't even reach the throttling point (~90 deg C). So I think it may be an issue with the GPU. Anyone else has a problem like this?

I would try a system restore first, and possible using a notebook cooler?

cheers ...

It's not an overheating issue as far as I can tell - it's some problem with the GPU misbehaving, and I don't have a restore point that goes back 2 months.

I meant to restore it to original state.

Well, I've tried using the drivers supplied with the laptop, with effect; all other things eg. BIOS version, chipset drivers etc are the same, and I don't see how unistalling everything will help...

Hard to say what happened - thus my recommendation is to re-start fresh

Mine just started happening a long time ago too. If you have fan control somehow on MSIs, you should turn that on. I 'think' it's a limit of the northbridge chips which are causing chipset throttling. You might be able to use throttlestop to fix that, I had a talk to the creator of throttlestop on here a while back about that kinda stuff, so his word on it is better than mine (though he was able to get my laptop way past spec for overclocking so I'm pretty sure he knows his shit)

The throttling for sure is cpu or chipset based, I use RMclock to monitor my clocks and my 'real' throttled clocks that no other programs seem to tell me.

I partly fixed it by running the fans on full and just keeping shit clean, maybe you should clean her out and see what happens?
Also adding some arctic silver on the northbridge cooling would help too. Undervolting might help a little too.

I know, never happened before but it did creep up on me too somehow...it's not permanently fixed for me, but it's a hell of a lot better than it used to be, now it only throttles when it should (aka gpu hits 99C).

Hopefully yours is driver based gpu throttling or asking the cpu to limit it's clock and you can just find the right driver to fix it, haven't done any driver or windows updates recently?
