Stumped by FPS throttle

Greetings all, first off, i'd like to say i'm new the forums. I've been reading these boards for a few years now for information regarding various things, but never got around to making a account to post, however after trouble shooting my PC I figured it was time to ask you guys what could be up with this computer.

My specs are -

Windows 10 Home 64 Bit
8 GB DDR3 Memory
NVIDIA GeForce GT 750M Graphics
Intel i7 4510U 2 ghz non turbo, 3.1 ghz turbo

So, what i'm experiencing is a bit interesting. I'll use World of Warcraft as an example, however, this is not the only game it does this on. If i'm in a raid, the FPS will drop down to about 2 for a few seconds, and then raise back up to normal for a moment, and repeat the process over and over. This occurs in boss fights of course when a lot is going on. What I also typically notice, is that I could be sitting in a hub area and my FPS will sit at 120 for a bit, and drop to around 30, however, if I alt tab out of the game, and go back into it, my FPS goes back up to 120 for a few moments, before going back down to 30.

There is also random frame locks when things happen on screen. Like for example, in League of Legends, if a spell is cast, the frames will lock up for a split second, and resume. Same thing in WoW, except it does this not as often. Like if I target another player, or I open a menu there is a brief pause in the frames, and then it resumes like normal.


I've tried clean installs of all my drivers, i've even tried different OS's and clean installs on other hard drives, and I haven't been able to get rid of this. Lowering graphics settings doesn't stop it. While lowering it does increase over all performance (which isn't an issue) the drops still occur. i could run WoW on high with 50 - 60 FPS in a 5 man dungeon but it'll still occur, if I was running in the same inviroment on the lowest settings.

Any thoughts?

This is a laptop, and over heating is not an issue.
 
The CPU hits about 80 - 90. Doesn't get much over 90. The GPU sits at 80 in games after a few hours of game play, it'll get to low 90. Its a laptop, but its very well ventilated. I also have a cooler installed thats keeping everything pretty cool. Everything should throttle at 100 + if i'm correct.
 
I'm quite aware that its throttling, but I don't think the processor temp is the issue.

The CPU is throttling at not even 70 Degrees. The point of which this CPU Should be throttling is 100. Turned my video settings up, sat in my base for 10 min. Goes from 3 GHz to 780 MHz? 10 Min? 70 Degrees?

The GPU has ran this hot since i've bought it, which is not surprising. Its a laptop after all, and its a GPU in a laptop. It ran this hot when I got the computer, but this wasn't an issue when I got the computer. There was no stutter at all, or FPS issues.

The only thing that has changed are these stutters.

btw. PC power plan set to high performance. Its not on balanced, or power saver. Before someone comes in asking that lol
 


It throttles at 100c t junction. This is not a temp you can measure and is estimated to be around 20 above t core. You could set Max CPU and GPU speed to 80%in power settings that might be enough.
 
So you're using the same exact in-game setting's you've always used, and never had issues until now? Have you're temps always been that high as well? Also are you running Windowed or Full screen. These may be stupid questions but I was just curious.
 

I'm going to give this a shot tonight to see if it improves, thank you!

Edit: didn't help. Temperatures were lower, but it still throttled down to the same number, almost instantly when the game was launched.



No actually. I used to run everything at 1080p. League of Legends on max settings, I dial shadows down because I don't really care for them, and its a FPS boost usually. WoW at High, Starcraft 2 at highish.

Do to the issue starting up, I now run everything at 720p for additional performance (which only helps my consistent FPS, not the random drops.) League settings unchanged, WoW is now ran on Good, Starcraft on lowerish settings. Also, full screen all the way
 
I guess the only other thing you could check is right clicking on your desktop to pull up your nvidia control panel - click on global settings - and looking for power management mode, and if it says adaptive you could try setting it to the options, "Prefer Maximum Performance." Those temps as you know for any GPU at 90c is simply too high.
 


Ima try this one out for a few games of league and see if I notice anything. I don't know if this will stop the processor from dipping though?
 


I'm honestly not sure man. All I know is prolonged high heat like that as you know will start to cause failures, throttling, weird freezes and error's, screen tearing etc. If you weren't getting temps like this when you bought it than you know it's probably a cooling issue. I'm just tossing idea's out there on what I would do, and if I noticed temps like you have I'd be looking at my cooling.
 


The thing is, I WAS getting temps like this when I bought it. This is a new issue thats cropped up. Also, the settings change has reduce the temperature, but the stutter still remains.
 


Did you install anything driver wise around the time the problem started?
 


No, if I recall correctly. I've even tried clean installs of multiple drivers, nothing changes.
