FPS keeps fluctuating DELL 7577

Listen its prob this issue. I have had many issues with this POS. They all seem to go back to thermal issues caused by BIOS. Dell doesn't know how to make a laptop as usual.

Anyway set your "maximum processor state" in power options to 99%. This fixes most issues and causes another. 

Now you wont have any therm issues. Now you'll be running at 2.1 GHz instead of 4.1 GHz because 99% turns off turbo boost. So enjoy reduced frames at speeds far below what you paid for just because dell as usual doesn't know what they are doing. it took me 15 years to buy another dell after I bought a another POS dell laptop 15 years ago. LAST TIME I DO THAT! 

Yep I've been having this problem particularly in bfv, for me it's def throttling. I play with someone who has an Alienware laptop who has none of theseissues I really wish I had gone that root now...

Well, I have came across this solution too (although I have to turn my maximum processor state to 87%), but I can still squeeze 50 to 60 fps on games like PUBG or Apex legends with rare moments of it dropping to 40 fps. I am just happy there are no more sudden fps drops that ruin the whole gameplay. If anyone else is experiencing performance drops due to GPU spikes, just try to adjust "maximum processor state" until your GPU usage during gameplay only comes close to 100% or reaches 100% but does not drop your fps. You can find this option by typing "Edit power plan" in the search bar, from there you should click on "Change advanced power settings" and then find "Processor power management". Just try to find what works best for you (like I said, mine was 87%). It may be not the best solution and it is possible that you will drop a few frames, but it is still better than nothing :). I also undervolted my CPU (i5 7300HQ) to -130mV, but this may not be necessary. Well, good luck, hope it fixes your problem, any feedback would be awesome! :) 

okay guys after using this laptop for almost 2 Years , i have got 1 Replacement of Whole Motherboard.

Process Maximum Rate i have tweaked it to 99% now , has some improvements , has a Coolpad too it works fine.

But yes this laptop is Bummber by Dell Guys they added nice components with very bad heat syncs you can't help it guys its a wastage as its something u have to deal with otherwise every other task it kills it but when its about processing/rendering/gaming. Heat Kills the performance.

Another Inspiron 7577/GTX 1050 user here, have encountered same stuff.

In games like Apex or Overwatch, after 5-10 minutes of active gameplay, laptop starts this horrific stutter/low FPS, and generally is hot like crazy. My main guess now: reason for that is overheating and thermal throttling, with CPU being the main culprit.

Issue seems to be mitigated to some extent by:

* Better air flow under the laptop bottom (i.e. go construct\buy some sturdy and safe cooling structure)

* Undervolting/underclocking CPU, and of course disabling any kinds of Turbo Boosts for CPU. I'm trying small ThrottleStop .exe-app for that now, and it seems to work well.

If issue persists, I will absolutely go for replacement of the thermal paste. From some other thread about this issue, I recall that someone said he was very surprised about how bad paste looked just after 1 year of laptop use.

And of course DELL laptop constructors/engineers deserve some shame for this. DELL tries to present itself as a good reputable brand. For the money we pay, we, consumers, should get a good cooling/heat-dissolving tech, not this miserable and confusing situation.

I was having this problem too, I tried everything but it didn't fix it. The last time I saw the screen turning off while testing the RAM, I took it to the repairman, he said there was a problem with the data buses, he bought 90 dollars and he solved the problem.
