G7 15 7588 lagging game and again running smoothly

procie will remain at its base freqency (i7 8750H @ 2.2ghz). it won't boost to 4.1ghz. i am not tech savy. I just experimented since nothing worked for me (replies from the forum comments). Since i think it is a thermal throttling issue, as the procie boosts, it'll generate heat and thermal throttling will kick in and (frequency drop to 1+ghz) and that is where the lag or stutter comes from. Anyway, if you dont use your pc for "heavy stuff", you'd be fine with 2.2ghz overall. i hope this helps

@robert1925  what will happen if I disable it forever?

Hello! I just read your post from a while ago on this thread. I am currently facing this exact same issue where I start playing a game be it an intense or non intensive, and as soon as the laptop heats up the stuttering starts. You mentioned that you got a cooling pad for the laptop so I just wanted to know if this ended up being a long term solution for you or if the stuttering came back in any way shape or form? Thank you!

IF youre having micro stuttering issues across the system, try this: https://www.youtube.com/watch?v=eiPRtXi1XnA&feature=youtu.be . Uninstallling the programs with "Dell Support Assist" in the name solved the stutter issue for me.

thanks for sharing

I'm facing same issue on my G7 7588.I found out the reason and that is we are playing game with laptop on flat surface that stopping hit air of laptop to come out and that's the reason games becomes choppy for 3-4 sec and runs smoothly for 3-5 sec,this repeats again and again.then after some observation I found out the temporary solution.that is,

Solution:- try to play game with laptop little bit inclined so that hit air can make a way of flow as dell g7 has 2 cooling fans which is beneath the laptop

I think this is manufacturing defect and we as customer have to make dell aware about this problem

Try above mentioned solution and let me know if you're experiencing the same.

Thank you.

So, anyone still has this FPS drop problem? I got even another problem and that is, my battery drains even while i'm chargin' the laptop, dunno how it's possible this when laptop is runnin' with power network. I dunno if someone was trying to check power during FPS drop, but i used Wattmeter. During the game playing Wattmeter showed me around the 150W and when i got FPS drop for the few seconds, WM showed me around 100W, that's abnormal.

This is what worked for me.

Ever since the Bios update all my games have been lagging. I first thought it was just game servers (as I play a lot of apex legends and the prediction error icon kept popping up) Turns out it was just Dell software.

What's the bug?
It is in the latest bios. And it's almost impossible to downgrade to the older one (1.3 I think) which used to work smoothly. If you do manage to downgrade that will fix the issue.

What I did? (Skip For solution below)

After using GPU and CPU monitoring software (Msi afterburner), I realised that every time the GPU temperature would hit 77% C the GPU would throttle form 100% usage all the way back to 0% -30% usage causing all kinds of game lags for a few seconds.
To fix this I increased my max temperature limit to 87% C. Since this might damage the system over time, I can see what Dell was attempting. what a fail though right?

This stopped lag in a few of my games. But not Apex legends. But when I restarted my system the lag was back forcing itself back to less than 77% C again despite the increased temperature limit (Using third party software) This is also when I noticed that my CPU temp was hitting almost 100% C while gaming (Totally unsafe) So I Disabled turbo boost in the bios settings now realising it was never a hardware issue. It was the laptop that would Throttle the GPU usage all the way down From 100% to 0-19 % percent. The system was attempting to cool itself ever 30sec when it hit 77% C and to achieve this it would cut the GPU usage completely for a few seconds making games unplayable.
I finally set the temperature limit to 76%C. And that solved it. Now there is no more lag and the Max CPU and GPU temperatures don't go over 75%.

To fix the issue just follow these steps:

1) Search for Dell Power Manager and turn up Thermal settings to Ultra Performance from Optimised. To give your fans a boost.

2)Turn off Turbo Mode for the CPU.
Just restart the PC and press F2 at the Dell logo. Find Turbo Boost in Bios settings and disable it. This will significantly reduce CPU temperature as it no longer will overclock the processor unnecessarily.

3) Download Asus GPU tweak 2 and install it. This will let you adjust temperature limits for the CPU and GPU. Once installed go into the advanced options and set max temperature a little less than 77%C ( 72%-76%) as the bug happens when it hits 77C%. Also you might see over all performance decrease if set under 70%C so I don't suggest it. Let the software always run.

That's pretty much it. Now all games will run cooler and are lag free. I have tested it on Apex legends and Starwars Jadi fallen order at Max settings and am getting over 70 Fps Consistently.

Thank you.

I had the same problem of Thermal Throttling at 77-78 DegC with my Dell G7 (7588). My games StarCraft II and CS-GO couldn't run at high settings and would stutter (Drop to 14-20 FPS from 60 FPS) even at the lowest settings. These are two very low graphic-intensive games and should definitely run super smooth(60 FPS 1080p) on the Nvidia 1060 Max Q on this system.

Huge improvement in gaming performance after I followed your suggestions! I am unsure which change is causing the near-miraculous improvement. I believe turning off turbo boost was the most important factor. ASUS GPU Tweak 2 did not have much impact for me, as my GPU temperature started to stay within 70 DegC while gaming after turning off turbo boost for some unknown reason. I don't understand how my GPU is running at a lower temperature by turning off the turbo boost on the CPU.

But whatever it be, my laptop is again usable for gaming Yay, Thank You so much!

Try this.

Gaming Performance Significantly Reduces on Inspiron G5 5590/G7 7590/G7 7790

In the Dell Power Manager, test all four options = Optimized, Cool, Quiet, Ultra performance

Mate realise that most not every one of these people are not good. This is a software issue. Your one off "never had this problem" attidue is the outlier. If its not a problem for you, just stop posting on this thread. Majority of the G7 users here are looking for a contructive way to fix this issue and your suggestions are not helping.

I finally managed to solve my problem. I sent it to a technician to do a cleaning and change the thermal paste. I bought the master gel maker thermal paste from cooler master separately. My temperatures have dropped severely and everything has returned to normal, I can play the games smoothly. Before my gpu was above 86 degrees, now it is no more than 70.

I am having same problem. 

I have been using this laptop since 1 and half year. While playing games FPS were good(60-180+ with charger plugged on). But Since this January 2021, out of no where, my FPS dropped to 60 even when the charger is plugged. And without charger, I get 40 FPS. 

I have updated my graphic drive, installed intel graphic manager, NVDIA GeForce Experience and added graphic drive into it, optimized my game setting through it, still getting same problem. 

Can anyone help?

I had the same problem, and let me tell you I really found a fix for this issue for me! If your hardware is faulty then this solution might not work for you but is your laptop is thermal throttled at 77-78° then this is for you! 

How do you know if it is thermal throttling? 

Well install any graphics benchmark app (furmark is a good one) and run stress test, during the test your laptop will start to show framedrops at a particular temperature (in dell g7 7588 it's 77-78°) and that's when you know it's a software level issue, because these machines can in theory sustain 120° temperature without crossing the safety threshold that can harm cpu and gpu (also after the solution my peak temperature was 90° without a single frame drop But i didn't stress it further) now up to the solution 

Solution:

1) Open Dell Power Management app.

2) Open Thermal Management

3) Switch to any preset

4) Switch back to Ultra Performance or any other preset you prefer 

You have to do it every time you restart your pc, if you put the pc to hibernate then no need to do this tweak the performance will be high.

That's it literally!

I don't know why this happens but somehow this app is bottlenecking the performance above 77° temperature (maybe a bug) but after switching the modes you'll get flawless performance and without any frame drop.

Here are the furmark results before this tweak:

 As you can see the temperature is stuck at 78° 

And this is the FPS during that temperature (AC power plugged in):

 Here are the results after this tweak:

 (I hope the image is visible) as you can see the temperature from the last point have been increasing to the point od 88° and here are the framerates:

 see the difference!

Conclusion: There could be 2 reasons for this to happen, 

     1) Dell implemented this on purpose to prevent permanent damage to the pc, if this is the case then I think we should not be interfering with this .But the way I think it's not the case

     2) The application itself has bug, and that seems like the reason, because as soon as you switch the presets, the performance is increased, so I think it's definitely a bug but I think I should present this analysis to some engineer at dell (which I will) and come to any conclusion, but for now if you want to stop framedrops, you should use this tweak.

Open SupportAssist and then update the intel GPU driver, or just let it update everything. It helped quite a bit for me.
