Suddently slower performance and fps drop on my XPS 15 (latest version)

Hello,

I'm writing to you because i got some issues with my XPS 15.

Let me explain you the issue. When i bought my XPS 15, all was perfect, no issues. I started to play a bit, in-game the fps was perfect. I was at 100+ fps on HIGHEST Graphics Settings, in fight zones it was at 90 fps minimum (witch is really perfect).

Then my university exams were getting closer, and i decided to delete all my games on PC and start studying a lot more.

After the exams i re-downloaded some games, then i figured a huge fps drop. From the initials 100 fps it dropped to 35 fps (on the LOWEST graphics settings), it was going to 3 fps (in fight zones, witch is unplayable).I prefer notice you that i tried to do all in-game related changes. Then I started to search some solutions for that issue on google.

I tried a lot of things, like :

- Re-installing the NVIDIA Drivers (Clean mode). I even tried to run on "old" driver versions (i tried to run on the Nvidia Driver that can be downloaded on Dell Support Page).

- Uninstalling GeForce Experience

- Uninstalling some bloatwares

- Reinstalling games

- Reinstalling the system at all

While i was searching for a solution, i found a guy had my same issue on the same laptop (here's the link if u would like to check it out). But in his forum discussion he put that, the pc in addition to a hige FPS drop was getting slower generally.

And i could notice the same double issue. In fact, my pc was getting much slower than it was (the startup was a little slower, but opening any game : was really SLOW. Like if i click a game (17 sec min to launch, compared to 3 initial secs), file explorer (at least 4 secs, compared to 1 initial sec), firefox i was "waiting" for it for at least 5-6 secs. When i just bought the PC, it was 1 sec max.

Then i tried other fixes :

- I disabled a lot of software on Startup

- I put Battery Power Options to the Maximum (High Performance)

- On some forums it was written that my wifi connection could be the problem (related to FPS), so i bought a Dell USC-C Adapter and a NEW Etherent Cable cat6. Witch made me boost my Internet connection (even if before it was excellent too).

The Graphic Card i got is an NVIDIA GEFORCE GTX 1050. On games i was playing, it should be even "too much". Because i don't really like new games, so i play at some old games (better saying, at old "versions" of new games).

The thing i can't understand the most is, that i done no changes on the PC until i discovered that FPS Drop. At start i was even thinking : "maybe it's just today, it will be better tomorrow", "it's not an issue based on my new XPS 15 that i paid 2k euros". But then after 1 week i couldn't believe in it anymore.

That's why i decided to write this down, and try to get some help from the DELL tech team.

I rather let you know, i'm open to do any tests on the PC, anything it should be necessary.

Thanks for reading, and i hope there will be a solution for my issue that u will be able to find rapidly.

L.B.

What helped me was the preinstalled "Dell Power Manager" application. "Thermal management" tab. My setting was "Optimized" and apparently that is the problem, because about every minute for several seconds it tried to decrease heating/processing power which caused terrible slowdowns in 3D games. So, my solution is to set it to "Ultra Performance" setting whenever I am about to play a 3D game

Hi,
Actually, i found the solution to the issue.
Basically i had to chnage the MotherBoard of my PC.
To do that, i called the DELL Customer Support, we fixed a date, the tech came to my house and replaced it.

The issue might be caused by the CPU or GPU.
To determinate witch one is making trouble, you can make some tests.
Just look your CPU and GPU usage with no apps, while running 1 app and while running 3 apps. Test with some heavy usage apps, like some videos, run a game (and always be sure to run then on thw NVIDIA graphic card).

In my case, the CPU was making trouble, it was stacked always at 0.78 Ghz, witch is pretty slow, in any situation (0 apps, 1 app, 3 apps).

Thanks for reading, hope it will help.

Hey Did you pay for the motherboard? If not how did you get dell to replace it without any troubleshooting or HARDWARE TEST ERROR report from their installed software. Please help me out as I am facing the same problem.

Hi Copper,

I have the same issue on my XPS 9570.

I believe it might have been caused by a windows/BIOS update.

Hello everyone,

I bought a Dell XPS 15 9570, just 5 months back in June/July. And until the first week of November, it was working great.

One day while running benchmark tests I noticed the multicore performance was very low. Upon checking the task manager, my processor utilization wouldn't go above 60-70%. In multicore applications, once my processor utilization went above 35-40% my clock speeds would drop down to 1.5-1.7Ghz and never increased causing slow applications and task execution.

I reset my computer twice(once without and once with deleting the files) but to no avail.
My cooling policy is set to active but my fans are just not running maybe dell changed the cooling policy in the BIOS 1.5.0 update. But on testing the ESAT BIOS testing utility my computer was working fine and in its processor stress tests my fans were running properly. 
Running the performance test section in the custom diagnostics of the dell support assist application detects no errors but Cinebench R15, as well as User Benchmark, show the problem(results below).

Test Results:
1) User Benchmark: 
                                a) Overall this PC is performing below expectations (26th percentile). This means that out of 100 PCs with exactly the same components, 74 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
                               

                                b) Processor: With a good single core score, this CPU can easily handle the majority of general computing tasks. Additionally, this processor can handle very light workstation and even some very light server workloads. Finally, with a gaming score of 57.6%, this CPUs suitability for 3D gaming is above average. 
                                Actual Results: 
                                Intel Core i7-8750H
                                 36,282 User benchmarks, average bench 84%
                                 U3E1, 1 CPU, 6 cores, 12 threads, 
                                 Base clock 2.2 GHz, turbo 2.5 GHz (avg) ~ the turbo average look at that
                                 Performing way below expectations (10th percentile bench 56%):
                                 Single core score: SC Int 116, SC Float 124, SC Mixed 122, 97% 121 Pts ~ Single core is ok
                                 Quad-core score: QC Int 417, QC Float 258, QC Mixed 223, 68% 299 Pts~ Look at this
                                 Multi-core score: MC Int 288, MC Float 324, MC Mixed 306, 46% 306 Pts ~ Look at this

                         c) SSD: 97.9% is a very good SSD score. This drive is suitable for moderate workstation use, it will facilitate fast boots, responsive applications and ensure minimum IO wait times.

                          d) RAM: 16GB is enough RAM to run any version of Windows and it's more than sufficient for nearly all games. 16GB also allows for very large file and system caches, software development and batch photo editing/processing(RAM slowdown has also occurred due to slow multicore speeds

Earlier the overall score always used to be always above the 93rd percentile

2) Cinebench: 
On battery(max performance mode): 348
Power cable plugged in(max performance): 395(just a slight increase)Screenshot_2.png

 As quoted on https://www.notebookcheck.net/The-XPS-15-9570-with-i7-8750H-CPU-is-almost-twice-as-fast-as-its-prede... the score should be around 1050 points, not 390 which is pathetic

Cinebench is a multicore benchmark test still my processor utilization would not go above 60%. It hit 100% first and then in an instant dropped down to 55% and stabilized there. Also look at the clock speeds this is on max load

On reading this dell community forum query on this link: https://www.dell.com/community/Laptops-General-Read-Only/XPS-9550-Always-Slow-Performance-again-the-...
It says that the motherboard has to be replaced. But I am not at the USA right now I'm in another country at the moment and will be here till the next August because of my work demands and unfortunately, I don't have international warranty.

What should I do? I cannot afford to spend on another laptop as my config already cost me $1500. Anyone who can provide any valuable suggestions and solutions please help as this is my brand new laptop.

Note: On running single core tasks the results are just as good as before it gives the same max clock speeds of above 3.6Ghz

Hi, Employ these steps.

 

(1) Set Dell Power Manager profile to "Optimised". Windows battery profile to Best Performance.

(2) Disable speed step in BIOS. Stick to BIOS 1.2.2 if possible.

(3) If you have Intel XTU installed, revert all settings to default and uninstall that pos software.

(4) Install throttlestop (if not already done), and enable Intel speedshift + EPP at "0" (Zero). Ensure that turbo boost is not disabled. Disable speedstep in throttlestop. I suggest setting it to "0" when running intensive applications, and setting it to "128" otherwise.
