I have been troubleshooting poor performance on an XPS 9570 without much luck the past 2 weeks. Drops of up to 80% performance in games (from 150fps to 15-30fps) V-sync does not fix the issue, makes it worse. Terrible performance with Adobe video editing applications.
To answer your questions:
a) Yes exact same games, same Adobe applications.
b) AC power
c) Updated to windows 1803 (I believe this is could be the problem!) :Hmm:
d) Updated to BIOS 1.3.1 for XPS 9570 (again possibly the problem!) :Hmm:
e) Yes, I've tweaked everything to maximum and set all apps to use Nvidia GPU.
f) No faults detected. I tested with the recovery image and then updates (from Dell site) no change.
I wiped the laptop back to the factory image from the recovery partition. This didn't fix anything... even with the old drivers. It was working fine when I first received the laptop, had no performance problems. The fact this is no longer the case with the original factory image is puzzling! I suspect the recent BIOS update is the issue.
Other issues include, videos stuttering for the first few seconds or when the cursor is moved. Videos not up-scaling correctly on YouTube (You can see a pixel-like grid on 1080p and lower) When you move the cursor in full screen videos appear smoother and up-scaled. When the cursor and play-bar dissapears videos lag for a few seconds and you can then see a grid/rough edges as the videos aren't up-scaling.
Lastly both the Intel and Nvidia GPU are under load at the exact same time under the performance monitor. The GPU switching might be broken, causing all these issues. I re-installed the Intel Thermal Dynamic Platform driver and even rolled it back, but had no luck.
For the laptop to suddenly drop in performance by 5x is beyond thermal throttling. The only other explanation I can think of is a hardware fault if not the BIOS or Windows update. A number of people have reported these faults over the past few weeks.
Please send this to the system engineers/software devs so we can get this fixed ASAP!
Solved! Go to Solution.
This is indeed BIOS related. It is a very strange GPU temperature bug from 1.3.1 onwards - causing performance issues under 48 degrees. Yes, completely ridiculous! See the recent article below - it also confirms my experience running the Unigine benchmark from other posts. Hopefully Dell will finally fix it now the issue is growing...
Soooo, in the meantime run the laptop "not too hot, not too cold - just right" (seriously DELL FIX IT!)
@BroBot92, thanks for reaching out to me. I have moved your post to create a new thread as the original thread relates to the previous model of XPS from two generations ago.
Thanks for providing the information you have provided. I haven't had any reports of performance drops on the 9570 systems which makes me think this could be unique to your system. Considering that information I believe the latest BIOS and the 1803 update are less likely to be causing this.
Can you help me out with the following troubleshooting details -
a) Has the system ran fine up until the last two weeks?
b) Do you have the latest firmware update for your drive installed?
c) Do you have the latest drivers installed after you did the OS refresh?
d) If you run the system in safe mode do you still have performance issues and lag whilst watching youtube videos?
e) Can you run the extended performance tests on the system and note down the results please - https://www.dell.com/support/home/uk/en/ukdhs1/product-support/product/xps-15-9570-laptop/diagnose
Click on custom component tests and tick all 9 options on the bottom left corner under "Performance"
Have you tried disabling automatic panel refresh rate at all?
Right-click on the Desktop, and select Intel® Graphics Settings
Click on Power to access the Power Section
Under Power section uncheck the Panel Self-Refresh to disable it.

a) Yes (BEFORE THE BIOS AND WINDOWS UPDATE!)
b) Yes - I have tested with both the old drivers and updated drivers after restoring the factory recovery image!
c) Yes - as I have previously mentioned
d) Different performance issues, slightly more stable (pixel grid gone), but still choppy playback due to lack of GFX acceleration in safe mode - (you should know this...)
e) Component Test results: We did not find any issues (green tick)
f) Yes I have disabled auto-refresh under Intel GFX - made no difference at all...
As I have mentioned either the new BIOS or Windows update has caused issues with the intel/Nvidia GPU switching and possible c-performance states. Can you please contact a dell software/hardware engineer. Nothing on my side is causing this problem - it is either driver or BIOS related (PROBABLY BIOS as that is the only thing that has changed the past few weeks). The latest BIOS release was to fix coil wine issues. If this has changed the power management such as the VRM or c-states it could be causing the issue. I did disable the c-states in BIOS and again this made no difference.
I believe the NVIDIA GPU is working but the link between the intel GPU is not functioning properly. The Intel GPU is often running when it shouldn't at the same rate as the NVIDIA GPU. The performance graphs are almost matched. As I have mentioned I have tested this out with the factory image and then updated all of the drivers and still the issue is the same. It did not happen when I first received the laptop a few months ago...
Upgrading the bios will make the performance worse. Dell downgraded the GPU temp limit from 78C to 74C. It will make your GPU throttle a lot more and clock will be lower. They incorporated it in the new bios without informing the users about it.

In addition, BIOS downgrade is blocked!
That's terrible! :Surprise:
I can understand throttling to some degree - but it's soo bad that even 10 year old games can't run at a regular 60 fps on low settings in 1080p !!! what's going on Dell?
I also believe the Intel/Nvidia GPU switching isn't working, as both GPUs show the exact same use in the performance monitor. I'll probably have to return the laptop, I've tried everything the moderators have said, they've been silent the past few days - probably realised this is a more serious issue not related to the user! :TongueTied:
As for my usage. I've been running Lumion which is a 3D rendering software. Before the bios update my GPU is running at a respectable 1100mhz core clock. After the bios update, it is now running at 600-700mhz. The new bios update just made my laptop unusable. They also blocked bios downgrade and I'm already beyond the 30th day return period. If Dell does not fix this right, I'm making sure my whole company will stop buying Dell from now on and get another competing brand instead.
Yeah, I use Adobe CC applications for work. Luckily I have a workstation for my job, however when I need to edit on the go it can be a problem. Videos stutter, audio has pops and artifacts - I almost believe my old Dell XPS 9550 from a few years ago actually performed better...:Hmm:
The problem is the XPS chassis and some of the internals haven't changed over 3 generations. Components are swapped out - but the design can't cope with the demands of the newer hardware. Exactly why a lot of people said not to bother with the i9 version...
I actually think the performance downgrades are to stop the laptop from burning-out early or causing other damage. My old XPS 9550 battery started swelling after a while... go figure :TongueTied:
I may return it if the issue is not resolved or patched soon. Hopefully it's something that can be fixed through optimisation, but I'm not holding my breath. I'm in Australia - we have pretty good consumer protection laws here, so I shouldn't have an issue returning it.
As you can see a number of other people are having issues. They have also mentioned further changes made by Dell to slow down the product to unacceptable levels. A user has mentioned they returned the laptop for replacement 3 times - but this still did not resolve the issue.
If Dell cannot fix the issue and it is found to be a common fault, I will consider taking this to the ACCC (Australian Competition and Consumer Commission) for misleading specifications and releasing faulty devices that do not perform adequately - also wasting my time! Please note this is an independent branch of the Australian Government and has jurisdiction in presenting legal cases against companies and issuing fines. I may also notify Linus media group and Dave Lee to see if they are interested in investigating the issue :Surprise: it appears Dell has managed to outdo Apple in "throttlegate"
I suggest you immediately notify your manager and elevate this issue, also please see the thread below.
