Dell XPS 15 9560 low fps / lagging

Hi loonz777,

Thanks for posting.  Apologies that your system is not performing as expected.

Here is some information from the Dell knowledge base you may find helpful:

Troubleshoot Slow Performance Issues on a Dell PC

An explanation of why your Dell PC is running slower over time and how to speed it up

Exact same problem on my XPS 9570. 

Robert can you please check with an actual engineer or software dev. Something is really messed up with the firmware/drivers or hardware. The response you provided is generic as it gets. Really appreciate if you could do this. Thanks

Same issue here on two XPS models. I have the i5 7th gen with 8gb of ram and I get a solid 80-100 fps for the first 5 minutes of gameplay before it drops down to 10 or below. My friend has the i7 with 16gb and he has the same issue. My PC is one day old. 

Hey guys... You should do some research into Intel dynamic platform and thermal framework.  The computer ships with software that runs to keep your legs cooler if the computer's case gets too hot.

I was SO FRUSTRATED before because this is a freakin nice machine!

I have an XPS 9650 and I disabled that software at MY OWN risk.

I love the performance now. Fortnite at full epic settings. I was flabbergasted.

Lets see if I get marked for spam again LOL

Hi Heath-Nay.

The problem is the laptop had no trouble before. I believe the recent BIOS 1.3.1 update or Windows 1803 update caused it. Also I can set all of my games to the lowest settings and the problem still persists. 

For me, it started when update 1703 came out. My computer was freaking out and wouldn't keep the update. It literally did the same update every day and seemed to roll back mysteriously.

It seemed like my whole system went to **bleep**.

Eventually the latest updates took but the performance was still a nightmare.

Just last week I finally disabled the services I mentioned and it is the ONLY reason I'm in this forum because SO MANY PEOPLE have this same issue and this has been the only thing that worked for me.

Yeah exactly the same reason I joined this forum.

Hopefully if we make enough noise someone at Dell will patch this soon.

On another note, has anyone noticed choppy/pixelated YouTube video playback for the first few seconds. Also when in full-screen the videos don't scale properly, you can see a grid of pixels on video 1080p and lower...

If you move the mouse when in full-screen the videos magically upscale and the pixel-grid disappears. When the cursor and playbar disappears the videos get choppy and become more pixelated due to the lack of upscaling. 

Again this is probably an Intel/Nvidia GPU switching and power management problem.

Any updates Robert?

You can see a number of people are having issues on the forum.

As mentioned I believe this might have been caused by a recent Windows or BIOS update.

This has been an issue for me in some capacity for most of the time I've owned this laptop (I got it in January). An actual answer would be fantastic

Running an XPS 9560, purchased (6/2017), fully updated & virus/malware free - experiencing the same lagging in Chrome and Firefox.

Tried contacting Dell support, their official response is: "the basic warranty does not cover assistance for this particular issue." ... I am still under warranty (I extended the basic hardware + accidental damage) but strangely they don't seem to feel their own driver malfunctions are part of the hardware warranty. Service representative _GGNShivaditya_839302  offered to charge me "$129.00 + tax" to solve this issue. Thanks, I'll wait for the patch that should be issued for free.

Any / all suggestions for a solution would be greatly appreciated.

Here's an interesting observation from Steam.

If you enable the FPS counter in Steam, most of my games set to medium at 1080p will show 80-150 fps.

However this is WRONG, the actual frame rate is soo TERRIBLE games are often unplayable (probably around 15 fps). The laptop is plugged-in, power-plan on maximum performance, applications set to use Nvidia GPU.

As mentioned I believe this is a driver or BIOS problem regarding INTEL + NVIDIA + Thermal dynamic platform. The Nvidia GPU doesn't actually have an output. It sends rendered frames to the Intel iGPU to be displayed on the panel or via HDMI. A number updates from a few weeks ago could be causing problems between both GPUs, either causing a bottleneck or incorrectly switching to the Intel GPU for rendering.

I have factory wiped my laptop to the recovery image/partition, tried it with the original and then updated drivers, ran diagnostic tests, tried different settings. No luck. Also having problems with video playback in Chrome as others have mentioned.

My XPS 9570 is only a few months old, but I believe this could be a problem across most of the XPS 15 line with the recent updates. I also had an XPS 9550 a few years ago, and didn't experience issues like this... If someone at Dell could please let us know that they are looking into the problem - please do!

I've run a number of benchmarks including UNIGINE Superposition on the XPS 9570 - probably a similar issue. I set it to 1080p, high settings. The GPU was stuck at 800MHz for the first minute and it was rendering at about 5fps, GPU temps 45 degrees C. After a while it suddenly boosted up to 1600 MHz with the frame rate running at around 35fps (much more normal for a 1050ti Max-q). Temps 70-74 C. Either the drivers/BIOS or something else is borked. I still can't work out what it is...

Notice the temps and 100% utilisation below? How is it that the card is maxing out at 47 degrees C in a benchmark? Score should be around 5000.

Plugged in, Power plan set to high performance, Official drivers up to """date""" according to the Dell website. Preferred GPU set to "Nvidia". Clean install from the factory image partition a few days ago...

PLEASE FIX THIS DELL
