Are you sure that Windows Update, Dell Update, Anti-Virus, Microsoft Store, and any other apps are not updating in the background? All of these updates occur without any warning and or indication that it's happening. And it can seem like your OS is slow.

In any case, I will try to roll back to Windows 10 1607, because I saw a lot of complains about FPS drops and stutters in Windows 10 1709. You can see a big thread here: https://forums.geforce.com/default/topic/1004600/geforce-drivers/all-games-stuttering-with-fps-drops-since-windows-10-creators-update/222/

I will also try newest RTM, Windows 10 1803. It's unbelievable, that we buy expensive hardware and have such a big problems because of drivers issues. It's embarrassing.

Even I am facing the same problem. Hope we get a fix soon.

JordyGio> Are you talking about Mouse Stutter? Mouse Stutter and freezes are caused by Intel HD drivers, and I solved that by trying a combination of Intel HD drivers - now I don't have mouse stutter or freezes. In any case, I still have FPS drops even after Windows 10 1803 Update. Also, Toshiba NVMe just su-cks hard. I still will test some games today on Windows 10 1803, I will also try Windows 10 1607 LTSB (No Windows features whatsoever) and we will see what will happen. I wanted to try to change SSD and try with good one, but I will not do that - I will go for RMA. I will send them a lot of tests: FPS, Toshiba garbage NVMe and so on. Fix it.

My issues are mouse stuffer and fps drops: now i'm going to disable the iGPU Intel from BIOS and then i'll test some games to verify if something changes.
1250€ = good hardware, bad software 

When it comes to drive performance, that's also drivers issue. I did an experiment: clean Windows 10 installation, with no internet connection. I left everything as it was, no drivers installed. And then i made a drive speed test in CristalDiskMark. Guess what. ~1000MB/s write speed. After anything installation of anything Intel related (thermal framework, chipset...) speed drops to ~350MB/s. I wonder, who should solve this issue - Microsoft or Intel?

Nothing.... i've surfed the internet for 2 hours but finally i've found out that dual graphics systems (like my pc) can't completely disable the intel iGPU, you can do this more easy on a desktop computer or a pc that allows these kind of change in the bios. I've disable the driver of Intel HD from device management but then Nvidia graphics card doesn't work anymore! You can use it, only linking your pc at another screen. For now.. i'm going to use my external 21' screen, but this Dell should be a laptop, not a **bleep**ing desktop!

And you? Can you play well with Windows 10 v.1803? If yes, i think that for next one recovery i'll install it.... and then i'm going to disable updates... S***.

JordyGio>Good luck with that, bro. Optimus FTW!...right?

DoctorRzepa>Same here - 1200+ MB/s write after clean Windows 1803 install. In any case, I blame Dell and Toshiba, not MS or Intel - just provide good drivers in the products page. That's all. Don't give any drivers, who you gave Samsung NVMe, fix our **bleep** with Toshiba NVMe, or replace Toshiba drivers with Samsung ones.

After Windows 1803, games performance looks quite good, but OS is still a little bit slugish, compared to my other, older PC with piece of **bleep** GPU, but SSD and i7 CPU. I will try to swap SSDs, if that will not help, RMA.

For stuttering, i recommend TrayPwrD3 as a workaround - it keeps Nvidia at idle, which reduces lagging in exchange for battery life.

Lixteris,

if you also experience that weird bug with NVME Toshiba drive, please join my discussion, which I started. If we can gather many users with that issue, maybe Dell/Toshiba will start working on a fix.

Why this particular model has to suffer from poor software? How long is it on the market?

DoctorRzepa>Where is it? Some dude did that, even took Toshiba NVMe from that notebook, as I recall,
sent it to Dell engineers and they said, that drive work "as indented". As I understand, they just fired up Linux, as many people in that field do, when they work with these kind of things, and saw that drive is working GREAT. When people had older version, Toshiba XG4, they used OCZ drivers to fix the issue. Our XG5 doesn't have retail version. XG5 is almost a year on the market, btw. TrayPwrD3 workaround works good, but I don't use it - latest Intel HD drivers seems working just fine as of now on Win 1803.

JordyGio>You can't use only nVidia GPU with Optimus. We don't have a option to turn off Intel iGPU. What about games? Everything runs quite good, as in Notebookcheck review, expect PUBG sometimes, but it's understandable - that game is broken anyway.

Still, I think I will go for RMA - I don't want to use NVMe with 350MB/s Write and I will demand for Samsung one. The problem is in the XG5 firmware and Dell motherboard, because that NVMe looks great in reviews.

Games run very well, but without Intel HD driver and with another monitor to use Nvidia dGPU.
And i can't play everywhere if i always have to take an external monitor with me!
In fact, this is a momentary setup...   i hope that dell can resolve as soon as possible.
