Just started using a gtx 960 in an omen accelerator with a spectre x360 (8550u) with the supplied tb cable.

having a couple of issues:
1 - usb devices connected to the accelerator are lagging. the mouse stutter is especially bad.
2 - game graphics tear occasionally (same card works fine on these older games like age of empires HD on a desktop)

any solutions or things i am missing?

Is that a 13" or a 15" Spectre? 1) is a result of the Intel chipset/drivers used in this generation of TB3 enclosures in general, so likely no easy fix there other than getting a separate USB hub for lag-sensitive accessories. As for 2), most performance issues stem from bandwidth bottlenecking - if you're bringing the image back to the internal display and not switching from 4K to HD, or you have a lot of HDD activity going over TB3, that might seriously eat into the GPU bandwidth (especially if you have a 15" x360).

I THINK I FIGURED IT OUT.

I went to Control Panel > Hardware and Sound > Power Options > Change plan settings > Change advanced power settings > PCI Express > Link State Power Management 

I then switched "Plugged in" from "Maximum power savings" to "Off"

I also switched turned off "USB selective suspend setting" under "USB settings" but I think it was the PCI Express settings that fixed it.

I did this on the Huawei Matebook X Pro and it seems to have solved any input lag problems I had. I stumbled upon this solution by accident, when I was trying to figure out why my backlit keyboard was timing out. Let me know if this works for you!

Sadly, that doesn't work for me. Still lagging when playing games (Overwatch).

On my laptop, Lenovo YOGA 920-13IKB, i dont have "PCI Express" option under "change advanced power settings". I only have; Desktop background settings, Sleep, Power button and lid, Display and Battery.
I dont even have gpedit.msc, so i wanted to upgrade from Windows 10 Home to Pro in order to get gpedit.msc.

I updated to Windows 10 Pro, and the mouse lag disappeared... at least almost. My gaming mouse stil lag, but the HP-mouse i got from work is now working without any lag!
I also found this link: https://forums.windowscentral.com/microsoft-surface-pro-4/393034-where-my-advanced-power-options.html
I have not tested that yet, but if the mouse start lag again, then I'll test that too.

Cheers!
