Game lagging

[Roger222]

I used to play Tomb Raider with my display link monitor, but suddenly I can't use it anymore. The game is lagging really hard.

I have an NVidia GTX card . When I play the game directly on my laptop screen everything is fine. When I play with my external monitor plugged into my Dell Docking station display link, the game is lagging. It used to work fine.

Is it suppose to use my Nvidia GPU or since it's display link, it will only use the one with display link ?

All my drivers are up to date. I'm really lost if I looking for the wrong think and I should connect my monitor directly to my laptop with hdmi or if some drivers conflict somewhere.

thanks

Hi Roger,

What kind of machine are you using?
DisplayLink doesn't compute graphics, like always, the graphics card is doing the hard work. DisplayLink driver gets the computed pixels and, through our secret recipe, ships them through USB.

However, if you are using Windows 10 Anniversary Update (let's call it Redstone) there are a couple of things... unfortunately.
1. Are you using a multi graphics card machine? If so, we've logged a bug to Microsoft on which graphics card is being used. Currently on Redstone, Windows routes the calculation for DisplayLink to the graphics card used for POST... and that's usually the low end Intel graphics card in laptops. So the solution is to disable the Intel graphics card so only your NVidia GTX is left so the OS doesn't have the choice.
Before Redstone, our driver was responsible for directing the requests to the proper graphics card, but that part is now an OS feature which will allow better stability and ongoing support in the long run, even if we are experiencing limiations currently.

2. If you don't have a multi graphics card config, would you please tell me more about the lag? Maybe you could share a video taken with a smartphone showing the comparison?

Can you also check with version of Windows you are using, including the build number if using Windows 10? This would be helpful to understand and for me to ask a developer to play Tomb Raider to reproduce this.
Actually, if you could post the zip file created by our diagnostic tool, this would help select the proper machine and install the same drivers to be as close to your config as possible...

Kind regards,
Alban

You're right. I think I have 2 display adapters and I think the bug appeared when I updated to windows 10 anniversary update (it makes sense).

My setup:

I have a Inspiron 15 7000 Series 7559. In device manager I have 2 display adapters:
Intel HD graphic 530
NVidia GForce GTX 960M

I disabled the Intel adapter in device manager and rebooted but after that, I couldn't use DisplayLink with my other adapter.

Also something strange, Windows didn't seems to use my NVidia adapter because I coudn't change my display setting and in device manager, my Monitor Location was on some generic windows drivers instead of NVidia. The resolution was also bigger.

Is there something else I need to do after disabling the intel card ?

Also, my display link is a Dell 3100 dock.
Windows 10 : 1607 build: 14393.447

Hello,

Difficult to comment, I don't know if we've got that machine around... But here is what could take place.

There are different ways of doing multi graphics.
1. Have two totally distinct graphics cards
2. Have an hybrid card but really only one path

The advantage of 1. is independence, but makes the graphics subsystem a real nightmare for everyone... The solution 2. is also a nightmare(!), but because the application doesn't really see two cards to choose from, this simplifies for the application, but makes the driver much more complex.
You may have the possibility to change your system between an on-the-fly switchable graphics or hybrid mode, have a look in the BIOS or Dell forums.

There is something strange in Windows indeed... On a desktop machine, we have disabled both the motherboard graphics card in device manager, and the additional nVidia graphics card (distinct physical cards, with distinct connectors, it's a desktop) and we can still get displays working when connected on either/both/DisplayLink only.
Do you know the name of the generic Windows driver? Was it the basic graphics adapter?

This is at the Windows kernel graphics driver level, so whatever indirect display driver you are using, with whatever hardware.

Kind regards,
Alban

Any update on when microsoft is supposed to resolve this issue ?

Same for DELL XPS 9950 with Thinkpad Dock 3. Everything worked pretty well before redstone update, now it's a nightmare. Mouse freezes for second every once in a while, NVidia GPU doesn't work at all.

I have the same issue on my Lenovo Ideapad 720S with NVIDIA® GeForce® GTX 1050 Ti 4GB

I have connected one monitor through USB 3.1 + thunderbolt, on this monitor playing the game
and second monitor connected through the DisplayLink dock on the second USB 3.1 port, mostly I use it for wired network (Ethernet port)

in the last 2-3 weeks I have this bothering mouse freezing and game lagging issue. I suspect it after Nvidia driver update, but not sure.
The problem persists until I disconnect the dock, so it is definitely something related to dock + nvidia or dock + some other windows 10 driver.

my mouse and keyboard are logitech.

Wanted to highlight again, that just few weeks ago it worked perfectly since I have a dock for more than 4 months already.

BTW. I started to have the mouse freezing issue on Ubuntu 16.04 (I have dual boot on my notebook). The same, I suspect it is related to the latest drivers updates from DisplayLink and/or Nvidia, as before it never happened.

Also, this issue may be or not, related to another thread: https://displaylink.org/forum/showth...7638#post87638

Well, if you have the Windows 10 operating system, you can try turning on the game mode. It might help you reduce the lagging hopefully.
