Performance issues gaming with wireless mouse (Logitech)


Recommended Posts

Hi!

Last year I already planned to build my 2-in-1 system to get my NAS (with Plex etc.) and my gaming machine in one case... Due lack of compatibility to the new Ryzen 3rd generation (R9 3900X) and the X570 chipset of my Asus Strix E-Gaming I gave up the idea to use unRAID for my usecase.... In the last weeks I tried it again and everything seems to work except for the mouse behaviour in games. I have the same FPS like on a baremetal Windows but my wireless Logitech G603 seems to be not as responsive like on a baremetal Windows. It is very frustrating and I tense up in my elbow :(

 

My question is now: Does this have something to do with the Logitech wireless mouse itself or is it a CPU overhead problem or something else?

(Of course the mouse is fully charged and set to performance mode in the G-Hub)

 

At first a summary of my Windows VM:

- using 8 cores (+ SMT)

- assigned 20 GB RAM

- passthrough my NVME SSD and backup hdd etc.

- passthrough all available USB controllers except the one were the unRAID flash drive is plugged in

- of course passthrough my GTX 1080

 

Here some notes which I have done so far:

- Testing with Q35 and i440f

- isolate the CPU cores which are pinned to the Windows VM

- using the MSI-Utility and check every box

 

As I am passthrough my Windows drive (NVME SSD) directly to the VM in unRAID I can dual boot and compare the results between KVM mode and baremetal... At least my XML by using Q35:

Hello, 

 

I have went through the comment and I am wondering, whether you are noticing any improvement in passing through the USB controller vs passing through the mouse itself? Also by not as responsive, are you noticing this on the desktop and out of "cpu heavy use cases" also?

Hi thanks for your reply.

 

So far I did not tested it by passing through the mouse itself because this is often mentioned to cause problems.... So I just discard this option for me.

On the desktop everything works fine, the problem occurs just in games.

I am running 3 gaming VMs 1 with USB controller passthrough and 2 with devices passed through (mouse and keyboard) and I have not encountered any responsiveness issue (with 3 cores +HT for each VM), so I would advise you to test both cases if you can. Passed through USB controller and also mouse only to see, whether it makes any difference.

Hi! So I tested it with the direct passthrough of the mouse but it seems to be even worse.

 

Sadly with this limitation unRAID does not fit my needs...

Hello, I am sorry for this, but I am honestly out of ideas. Last resort would be to try the mouse plugged in (if that is possible), however that would kill the wireless capability.... But just as a test, it could be done quickly to see, whether that could be an issue. 

 

Maybe someone more experienced would be able to come with more information or things to try. 

 

I am still a newbie, when it comes to all the things that Unraid can do, so, sorry that I couldn't help you out here :(.

Oh sorry, I thought that it is rechargeable with USB plugging possibility as I only had 1 wireless mouse (a4tech bloody r30) which was capable of wireless and wired operation, so I thought the Logitech could work the same way. 

 

Seems like Logitech only allows this with their G903.. 

 

Well then hopefully someone with more experience will stumble upon this thread :)
