Two Steam accounts running on two steam clients on the same machine.

[Dj_Zorbas]

Hello there so I setup a computer for my 2 nephews.

Its one physical desktop that (with help of some software) divides 6 cores into one windows user and the other 6 cores into the second windows users (yes they both log into windows from the SAME machine into DIFFERENT windows accounts)

Each windows account is "fed" into a separate monitor, lets say monitor 1 and monitor 2 (not extended view the mouse cursor of windows user "A" can not roam to the screen 2 of windows user "B" and vise versa)

Everything works fine with stand-alone games (they both can game on the same time with two different keyboards and mice etc on their seperate and individual screens)

but with steam we face a problem.

And I want to repeat that they have two separate steam accounts (lets call them steam a and steam b)

So when windows user A logs into steam "account a" no issue.

When windows user B logs into steam "account b" though then either he cant log in or windows user A gets logged out from "steam account a"

Is there any solution?

I think that if I can somehow trick steam into logging into a separate network adapter it would work (since if instead of 1 desktop it was 2 desktops on a lan network then probably there would be no issue)

So I have somehow to convince steam that steam account a is connected using a different ip and mac from steam account b

I am not sure how to tackle this though.

The motherboard (asrock Z390 Taichi Ultimate ) has 2 lan ports.

but I am not sure how to configure them so that each windows user (or atleast steam client) "tunnels" though one of those ports and the other through the other port.

Any ideas? Thanks.

You need to create a virtual desktop for the other person.

I am not sure what you mean by that virtual desktop as in a VirtualBox instance?

That's a no go then because I will lose much horsepower on emulation plus there are going to be many issues utilizing the Graphics card etc... not worth the hassle.

The way I setup the physical PC both users get bare metal performance (each of them gets a Vega 64 GPU to run his own game and half of the cores of the i7 8700k etc)

My question is not on how to achieve this.

I have already done that (although I dont run a KVM )

My question is how to run two individual steam accounts running two individual/different steam accounts for each client.

Either do this, or run VM.

Steam runs as a singleton process regardless of how many windows accounts you have on the machine. It's not designed to be used on a multi-user system.

As has been indicated your only options are VMs. Do note the overhead of a VM is much lower than it used to be (there is native support on CPUs for virtualisation, and GPUs can be run in passthrough mode).

Probably just be easier to use something like Sandboxie to run the second client.

Sandboxie has "died" they made it freeware (I had 2 lifetime licenses, been using it for years) and is working on making it opensource, so updates will be sparse if any, there were a single update 1 or two weeks ago, but there are still problems with it on windows10.
If the system is using windows10 I'm affraid Sandboxie could result in more headache than good.

Seriously, just buy a second box.

Other than VM have you tried installing Steam to separate locations? I have it installed on let's say D:\ for my account and on E:\ for another user on this system. This way we can't see each others library or anything. Does mean Steam and games updates did to be done on a per account basis. Not trying to run 2 instances of Steam or our games though. Just to separate Steam installs depending on which Windows user is logged in and so we don't need to login and verify by changing user all the time.

I know this is 6 yrs later, but as this ever solved?

Answer hasn't changed, can't run two steam simultaneously in same environment without doing something to isolate from interacting with each other.

Can try using sandboxie, or other isolation tools, or literally use VM.
