Weird dual GPU issue

[pinx]

So, riddle me this.

I have a 5900X with 5700XT and a Quadro P400.

Running W10 x64 with Aster Multiseat software.
- User 1 has a 5700XT which is connected only to the LCD 1 and 4K TV
- User 2 has Quadro that is connected only to the LCD 2 and a graphic tablet.

When I run Forza Horizon 3 with User 1 on a TV , it works like dog shit - for some reason it runs on a Quadro. HOW?
Tried running it w/wo W10 GPU scheduler, same result.

This is THE ONLY game out of 40+ causing me problems, haven't tested FH5 yet.

Any idea what kind of sorcery is this?

Im guessing you are talking about a quadro P4000 and not a P400 or we are talking about very low end hardware.

It is in fact a 2GB P400, but it doesn't even matter.

 

What troubles me is how can this card output FH3 to a TV instead of 5700XT when it's not even connected to it?

 

Read my post carefully and try to imagine the issue.

It's going to be a setup issue with the Aster Multiseat.

 

If things are weird, that's why.

I've been using Aster for quite some time now, so this is hardly Aster's fault.

Besides, it's been basically flawless once I properly set it up.

 

I've read about similar issues around FH and laptops with iGPU + discreet GPU, but found nothing specific.

Also the game is from Win Store, so files are locked and can't even set a FH game profile in AMD Adrenaline.

 

Apart from FH not a single game from my Steam/Origin/Epic/uPlay collection had issues.

Horizon 5 clearly works on the right GPU as well.
