Under Windows 10 and DX12, Multi GPU support is handled by the OS not the driver.
You need a game that support tri-Multi GPU. It's just Multi Gpu but tri-Multi Gpu for your understanding.
What games have you tried?
Have you had communications with the developers of the games?
Hi all. My games are:
- 3Dmark time spy - 295x2 + 290x = Only work master core of 295x2 ------------- 295x2 only (290x disable) = 295X2 Works fine 2 cores
- Rise of Tomb Raider - Same like Time Spy
- Deux ex Makind Divided - 295x2 + 290x = Only work master core of 295x2 --------------- 295x2 only (290x disable) = Game dont start :S
- Battlefield 1 - 295x2 + 290x = Only work master core of 295x2 --------- 295x2 only (290x disable) = Only work master core of 295x2
Hope understand me. Directx 11 versión of this games Works fine all cores (Tri-crossfire).
As already mentioned, DX12 Multi GPU support is an OS issue not a driver issue. There is no troubleshooting that can be done do support a feature the OS does not.
Hi and thanks for reply. But for example Tri-crossfire WITH IDENTICAL CARDS Works perfectly. Look at this video:
That guy use 3 R9 290 (Three physical cards), in video descripción say this:
Spero che questo video arrivi tempestivo dato che la patch di Rise of The Tomb Raider che supporta DirectX12 e multi-GPU e' uscita solo qualche giorno fa.
Finalmente possiamo vedere queste DX12 all'opera! Per tutto questo tempo ci siamo chiesti come sarebbero andate, se i giochi avrebbero supportato il multiGPU oppure no (e se AMD avrebbe avuto davvero qualche vantaggio). Ovviamente manca il framerate on-screen ma i grafici in Afterburner parlano chiaro: 60FPS bloccati e tutte e 3 le GPU stanno lavorando... A giocarci mi e' cascata la mascella, spero che il video renda ma da vicino vi assicuro c'era da piangere per la commozione... non sembravano neppure 1080p...
Eravamo spaventati dal fatto che con le DX12 il multiGPU adesso e' a carico degli sviluppatori.. (ma perche' poi prima no?) e adesso il primo gioco che le implementa fa questo miracolo... (ma non temete... adesso arrivera' Ubisoft e capovolgera' tutto)
Adesso una sommetta possiamo tirarla...
Is not a Tri-crossfire problem from SO, is a tri-crossfire problem from driver (I think). The problem seems that it is of tri-crossfire with different cards/Adapters :S.Look at this results in 3Dmark Time Spy with 4 290x (four physical cards), Works perfectly all cores:
A guy from Guru3d say this:
me, I have done it multiple times. I created this thread 7 months ago, I have
reported this issue to AMD at least three times since then, they simple don't
care. They could easily just say Linked-node mode is only for 100% identical
GPUs and the fact that they do support CF for non-symmetric setups in DX11 is
just a courtesy from AMD which is not going to be repeated for DX12. Even if I
was in their management team, I would probably not spend any manpower fixing
such an issue that affects such a small minority of users.
Hope undestand me again, my language is not good. Thanks

It does not matter what forums links say, the fact remains the same.
Under DirectX 12, MultiGPU support is handled SOLELY by the application/OS, not the driver.
Ok thanks. But, why multigpu Works in directx 12 with identical gpus (3 or 4), and not for differents cards like Directx 11?. 295x2 are two 290x in a one PCB, dont understand that not reconigze like a 3-way crossfire . Thanks
Win10 does not support Tri-Xfire with different GPUs - as already mentioned here this is not a driver issue! You have to complain to Microsoft!
Win10 no es compatible con Tri-Xfire con diferentes GPU, como ya se mencionó aquí, este no es un problema para el controlador. ¡Tienes que quejarte a Microsoft!

OK AMD sold this hybrid crossfire saying it would enable us to mix GPU's yet with the arrival of DX12 there is NO support for "hybrid crossfire" systems in DX12.
This sounds like mis-selling to me as many like the OP and myself bought extra GPU's and now we are denied the use of them, FOR GOD'S SAKE AMD sort this mess out you COULD have keps crossfire in your hands but instead handed it out to OS and Games producers who have NO INTENTION of implementing it...
THANKS A BUNCH FOR LEADING MYSELF AND OTHERS TO WASTE OUR MONEY ON THINGS WE CANNOT NOW USE!!!!!!
Once again, Multi GPU support under DX12 is handled by the Application and the OS, not the driver. This has nothing to do with AMD denying anything. The driver cannot do anything that the application/OS is not capable of providing.
You can put pressure to the people it concern to implement it. Yes?
No, we cannot.
