He's talking about the MSI cards that sported a Lucid Hydra chip that allowed to run cards from AMD and Nvidia at the same time. And the performance was horrendous.

OT: Ha! I'll believe it when I see it.

I never heard of it and can't imagine how this would work. Thanks for hinting me on what to Google now.

I have a question about DirectX12 in general: If a developer did not specifically make a game for DirectX12, then will you still see performance upgrades?

My guess will be that nvidia will block it somehow, just like they did when people with AMD cards were putting in small nvidia cards to run physx. Nvidia put in a software block that prevented phsyx commands getting accelerated by the nvidia card when an AMD card was present in the computer. The same thing could be done again.

You're welcome

Nope.

Thank you.

I am highly sceptical

Given how SLI performance firstly frequently causes bugs and secondly isn't very efficient, I wonder what the real benefits of this will be

Personally, I have 670 which is rapidly becoming out of date. Being able to stick a random new graphics card in there and get a boost would be nice, but I'm not sure it will really be too much of a benefit

This could be an absolute game changer if true. It would be insanely hard to implement something like this though, so I would be very reserved about it until more news comes out confirming or denying it.

sounds great on paper, but considering that even multi graphics cards set ups of the same model still have many problems (after decades of availability) I think this new system won't work that well out of the gate and devs seem to have to do quite some work for it to function as intendend aswell
