    hahahaha, i was going to write, Nvidia will disable all of its features in a driver if an AMD card found same way they did with physx, so it will never work from business standpoint.

    However, according to Multi-GPU from different brands, Lucid Virtu MVP did that on top of DX11 but unfortunately it was not widely adopted by people, but now since its embedded inside DX12 then we can assume that this is finally going to be adopted by everyone.

    Like Lucid's solution, this will be to help Intel integrated chips work with a discrete GPU. Not having discrete AMD and nVidia cards in the same system as the article suggests.

    I suppose it could be a bit of free power if your Intel CPU had its graphics running alongside the graphics card. Would allow for some of those special effects on GRID games only available to intel graphics.

    Re: Report: DirectX 12 can aggregate GeForce and Radeon GPU power

    I wanted to try Lucid Virtu MVP but was put off by the possibility of having to pay additional charges to get it and then not knowing what sort of results to expect, that and the issue with Lucid not support multi GPU installations, which would have created problems for me at the time as one PC had a 6990 and the other had 2x GTX580 cards.

    You're confusing two different things: Lucid Virtu, which was targeted at allowing dGPU adn iGPU to work together (i.e. you get the power of the dGPU without losing QuickSync); and Lucid Hydra, which was a chip that worked in addition to DX API call interception to distribute the workload between heterogeneous GPUs.

    Re: Report: DirectX 12 can aggregate GeForce and Radeon GPU power

    Lucid was terrible. At best it did nothing......otherwise it caused me screen tearing and occasional screen anomalies....a mate actually had it fill every BF4 map with trees to the point where he couldn't see anything bar the trees!

    I'd stay away, especially if you have to pay a fee.

    The main use I see for this going forward (especially in multi-GPU-vendor systems) is to perform OpenCL/Direct Compute on an iGPU or second dGPU

    Perhaps DX12 will kill Physx indirectly, although I am sure nVidia are already thinking of ways to keep it going.......

    So for my next build with DX12 I'll be buying a motherboard with 4 slots for graphics cards and then ill buy an APU and 4 low/mid range graphics cards and those five should work together wonderfully? right?

    Re: Report: DirectX 12 can aggregate GeForce and Radeon GPU power

    I can see it may work nice combining intel cpu graphics with gpu graphics, especially in portable devices. They could use mobile dedicated graphics with the CPU graphics to improve the output. But given how Nvidia and AMD are competitors, I do not see them working together well (my thoughts are that the best functions will in some way be disabled if the dedicated cards are able to be combined - in a attempt to promote the sales of the same brand gpu cards for multi gpu set-ups). Although, it may help improve sli OR sroosfire (like mine) setups to work better.
    Will just have to wait and see the final product and how it works. We have all seen the difference between pre-sales hype and the actual released product. I will look forward to reading reviews and test results on this when they become available. And quietly hope that this works

    I'm just going to say: you shouldn't be excited about anything until you see it work. Hype is also usually created by pointing out just the "pros". I say wait for the "cons".

    Will DirectX 12 be lighter than it's predecessors?

    Re: Report: DirectX 12 can aggregate GeForce and Radeon GPU power

    I'm wondering if Nvidia are going to put the nix on 2 750Tis working together, after all lack of SLI is a 'feature' from a market segmentation viewpoint.
