Doom 4 GTX1080 SLI Performance Issues

[Five.Stars]

im not arguing here, but its pretty common knowledge that Doom was not going to support SLI as its openGL.

MUltiGPU really is in the developers hands right now.

1. Developers have to code their frames so their not dependent the before/next frame which means Nvidia Can create SLI profiles for.

2. If developers do not do 1. Nvidia cannot help & its up to the Developer.

3. then you got Ms pushing their unified platform which Developers could love, creates a bigger market for them to use & possiblity of easier ports from Xbox.

So Hard times ahead, i always beebn a SLI/Xfiore user since the Nvidia 280GTX, however i really hope developers stay on DX11 for much longer till they have the real skills to Support MultiGPU. DX12 has some benefits but, their not night & day like SLI/Xfire Vs no SLI/Xfire

Yeah mate, have read bits and pieces about the rendering techniques that are incompatible with SLI/ CF. Inter frame dependency I think was 1 such technique.

Also with the changes to API's meaning devs are more in control as opposed to Nvidia/ AMD at driver level, then it doesn't bode well for immediate future of mGPU. Perhaps time for the GPU manufacturers to go back to drawing board and redesign how mGPU works so that it is less resource intensive for developers to code for. Perhaps not an easy task obviously.

But people wont buy more than 1 gpu if it isn't going to work properly in a lot of games. Simple as that.

To top things off...

Total War Warhammer... SLI bumps up performance about 50% but flickers enough to give someone without epilepsy a fit.

Rollercoaster Tycoon World... 10% boost in performance, so practically pointless.
