In this review we'll combine two GeForce GTX 1070 Ti (MSI Gaming editions) graphics cards in a 2-way Multi-GPU setup. We'll obviously focus on Ultra HD performance as well as a micro stuttering anal... Review: GeForce GTX 1070 Ti 2-way FCAT SLI
Battlefield 1 DX12 mGPU seems quite smooth here. I don't understand how you do that I exerience massive lag spikes when enabling mGPU using 2 1080's and a 4790k?
The frame time chart clearly shows some small issues, definitely not perfect. The bigger spikes are implosions which will drag down any system really.
It's good to see some SLI review here. I think Currently SLI is for advenced 3/4K users. And 2K 100Hz+ users may feel dissapointed. Personaly I lock the framerates at 60FPS, for a TPP games use V-sync ON. For multiplayer FPP titles, I set FPS lock at 119 FPS. It gives me very low latency. And no stuttering. Minimal screen tearing is marginal side-effect. Well Prey 2017 utilise SLI very well (for me, for most) - just I need to use other AA method than SMAA 2TX. Good quality SMAA by injector like sweetFX is enough, for this very alising game.
Yes I can the see small microstutter the chart shows but on my system it runs abolutly terrible while using the dx12 API. Unbearable hitching of up to 250ms maybe even more. Switching to dx11 solves this issue but my 4790k is holding back my 1080's at 3440x1440 100hz while playing a 64player conquest match. A Solid dx12 implementation would do wonders for me.
For me in BF1 an Sli with 2x 1080ti: DX 12 = stuttering DX 11 = smooth Strange that dx12 still is a problem in mgpu in BF1
Why do you think that is strange? I'm no expert in this matter but i believe porting a dx11 title over to dx12 and coding mGPU support requires a lot of work and debugging. Probably the devs prioritys lay elsewhere. Only users who are CPU limited experience a noticable performance gain using dx12. And with quite a demanding title Battlefield, those number of people is very small.
