Multi-GPU support

[Hogdriver155]

So does it finally work or no? Only support Nvidia? Or...? I have a 295X2 and I'd like more than 10 fps in 4k.

you could force sli/crossfire with a small gain of performance.

but it is not worth the trouble and problems regarding sli/crossfire

Weird that no other games have issues with SLI or crossfire, 60+ FPS in crysis 3, battlefield 1, etc.

Does it only work in DX12 or what because I'm on Windows 7? Or does it still not work at all with this game (still?)

These are finished games with different engines than ark.. The unreal engine 4 doesn't support sli. Any UE4 game natively doesn't support multi gpu..

Also I wouldn't recommend you to play an unfinished game in 4K.. It's not even possible to get a constant 60fps on 1920x1080 yet


Also: dx12 isn't even in the game yet but win10 gives better performance in general

[Acandri]

the game does not support dx12 (and with this multi-gpu) but, like i said, you can force sli/crossfire with the usual downsides/problems but only a small perf gain

I read posts from 2015 or 16 that said it would support DX12 when Windows 10 came out...

Well, it's here, where is the support?

Should I just get a refund now?

There are a lot of games out that do not support sli/crossfire. This game uses UE4 engine which means it cannot support sli/crossfire properly. Sli/crossfire use alternate frame rendering which means while one card works on one frame, the other is working on the second frame. UE4 uses a technique called deferred rendering. Each frame that is drawn requires information from the previous completed frame to render. So the game cannot be rendering two frames at the same time like AFR does in sli/crossfire because it has to wait for the previous frame to finish before it can start on the next.

This is interesting and useful, thanks.

Well these developers really enjoy to delay things and use advertisement for their advantage to get even more copies sold. Dx12 is still in the "upcoming features" section. They probably haven't even started working on it since 1 year

I'm pretty sure the problem isn't in wild cards control at this point. As previous posts have indicated, the bulk of the problem is likely with the boys at epic and the unreal engine.

I wouldn't get your hopes up much even if it is supported though as it's all down to low level programming, how well we will benefit and no 2 games are created equal with that regard.

lol, what a joke of a worthless opinion, which is all that is. On haters opinion, no facts.

[WizeKrack]

Well I thought the benchmarks seemed worth noting, while his opinion may not have been worth much.

Don't get me wrong as I'd love for dx12 and or Vulcan to show large improvements. It just doesn't seem that they are there yet for anyone, not just WC. Aside from Doom and AOS are there any other examples showing performance increases?
