AMD MultiGPU support in VR

[Yoshimatsu414]

Sooo I found a lot of discussions about multiGPU support in VR but there seems to just be an assumption about it not or not being worth it just because MultiGPU support in normal gaming is hit or miss. The thing that is making me not wanna really believe those people is the fact that I found on discussion where a guy said he was testing MultiGPU support with some AMD GPUs he had around and said it work in games based on the Unity engine, and UE4 from what he tried.

Since this is me only source of proof that is seems to work, I need some more proof lol. So I need its straight from some people that have tried. Can someone tell me if they can run a good majority of of VR games in "crossfire" since AMD's LiquidVR released or no?

I've just bought my HTC Vive a few days ago and it's like the best gaming device I've ever bought, it's amazing! But since I have a radeon RX470, there is more to be desired. I was thinking of snatching a second RX470, but I need to know from you guys if the support for multiGPU in VR is pretty widespread or not. A game I go play a lot in VR is Project Cars and I haven't played it much yet but Raw Data is another one that I do plan to play a lot.

Just getting a single RX 480 8GB would be a better option, as Crossfire is known to be a hassle with few benefits.

Single 480 8GB or GTX 1070 would be best; doing AMD CFX / NVIDIA SLI will just be nothing but an on-going issue you have to work around. A single 470 is not good enough, and you can't effective run/use your multi-GPUs in everything you do/run; it's just not going to work all the time for 100% for everything.

Whats your full specs and all overall? Doesn't seem like your PC is even VR ready. For AMD GPUs; best bet for minimum doing VR smooth enough would be 390 / 390X / 480 8GB

Or if you can swing one, a FuryX; but those do have limits cause of the 4GB VRAM.

If was going to look at something more expensive to do the job well; then GTX 1070 or 1080; as nothing bu FuryX can come close to those; but again, some things 4GB VRAM won't be enough, so there is that. I never will understand why AMD did not have better GPUs ready; but then they put out the Fury/FuryX and those being decent, but lacking VRAM.

Overall, invest in the best higher tiered GPU you can buy; don't waste your time/money with CFX/SLI of more low/mid range budget oriented GPUs.

This. The GTX 1070 is currently the best option out of the higher-end GPUs, as it offers tremendous performance for only an $100-$150 price difference between it and the RX 480/GTX 1060.

Hoping that Vega can compete. I'm not a fan of the way Nvidia handles their drivers

I have a AMD FX 8320e @4.2Ghz with 16GB of memory and the 4GB RX470.
I mean before I bought the Vive, I ran the Steam VR test, it says it it was ready and I'm in the green with everything. And like I said, games run fine BUT, all settings on low for games like Project Cars and Rawdata. The framerate is fine from what I played in Rawdata so far and in Project Cars but I want sharper and higher settings. I also bought Homebound, and my PC is actually getting low framerate in there though lol.
So you think I should go with Single GPU? And has anyone of your guys actually tried multiGPU using VR recently?

It's funny though, I had put together a PC last year that had an i7 6700k and 2 RX 480s, liquid cooled for my 4K TV but my gaming setup changed and I'm now gaming on a 1080p freesync monitor (because it's more responsive and such). So I sold it just to make a few hundreds back and l built this system since I didn't need all that power. But now that I've tried VR recently and got right on the VR hype I feel a little bit of regret for doing selling that PC lol.

That's not quite true Mossy. Multigpu works really well when actually implemented in VR. A classic example is the new Serious Sam VR titles. They render each eye per GPU to make it an awesome experience. There are plenty of benefits when using SLI or crossfire. I have and use both on my rigs.

I would have kept your old gaming rig. I use multigpu in VR (HTC Vive) and when implemented works extremely well.

Yeah I know David don't remind me smh lol...But like I said, VR wasn't in the plans until I tried it after that lol.
And yes I've heard that serious sam has multiGPU implementation in VR but what about other games? I'm just trying to see if it's worth it enough to get another GPU because truthfully, me getting another RX470 would be the moth cost effective way for me to go because I can actually pick one up another Strix RX470 locally for about 165USD If there was a few games that I couldn't use 2 GPUs in I wouldn't be that mad, but the heavy weight games like Raw Data I would like to know if it did.

[Yoshimatsu414]

Anyone able to tell my the current state of MultiGPU in VR? Like is it growing or not??

The best thing to do is post your question in the game forums that may interest you.
