Question RX 5700 XT for VR

[davide445]

For a VR project was looking to upgrade my rig from current GTX 1070 to a RTX 2070S.
Now that the pandemia seems to have pushed prices to insane values, was reconsidering RX 5700 XT as valuable alternative.
Was wondering how much performance I will loose in VR, even doing all the possible optimizations such as downvolting etc.

I don't know what kind of special features that the RX 5700 XT has for VR, but I think that the NV cards do have some sort of dual-rendering or dual-geometry pipelines or something, to help with VR. I forget exactly what it is.

I think might be the VRWorks framework, but you need to integrate it in your pipeline and we will not due that.

You won't lose much by going with a 5700XT, VRS (Variable Rate Shading) you do lose though. This review should help settle any apprehension about going for a 5700XT.

In Unigine Superposition it's 24% slower than 2070S...not a few points. Looking at this since will use this kind of engine.
I suppose neither OC and downvolting can fill such a gap, but till AMD deliver RDNA2 cards I didn't have a choice I suppose.

Thing is the RTX 2070 super is one class higher card and costs over $100 more. As you said prices have gone through the roof for it as well these days, so even the cheap models are going for $540, with the higher quality models going for $580 to $600.

So yeah, unless you want to pay about $150 more for up to 30% more performance in VR, though on average more like 15% difference, then your option is the RX 5700xt

Damn AMD push out this 5800 XT!
