    I am looking at the Newish Samsung Oddessy Plus VR Headset and have some questions as to the state of GPU's currently in regards to upgrading my 980ti. Are there any useful or potentially useful VR feature sets in going to the 1XXX GTX or even the 2XXX RTX series of cards? I am thinking that a 980ti to 1070GTX to 2060RTX / 1660 are all pretty much equal in terms of raw power. I cannot find very much info on what kind of new optimizations might exist in the architectures that would allow for a better experience vs say just raw horsepower. I suppose the second question is if considering the used market at or below $500 would the raw horsepower of a 1080ti out pace the 2070RTX.

    The reason I am asking is that while generally pretty spot on I think I have had the 45fps wall / re-projection thing happen and it is pretty awful when it does although rare. The Resolution of the Samsung headset is similar to the new Vive : 2880 X 1600 vs the resolution of my current set the HP WMR 2880X1400 or about .5 Megapixels more. So not sure if this would exacerbate the issue more.

    Note I have seen Vega 56's for $260AR recently but not sure it is even as fast as a 980ti, and the Radeon VII's are way out there price wise. Also curious if the AMD VR Liquid has anything substantial.

    Thanks in advance.

    If you can get a 1080ti for under $500 get one. Babeltech did tests on 5 games in VR and found that the 1080Ti is faster than the 2080 in VR.

    Who can say when the new tech in the Turing cards will be used in VR. I doubt it will affect any of the current headsets. Although the 980Ti and 1070 are both around the same performance, the 1070 will be faster in VR.

    What's your budget? If I was you, the minimum upgrade would be 2070 or 1080.

    2080Ti > 1080Ti > 2080 > 2070 > 1080 > 1070 > 980Ti

    Each successive generation does implement some features that are theoretically useful for VR, but the games have to support them, and not all of them do. As such, brute force fill rate is everything. The more the better.

    How much it matters depends on which games you play, but there are games where even a 2080 Ti is just barely enough to keep you out of repro most of the time with the latest HMDs, which have double the raw pixels of the OG Vive and Rift, and more like 3 or 4 times if you use a high level of supersampling (Which steamVR defaults to).

    Elite Dangerous is the poster child for this, but I notice repro in Robo Recall and Lone Echo on my Vive Pro with a 1080 Ti.

    Some games are fast at incorporating the new tech - for example Serious Sam had support for vrworks single pass stereo (nvidia pascal 1060+) and liquid vr (AMD Polaris/Vega) tech at launch, and I would be surprised if their next gen didn't also include support for some of the Turing specific VR works stuff like variable rate shading and multi view port. Some engines don't support any of those methods and they are fill rate bound, but for modern stuff the newer cards will be better long term as I think a large percentage now support single pass stereo, which doesn't work on 9xx nvidia cards. A year from now I'd expect a good amount to support SMP on turing and get a large performance jump over pascal, so if you're the type that keeps cards for 2 generations, I wouldn't go after a 1080ti unless it was significantly cheaper than an rtx card.

    SMP works with Pascal cards. The 1080ti is a much better purchase than the 2080/2070 for VR.

    Thanks for the info, I am thinking my budget is sub $500 so a used 1080ti is in there. It sounds like the new tech is not the greatest value proposition at this time.
