AMD 9070XT VR good idea?

Are the 9070's better do you know? For h264?

Here is a quote from the technical deep dive on improvements AMD made for RDNA4.

Navi 48 comes a dual media engine, each of the two can perform concurrent encoding and decoding, and so the implementation resembles an NVIDIA GPU having two each of NVENC and NVDEC units. The new generation media engine offers a 25% increase in H.264 low-latency encode quality, and an 11% improvement in HEVC encode quality. AV1 encode and decode gets B-frames support, vastly improving bitrates. A B-frame is a frame that lacks image information, but instead motion-vector values, that lets the decoder reconstruct the image component using past and future I-Frames (frames with image data). The media engine posts a 50% generational performance uplift (measured in encoder/decoder frame rates), with reductions in memory overhead.

This seems to be confirmed in reviews.

 
And after saying I was going to skip this generation, I found a 9070Xt and only slightly above MSRP, so bought it.

Will let you guys know what its like for VR as soon as I get it. No idea of delivery time or date yet. Hopefully it will be before next Friday. Paddy's day is going to slow things down of course.

you never answered my question. Or maybe you didn't see it. But, what did you mean by broken HEVC??

Some models in the 7000 series had a hardware HEVC issue at certain resolutions—though I’m not sure exactly which ones. It’s been resolved with the 9000 series.

I didn't see it. It's something I thought someone said in this thread. It may have been another similar one. I have no experience of it, so am trying to find out and avoid an expensive mistake buying something that doesn't work properly. It seems I was mistaken, or the person I quoted was. Watching the video you posted didn't seem to illustrate anything terrible that needed highlighting. I look forward to your results with your 9070xt and Q3 is it?

For VR headsets that require streaming, like the Quest 2/3 and Pico 4, there is no issue with HEVC when using cards from either AMD or Nvidia. It's only when you use the H.264 codec that there is a difference. Maybe the results weren't clear from the Video that I linked to. But in practice the difference can be massive. Like when I switched from the 2070 super to the 6900XT, I honestly thought my 6900 was broken. I was getting more performance in VR games but everything looked far better on the 2070 Super. I can't speak for the RDNA 3 cards because I never tried one myself, but it seems hit and miss from reading the various forums.

I am looking forward to the 9070XT too. I really wanted to go Nvidia but if the codecs have been improved, then the 9070 should be just fine. And yes, it's a Quest 3.

Spending all this money for VR, hope its worth it!! :p

I look forward to your updates...It's payday next week so i'll be looking out for GFX card deals, and maybe for 2nd hand Q3s too
