So as of today HEVC encoder in AMD cards works badly with square resolutions that are present in PICO 4. When using latest beta drivers HEVC encoding finally works with Virtual Desktop on PICO 4 but has stretching on right eye, cause as I've been told by VD devs is caused by AMD HEVC handling of square resolutions. I hope this problem will be fixed in future drivers or someone will tell about the way to fix this problem.
Thanks in advance. (That problem appears on screenshots of right eye too, left eye is fine)
Had you tried Borderless region capture?
Also had you tried to use OBS as proxy for AMF encoding?
No it's not about recording. It's about streaming image from PC to standalone helmet PICO 4. When i play in my VR headset i have those lines all the time during gameplay.
Using any kind of proxy for encoding will ruin the image and introduce delay that will make me motion sick
By proxy i meant other application that can make calls to AMF engine.
Because AMF is just framework... engine. And it is not exclusive to use in Adrenalin software.
Like, i do use 50 Mbps bitrate in Adrenalin. But if i wanna get minimal quality reduction, i will use OBS with CQP (constant quality) preset. It will allow for dynamic bitrate with all maximum values it will ever need (for my 1920*1080@60 on demanding scenes (and i have a lot of these), bitrate can go up to 200-250 Mbps. But with low dynamics bitrate will also go down to, like 400 kbps or 1 mbps.
This is still not loseless, but recording is all about higher quality = more bitrare.
P.S. Ah, sorry, is PICO is VR device? Then OBS won't work, i think. It is for other use cases.
But maybe there are still "proxies" that you may use?
Still, try to write in email tech support for this, maybe it will help you to get AMD in touch with issue.
Yeah it is a VR device and as you can see screenshot is from HL:Alyx. I've learned the problem is with sliced HEVC encoding that VD uses. Which email i should mail to ?
Here too with that problem. I have an RX 6800 XT running adrenaline 22.11.2 and trying VD and Pico 4 with HEVC gives that distortion to the right of the image. This only happens within games, it only happens when switching to SteamVR mode. Any solutions?
Try asking AMD email support for this.
Also... better wait few days for newer driver, check again and then report.
There should be new driver release for RX 7000 series
I got the same problem on Pico 4 and Virtual Desktop, deformation on the right eye.
H.264 can´t be a solution because the image compression are horrible and the image suck...
Ryzen 7 5800x3D
Any solution or can we wait for any path from AMD?
Thanks a lot
Download version of VD pre-november of this year and disable sliced encoding. From now on sliced encoding can't be turned off, as the developers said their further optimizations are impossible without it.
I have opened a technical support tiket to provide me with a solution. I was not surprised that they were clueless. They told me that they were not aware of the problem (lie), to provide links to comments from users who had the same problem. I provided this forum as proof but it seems that they do not care. Their technique for dealing with this is to act as if nothing is wrong, in an attempt to make the user think that it is a problem only theirs or that it is not important enough for AMD to lift a finger. Well, I have it easy. As soon as I buy the new card, which will be at the latest in January, if there is no solution to this problem, I go to Nvidia.
I spend more than 2K€ in a AMD PC and have not solution for our problems...
Next time I can buy NVIDIA + INTEL...
I have same problem. Please fix amd.
Also the same problem. Please Fix
When I bought my RX 6800 XT, I did it with the intention of testing AMD, as I had always had NVIDIA graphics cards. Big mistake. I have finally returned my RX 6800 XT and bought a 4080 from NVIDIA. The customer service from AMD is disappointing, at best. They treat us as if they don't know what they're talking about when we ask for solutions, clearly trying to prolong the situation, as if it would solve itself; asking for data that is not necessary for the solution and ignoring information that is provided, in other words, they don't care about wasting our time with their problems and then wasting it again with their lack of interest in solving them. The biggest mistake a brand can make is to place the burden of its product problems on the customer, and AMD does it without any consideration. I am not willing to pay 900€ for hardware that works defectively because the company that manufactures it doesn't want or can't maintain it. I think my decision is the best I have made in relation to this matter. I no longer have problems with Pico4 or other issues that I did have with AMD.
1 month late... thinking about sell my rx 6900xt and dont buy no more a High end AMD GPU...
It is horrific that not even a single post is in here from AMD to accept this problem. We should all report the bug via the Driver Software
Same here, 6800xt same problem on the right eye on Pico 4 only while using hvec. It's too distracting to play like this
Same here: 6900xt with 23.2.2-Driver
Also still the same Problem with 23.2.2
Is there any information if AMD plans to fix this?
