[Issue]: Poco x7 pro bad vsync

[Shiva95-GitHub]

Describe the bug

I have vsync issues with this smartphone. Streaming at 60 or 120 makes little difference. The same happens if I limit the app to 60 FPS. I experience heavy stuttering lasting about 5 seconds every 5-10 seconds (frame pacing set to maximum smoothness). If I use other settings, the situation worsens. No network frame skip

On the Huawei P20 Pro, however, with maximum smoothness, I only get a single microstutter every 10 seconds or so. There's no comparison.

On Steam Link and Parsec, I have no issues with the same codecs. (Steam Link seems great on this smartphone, but unfortunately, it causes stuttering in the host's frame time).

Tested on UFO Test

I have an Nvidia RTX 4070, Ryzen 7700, 32gb ramm

Poco X7 doesn't have the performance to decode in realtime properly. Try lowering the bitrate and lower resolution.

[Shiva95-GitHub]

Resolution and bitrate make no difference. Even at 720p, it's the same.

Again, on Parsec and Steam Link, even with AV1 NVENC, it's perfect! Even at 120 FPS.

[ClassicOldSong]

Can you check if Parsec and Steam Link is using the same decoder? Like if they're not using the realtime decoder, they can perform more smooth but with more latency.

[Shiva95-GitHub]

On Steam Link, the latency seems even lower or similar. How can i verify steam link decoder?

[ClassicOldSong]

Honestly IDK. But you can enable performance overlay on Artemis to see what decoder it's using right now.

[Shiva95-GitHub]

Mediatek low latency

[ClassicOldSong]

Eh mdeiatek.... Infamousely shitty on decoding and requires CPU boost to become smooth. Someone tried running a benchmark software in the background while streaming and it actually improved performance...

You can also try modify the package name to Antutu as mentioned here: #113

Phone manufacturers don't know what Artemis is and they won't enable high performance mode when running Artemis, you have to workaround this problem yourself unfortunately.

[Shiva95-GitHub]

Steam link say android hardware texture decoding on decoder with overlay.

Workaround not work for me

[ClassicOldSong]

I don't own MTK devices so I can't test, I'll try to add a toggle to select other decoders.

Also what does it show on https://www.testufo.com/refreshrate when you open it directly on your phone?

[Shiva95-GitHub]

60hz at 60hz display mode

[Shiva95-GitHub]

What could be the cause of the stutter on the host when I use Steam Link? Random stutters in the frame pacing. Without streaming frame pacing Is perfect

[ClassicOldSong]

IDK, maybe ther're trying to frame pacing the game for more smooth capturing(Apollo/Sunshine receives frames passively), but that restults in other problems.

If this is Poco, did You try to add moonlight to the game boost app (built in one, game center or something)? Then it will see it as a game with the possibility to keep it in higher performance mode.
