ALVR Settings with Quest 3

I have been using ALVR using a wired connection to my Quest 3 to access SteamVR. I wonder if anyone else was doing the same and what settings you found to be the best?

I was most curious about these two settings:

Bitrate: Default is 30Mbps but I have experimented as high as 70.

Preferred code: Default is h264 which I find terrible. I have better performance with HEVC.  However, I read that AV1 is built into the NVIDIA drivers, but I have better frame rates with HEVC than AV1.

Any other settings that would improve performance?


I have been playing:

Half-Life Alyx

Black Mesa VR (excellent!)

Half-Life 2 VR 

Skyrim VR (with mods)

Aircar


Before the Quest 3 I had the Samsung O+ and the Valve Index. So far, I've been happy with the Q3 though I have some complaints:

-I miss the OLED screens from the O+ and Index. I didn't think I would, but Skyrim VR is better with OLED given the darker places to explore. Not a deal breaker or anything.

-I wish Steam wasn't so clunky to get to work on the Quest line. Given the huge market Steam has, they should have done a deal with them to make Steam just work on the Quest line.

-I was shocked that Meta didn't have a port of Minecraft for the Quest line. That seems like the perfect game for the Quest line. The bedrock port for Windows runs amazing well even on low specs. I have tried Questcraft but it gets stuck while downloading the game. 


Thanks!

    Bro, if you're wired, use max bitrate. If you're using such low bitrate, than h264 will be bad because of it.

    I use these settings. It works for me. I may try the medium preset once I get my RX 6800 graphics card. Right now I'm using a Quest 3 headset, an RTX 3060 GPU, Ryzen 7 5800XT CPU, and 64 gb ddr4 ram 3866 speed. I use the 1.5 upscaling, so I definitely could use the medium preset right now to get it to look better, but I like my current GPU overhead.
