Mirror video/sound, performance questions


I can’t find how to solve some problems. Google also don’t help much. Please share you experiences with “Video mirror” and sound settings.

My problems are:

  1. Too much windows
    1.1) Game window always on my desktop screen. If i close window, game also closes. I think it eats my performance. I want to save my performance for the game. If i don’t record/watch with SteamVR i have 1 window on my desktop anyway (+1 window for each eye in HMD, 3 total).
    1.2) While i use SteamVR for mirror the video i have 2 widows with the game on my Desktop (game window + SteamVR window + 2 HMD eyes windows = 4 total).

  2. Mirror Oculus games (for example Lone Echo). When i want see gameplay on my Desktop i can see only 1 game window (with only 1 eye). Also sound plays only in my HMD, headphones and speakers are silent. I don’t know how to enable Video mirroring of Oculus games. This option is unavailable in Oculus software. It asks me to register my HMD, but it wants Oculus Rift/Quest and can’t register Pimax HMD.

  3. Run SteamVR games without steam - just don’t know how to do this. SteamVR always starts.

  4. Bad ingame rotation with Valve Controllers stick. When i rotate my head, virtual world is rotating smoothly. But when i rotate with stick on my Valve index controllers, virtual world is stuttering. It looks like low DPI on your mouse. (For example: instead of turning 75 times by 1 degree, it turns 25 times for 3 degree. It’s just an example, i didn’t measured any values).

  5. Half-Life Alyx, performance leaks. It looks like some errors are accumulating. When i die and load the game performance is going worse and worse, and after few times it become unplayable. Need to close game and SteamVR. If i close only the game, in HMD i still see Alyx loading screen, dissapear only after i close SteamVR too.

Please share your ideas.

Some games require being open on the desktop(well quite a few). It may use some performance but maybe not as much as you would think as the gpu intensive work is completed your just displaying a mirror. Similar to clone displays in a multi-monitor set up.

Oculus video mirroring not sure. For Audio you might be able to enable sound mirroring via sound control panel or may need a program not sure.

Running games without SteamVR depends on the game as some can run in Oculus mode. There was a workaround that worked for Project Cars 1&2 and Automobilista 2 however it seems to be broken.

Thank you. I’m enjoying my 8kx only 10 days and tested only few games.


Your quite welcome and congrats!
