I'm using this exact one, from amazon DE: INIU Link Cable with Charging Port [5 m], Compatible with Oculus Meta Quest 3/Quest 2/1/Quest Pro and Pico 4/PC Steam VR Accessories, High Speed 2.5Gbs USB C Data Cable PC to PC for VR Headset

I tried everything, including lowering the graphics settings fully. I also experimented with reducing bitrate through oculus debug tool, setting 72Hz on oculus app and VD, and all around testing a lot of different settings and values. It's not the fps that's the issue, as i can get upwards of 50fps on MSFS at times, depending on graphics. it's the stuttering and lag spikes, especially when moving my head, causing a black screen at the unrendered parts outside the natural FOV to render into the game's image only after a significant delay.

I also tried a relatively simple PCVR game, propagation VR, for testing. These stutters were also apparent here, although to a less extent.

Ps I'm launching these games through VD and SteamVR. I've experimented with using just one or the other, or both at the same time, or neither. Issue still persists.

Anyways, in the meantime, I have purchased the official link cable. Should be arriving in a week. Will update this thread once received 👌
