Just replied to you in another thread but I spent the afternoon testing those settings in the forum link above.
I actually can’t get a good performance in MSFS at 960 mbps 90HZ. Lowering the encode bitrate to 400 improved my experience a lot, less latency, no audio cut outs.
Interestingly, dropping my refresh rate to 75 Hz from 90 Hz improved the colour banding compression as well and it looks and runs great. 75 Hz actually looks smoother than 90Hz, I believe because the cable and XR2 chip, at maximum resolution (I’m running 2896 x 2618 per eye) just can’t quite keep up.
I’ve got a 13900K, 4090 PC so it’s not my hardware specs.
