I have both the index and now the rift S. When I try the rift s in both oculus mode and steamvr mode the performance is very bad. I have tried disabling ASW via the debug tool, turning off async render, turning back on. On the index though everything is buttery smooth at 120fps. I am not sure if you have a rift s to test ralf but it’s not running very well.
With the index though it’s very good albeit I still have the weird bug where I can to turn vorpx’s async render ON then back OFF again to get the native 120fps, or else it caps at like 60.
