    Recently bought Rift S and tinkering around to get the best performance in VR games. I've come to find out openvr seem to be 30 to 40% faster than OVR.
    So far I've tested Euro Truck Sim 2, Assetto Corsa, Assetto Corsa Competizione, Rfactor 2 and using steamvr instead of native oculus sdk seem to result in faster gameplay.
    I have oculus debug tool to show performance and overhead is anywhere from 30 to 40% more in openvr and better framerate.
    I have PD override at 0 with no ASW. I made sure to turn on performance mode in the HMD and turn off anti-aliasing.
    The overhead is 30 to 40% more in openvr in the same game. My CPU and GPU usage seem to be the same (over 90%) for both SDKs but I get way more FPS in openvr.
    What would be causing this discrepancy?
    My spec is below

    Gigabyte Z390 Gaming
    9900k OCed to 5.3 (Liquid Cooled)
    2080 TI FE OCed to 2100 (Liquid Cooled)
    16Gig 4000 DDR4

    PS. I've tested with default settings and it's the same.
