Agreed at 45fps lock for VR headsets. My Oculus always starts default with TIMEWARP enabled, and I have to turn it off (pressing shortcut key CTRL-NUMPAD1 a couple times NOTE: CTRL_NUMPAD4 turns it back on). The advantage of using 45FPS for VR headsets, is they operate in their own FPS space… meaning, your SIM will be running at 45, but the headsets will still be at 72/90/etc. This allows your System to feed the VR headset all the Head-Movement frames while the Simulator ‘casually’ produces the necessary scene. Point being, don’t let the SIM be the Bottleneck to your headset.
