There are many features of OTT that won’t set unless you follow specific procedures and double check they are set. Many people will just use it and assume they are getting the benefit while in reality the setting is still at default. SS and FOV restrictions are two very finicky settings that can easily not be set even when shown to be set.
There are other settings that persist even between booting your computer. You might want to check your ODT settings for the link cable settings - bitrate etc. I would guess these will be set as per your last time using OTT - even if it was weeks ago.
While everyone is aware of ASW not everyone appreciates that it causes judder as you both go into ASW and come out of it. When you fly in high density areas your almost guaranteed to be in ASW all the time - hence it feels smooth to you.
Forcing the Oculus HMD to run 45hz with ASW disabled will guarantee that as you exit that high density area you won’t get judders as your frame rate jumps back up above 45hz.
Note 45hz simply means half frame rate, so if your using CV1, it’s 45, if your using Rift it’s 40 and if your using Quest 2 it’s half of what you set 36, 40 or 45 and the soon to be 60.
