I’m having the same problem, but I disabled Interleaved re projection in SteamVR but it did not improve my fps issues. I’m running the latest SteamVR version and tried the Beta release as well and no luck. I know this isn’t really the place but I really would like to see the ability to grab 4.14 since I’m stuck with 14.1 and there’s nothing I seem to be able to do about it.
