Apparently there is new option in steamvr beta 1.16.1 that allows you to lock fps and still using smart smoothing.
Do we have topic for this to discuss? I didn’t find anything about it here and it’s huge game changer!
Added per-app settings for overriding automatic throttling and prediction behavior. This is useful for applications with particularly poor performance that benefit instead from a fixed lower framerate for an overall smoother experience (e.g. sims). Note: These settings are only available to headsets which use SteamVR’s compositor (e.g. Index, Vive).
Allow motion smoothing to apply up to six frames of extrapolation (was three). Note: This also only applies to SteamVR’s compositor.
