Hey I just reported this, a major performance regression to all SteamVR games:

Major SteamVR performance regression (hidden area mesh not being generated) - XR Development - Epic Developer Community Forums

It affects all engine versions because it was a hardcoded assumption changing, but it would be really nice to get it fixed for 4.17! The OpenVR version the engine uses already has a way to directly get the visible area mesh, so it is an easy fix.

Nice catch, seems quite serious to me!
