With UE 4.5.1 (from launcher) and Oculus Runtime 0.4.3 I am suddenly capped at 37.5 fps (looking at a wall in Mobile Temple with screen percentage of 100 and reduced quality settings).

Looks like there has something gone horribly wrong :(

Profiler:

The strange thing: Neither CPU or GPU seem to be under heavy load:

With 4.5.0 and Oculus Runtime 0.4.2 I got stable 75 fps with everything else at the same settings at every place in the level. If I run a packaged version from UE 4.4 it still delivers the same performance even with Runtime 0.4.3 as before (stable 75 fps).

So who is to blame here? UE 4.5.1 or Oculus SDK 0.4.3?
