I know it’s been mentioned in other threads, but please be aware that many of these bugs are with the Oculus runtimes, and not the engine directly. We tested our internal benchmark demos, and saw the correlation of framerate was tied to the revisions of the SDK rather than revisions of the engine. In extended mode, there was no difference between engine and runtime versions.
In direct mode in some configs, if you can’t maintain the 75Hz needed to maintain, the framerate might drop to 37.5 (half the screen refresh rate). We’ve noticed that if your config has issues with Direct mode, Extended mode is often much better. As Oculus revises their runtime, should get much better!
