Performance Improvements ETA?

You mean you get 185FPS in Unity 5 without "Virtual Reality Supported" enabled and then you get 65FPS when you turn it on? ... To compare performance between Unity 4 and 5, please use U4 integration 0.6.1 and U5 utilities 0.1.0, which both work properly with the 0.7 runtime. You can use our performance HUD as documented here: https://developer.oculus.com/documentation/pcsdk/latest/concepts/dg-hud/. It will tell you how long Unity is taking to render as well as other important metrics.

Thanks for the response.

"Virtual Reality Supported" is always checked. With the Rift turned-off, I get 185+ FPS in my scene. Turning it on causes framerates to drop tremendously to a third of what they were before: ~65 FPS. No anti-aliasing, and I'm using a 1080p monitor and GTX 970. I currently will need to achieve 200+ FPS with the Rift off to ensure that when I turn it on I'm at a stable 75 FPS. There's always been a framerate drop in Unity using a Rift (half?), for many reasons, but it seems much worse now using Native VR mode. (I know this, because I've been doing a lot of optimizations during the past 6 weeks, and almost all of my gains in stability vanished with the move away from Plugins to Native. It's as if Timewarp is suddenly unavailable or something worse is going on.) I haven't used Unity 4 in months; my observations are purely based on changes seen since switching Native VR in Unity 5.1 with 0.7.

I'm not currently using the 0.1.0 utilities because I don't need them. Could that cause the problem? Is there a performance benefit to using them beyond what plain-old Unity 5.1.3p2 gives you?

I'll try to find time to integrate them and provide further metrics as time allows.
