Unity Oculus SDK Update - Performance issues

Hello all, I'm having a performance problem that occured after the update to SDK 1.10.2. 

I'm having good FPS when the Oculus headset is not mounted, as soon as I mount the headset the FPS seems to be limited to 45 frames. In the profiler it is the VR.DeviceSDK process that takes the most time. See screenshots for before/after stats. 

Using Unity v5.4.2f2,Oculus Utlities v1.8.0, SDK 1.10.2. 

I've tried enabling the Graphics Jobs (Experimental), that did not change anything. Removing objects does not seem to change anything. 
Anyone know why this is happening?

    See this post. ASW is kicking in because the app is not consistently running at 90Hz on the CPU and GPU. From your profiler graphs, it looks like the bottleneck may be in pixel shading. Try enabling Unity's GPU profiler to see where the time is going.

    Thank you for your response, the GPU profiler helped us find the main issue's that caused it. I wasn't related to the new version or any update at all.
