Unreal Engine 4.7 Preview

Any GearVR performance tips for preview build? I managed to get it to run FPS template from latest GitHub, shadows weren’t working on cubes as-of morning but from above I know it is in pipeline. I did manage to get it to hit 60FPS by changing skydome and using a simpler one as well as turning off AA, blur, lens flares, bloom, no mobile hdr, etc…

Performance even at 60FPS feels laggy though and evidence is that when you move your head quickly you feel like there is a reduced FOV due to timewarp kicking in and you seeing left edge that has been warped. Are there any guidelines? Is performance going to improve further in release and just being held back a bit or is what we see right now what we will get for 4.7 final? Also, any tips on how buttons and trackpad are mapped in unreal for use in blueprints?

Thanks!
