Oculus Rift with Unity crashing on play - unity3d

I have installed the Oculus SDK for Windows and the Oculus Run-time for Windows. I set stereoscopic and VR enabled to true in the player settings in Unity. I am running Windows 8 with:
Unity 5.1.2f1
Intel(R) HD Graphics 4000
NVIDIA GeForce GTX 660 M
When I hit play, the screen goes black, the laptop makes a screeching sound, and then I get a notification in the bottom right hand of my screen that says my Intel(R) HD card stopped working but has recovered.
Any suggestions?

Does the Oculus demo scene work? What version of the runtime do you have? If the demo scene doesn't work, it's probably the 2 graphics cards you have running. You're on a laptop right? Try turning the intel one off in the BIOS.

try Upgrading your Intel HD driver you can download it from here

unreal engine 4 : Macos version is very laggy

I use unreal 4. I don't know if this is the problem with macos version of something wrong with my specs. I use macbook pro 16, Intel i9 8core 2.3 ghz, RAM 16Gb, VGA AMD Radeon pro 5500M. It's laggy and slow. If i click a button seems that i can feel tiny bit of delay.
It took about 25sec to load empty vr project.
Everytime i start unreal, it always do 'compiling shaders..' which always make my whole system slow. is this normal? compiling will run everytime i start unreal engine and took more than 1 minutes to finish.
I only have 1 test project in unreal folder , it's just simply empty project.
Anyone mac users and have the same problem ?
Thanks

Why is my unity crashing while I am testing my game?

I am trying to make a game through Unity. I used to be with Unreal Engine but it did not really suit my pc so I got that instead. I have visited the Unity website and created a dump file for unity.exe but my project seems to crash all the time when I press play.
Is there any way someone can try to help me?
I have:
Intel(R) Core(TM) i7-4790 CPU # 3.60GHz
16GB RAM
Intel(R) HD Graphics 4600
99% chance your integrated GPU Intel(R) HD Graphics 4600 cannot handle Unity.
This used to happen often on my AMD Radeon R7-240, even though it is better than Intel(R) HD Graphics 4600.
See:
https://gpu.userbenchmark.com/Compare/Intel-HD-4600-Mobile-115-GHz-vs-AMD-R7-240/m7676vsm8608
If such is the case, I would recommend getting a dedicated GPU or downgrading to an older version of Unity.

Unreal Engine 4.20.1 VR Preview Greyed Out

As title says, the VR Preview option from the play menu is greyed out. I am using the Vive Pro and SteamVR.
Things I have checked:
Vive Pro devices' firmware are all updated.
I am using SteamVR beta and it is updated.
I made sure the Vive Pro were connected by testing them in SteamVR Home.
I have disabled SteamVR Home before launching Unreal Engine
I have tried both the UE4's VR template and a empty game (Blank template,
Mobile, Scalable, No Starter Content).
I have double checked that the SteamVR plugin is enabled.
SteamVR window says Ready and all 5 devices are green.
Computer Specs:
OS: Windows 10
CPU: Intel(R) Core(TM) i7-8700K CPU # 3.70GHz
RAM: 16GB
GPU: NVIDIA GeForce GTX 1080
Additional notes:
I have packaged the VR template and ran it. The headset does not rotate camera
but the controllers would still teleport me.
vr.bEnable Stereo 1 does not do anything, at least visibly.

I've been able to install genymotion on Windows 7 Ultimate.
I've done the below as well...

- UTC clock enabled.
-Turned up Video Memory to Max.
-Enabled 3D Rendering.
-Genymotion and VirtualBox both upgraded.
-Added Google Play
Running on intel sandy bridge.
With newer AMD graphics card.
But I'm still getting graphics like this in games.
Is there anything I can do to fix this?

mac osx webcam for avd of nexus 7

Below is a screenshot of my AVD. But right now it does not use the camera on my laptop. So I changed Front camera from Simulated to Webcam0; except, after that when I run an app the AVD Emulator does not show up at all. After I edit back to Emulated, the emulator shows up.
Is it possible to use my laptop's camera with the emulator? My computer is osx mountain lion.
