Rift Display Mode - Direct HMD crashes

Javieret
Honored Guest
Hi guys,

I'm developing some experiences with Oculus Rift and I can run without problems in "Extend to desktop to the HMD" mode, but, when I try to use "Direct HMD access from apps" mode I get an error in all the apps that I've developed (even Oculus Desktop demo).

In my computer I get this error, but my workmate, with other computer configuration can run the same application (the same compilation, the same .exe) without errors in "Direct HMD access from apps" mode.

So, I think that the error is caused for the graphic card or some configuration about it.

I write here both computer configurations, and paste here the error that I get.

Please, does someone have the same problem? Does someone have some solution?
One is a laptop with two graphic cards. The other is a desktop computer that only have one. Could be the problem?


My computer configuration (is a laptop) (This computer get error in "Direct HMD access from apps" mode):
• Windows 8 Pro
• Oculus runtime installed: 0.4.3
• Intel® Core i7-4700HQ (2.4 GHz, 6 MB)
• RAM: 8GB DDR3 SODIMM
• Graphic or video card:
o Intel® HD Graphics 4600 (Integrated)
o NVIDIA® GeForce® GTX850M con 4GB GDDR3


My workmate configuration (is a desktop) (This computer runs fine, DOESN'T get error in "Direct HMD access from apps" mode):
• Windows 8 Pro
• Oculus runtime installed: 0.4.3
• Intel® Core i7-4700HQ (3.5 GHz)
• RAM: 8GB DDR3
• Graphic or video card:
o NVIDIA® GeForce® GTX750M con 4GB GDDR5



The error that I get in Unity app, bu i get the same in Oculus Rift Desktop demo that comes with runtime.

error.log:

Hey, I would like to know where did you get running log from the demo,thanks.

It's probably an issue with the dual GPU (Nvidia Optimus) as that is known to cause problems.

Unfortunately, I'm not sure there is a simple solution on your end to fix the issue.

We are aware of the problem, and will see if there is any solution. Thanks.

This needs to be made a priority; if the "Direct" mode is the recommended way to go for people using Oculus Rifts and yet to this day folks can't get this mode to work consistently across platforms then it becomes extremely difficult to develop experiences for the Oculus Rift.

Senior Oculus engineers need to be on this; and not just the one-off guy in the back of the office.

I've had the DK2 for a month. Direct HMD Access has never worked even once. Everything crashes, even Oculus demos. The exception is thrown in the Oculus driver.

I've been using extended mode. This works, but it says right in the display mode dialog that Direct HMD mode "reduces latency". Naturally I'd prefer that.

I'd like to chime in and also mention that I have the exact same problem that the OP has (except with Unreal Engine 4)

Direct to HMD crashes on my laptop but works in extended:

• Windows 8.1
• Oculus runtime installed: 0.4.3
• Intel® Core i7-4710HQ
• RAM: 8GB DDR3L
• Graphic or video card:
o Intel® HD Graphics 4600 (Integrated)
o NVIDIA® GeForce® GTX860M

Direct to HMD works fine on my desktop:

• Windows 7
• Oculus runtime installed: 0.4.3
• Intel® Core i7-2600
• RAM: 32GB DDR3
• Graphic or video card:
o NVIDIA® GeForce® GTX980

Had the same issue with some of the apps i had, ended up fixing it, by using the windows update and selecting and installing all the optional updates available then after a reboot they worked nicely.
just something to try if your still having these issues.

I'm having the exact same issues on all laptops as well. Any Oculus demo - including the one "built in" to the config tool - crashes. The error report is mostly gibberish to me, but I get this at the top:

Exception instruction address: 0x6cb1ab94 (see callstack below)
Exception description: ACCESS_VIOLATION writing address 0x00000000
Exception location: NVAPI_Thunk (444084)

I have disabled the onboard graphics through the BIOS, but the HMD still has an orange light on it. Only when I enter extended mode does the HMD light turn blue.

Not sure what to make of it. I guess a desktop computer with a standard NVidia / AMD gaming graphics card is practically required at this stage.

Have the same issue on a desktop PC:
• Windows 7
• Oculus runtime installed: 0.4.4
• Intel(R) Xeon(R) CPU E3-1245 v3 @ 3.40GHz
• Graphic or video card: NVIDIA Quadro K600

Running in extended mode is fine. But running in direct mode crashes. On the error report I have this on top:

nvd3dumx.dll caused an Access Violation (0xc0000005)
in module nvd3dumx.dll at 0033:dc223aef.

Hola a todos.

Tenia el mismo problema y he encontrado la solución (Al menos para mi caso).

1. Dirigirse a **C:\Program Files\Epic Games\4.7\Engine\Binaries\Win64** y establecer **compatibilidad para Windows 7** en el ejecutable **UE4Editor.exe**
2. Asegurarse de que **UE4Editor.exe** se ejecuta con el **procesador de alto rendimiento (Control de panel NVIDIA)**.

ESO ES TODO¡¡¡ Después de hacer mil pruebas y leer mil foros es lo que ha funcionado¡¡¡¡

Hello everyone. (Sorry for my english, i´m spanish).

I had the same problem and the solution I found (at least for me).

  1. Approach ** C: \ Program Files \ Epic Games \ 4.7 \ Engine \ Binaries \ Win64 ** and establish **compatible with Windows 7** in the executable **UE4Editor.exe**

  2. Ensure that **UE4Editor.exe** running with **high performance processor (NVIDIA Control panel)**.

THAT'S ALL¡¡¡ After making thousand tests and read thousand forums only that is worked¡¡¡
