OCULUS Rift DK2 arrived :-)

After unpacking the new DK like a child in front of the Xmas Tree, I installed the Rift like it was described in the manual.

The installation process in Windows 7 went nice and smooth, and I was impressed by the higher resolution and the great motion tracking with the IR sensor, while visiting the demo room, which let me forget the pixels which where much more present in the DK1.

The next thing to try was – of course – the new Oculus World Demo. Again I was surprised by the quality comparing to the DK1. Also the Direct HMD access is a nice feature.

Nevertheless I had some trouble getting the displays to work. For me it’s still not clear why I use the extended desktop mode, but it works for now – still there are some things to tweak, but that’s ok, in a development stage.

I had some issues getting good fps, I’m owner of 60Hz flat screens, bringing down the Oculus also to 60Hz isn’t the best solution. Leaving the Oculus Display at 75Hz and trying the Oculus World Demo gave me in the end the possibility to reach the 75 fps. I didn’t recognize, that a actual gaming graphics card is a minimum requirement, so I was a little disappointed by the juddering and low frame rate at the World Demo. But I didn’t gave up – buying a new graphics card – a read a lot about this topic, and tried a few things to bring up the frame rate. First thing was to use the extended desktop, after that I had to be sure to be in hardware full screen mode by pressing <ALT>+<Enter>, finally I turned off the multisampling with F4, and now – a nice fluent image with no juddering. I also tried some other things, in my case Aero can stay on, the Oculus HMD can be the secondary screen and if you are in hardware full screen mode, you don’t have to care about overlapping windows, etc.

So having a GT 630 for the rift isn’t that bad, as I thought in the beginning, of course I have to reduce the quality to avoid becoming sick of the latency, so I just have to turn off some AA and reduce the resolution in some cases. (which is unfortunately not possible in some early demos)

I also tried OceanRift for DK2 which is a very nice work for the Oculus, and know even better through DK2.

I also had to spend some time watching UE4 DK2 Demos, because I wanted to use the engine for my own projects.

One Demo is UE4Rollercoaster V0.3 which made me sick, not because I had to find out, why it doesn’t work – thanks to the guy who wrote a program to turn the Oculus services on and off :: Oculus Runtime Utility by Bilago, because for know they have to be turned off while running UE4 Demos – the Demo had such a bad frame rate, putting the quality down to nothing just showed me a mass of pixel, of course the main reason is my graphics card. So I had to find ways to bring up the frame rate in my own demos.

I made a small Demo named “Tribute to Tesla” with UE4 which can be downloaded from the projects page, you can change the quality setting by pressing <l> for low, <m> and <h>, so there shouldn’t be any frame rate issues, also UE4 offers a lot of post processing effects, which I had to use 🙂
