Chromatic Aberration Issues

[thekiwimaddog]

Hi everyone! I've received my DK2 today and have been playing around in both the Oculus World Demo and the Demo Scene and I'm noticing a large amount of chromatic aberration towards the edges of the screen. I've been playing around with the settings (IPD, Eye relief, Eye Cups) and nothing seems to help with this issue. In fact I can't even see a noticeable change in the chromatic aberration correction when viewing it using the monitor for reference and picking what I think are extreme values. They all just seem to produce the same correction effect.

Should the IPD, Eye Relief and Cup type change the chromatic aberration correction effect? If so can someone tell me the extreme values that I can choose for a comparison as I'm wondering if this is just a bug and my settings are not being applied to the distortion correctly.

Does anyone else see this chromatic aberration?

Thanks Everyone!
David

The question is whether chroma-separation is a better tool for measuring eye-relief than the line-tool. It's a good question. 😉

I probably would argue in favor of a more real-world oriented calibration approach. The problem with the line tool is that the objective itself is somewhat vague. I don't remember the exact wording, but I think it was something like "the line should be barely visible". Every time I guided someone through the calibration they asked: What exactly is "barely" visible? Does the line actually have a width of 1 pixel? To me it always occurred as if it has a width of several pixels and there was always a very broad range where "barely visible" applies (from a "peripheral glow" to "width fully visible"). If the line tool has to stay for IPD / fovPort measurement I would highly recommend to at least give a more precise specification of the actual objective. Another problem is that the measurement will often be biased, since the setting of a vision test may lead to squinting one's eyes or a non-neutral facial expression in general. Maybe a lot of these things can be avoided if it is possible to perform a calibration intuitively with a basic test scene and the objective to "just make it look right".

So...my separation issue is a lot worse than a line of pixels which makes me think it's something I've probably failed to set properly.

The colors, whether on screen or DK2 are not even attempting to line up properly. I have witnessed in a statue game that as I walk around the green and red representations of the same object sometimes get closer together and eventually I can sometimes get them to merge into a solid object.

This doesn't seem to happen on tech demos that don't have a starting configuration prompt, like Rift's Cave and Titans of Space, with the exception of "Tuscany_FMOD_AstoundSound", which does not have the config prompt but does have the issue.

However, the bulk of the other demos I've tried, including the Hydra, all have the same result. If they first kick up the config prompt as seen here:
https://www.dropbox.com/s/hxpi258des9toxd/01_config%20prompt.png?dl=0 then it looks like it doesn't matter what I pick in the settings, I get an outcome that has the colors so off that it's not usable.
Here's the resulting tech demo from that prompt: https://www.dropbox.com/s/tywd4ez982bev4i/02_split%20colors.png?dl=0

from other demos:

This happens whether I run it in window mode or not, regardless of res setting or graphics level.
I'm in windows 8 with a DK2 running yesterdays runtime release. I have updated the driver.

Any help would be appreciated.
Thanks

Those certainly look some sort of bug as opposed to chroma settings. Chroma should have little separation in the center with gradually increasing separation at the edges.

Any ideas on what I could do? It started from the get-go with the previous runtime, and has continued with the runtime from this week. Obviously I've rebooted more than once during the time. I haven't tweaked any of the nvidea settings at this point.

My specs are
GeForce GTX 750
Intel Core i7-4790S CPU @ 3.20GHz
12 GB Ram
current res on main: 1920 x 1080 and it's a touchscreen
nvidea driver version 340.52
OS is Win 8.1

I think I have an idea what your issue is: you've somehow enabled stereoscopic display for all supported screens.

Right-click on your desktop, select Screen resolution and uncheck Enable Stereoscopic 3D settings for all supported displays.

In the event it is already unchecked, try to verify that you don't have anything similarly enabled via the NVIDIA Control Panel.

I say this because I had enabled the very same thing, giving me a real pain-in-the-ass experience with Half-Life 2, due to it suddenly feeling like I was in a bad 3D movie.

0.4.2 much less CA then previous build. Fine tuning with the eye relief setting (software) made it even better.
Big improvement.

That was it! Thanks. Now I just have the weird lines like everyone else plus a lot of the demos that use the config don't seem to use the head-tracking (as the gaze is fixed). Off to figure out that issue now that this one's resolved. Thanks again!

The CA is just as bad for me in Elite: Dangerous as it was prior to 4.2, even after recalibrating the config utility. I'm still even having pretty bad issues with it in the desk demo. Pretty much only the area in the center has proper color. Anything white separates at the edges into noticeable blue, red, and green bands. In the desk demo if I'm looking at the menu, the papers on the desk have rainbows for edges. If I look down then they go back to looking normal.

Is this similar to other people's experiences, even with the latest runtime?

You mean the update to the Oculus runtime you have to kill before launching Elite Dangerous didn't improve things? How could that be? 😉

ED is based off an older SDK.

Games have to be specifically rebuilt with 0.4.2 before they will see any chroma enhancements. The runtime alone will not do it.
