Oculus Rift DoF problem
While DoF is on, together with motion blur, on the right eye/screen i have this error. It depends on the ambient quality, if the ambient quality is flat, the problem is allmost gone, but still there.. This is how it behaves.

[Image: 2dlo1p]

DOF on high, MB on- you get that distortion on the picture

DOF on Enabled, MB on- there is no distortion

DOF on enabled+Use Half render targets, MB on- shadow flickering, and DOF reinitialisation/recalculation on every 60 frames i think..

DOF on High+Use Half render targets, MB on, you get the distirtion as on picture + shadow flickering, and DOF recalculation on every 60

This world shows that more than others, but i get the flickering on other worlds, really annoying and makes you dizzy .. Also, there is no difference to what you set the motion blur to, it allways behaves the same, so i guess the DoF shader creates the problem.

I can't see your image.

I have used dof and motion blur at the same time and they didn't cause any issues for me.

Hi,

I've tried a few combinations of the settings, but didn't have a similar problem.

Could you attach a small sample 2.0 project with the error visible?
Then I could investigate it.

Thank you

Yes but I need a sample project to reproduce the issue, this can be either 1.0/2.0, but 2.0 is preferred because it's simpler.

Hi,

To shortly introduce myself as a newly active member on the forums, I'm a member of 3Dea team.

The problem is easily reproducible by setting the value of dofMode to DOF_HIGH with value of motionMode set to either MOTION_LOW or MOTION_HIGH - in these cases there is visible flicker on the right eye picture when stereoscopy is enabled. If any of these parameters is set to _NONE, the problem disappears.

I've attached the modified "Rift tutorial.cpp" which exhibits the described behavior when these settings are changed, exactly the same as in our app.

Hi,
I've just tested this and I have no issues.
Perhaps this is a big in your graphics card driver.

Hi,

We've done some testing and can confirm this issue is not related to specific GPU or driver version, yet it does only occur in DX10 builds - DX9 build works as expected.

I've attached an additionally modified version of "Rift tutorial.cpp" which includes the example with ambientMode setting - when set to anything apart from FLAT, the same issue is visible as described before for the combination of dofMode and motionMode settings (DX10+).

Hi,
Yes I was just testing it again, and too discovered that the issue occurs only in DX10.
Thanks, I'll try to fix it (and check your new file too)

RE: Oculus Rift DoF problem
Hi,

I've did some debugging and I'm confirming that this is a bug in graphics driver affecting probably all of Nvidia under DX10+.

When I run the app with DX10+ on my laptop, then when using Intel HD 4000 I have no flickering, but when I use GeForce 650 GT I have flickering.

Hi,

Thanks for your effort, we can also confirm that this issue does not occur on an AMD HD 7800 card, so it must be nVidia specific - we tried several different GPUs and driver versions.

Searching on the web we could not find any reports on people having same kinds of issues with nVidia / OR. When and how do you think this can be resolved or get around? Finding a way of supporting stereoscopy on nVidia fully would be of great importance since it makes for a large share of OR adopters community.

I think the best way is try contacting Nvidia and letting them know about their driver issue.
