NOT Solved. Pixelated DOF issue on out of focus objects close to the camera when rendering through Movie Render Queue. (UE 5.6)

For some reason the topic below is listed as solved when it has not been solved. My response below.

This topis is not solved. I’m running the latest version of Unreal Engine 5.6.1 and it is still happening. This issue started happening just after updating to the latest version of the NVIDIA Game Ready Driver. I rolled back to version 577 and it stopped happening so it is confirmed the issue.

Reverting back to 577 cannot be considered solving the issue. People still need to at some point update to the latest version and we can’t control what version of the Nvidia drivers are installed on our players computers. This completely renders depth of field unusable as the amount of pixelation varies depending on the window size. The images below are best case scenario in some instances it looks like a transition screen for the 8-bit nintendo…

So far I have tried these steps and non helped:

  • Increased DOF quality through: r.DepthOfFieldQuality = 4

  • I tried to increase other DOF related console variables and non worked

  • Increased AA Temporal samples and spatial samples

  • Tried other AA methods - TAA and TSR

I have to say that the issue is not visible in viewport and only when rendered using MRQ.

Appreciate the help if any1 has a clue!

Seems highly likely due to downsampling somewhere in the DoF settings. You might try experimenting with the relevant cvars. For example r.DOF.Gather.ResolutionDivisor is set to 2 by default (half res). Try setting that to 1.

i am not sure if this helps, but keep in mind that DOF stage runs very early and it’s prone to run at lower resolutions.

pd: your post doesn’t look solved here.

I’ve tried all of that and none of it works. The only thing that worked was rolling back the NVIDIA Driver which as a pain to do. This is either an Unreal Engine or NVIDIA driver bug that they REALLY need to get fixed asap. This makes DOF look ABSOLUTELY HORRIBLE.

Jumping in on this.

Having the same problem on a RTX PRO 6000 with today’s drivers from NVIDIA (581.80-quadro-rtx-desktop-notebook-win10-win11-64bit-international-dch-whql).

In my case this happens in the viewport as well.

No console variable seems do do much. I noticed that the effect gets amplified when Alpha is enabled in Project Settings.
