DLSS issue with volumetric clouds in Unreal Engine 5.1

Hi,

I’m currently testing the latest DLSS plugin for Unreal Engine 5.1 to speed up rendering clouds and noticed a fair amount of jittering when clouds are moving and DLSS is enabled. This is mostly visible in DLSS Performance mode with screen percentage at 50%, but is also noticeable with higher screen percentages.

Strangely, this jitter only happens when both DLSS and the volumetric render target are enabled. Disabling it (by setting r.VolumetricRenderTarget to 0) removes the jitter, but is not a viable option as it lowers the framerate too much.

Is this is a known issue with DLSS? Are there are any settings I could try to mitigate the jitter?

Thanks,

Samuel
