Hi all. I've tried everything I can think of, but can't seem to get rid of the noise in the reflections of my windows. I'm using a glass material from the Octane Live DB and have my max samples cranked up to 2048. In other scenes I've created, window reflection noise has never been an issue. The problem is that this is a 300 frame animation and at the current render settings, I'm looking at 6+ minutes per frame to render...going any higher on the max samples would make the render time inefficient. In other scenes without windows, I've been able to render at 1024 or 1536 max samples in about 2 minutes per frame. I'm hoping there is another setting I can tweak that will reduce the noise (besides de-noising the entire scene in AE). Thanks in advance for any tips.

try fake shadows.

I'm half way tempted to just get rid of the glass part of the windows and just keep the frames. The windows aren't the focal part of the scene, and noise would make them so.

Try to reduce reflection to "0" on window material. it will look ugly but can solve your problem

Thanks for the tip. I tried it, and I might as well get rid of the glass altogether if I'm going to reduce the reflection to "0". I tried different variations of reflection strength, but still have noise. I'm hoping I can keep some reflection to make the scene more realistic looking, but I'm thinking it may not be possible and still attain reasonable render times. If this was a single frame, I'd max out everything, but with 300 frames to render, that's just not realistic.

dont use specular. make a glossymat with index 1 and use a falloff in opacity.

No need to spreading this. Just spend some effort on scene. Devil is in the details.

Here is a quick try.
