I would at least give octane a chance before jumping to vray. Try to avoid very reflective surfaces, too many lights , optimize your settings and you will get reasonable render time.

Here you can see similar lighting scenario we rendered with octane https://vimeo.com/112264174

Thanks!

Not so much flicker but noise issues for sure. We made noisy previews till we got approval and then rendered final quality clip out in one week and even then did some light noise reduction. Fur was really basic and did not cause that much problems apart from slowing down compiling and rendering times. We baked max hair to polygon mesh with HairBaker script (http://www.scriptspot.com/3ds-max/scripts/hair-baker).

I tried with 50000 sampling rate on each light, and rendered it again. It helps abit but I can still see noises...
also max samples is on 3000 GI clamp 1.0 path term.power .01

I haven't tried caustics blur setting yet, I will try it today

what else I can do ?

Is this the https://www.redgiant.com/products/denoiser-ii-color/ plug you are referring to ?

Thanks
We only render using Direct Light AO. It has the cleanest image but unfortunately we are missing out on the color bleed like diffuse has, etc. Currently Direct Light Diffuse, PT are way too slow and too noisy for animations especially when you have lots of lights, dark scenes or scene takes place in the shade unless you can afford 30000 samples per frame. Maybe one day Octane can render as clean as CPU. But still with AO we get great results including motion blur, DOF etc and it takes 1 minute per frame at 1500 samples per frame. No other renderer can do this fast and easy to set up.
Also if you look at any movie up close you can see noise moving around especially night scenes may be it is the only way for now
