Why is my fire simulation so blocky in Cycles rendered view? I'm making a candle, using a Mantaflow fire simulation, and all looks good in solid view. But when I switch over to Cycles rendered view, the flame looks very blocky and low resolution. It looks the same in the final render too. I followed tutorials using Quick Smoke to set up the flame, but for whatever reason mine always turns out looking way worse than theirs.
I've tried applying the scale of the Smoke Domain and Emitter objects, raising the resolution divisions on the domain from 64 to 128, and lowering the step rate of the domain material. None of these made any noticeable difference.
I'm quite stuck here, so any ideas would be much appreciated.
I've animated flames in blender a few times in the past, and one thing I learned is that if you want the flames to look realistic.  You usually have to set the resolution divisions REALLY high.  Around 600 or even 700 division should make it look really nice. Or maybe 400-500 if you're not going for super realistic.  Yes, it will drastically increase your rendering time, but that's the price you have to pay sometimes.
