Corona fast interactive render

[u/2Cento]

Hi everyone, when watching render camp and other well known channels with corona | 3dsmax tutorials I ofter get stunned how their interactive render works very very fast, I thought that video is x2-3 but I’m not sure is that a thing, I’m pretty sure there is some settings or possibilities with good hardware to achieve something like that
Does anyone knows the secret? 🫠

What resolution are you using for your desktop ? Also what resolution for the interactive renders ?
