Vray 5 is slow than Vray Next?

[Karonte]

Hello and HNY 2021!
I have recently been using Vray 5 hotfix 2 in 3dsMAX 2020, and it struck me that it is noticeably slower than V ray Next. Old scenes rendered with Vray Next are noticeably slower with Vray5.

I love Vray. I used it since its beginning and always I updated my 4 licenses. Version 5 is very mature and intuitive....BUT..
I agree it is "slower" and for me, having sometimes to open old projects or import some old stuff is not good. I always have to find "why" is slower, where is the error, etc...too much human time lost. It's starting to be "slow" as Corona . I mean fast setup, slow rendertime.

Vray 3 was faster and cleaner. I believe that it's hard to speed up a render engine but I cannot understand why every new release is slower ( and sometimes very slow). I agree with tech data...but I believe in what I see and what I test on my pc.
Ah..another important question... If you changed the "render engines parameter" please create a new and comprehensible tutorial on how to set up this new parameter in comparison with the old.
Vray is also a technical engine so I would like more tech updated tutorials instead of putting the sun/sky and look how beautiful is the new model.

it is much slower....BUT thats due being able to get away with a higher noise threshold, i see people still using 0.005 and complaining when - scene dependent - they could use 0.03

People from the Chaus group I
usually don't post anything here but I'm been using Vray for 10 years and the majority of my material liberties and model library are from previous versions especially Evermotion I do not change vray to another render engine because of is flexibility and speed in good quality render however recently on this new vary 5 version I m not being able to use all my model, and my material liberty anymore because vary 5 is taking too long to load the texture paths in the 3dsmax 2021 and to update the geometry in big scenes this is becoming impossible to use the interactive render in big scenes I am coming back to vary next because even with all the new good improvements in the 5th version the basic activities the is to render interactive became impossible to work
