I've just upgraded to Vue 9 Esprit 64bit from Vue 6 32 bit. Tried loading an old Vue 6 scene and it seems to slow everything down, from moving around the scene to selecting an object.
Also the 'Global Radiosity' atmosphere used in Vue 6 doesn't quite look the same when rendered in Vue 9. Vue 9 I notice doesn't have this choice in the atmosphere selection.
Any help appreciated.

Sometimes new Vue installs will default to re-using indirect lighting calculations. I don't know if Esprit has that option in its Render Settings.
Clouds have been tweaked quite a lot for version 9 scenes. Do you know what scale (Vue units) your options are set to?

Everything seems to have the same settings in both versions of Vue. Tried using 'Global Radiosity' atmosphere from Vue 6 on a single object and again not the same result.

Can you post a sample of Vue 6 and Vue 9 renders for comparison?

As from Vue 8 the indirect skylighting (skydome lighting gain) takes much more effect. Try playing with this.
Also for outdoor/landscape scenery you should take into account the "optimize for outdoor rendering" radiosity option, if you haven't already.
And more: The render settings differ. A Vue 7 scene imported to Vue 8 with "Preview" render settings will switch to "User settings".
I know this is about Vue 9, but when you come from Vue 6, a lot of things will have changed, like in the examples above.

Also, check your internal units if this parameter is accessible in Esprit. You may need to reduce the Aerial perspective to 1 to get the same atmoshere and scene scale. And Lars has a good point about indirect lighting contribution.

Ok i'm a heritic. I don't understand arial perspective, when and how to use it. What is 1 what is 10? etc

Aerial perspective is a setting found in the Sky fog & haze tab of the atmo editor, when using a spectral atmosphere. An AP of 1 corresponds to the atmosphere of our world, but you can notice lack of distant haze with an AP of 1 when your scene scale doesn't match the real world ( a standard 256m terrain for example., so you can cheat by using an Ap of 10 or more to simulate the distant haze. The slider only goes up to 10, but you can enter any value in the field.

Thanks for this. Having experimented with the skydome lighting gain, and turning on 'Optimise for outdoor rendering' it still doesn't quite have the same look as the original 'Global Radiosity' atmosphere in Vue 6. Seems a shame that settings can't remain the same when importing a scene from a previous 'inferior' version.

Yes. Would be nice if Vue 9 was downward compatible with older files. Maybe they should change the name of the program if it doesn't work the same as previous versions. But then there is all the legacy content one has invested in over the years that still needs to load somehow.
I have bought terrain material for v8 (and v8.5 thinking it would work in v9) that doesn't work at all in v9. And v9 material can't even load into v8. So I have to have both apps on the computer to have a complete workable solution.
