I want to switch between four lists of texture ( not in real time).

For that :

In Draw process and only one time.

I define the first list, like the reference.

I use pfIdleTex to have place in RM
I copy all the texture of another list to the reference with pfCopy fct

In Draw process for all channel.
I load all the reference list with LoadTex function.

2 questions:

I know that it's not for all channels but for all pipes.but i work on VEGA, if I have 2 or 3 channels by pipe, this error can duplicate the size of texture in RM ?

I remark some spike when i switch, so I add a pfuDownLoadTexture, It's work fine, So I think that pfFormatTex is not execute by the pfLoadTex
( is it true).

Another subject : The display list.

I look for information about display list:

hox it's works ?
What happen if I have more than 15 Mo of display list ?
If I have a large DB, with LOD and SWITCH, What's the better solution ?
