[langtitle=fr]Will there be a 64-bit version of SE 2D Drafting?[/langtitle]

When opening a 25MB .dwg file, SE 2D Drafting ST5 is much longer than DraftSight 64-bit.
Worse, the zooming is very slow with SE while it is seamless in DraftSight.
Virtual Memory size is between 930 000 and 1 200 000 KB with SE vs about 730 000 with DraftSight for the same file.
Is 64-bit the reason for these issues?
If yes, is a 64-bit version of SE 2D Drafting planned and when?
