Laggy move with Shift override of Ortho and V-Ray

[SamPage]

In Rhino if you are attempting to move a large number of objects (say a 100x100 array of rectangular curves), turn on Ortho, select your objects, Move, pick a point to move from, then hold down shift to override the Ortho and move the mouse around a fair amount. Over here, the move starts lagging well behind the cursor. The same move with Ortho off is perfectly fine. Load protect V-Ray and try again, the lagging goes away when using Shift to override Ortho.

Thank you for pointing this out!
The problem actually affects all modifier keys. Our dev team will look into it.
As a workaround for toggling Ortho mode, use F8 instead of holding down the Shift key.

Kind regards,
Peter

has this been fixed already? it is a very annoying bug that makes working in Rhino a real pain. I would really appreciate if this could be solved with a hot fix. I use alt a lot to temporarily disable Osnap and even moving a single curve in an otherwise empty document becomes slow

One of our developers is currently working on it as well as a couple of related issues. Will post again when a solid solution can be offered.

Kind regards,
Peter
