Sluggish performance in Maya 2018 LT Quad Draw

Steve Schulze

I've just upgraded (or downgraded as the case may be) from Maya 2016 to LT2018. In the Quad Draw tool I'm getting a noticeable delay when drawing polygons in the time between when the mouse is clicked and when a new quad appears. It's not unworkable, but it significantly slows down the process. By comparison, in 2016, I could hold down the mouse button, drag and quickly draw out an entire row of polygons. 

 

Maya runs with no issues outside of the Quad Draw tool. I tried switching between DirectX and OpenGL viewport renderers with no noticable improvement.

 

I'm using a powerful machine that should have no issues coping with Maya. I am running an AMD graphics card (Radeon R9 390) though. The drivers are up to date drivers, but I'm suspecting this might be the sticking point seeing AMD seems to have compatibility issues with everything ever. I haven't seen any mention online about problems there though - has anyone else running a similar card had any similar concerns?

Any ideas? I've searched around and hassled Autodesk's forums but haven't come with anything that looks like a solution.

Perhaps a viewport 2.0 issue? Have you tried enabling the legacy viewport via the environment variable, and using that?

It's a good idea, but I don't think LT allows for that kind of customisation, or at least it doesn't appear to be working based on the setup for the standard 2018 Maya.

could you try to export the object as obj and reimport back... i had some corrupted objects in the past and was able to repair them this way...

an other trick would be to use an alembic GPU cache as live object....
cache --> GPU cache --> export...

If it's like in regular Maya, collapse the history now and then.

I thought they improved performance of QD in 2017 and 18?

What I used to do was clear history on the mesh I'm about to use it on, then disable history from the top menu. This prevents maya from creating the many history nodes it builds up while working in quad draw, they're not useful; this speeds the process up by a ton. Just don't forget to turn history back on when you're finished.
