I've searched all over for some similar issues and have had no luck.

My main question is if my expectations are too high for large assembly performance? For example when I open an assembly that's about 3000 components with some routing, zooming in and out is extremely choppy when I feel like it shouldn't be.

The computer I'm on is

• Windows 7 Ultimate
• Intel i7-2600k @ 3.40 GHz
• 16.0 GB RAM
• NVIDIA Quadro 4000
• SolidWorks 2012 SP5.0 w/ Workgroup PDM

I've tried everything recommended from large assembly mode to disabling aero features in windows and nothing changes. I have been testing out newer computers as well with better specs and it's the same. When I run the performance monitor during zooming and rotating everything is 30% useage or below.

Is this normal or is there something I'm missing?

Thanks, any help is appreciated.
