3ds max 2014 Viewport

[eyepiz]

Hi all,

I'm working on a large arch viz large project and am having a viewport issue. I have set up every thing pretty efficient. I used as much proxies and merged objects textures as I could, however, my viewport runs at a smooth 70 frames per second ish but ever 10 second or so it micro freezes for a second or two.

any Idea what could cause this?

I would appreciate any assistance.

I think I figured it out, It looks like it related to my space mouse pro.

anyone else have this issue?
