Hi Michael,

Quick question, since beta is 64 bit and now it loads a very serious amount of CAD data, also exports impressive size obj's, now the speed of viewport is a serious bottleneck. I work in medical robotics company and our cad assets are pretty huge to say the least.
Any inside on view port performance future?

Thanks,
Roman
