This one is really strange: Whenever I have a null selected, my interactivity slows to a crawl. I can't even switch between tools without having to wait about five seconds for AE to respond. Also, I can't edit the Null's motion path without experiencing lags between five and fifteen seconds. This is really hurting my productivity, and have just noticed it starting to happen.
I've made sure to use half-resolution previews, the region of interest tool and I'm disabling all other layers in the comp, but the problem still persists. The only thing out-of-the-ordinary is that I'm working at 99fps, since I'm doing a work-around for Trapcode Particuar that the Null is driving.
I've made sure all of my drivers are up-to-date, and am really stumped as to why this is only happening with Null Objects.
If anyone has any thoughts, please let me know.
My specs are as follows:
After Effects CS4
Windows 7 Enterprise
Intel Core i7 920
Nvidia 8600 GTS
