Hi All: I'm doing some high rise building in detail mode. And I found that eQuest becomes kinda sluggish or not that responsive. Sometimes, the case file can more than 500,000 lines thus it takes more than 30min to load. If I change a parameter, it also takes quite a while to update. My computer is i7-2600k with 16GB in Windows 7 64bit. The CPU loading is just around 25% - 30%. Does anyone know how to make it faster or more responsive? Thanks.
