I have been using SW for years fine on this laptop with specs as followed
Intel Core i5-3230M 2.6GHz
16Gb of DDR3 RAM
Intel HD Graphics 4000
Its not the best computer for this kind of stuff, but it only starts slowing down when I get into moderately large assemblies. Recently the program starts running really slow as soon as I open or create a sketch. It's so slow I can't get any work done. I've checked the driver and it hasn't had any recent updates. I updated it anyways but that didn't solve the problem. Any input would be greatly appreciated.
