I have a I73770k with 16GB of Ram. Might be a harddrive problem, but everytime i create new files it takes a while till the code highlighting works. Also, if i want to lookup a class that is used somewhere it takes some time for the IDE to find the original source file. For Example when you have an AActor and want to look up what a certain method does.
I am not a student, I work a fulltime job, but the amount of money but there is no way i can afford VS Professional or something like this. I felt like, when i used the Trial of VS Ultiamte, it went much smoother. Dunno why. There is also the VA Plugin, which again only works in professional. I would love to use some other IDE like maybe CodeBlocks or Eclipse or somewhat along these lines. As a big Fan of PHPStorm, i would also love a Jetbrains ide for C++ :). However, its probably not easy to get those running. sigh
Gamedev seems to be a very costly endevour, if you want to use all the cool stuff
