I started using Visual Assist X in my CUDA project and it helps navigating code a lot! Makes a huge difference. The only problem that i've had so far is the following. In my CUDA Runtime API project properties i have a define set that determines whether some bits of code should be compiled or not. The VA doesn't see this define and grays out those sections. I would be totally fine with VA not handling any code coloring for the defines but cannot find how. Tried messing with the newly created cu.tpl file, no effect.
