VS2013 express Intellisense is very slow… Unreal engine 4 [closed]

Question

Visual Studio 2013 Intellisense is SOOOOO DAYMMMMM SLOWWW... I have like an insane rig and it takes about 30 seconds to a minute to pop up the intellisense menus... Sometimes, it doesn't even show!... and i have to reopen the file to get it to actually come up? It's making learning Unreal engine really blooming difficult.

Is there any obvious reasons why this is so slow.

  • I've deleted my sdf file, but that did jack diddly squat.
  • I've run in safe mode

It doesn't seem to be context specific, it's just slow throughout the application.

Was it helpful?

Solution

If you use the unreal engine source code from git rather than relying on the unreal engine executable file project creation... You get an unreal batch file that creates the visual studio project for you.

When you do it the above way, it binds intellisense stuff and it is lightning quick now. I assume it's because VS was having to dive into files that were dll rather than just part of the project solution... (unpacked)?

A word of warning, it takes ages (30 minutes for me) for the first build doing it this way...

If you are unsure of how to use the source code from git, follow this tutorial: https://www.youtube.com/watch?v=usjlNHPn-jo&index=68&list=PLZlv_N0_O1gaCL2XjKluO7N2Pmmw9pvhE

It makes a HUGE difference!

Another thing that worked for me is to increase the C++ Max cached translation units to 15.
