Performance issues - compiled UE4
Why compiled Development Editor (which according to docs is "Release") from UE4 source is way way slower than released one from launcher? I'm talking big difference here.
I compiled 4.13.1 from GitHub.
P.S. I've seen others having the same problem.
P.P.S. Question is not about compilation time, but how slow compiled-from-source editor works compared to downloaded one from launcher.
I found out how to build UE4 from source to be as fast as binary version provided with launcher, so for reference I'll post here. It takes several steps:
Thanks for the report. What you are seeing is a consequence of the difference between using the binary version and the source version. The source version generally has more to do when the project is launching compared to the binary version. While the difference is noticeable, it is also expected and therefore, not a bug.
My recommendation is that if you do not need to make source code changes, go ahead and use the binary (launcher) version of the engine. However, if you do need to alter engine code, the longer loading and compile times will be a part of it.
