Dual Xeon - 40 Cores. Painfully Slow Shader Compiling.
Im having extremely slow shader compilings on these latest versions of UE4. A compile of 5000 takes me about 15 minutes. Moreover when i edit any parameter in the material editor, the compiler starts compiling. and any other change just adds and increases the number to compile. Its not possible to work like this in any efficient way.
Please watch this screen recorded video as its self explanatory - https://www.youtube.com/watch?v=Q_E45cUha2s&feature=youtu.be
Any suggestions on how to fix this are welcome. Ive searched all over but cant find any viable answer, or barely anyone havign similar issue. Bare in mind that i did not have this issue on previous versions. Ive also tried removing and re-installing UE. Building from source (v4.19 - 4.20 - 4.21) with no improvements. Thank you for reading.

Ok, I finally figured it out. It was a software called Incredibuild that was slowing down the compiler. I installed it at some point as Visual studio was claiming it needed it to build UE4.. (bare in mind im not a programmer so i blindly follow instructions and follow error messages)
So that software has just been sitting on my computer. However when i was compiling, i checked the processes and incredibuild was running under UE4. Moreover it seemed to be using just one core. So i uninstalled it and now everything is smooth again. Glad i managed to resolve it, but also cursing incredibuild for behaving in such a way. really wasted loads of my time this past week.
Your most welcome, im happy that the post helped! And glad you agree that other programs should not be able to take over tasks performed by UE without at least a notification.
