What would be considered the minimum hardware requirements for PC to use the Unreal Engine? I’m getting a 100% CPU usage with the ShaderCompileWorker. I have a pretty ‘decent’ setup for gaming - but it is not on the higher end. The memory does not appear to be taking much of a hit, just the CPU load. Currently I cannot even get into the engine to start creating my Project, it tries to initialize the project and gets stuck at 39%. I tried to end task and start a new project and it stops at 39% again. I waited about 10 minutes and it never moved and appeared to freeze as the typical sequence of dots displayed after “Initializing…” seemed to just freeze and no longer signify it was continuing with the operation.

It’s shader compilation thats absolutely 100% normal, and 100% CPU usage is what you want to have as it means compiler efficiently use your CPU as fastest as it can. Let it complete it once it’s done it will be cashed and you dont need to do it anymore (or else you open other new large project that you UE4 didn’t touch yet).

There really no minimum requirement on shader compilation, it just matter how fast it gonna complete and even with powerful CPUs it can take longer time.

If oyu look for hardware, don’t look on gaming PC hardware youtube videos that gonna tell you CPU cores don’t matter, you are game developer not a gamer at this point and in this use case more cores the better, in many cases regardless what enigne you use you gonna run heavy duty tools which in many cases scales infinity on all cores

Also if you want to observe compilation process run your UE4Editor.exe with -LOG commend line option, this will open log window and it will print out what it is compiling

Minimum system requirements get a little bit higher as the Engine version number increases, but not a big difference.
You can squeak by with 16 GB RAM and a quad core 2.4 GHz CPU and yes I am even running it on a 7-year-old GeForce 650 GPU.

Getting stuck at 45% or 39% or wherever, is normal as it is one of the lengthier parts of the process. It should not get stuck for nearly as long after the first time because the shaders should already be compiled unless your shader cache or derived data cache were cleared or expired or got replaced by another project being worked on.

If anyone is having issues, I was having the same problem, just hanging on 52%, CPU 100%

First i thought it crashed and re installed it…

just hold on , mine took about 20 min!!!
