UE4 Slow Shader Compile

Development Rendering

As per title, I’m experiencing slow shader compile times (approximately 10 or 11 shaders per second).

My workstation rig is a Ryzen 3900x 12 core processor with 32GB 3600 RAM.

I’ve already googled this problem and found various suggestions that haven’t worked. From what I can tell, compiling shaders is set to a low priority for the CPU and so it doesn’t utilize the full power of the CPU (mine when compiling shaders and multi-tasking while waiting never goes above 20%).

Has anyone else solved this problem and resolved it?

Blockquote unless you pay for incredibuild it limits the # of cpu cores it uses and will cause slowdown issues

Go to Extensions > Manage Extensions > Uninstall IncrediBuild > Modify Visual Studio

And it should uninstall IncrediBuild. I can verify this works. My CPU is fully utilized now when compiling shaders.
