PVRTexTool sets the process priority of astcenc.exe to high causing computer to freeze

Hi, I’m using the PVRTexTool libraries to encode textures with ASTC in Windows but for some reason, it sets the process priority of astcenc.exe to High and since it uses 100% CPU this causes the computer to become completely unresponsive when encoding textures (which can take hours). Could PVRTexTool be modified to leave the astcenc process priority to normal?

Thanks!
