Hashcat on Windows 8 vs The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali)

[Eiplanner]

I am currently running hashcat in my Windows 8 environment, inside the command prompt terminal.  Is there any downsides or speed compromises I will be giving up by not running hashcat from The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) instead of Windows?  I am working on a 7z file crack and am pretty sure I need the OpenCL maximized.
