Setting Up Leela Chess Zero lc0 25.1 directx 12

this version of lc0 was intended to use with directx 12 card. From Leela's page, this variant is for non NVIDIA card windows 10. but when you try to run the engine on dual graphic card laptop, for example, mine, using NVIDIA Geforce 840 and Intel Graphic, it would spit "Dx error: Unspecified error (c:\projects\lc0\src\neural\dx\shader_wrapper.cc:122)". That error would disappear when you set lc0 to use NVIDIA High performance from NVIDIA control panel Settings.

change lc0 settings from NVIDIA control panel, use High-performance NVIDIA processor
