I downloaded a software that uses simple D3D drawings overlayed on my computer screen. I noticed that the software was using an unreasonable amount of my RAM (about 8GB of RAM) and CPU (40% of my CPU). This led me to suspect that the software was mining cryptocurrency under my nose. When I asked the developer of the software for an explanation, he told me that it's because my windows version (currently 1803) needs to be updated to 1809. This just doesn't make sense to me. How can that cause the software to use 8GB for simple directx drawings? I could really use some help here.
My specs: processor: intel i7-6700HQ Memory: 16GB DDR4
