What is OpenCL and what does it have to do with DForce?
I am back to using old Lenovo right now, but first it had an OpenGL issue which prevented DS from opening. I changed the video driver to a non Microsoft one and that fixed that issue. Now when I try to use DForce it complains about OpenCL.

It's a generalised set of routines for using a GPU to perform mathematical functions, dForce uses it to spare the CPU (assuming your GPU supports OpenCL 1.2+) from having to do the simulation. There are OpenCL drivers of Intel CPUs if your GPU isn't up to the task.
