My GPGPU rant: OpenCL SDK
I need to use GPU to compute the physics. So I need to support Nvidia, Intel, and AMD. But OpenCL is way to go for it. But it's way inaccessible for amateur like me. So I need to find each vendor's GPGPU toolkit to make implementing GPU computing easier and AMD is one of the worst vendor to support GPGPU. Because their "open source" repository is either inefficient(as in high overhead) or doesn't work out of the box or completely broken. Well I admit that have nothing with supporting GPGPU on AMD. But it's still a time waste. Intel provide no GPGPU support. So I had to use OpenCL or Compute Shaders. But at least Intel has provided C performance support with their oneAPI profiler. You can get it online.
