I will render around 100,000 vertex with one VertexBuffer of just one vertice using DrawInstanced(), D3D10_PRIMITIVE_TOPOLOGY_POINTLIST
the output of the vertex shader is a random ID the can go from 0 to 2^32, and a random score that can go from 0 to 2^32
Various vertex can output the same ID, the total score of the ID is the sum of all scores with the same ID
I want to know which ID has the highest score, just using the GPU
