Hi All, I have it working based on the code from the mentioned blog. for 4K dynamicly updated objects (a fully 3D model) I am getting 160fps. I will try to put more thoughts on it how to optimize, perhaps cutting out the matrix usage and use vec3 and quats instead, and want to try with latest submission from Robert with the VertexAttribDisvisor StateAttribute now. Will ping you with the findings ..... Stay tuned :-). And thanks for the support so far
