I have successfully made an opengl 3.x animation in golang. However; the frame by frame update is noticeably slow only after 20k textures rendered. All the sprites do is simply move from the left side of the screen to the right. Keep in mind they are all on top of each other because i was too lazy to randomize location.
I have an updated PC that can run GTA5 on high settings but cannot display 20k sprites (quads with textures) in opengl3 environment??
I must be doing something wrong here. Maybe I need to pack all vertices in one VBO instead of a new vbo for each object? I bindbuffers every object as well. I'm not really sure what is causing this bottleneck. Can someone help as i'm not sure where to go from here?
I have attached my code as reference for anyone that can give some tips on speeding up rendering of 20k sprites in opengl3: http://pastebin.com/SHQtRPn7
