DotNet / Poor performance using multiple VertexArray

« on: March 17, 2016, 10:55:08 pm »

Hello,

I'm actually making a tilemap using VertexArray, my tilemap is split in multiple chunks

Each chunk has it's own VertexArray

One Tile = 16x16 pixels
One Chunk = 128x128 tiles = 2048x2048 pixels
Map = 2048x2048 tiles = 4194304 tiles
Number of chunks = 256

And i'm getting 12fps when i render all the chunks, it's really bad performance for only 256 draw calls...

Here is a ready to use project, so you can test: https://bitbucket.org/Scellow/projecttr

Is there something i'm missing? I also tried using RenderTexture but i get same result..
