Open the statistics window and see the performance statistics of your game. Basically and basically Draw Calls is determined by your game partition. For example, FPS decreases to 60 with more than 2500 callbacks on most PCs.
Suppose your card is 128x128, if you use 16x16 tiles, you need 64 nodes, otherwise, if you use 32x32 tiles, you need 16 nodes. More nodes mean more load. Just check the stats and get visual effects under control for better performance.
