So I have been writing this Chunk system for my tilemap game the last couple of days for maps created in Tiled.
My map dimensions are 12288px x 3072px => 384x96 tiles with 4 layers.
One of the most important criterias was that the map had to perform great on any screen size.
What I managed to get was 60 FPS below 1920x1080 and about 32FPS at 2560x1331 with an Intel i5 and Gefore GTX650. At 2560x1331 I achieve this by rendering 113 chunks every frame and checking only adjacent chunk collisions ~30 collisions, with a chunk size of 8x8 tiles with tiles of 32x32 pixels.
What do you guys think, is this good performance for a HTML5 (WegGL) game? or compared to what Phaser has to offer out of the box.
