A while back when I first started Viktor, I made the first level into one layout. The level took about 5 minutes to beat, so it was relatively long (maybe 40,000 x 40,000 layout size). I had a friend who had a non web-gl pc to test the game, and his fps was in the low single digits. When I split the entire stage into 10 "mini stages", his fps dramatically improved (to the high teens; low 20s). So my question is this:
If you're not adding more "new" images by creating large layouts and instead reusing 90% of the sprites you're going to have in every mini stage anyway, is there a bad reason to have a super large layout like this? I did a test to see the memory and CPU usage, and the memory usage was virtually the same between the full size layout and the mini layout. The CPU, however, did seem to jump a fair amount (went from 30 to about 60), but I think that's normal given that a lot of sprites, even though being reused, all had sine behaviors, etc.
I personally have no way of testing this because I get 60 fps no matter what, but Viktor had some minor complaints on Steam that would experience certain framerate related issues that were otherwise untestable on my end. I'm assuming due to the fact that some pc gamers don't have a webgl-enabled graphics card.
