Literally, a 2D game is running at 20-30FPS and sometimes i get lag spikes of 1-10FPS

My PC has the power of a normal mobile device. So i guess this is not because i have a bad device. I think this also happens with some mobile players. Pixel Worlds is very optimized, running at 30-60FPS and there's more detail than Growtopia. I hope this game gets optimized.
