I play Minecraft Bedrock on a laptop with an Intel Core i7 13620H processor. When the game is in the menu it usually uses around 30% of the processor, (which already seems high to me) the biggest problem is when I enter any of my worlds as the CPU usage shoots up to 80 - 90% something completely exorbitant considering that much more demanding games require less CPU usage.

I hope these comments will be of help to correct the respective errors and provide a better game experience. If you require more information, data and specifications I am willing to provide them.
