High CPU usage for the Hearthstone program on Macbook Air M3 with 16GB ram. Every other time that I run hearthstone from the battle net launcher, it consumes a massive amount of CPU. Currently the client is showing about 630% CPU usage. When this occurs, I will normally close the client and restart. Then it acts normal… using a small amount of CPU. I just did it and started a new game… CPU usage is down to 50-75% like normal.
