What I expected to happen was...: Minecraft to load and run with the same settings I had applied in the previous update.
What actually happened was...:
I logged into Minecraft and it was a bit laggy. I had to turn down some of my visuals to help a little.
Steps to Reproduce:
1. Go to your visual settings in Minecraft.
2. Go to chunks and turn it past 15.
3. Notice its not the same.
4. Make sure your not on a fancy computer.
5. Place and destroy some blocks.
Possibly it was because of the update. The update has new details that could cause lag.
