I have massive lag on my Realm. Passive mobs are moving incredibly slowly with no redstone  or other things that might slow them down. My GPU goes to 100% while the game is still loading and never goes below 70%. Because of this my CPU is also maxed out at 100%. I can no longer play either in creative or survival.

I am also a Comp TIA certified Computer Engineer and know my way around a computer. I have Minecraft on my tablet, my phone and I also own the Java edition. 

The Bedrock environment was stable prior to 16.1.100 and 16.1.200 but now it is a resource hogging nightmare with this Dragon Rendering or whatever it actually is! The lag is so bad that the cows look like they are actually moving backwards and I have all of the fancy graphics turned off and the chunks down as low as they will go! And while your splash screen would have me believe otherwise, all of my Intel Pro Graphics Drivers are up to date!
