OpenJDK Platform Binary permanently consumes 100% CPU. I've tried setting priority, affinity, selecting between Nvidia and Intel, allocating more or less RAM, but no improvement.
Let me put this into perspective:
On Windows 10, I get 1 or 0 frames per second all the time with 2 render distance and all settings turned low.
On Linux, I can keep all settings up, and play on 8 chunks render distance with a stable 60 frames per second, even over 100 fps with Vsync turned off.
I don't know if it is a specific version of Java causing this or what, but I can only play Minecraft on Linux at the moment.
Just to avoid confusion, I dual boot Windows and Linux. So all this is happening on the same laptop.
Thank you for your report!

Performance drops are expected to happen between versions, especially in snapshots. Simply stating that "My game is laggier" is not helpful for Mojang to diagnose your issue. If you can pinpoint a specific cause when lag happens for you, please open a new report for that specific issue. If you think this might be a hardware issue please contact Community Support as they might be able to help with your issue.
Keep in mind that Mojang is constantly optimizing the game and simply playing the game provides feedback to Mojang on which parts cause performance issues. To learn more about this, head here (section "Telemetry") for more information.
