The fog causes rollbacks

There seems to be no way to turn the new feature called "fog" off, and it changes the entire feeling of the game, as it makes the entire game gloomy and dreary instead of fun and radiantly colorful. Everything is grayed out! Blacks aren't black anymore, not even on moody setting! And as an extra bonus, it causes loads of miniature lag: Ever since the new update, I've been experiencing tiny, miniature rollbacks. These can be seen when looking at the sun or moon as it moves forward during the day and then jumps back slightly before moving forward again. It does advance a little bit each time, but still, it makes it feel like I'm constantly lagging minutely. Enemies aren't as threatening since they also roll back slightly (which I technically don't mind since they can't kill me anymore), but it's rather bothersome that I sometimes have to mine the same block twice or place the same block twice, which is really, really annoying! Not to mention not being able to fly with elytra because I fly into walls and die.

I seem to recall you originally forgot to add a button in the video settings for clouds to be toggled off/on back in the day, and now you seem to have forgotten to add it for this new feature called "fog". It makes the entire game laggy, and I'm experiencing a lot of rollbacks due to it, having to re-place and re-mine blocks over and over just because the fog is lagging out my game.

The fog also makes all details on any build disappear, so I feel like I'm running around in a 2D game, not a 3D one, due to all the details being smoothed/blended out. Some googling says you can remove fog by installing extra stuff from third-party vendors and that they need to be manually updated to current versions (and it may take them some time after updates to renew their mods) to be able to remove fog, but I must admit that I find this unacceptable. You are the creators, and you should be able to remember to make new features toggle-able "on" or "off" when they impact the devices/machines they are played on so heavily that they cause such severe lag. Usually, you can just tweak the setting by lowering the quality until you have fixed the bugs causing problems, but for some reason, even with all settings on the lowest, the fog can't be removed, nor is there any command to disable it on Java. Please fix this!

It would be different if your Minecraft Launcher had a direct link to where to install the mods from a safe place to make the game playable (i.e., turn off fog), but as it stands now, players have to google and hope to find something that isn't full of malware! So please hurry up and add a command or a button to turn the lag-causing fog off! You did so for clouds, so please do so for this "fog" too!
