How do you make PC Minecraft look like Xbox?

You can change everything in the game's settings. (Escape button while in-game > Options)

You can change the sensitivity, the Max Framerate (If you get a higher framerate that you actually want to have, it depends on your PC specs!) and brighter too!

You can even bind your Xbox controller to the game's buttons. I did that and I had tons of fun playing Minecraft with a controller.

You can have resource pack to change any texture needed for looks. For brightness, you can go to the video setting and experiment a bit.

You can use 3rd party app for controller to hook up with Minecraft. If the sensitivity is too high, you can lower it by going into control settings.

Unfortunately about the frame rate, it depends on your PC specs.

There is nothing to make it look like you've questioned but the truth is that you need to find out the patches to make Xbox look like PC also you have to look in the internet and try to transfer SD card to patch it to the Xbox so you can somehow make this work for now, also regarding to that, you need to make this possible so you can be able to be better with the PC looking Xbox. The possibility for to get Xbox to look like PC is 23.6% of chance if you had that right.
