I get solid framerates, generally between 65 and 90 fps, but water flows slowly, blocks sometimes get 'unplaced' or placed twice, it takes like 3 seconds to throw an item, same to pick them up, chunks often refuse to load and mobs move at around 1 frame per second. It also takes around a minute just to load the world once I've started up the game. I don't know exactly when this started happening, somewhere between yesterday and the day before that. It's the same in both the newest snapshot, an older snapshot, 18w47a, and 1.13.2. Minecraft is only taking about 25% of my ram usage, so I'm not sure what's wrong with it.

Video Demonstration

I have a relatively good setup, an AMD FX-8320 Eight-Core processor with a GTX 1060.

please post the video on youtube or somewhere that doesn't require people to download and play a video on their computer

It shouldn't require a download on the dropbox website, but here you go.

Please send a video with Alt+Shift+F3 debug screen enabled

hope this helps. Also included some task manager shots in there.

And before anyone asks, yes the game runs just as poorly with illustrator closed and open. I know it's a resource hog, but it doesn't seem to be the issue.

The problem is the tick rate which is too low. Java doesn't get enough CPU power

RAM doesn't seem to be the problem

Please post the JVM arguments.

You also can try enable/disable vsync, vbo and the fps limit

JVM arguments are: -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

Only thing I've messed with is the ram allocation, from 2 to 3 to 4, but nothing seems to change it. I believe they removed the vbo option in the newest snapshots, also lul

Also, the Vsync didn't do anything, nor did messing with the fps limit

Update: In the newest snapshot, 18w49a, worlds don't even load.
