I went from getting an average of 40-50 frames per second in minecraft 1.8.7, to now getting a consistent 12 fps with the new snapshot.

Still lower than expected.
I also found out that if you stay longer in one area, the display_update gets bigger and bigger in the shift+F3 chart.
I noticed that reducing the size of the window from maximized/fullscreen gives a lot more FPS even if reduced as much as 3/4 of the screen, while on previous versions this method didn't help much.
I have the same problem. Was getting about 35 FPS in 1.8.8, and am now getting like 7 FPS in the snapshot 15w31c. Running windows 7 with Java 7 (64bit) and a pretty good computer.
Confirmed it happening in 15w32a. Lot of "Tried to add entity (whatever) with duplicate UUID" errors.

Snapshots 15w39a-c fixed the issue for me: from 9 FPS to 12-23 FPS when moving, averaging 20 on already existing chunks, and that's even better than what I got with 1.8.8.
Why is this marked as 'fixed'? This is nowhere near fixed, in fact in later snapshots the lag has simply gotten worse. I am running a server with an i7 4790k CPU with 32 gigs of ram and 4 GHZ, but it lags tremendously in the newer snapshots when more than 4 or 5 people are online, compared to 1.8 where it could comfortably run around 20 or so. I think this should really be looked into, seeing as the server I have is supposed to be the best one for running Minecraft. Lag is a serious problem that no one likes to put up with. I cannot run any version later than 15w47c because of it.
"fixed"
I can't even play 1.9. After a few minutes of acceptable performances it goes down to 0-1 FPS for a few minutes. I just wait until the CPU is no longer struggling (it goes up to 100% usage) and then it runs ok for a few minutes, until it starts lagging again. And again.
It's unplayable, and this machine could run anything from beta 1.2 to release 1.8.
I already posted crash logs and such, in case you're wondering.
I appear to be experiencing this issue on my laptop, still up through 1.12. Downgrading repeatedly revealed the source to be the 1.9 snapshots, so I believe this is the issue. I have attached my crash report
[media]. My graphics card is not listed in the description (it's Intel HD Graphics 5500 GL version 4.3.0). When viewing the deug pie chart, over 90% of processing is being used up in root>tick>textures>unspecified.
Attempting to update my drivers results in a message indicating they are up-to-date. As well, they don't seem particularly old or outdated. I would appreciate any help you guys can provide.
yeah I used to get ~200 fps and now I'm getting 70 with the same video settings...that doesn't mean much for me, but what about the people without newer computers?
