Right so I've been playing a 1.9 P3 world since yesterday and today I started noticing that I would get these lag spikes that would freeze the game for a few seconds and then after that I would go from averaging 150+fps on far+fancy+smooth lighting to being lucky to get 15-20fps on tiny+fast+default lighting. I suspected it was that bug that people were running into that caused huge amounts of lag, but was curious as to why I was playing just fine for the last two days without a hitch. I noticed that I only got these massive amounts of lag when I was near-ish my home, but what I didn't notice was the fact that as I headed in a certain direction, it got worse.
I ended up walking in that direction, not knowing or suspecting what I would find. My FPS steadily dropped from around 150 to 20, then 10, then I was getting something like 1 fps. I exited the world and loaded it up again and took note that it took considerably long for the game to load the file. Then I saw it. As the terrain generated, for a split second I could see a huge mass of sheep under a hill. Checking F3 (which took about 20 seconds to do, I was getting maybe one frame every 5 seconds) It read there were 15334 mobs in front of me. It wasn't the rendering that hurt my FPS, as when I paused I would get a steady 200 fps while looking at these mobs, but it was the massive amount of physics and AI calculations murdering my CPU.
How the forget did fifteen thousand sheep get under a hill. I will attempt to get pics tomorrow.
(I typed this up last night at like 1AM but didn't post it, and I'm only posting it now at like 10:30AM)
