I really dont like this update. I mean, the stuff they added is great, but they destroyed my preformance. I went from 60 FPS to 0 FPS in a SUPERFLAT world. Minecraft 1.7 is unplayable for me.
Really? I get way better performance -- it's now playable without optifine for me. (Or did you have optifine installed previously, and so are going from optifine to no-optifine? That would explain the fps drop.)
It's weird, this seems to happen every version. Some people have way less lag, some have way more, and for some it does nothing. Mojang says that they tried to reduce lag, but that may be client-server (networking) lag that they are talking about.
Awesome update, but it's weird how for some people the FPS is much better, while for others, it's way worse. How can this be? It's so weird...
For me, the FPS got a little better, except sometimes when a lot of stuff is loading or I'm in a jungle or roofed forest biome. Btw, it seems chunk loading is slower now? It seems that way to me at least :(.
