I wasn't sure where to post this thread, so I posted it here. Move it to appropriate section, mods.
So on singleplayer and multiplayer, worlds render incredibly slow. Infact, it's been doing this since 1.3.
I have tried allocating more ram to Minecraft (I'm not giving it more than one gig, any more than that is stupid and un-needed,)
I tested it with Optifine and vanilla, it does the same thing.
Don't tell me to lower my render distance. I am looking for a great view, not a restricted foggy one.
And yes, my internet is good enough to render a multiplayer world.

If you put it on far render then you'll need a 64 bit OS and 64 bit Java

Yeah, I have 64 bit Windows 7 and 64 bit Java right now. It still does the same thing.

Yeah, the world seems to load a bit slower for me, too, however putting "Multi-Core Rendering" on in optifine fixed the problem, but then again I have an 8 core processor. There is no way minecraft should require 8 cores (I don't even know how many cores optifine uses, it might only be 2-4). There are multiple world loading options in optifine, did you try them all?

On a side note, allocating more than 1GB to minecraft is not "pointless". If you're setting off large amounts of TNT, the more RAM, the better. I also found minecraft works much better on 6 GB than 2 GB, just generally.

But then again, every computer is different.

Well yeah, I mean I can see why allocated more than 1 gig can be of use. But for what I do, I don't really need to in all honesty.

Most don't

...Unless you really, really, like TNT...and sending yourself to the moon.

What options in optifine have you tried using?

I found that putting it on smooth renders the fastest for me. Other than that, all highest settings.

If you haven't already, then try these settings and let me know how it works.

In "Video Settings" set chunk loading to "Multi-Core" if you have a processor with more than one core.
In "Video Settings > Performance" set "Chunk updates per frame" up to 5 if you can without lag, that also speeds up loading a bit for me.

I thought I remember that there were more chunk related options, but perhaps not. Playing with worlds on a SSD or fast HDD would also speed things up.

From what I've seen, slow loading is pretty common, even on fast computers.

I'll try that when I get on my main computer. And yeah, with a quick google search everyone seems to have the same issue.

Do you mean when chunks are genorating or re-visiting a place? I think the issue is that its just minecraft being minecraft =) . I tend to find on my laptop the world renders at the same rate i just get a lot less fps with the higher graphic options.

Nah, I mean in general the chunks tend to render slowly, except....
The chunks are no longer rendering slowly, however I still need to get incredibly close to unrendered chunks to render new ones, which is still just as annoying.
