[MC-101] Minecraft Lag and General Memory Leaks

Basically every single update mincraft ever has they seem to give a better fps but then no it all goes downhill from there. When ever i am on my multiplayer server that I and some friends own (private whitelisted) its a powerful server and so there is nothing wrong on the side of the server but if I am in un explored areas meaning there are no player placed blocks and no torches and basically its just stock minecraft I can get 40-60 fps stable with no lag. As soon as i goto a base or somewhere that has been developed its every freaking second I move the fps drops to 0 for a matter of 0.001 second then back up to 40-60fps its so freaking annoying and has to be fixed or optimised, with my specs if I have everything on tiny fast and off I should be able to run minecraft without a doubt very smoothly, but no, if I install optifine the game runs perfectly in any enviroment i go in, normal render distance with fancy graphics is out of the question without optifine but as soon as i install that i can play with stable frames per second, on normal render distance and on fancy graphics. I know i have only spoken about my issue but i have seen this problem many times before.

Truth be told i think its very bad coding on mojangs part i mean if something goes wrong or an entity appears to be in the wrong place it gives that error message like 60 times and lower processors just cannot handle this. Please guys dont just dismiss the lower end pc users, if we had the money to go buying the top of the range pc's we would but it just isn't all that easy.

One more thing, if they made the game actually make use of the ram you give it then im sure that would clear up a few things i mean usually the game wont go over the 500mb limit whereas if it gave the ram a little more to do im sure that could help some of us out.

So you mean when the game updates it starts out better then slowly decreases? Is this per world, or does the lag transfer between worlds?

Like just always seems to be more stable fps wise when update but then I realise that its just as laggy as always.

Which videocard are you using?

matthew karl obrien 2012-10-24T18:55:33Z

That is something that off the top of my head i cannot tell you, if its very important and could help me like if its some sort of compatibility problem i could find out.

No offense, but this is a bug tracker. Bug trackers require very specific information on a single issue inside the game. Saying "The game's shit written and doesn't work on low end PCs" is more of a forum thing than something for a bug tracker.

Alexander you clearly have little intelligence so I will be nice, If you paid attention I was making the point that mods like optifine clear these problems up meaning there must be a problem right? I also mention that the game sends multiple error messages of the same thing in the same instance, meaning that less powerful machines have to put up with running the game and processing and figuring out what to do with these error messages, and in most cases the client just ignores them because they are not fatal, so they should not be sent over and over if nothing is to be done with them, if they wish for these messages to be sent they should at least add an option to turn off and on de-bugging. I hope this clears up what you were unable to see from what I believe to be a fairly descriptive and accurate diagnostic.

Well thank you for your incredible kindness by insulting me instead of staying on topic.
All I was saying is that sure, minecraft can improve and that's what this bugtracker is for, but exclaiming it's all shit, even if you can point to things like optifine that fix it, it's not a bug, it's a complaint, and should therefore be discussed on the forums.
If you've encountered specific ingame error messages which you believe are caused by bugs, then that's exactly what this bugtracker is for, and you're more than welcome to share what you've found.
But suit yourself, I will take no more time of your precious high intellect. /sigh

Psst lots of words typed, relevant information still missing.

Which videocard are you using? and if its one of those build in chipsets, names+numbers please!

I don't have a pretty mojang next to my name, but I imagine other important information might be what version of your video card drivers you are using.

Additionally, are you using any addons, or texture packs beyond optifine? Does this issue occur in single player or just multiplayer?

"every freaking second I move the fps drops to 0 for a matter of 0.001 second then back up to 40-60fps its so freaking annoying and has to be fixed or optimised, "

So you are saying that when you are in a developed area, when you move, there is a very very brief freeze up of your screen, before it resumes running at 40-60FPS?

This sounds like what my computer does when I have too many programs running, and I need to restart, but I'm too busy playing minecraft to do so. There are limits to how much backwards compatibility is possible. You do not expect to play a New Shiney computer game on a computer from 1997 and have it work, after all. The geeks are right.

But my question is.. if optifine fixes it for you.. . why don't you just use optifine and be happy?

Optifine never fixes it for me

Rickard Åberg 2012-11-01T12:59:46Z

I guess he wants better optimization which's always a good thing but as David says, use optifine if it works for you.
Personally I don't like optifine because it gives me weird render artifacts under some circumstances.

Pixelgraph 2012-11-02T11:00:53Z

I get weird flickering in the terrain when I move around too. Disabling Advanced Open-Gl fixes this for me.

Alexander Ypema 2012-11-02T11:29:30Z

I'm guessing OptiFine uses optimizations that don't scale well across platforms, which is why it's not implemented in the main code (yet).

Resolving as incomplete due to lack of feedback.

The lag is because of the blocks turning into items, and sand/gravel falling. It is happening in singleplayer, when you enter your world, the few minutes is laggy because minecraft try to load the things that should not be generated or exist on that way. When you exploring a new place in multiplayer, the minecraft detects the "floating" sand and gravel chunks, and the torches (ex: in NPC mines) are falling down because there like water flowed in or lava. If there is "floating" or not moving lava or water blocks, minecraft fix it, and it starts to move, and that is why it is causes lag. There is no way to reproduce this problem, mojang should make the world generations (it could be hard because in minecraft, there is a lots of weird world generations, that are just random) better, so there is no gravel generating in floating peaces etc.
