So i am dealing with this issue for quite a while already but the thing is i am trying to run java minecraft on my laptop but no matter what i do it always runs to unplayable state, no matter the version, optifine or not.


Computer is HP Laptop 15-bw0xx


Specs are:


  - APU: - AMD A12-9720P RADEON R7, goes up to 1048mb of vram and 2.7GHz stock speed


  - dGPU: - supposedly its AMD Radeon (TM) 535DX but it does not really work and barely ever does anything so

  lets say it does not exist


Storage: 

  128gig - M.2 speed ssd, hope i did not messed that up, running the game on it


  1tb 5400 RPM which makes game run even worse which well makes sense

 - 8 gigs of ram speed is 1866MHz



I used it on variety linux distros, multiple versions of windows, it all runs the same.


Attempted all sorts of java version, difference is minimal.

Oddly, Redstone builds actively running on Minecraft Java Edition caused issues for me from 1.11 forward. Upgrading to Windows 10 from Windows Vista and to Bedrock Edition from Java Edition however seems to have stabilized active Redstone builds while playing.

Bear in mind I have 8 GB of RAM at my disposal for Minecraft and have a NVIDIA GeForce 9800 GT for my GPU. Odd that upgrading my OS and going to the C++ Variant of Minecraft (Bedrock) fixed this.

Note: ram has hardly anything to do with speed. You wont increase your FPS with assigning more RAM (RAM just holds data like models textures etc.).

Your main issue is your CPU and graphics card. Those don't seem to be too great. So lowering your settings will really be the only thing you can do. Also try setting your laptop to performance rather than eco mode. Laptops aren't great for running MC. It's rather CPU and GPU intensive (despite it looking simplistic).

Good question!

First: if you're using Windows then you don't have to worry too much about installing Java because that won't make much of a difference. Minecraft provides its own Java runtime, so unless you start messing with profile settings then you don't even need to have Java installed at all in order to run Minecraft.

There are several things which you can do, but the most important parts are your graphics and memory. If your video card isn't all that great then Minecraft will have a much harder time running. So whatever you do: step one is to make sure that your operating system fully supports your hardware. In other words: make sure that you have installed all the right drivers, and grabbed the latest versions.

Next: Once you start Minecraft (the launcher) you can edit some JVM arguments in your profile. Edit it and find this option: -Xmx1G. This is the default. Since you have 8Gb you should raise that value to 6 or 7. This will make sure that Java can use much more memory than the default.

Now start Minecraft but don't enter a world just yet: check your options. Go to options => video settings, and change these settings:
  • Set the 'render distance' to 10 chunks.

  • Set the 'Max framerate' to unlimited.

  • Set smooth lightning to minimum.

  • Set 'Clouds' to fast.

  • Set particles to decreased or maybe even off.

  • Finally: vsync & vbo's: set to on.

This should help out a lot and make things better playable. If it's still not enough then start by decreasing the render distance even more to check if that helps.

6 - 7 GB of ram on vanilla Minecraft? Thats a LOT of ram, I use 2 - 3 GB

True. See, depending on the OPs specs it is possible that the video card (most likely cause for problems) won't be able to cope, which means that the Java runtime will have to do a lot of extra work in in order to keep up and thus process quite some data. And that data has to go somewhere. And once your OS starts handling all of that then you're looking at more (delaying) overhead.

But I agree: it's definitely not perfect.

Changing RAM really wont change anything. 3-4 is plenty for vanilla. Only thing i can think of that would be affected is the Garbage Collector. It won't have to run as often thus saving a tiny bit of work. But its not noticeable at all.

hey thanks for reply, unfortunately even after playing with those, results are pretty much the same thing, no matter what i did it was still unplayable, i would like to just give up but the issue is i played the game on much weaker machines and seen that too and changing those settings does not do a lot







EDIT: also i noticed that changing settings does not make a big difference

BTW to add something from my long term observations, i noticed that CPU seems to be "lazy" for some program or any processes it just does not wanna go fast and tries to power save itself, minecraft included and i cannot seem to discover what is the cause, no amount of driver changes did anything.

You might be able to find something related in your BIOS or computer settings, if you can access those.
