Low FPS minecraft?
I recently tried to play some minecraft again, I used to play on some old laptop a few years back and I dont remember much lag and I even remember using higher res resource packs and i think I even used shaders sometimes.

But now on my (I'd say fairly decent) computer I have now I cant seem to stabily get upwards of 60 FPS with decent graphics settings (I've tried Optifine and giving Minecraft more RAM) when I can run games like GTA V on highest graphics really well I'll put my specs below and i would greatly appreciate any info or help, Thanks

OS - Windows 10 Home 64-bit
CPU - AMD FX-8320
RAM - 16.0GB Dual-Channel DDR3
Motherboard - ASRock 970 Extreme4
Graphics - AMD Radeon R9 200 Series
Storage - 1TB HD (For games)
256GB SSD (For windows)

(Sorry if this was in the wrong place or anything, I've never used a forum in my life)

Remember to install 64-bit Java incase if you haven't already.

Open task manager and do whatever you do, and check what your CPU and GPU usage is, then say the usage percentage. Are other programs taking up any decent bit of your CPU?

Is it when you're looking far out in the distance?

Also since you have Optifine, turn on Lagometer for a bit when the FPS steadies, then press F3 and screenshot it.

What graphics settings do you have?

Last I recall, Java can't utilize ALL of your PC, though recently it apparently allowed use of a couple more cores, or something along those lines.

Also, AFAIK, most of Minecraft is pretty much CPU, even the visual rendering. I say most, but there's a decent bit on the GPU but it's mostly CPU.

I had installed 64-bit java already.

My avg CPU and GPU usage are:
Not running minecraft - CPU 5% and GPU 1%
Running minecraft- CPU 40% and GPU 40%

Heres my screenshot of the lagometer on the F3 screen when i was stood still and my FPS had somewhat steady'd out: https://imgur.com/a/P0E0MS5

If your talking about my graphics settings on minecraft well I've been constantly trying to change it around to see whats really pulling my FPS down whilst just playing the actural game.

Yeah I seem to remember that but as you said if minecraft can use multiple cores I do have 8.

Im just so confused why i cant run such a bad looking game on decent settings xD and thanks for the reply. :)
A few more, not all. If your CPU is going 40% and never goes higher, than your CPU will never perform past that for Minecraft. AMD isn't exactly peak single-core performance in the first place; that's Intel's spectrum.

It's complicated for the reason why, but in a nutshell it's because Minecraft was made in Java. It's a good idea for the time it was back then, but nowadays C++ is usually better. But it's not like it could just swap over. The language isn't the complete reason either though. It also goes down to the devs' own code and other stuff.

And frankly you *can* run the game on those settings. Just not as much as you want it to be.

Turn off antialiasing if you have it on.

If I may pop in, back when I had this issue with Minecraft and with a similar system (I have an AMD FX-8350), it was due to overheating [and needing to dust out my system].

These days, there are a bunch of protections against heat and if your system is too dusty or overheating due to fans not working/hot weather/etc, it will throttle down your capability/performance, so as to keep the heat down.

Try dusting out everything and double-checking all fans are working well. Make sure everything is seated tightly and wires are 'mostly out of the way' for airflow.
For me, after doing this, everything ramped up to higher CPU %'s and the game flew at over 200fps... woot

I'd also run a few tests on your HDD and move the game to the SSD - this will let you know if your HDD is experiencing issues like corruption or getting too old, etc - the game streams a lot of data over time from the drive (as it creates the world and saves it to disk as you move around).

Just shooting out some ideas... GL

Yes I'll most likely try this as i havnt really cleared out dust ect. in a while although it dosnt seem to be getting to hot tbh.

It is actually on my SSD the only thing on my HDD is all my many steam games.

Thanks for the help :steamhappy:

you dont have a FPS issue . . . you have a caching issue.

use the default texture pack, turn down the rendering distance, play a smaller map, or buy a new PC.

Im using the default texture pack, I have been moving my render distance up and down to try and find a good balance between FPS and being able to see, im not sure what you mean by a smaller map and I dont need a new PC at the minute as I can run all other games i play good enough for me apart from minecraft which i should be able to run.

No problem, it was just an idea.

If you want to try, you can also Disable any "Power Saving" or "Green" type of optimizations, both in Windows and in the BIOS for your Mainboard, if you wanted to. If the game is actually going 'really fast', your system could be still throttling itself down, to keep from overheating (even though it is not hot yet). Not saying that Heat is your issue, just throwing out the concepts that I dealt with once.

Also, have you tried completely uninstalling/erasing the game and reinstalling it fresh?
If I missed you mentioning that, sorry.

GL with it
