Rx 480 low FPS in minecraft??

My rx 480 has about 350 frames at 1366*768 resolution on minecraft but benchmarks on YouTube shows an rx 470 gettings 600-700fps at 1080p

  1. Minecraft is almost completely CPU bound (unless running shaders), so your CPU strength matters much much more than your GPU.

    cpu bound game


    you just cant drop in a good gpu and expect those fps when the rest of your setup is weak

    complete specs?

    My specs are:

    H110m-A mobo
    620w PSU
    I3 6100
    12gb ddr4 (2133mhz)
    And the xfx rx480 8gb
    1tb hdd

    MSI afterburner shows my CPU never going near full usage, about 30-50%........ GPU usage jumping all over the place

    It is most definitely your CPU. The only thing you can do apart from getting a better CPU is get Optifine and turn down smooth lighting and render distance.
  5. Well, you do have less FPS than some youtuber and it's because of your CPU.
    But, here's one thing you have in common, your 350FPS and his 700FPS are the same. Let me explain.
    Your monitor is at most a 144Hz, probably even less, that means it can refresh 144 times each second, thus displaying 144FPS.
    Having FPS above that is not effective, because it's not getting displayed on the screen.
    Yes, it does improve smoothness a little bit, maybe when going from 150 to 300, but 300 to 700? I don't think you'll see a difference.
    If you want to test your GPU, download a real game that has a benchmark, like Tomb Raider.
  6. I guess you're right in saying that his monitor can't display over 144hz at most, but I too would be concerned if I was only getting half the FPS I thought I should be getting, and I certainly wouldn't brush it off with saying "they are basically the same thing".
  7. That is why I told him to test on another game that has a benchmark.

    Doom runs at 120-140fps Ultra Settings at 1080p as it's supposed to, so i guess it's just minecraft? Also my monitor is 75Hz
  9. Yes, it is because Minecraft requires a good CPU to get good frame-rates, due to it being poorly coded (though it is still a very fun game especially with mods).
  10. Just to add to the CPU thing, you might see two scenarios using MSi Afterburner:
    1. 100% usage. This is the obvious one. Your CPU is being worked like a dog by the game. The game needs more CPU.
    2. You see less than 100% usage. You are still CPU limited. This might happen when your CPU doesn't have the type of performance the game needs. It's not that your CPU is bad or slow, it's just that it has the wrong type of capabilities than what the game needs most. An example would be a CPU that has 8 cores but each core is slow, while the game needs very fast cores even if you only have 4 or them.

    So don't assume less than 100% usage means you have plenty of CPU, it might mean that, most times it does mean that, but not always.
  11. He can't have less than 100% on an i3-6100
  12. Yes he could. Minecraft by default only uses 2 cores, and since i3s are 2c 4t it SHOULD only use 50% max, but I've noticed that CPU/GPU usage graphs sometimes aren't the most accurate anyhow so it really doesn't matter.

    My i3 runs about 30-40% load and gpu just goes everywhere I can't tell you where it's at.

    Benchmarks on youtube show a Pentium g4400 (2 core 2 thread) and the rx 480 getting more frames on shaders than me at 1080p and i'm at 1366*768.

    My i3 6100 is either getting out performed by the pentium 4400 (lol) or my minecraft is broken. I say my minecraft is broken because the i3 6100 has about the same single core as the i5 6500 and just less multi core (correct if wrong) so if it's just on the two physical cores it shouldn't be a problem?

    I know shaders are more GPU dependent so it might be something with my GPU but if it is my GPU, it's just on minecraft. Every other game runs just as good as every rx 480.
