Hello all! My friend and I both recently purchased the R9 270X graphics card for each of our computers. While his computer in Minecraft reached a new FPS of over 300 frames per second, my card is still stuck at around 60 frames per second. YES, I DID TURN OFF MY VSYNC IN GAME AND IN THE AMD CATALYST CONTROL CENTER. Anyways, our hardware is identical in every way, except for our CPU and RAM. He has an AMD A6-5600K (3.8GHz Quad Core), and I have an AMD Phenom II 810 (3.2GHz Quad Core). Also, I have 24GB of RAM, he only has 8GB. What I do not entirely understand is why he managed to gain such a performance boost, but I barely changed (I was still at the same FPS range). I feel like my CPU is limiting me, even though it is only three years old. For sure, I know it isn't my graphics card. Is it time for me to upgrade my CPU? Is that what's lagging my computer with Minecraft, and the reason why I can't get above 100 FPS? Is there something else that I need to do?

You don't need more than 60. It's all your monitor can display.

Actually, it isn't. FPS matters to me, I want to know what my computer is capable of. I also play on my TV, and it's 120Hertz (my computer outputs at 120Hz, according to the AMD Catalyst Control Center. 120FPS is at least what I want to achieve. How come I can't get as high as my friend? Is it the CPU?

Hi there. Sorry for your troubles.

I'm not sure how much further you can go diagnosing the problem
1) Have you tried fullscreen mode? It will probably yield better performance.
2) Neither CPU seems to be of the best performance from the benchmarks I've just looked at. Your Phenom II may be the problem, but don't quote me.
3) Are you both using the same drivers?

If it's actually vSync problems, then make sure:
If you're using OptiFine, try without. It seems that it still pays attention to the vSync option in the options.txt, but doesn't actually give any way of toggling it.

If you're replying, please quote me.

I'll answer all of your questions:

1) Yes, I've tried Fullscreen mode. It does make a difference, though minor.
2) I'm thinking it is, because mine's a lot older (around 3 years). His is just barely a year old, and apparently there were some major optimizations over the past few years...
3) We are both on the latest driver revision.

I have tried with Optifine and without. Optifine tends to make it worse, actually. So I avoid it. I'm pretty sure that it isn't vSync because sometimes it will stay at around 70 or 80 FPS. But that's on a lucky day. I average at around 40 FPS, which does not seem right. I've also tried reinstalling Java, but that has done nothing of help.

I'm actually going to be upgrading to an 8-core processor relatively soon, so maybe that will solve the issue. I'm not really sure why mine's been slow though. Again, I've had this computer for a while, so maybe that's why.

Is there anything else that you could suggest doing? I'm stumped. I've never had this issue before, so I don't know where to go next.

1. Is his on fast graphics?
2. When you start a world use far render distance then switch to normal.( It may not actually make a difference but it seems to for me)

Hello chasingfire_hpps!

1) No, he is on Fancy graphics. Everything is to the highest quality possible.
2) I just tried that, it doesn't seem to work...

I actually did try that, and it didn't change anything. I even let it load all the chunks around me, and the FPS didn't increase.

You can allocate more RAM that may help. And for my number 2 I guess I was imagining it.

Hello all! The problem was my processor! I just upgraded to an AMD FX-8350 (Eight-Core 4.0GHz) and now I am over 300FPS! My computer is much more stable too! Thanks everybody for helping me out!

And yes, I was planning to upgrade it anyways for video editing, so no worries or waste of money / time!
