Hey everyone, since 1.3 cam out I've been having severe FPS issues. The most that Minecraft will ever give me is 30FPS, no matter what I try. No matter the graphics settings, or mods installed, I only get 30FPS. I've even tried with and without optifine. Now, I know it's not my computer, since before 1.3 I would play on about 800FPS. Any help would be greatly appreciated, thanks.

For what it counts, here are my specs:

Processor: Intel 3960x i7 (Liquid Cooled)
Graphics Card: Radeon 7970 x2 (Crossfire)
Boot Drive: 240GB Intel SSD
Storage Drive: WD Velociraptor 1TB
RAM: G-Skill Ripjaws 16GB (8 Allocated to Minecraft)

If there is anything else that'd help, I'd be happy to let you know.

Is the FPS thing in the options at Max FPS? Thats all that I could possibly think of. It could be at balanced or something, which is what would cause it to drop.

I do have it on Max FPS.

I think the issue has something to do with Minecraft attempting to match the chunk updates to the FPS. It appears that the chunk updates and FPS are almost always the same. So if there are 27 chunk updates, I've only got 27FPS.

No help? The game is basically unplayable in this state..

I have no idea about this but I'd suggest you download Java 7 x64 and x86. See if it has any effect.

Edit: I forgot to post download link. http://www.oracle.co...ds-1836441.html

Thanks for the help, but I've already tried it, but to no avail. :/

Hmmm... did this start happening when you installed optifine? Because this is exactly what happened when I installed it on my gaming rig, my fps somehow decreased instead of increasing.

It happens both with and without it.

Install Optifine Ultra. I've a crappy old computer and with Optifine Ultra I've 80-100 FPS with 64x Texture Pack. That would solve your probelm.

I do have ultra installed.

Has your computer been running slow recently? If so you may have a virus.

Another thing I can think of is if you have the latest Java update installed.

Another thing (more simple and stupid) is to force update your Minecraft, if you don't know how, boot up MC, and on the Log In screen, above the Login button there is an Options button, click that and you will see a pop-up window with the option to "Force Update", click that button and close the pop-up window, and log in.

YET another thing is to completely wipe your MC files, by typing %appdata% (WITH the % signs) in your Run or Search bar in the Start Menu. A window should pop up and one of the top folders should be .minecraft. Delete this folder (if you do not want to lose your Singleplayer worlds go into .minecraft and find the saves folder, and copy your world(s) to a different location.) and Force Update like I previously said.

This is a long response but hopefully this will help fix the problem!

Thanks for the help, but I've literally tried all of the above. This is a really odd bug, and I really have no clue what's going on. I can play other games on the highest setting possible, and get 150+ fps.

So it's been a few days, and I still have no clue what's wrong. Still no help?

Have you updated drivers recently?

Yes, every time Catalyst reminds me to update the card.

I am having the same issue. Also when i place a block it puts another one down real quick. I can't play like this I might smash my computer.

I think our problems might be somewhat different. What are your specs?

Processor: Intel Core 2 Quad 2.66GHz
Graphics Card: Nvidia GTX 260 x2 (SLI)
HDD: 500 GB x2
RAM: 8 GB

The 260's are older cards, and Minecraft doesn't benefit from SLI or Crossfire, but with those cards you shouldn't have any fps issues at all.

Minecraft is a 16 pixel game it doesn't need a 7970 in crossfire, nor does it need such a powerful CPU. When you open minecraft it may be switching to your integrated graphics as minecraft doesn't need that much power. You could try checking if that is the problem.

Well, my motherboard doesn't even support on-board graphics so that's basically impossible.

After a little playing around, I think I've found the problem. I think it's the gpu settings, something about it is wanting to default to 60fps in everything, basically. Anyone have any idea why AMD Catalyst would want to default to vsync?

Same problems. Variable fps after ver 1.3. Frame rate comes to a screeching halt for a few seconds. Often.
No background programs. No virus.

Win7 Home x64.
ATi HD7770.
Asus P5N-D MB.
Core 2 Duo 3.4Ghz.
8Gig Dual Channel ram.
SATA standard spindle type drives.

MB drivers, video drivers all uninstalled/reinstalled.
Minecraft files removed and reinstalled.
No texture patch. Vanilla.

Extremely frustrated.

Because it's better on your energy bills. Most monitors will not even display faster than 60FPS, so some cards automatically set to VSync to save on energy usage for your Video Card.

I know for a fact that I've got a 120 Hertz monitor, so I'd really like to see Minecraft getting at least that, and if it is the card that's causing the vsync, why did it just start doing it now?
