[Guide] [NVIDIA] Enabling vsync for Minecraft

Intro
When you launch Minecraft does your Nvidia card rev up? Silly card, it's only Minecraft that you're playing -- so why exactly does it rev up?

Because you get insane FPS in Minecraft.

I get an average of 700 FPS and 950-1000 while sitting in the menu screen.

Solution: Turn vsync on for Minecraft!
Problem: It's not exactly clear on how to do this, a lot of people target Minecraft.exe or the jar file for Minecraft. This is incorrect.

So if you can't target the jar file or the Minecraft.exe file, what can you target? A file called "javaw.exe". The only possible "downside" to this method is that all of your java applications that run through javaw will have vsync enabled. To me this isn't a con, it's a pro. YMMV.

Steps

Requirements
- NVIDIA Control Panel

1. Open the NVIDIA Control Panel by right-clicking your desktop and clicking on "NVIDIA Control Panel"

2.
On the left go to "Manage 3D Settings"

There will be 2 tabs now on the right. Click the one that says "Program Settings"

3.
Click the button that says "Add"

You will be presented with a file dialog box, we have to find your Java installation directory.

This will be something like:

Java 7

- C:/Program Files/Java/jre7/bin/
or
- C:/Program Files (x86)/Java/jre7/bin/

Java 6

- C:/Program Files/Java/jre6/bin/
or
- C:/Program Files (x86)/Java/jre6/bin/

4.
Once you've found the directory you want to add the file called "javaw.exe"

NOT: javaws, java, javacpl, etc.

Click Open once javaw.exe is selected.

5.
Under "Specify the settings for this program" we want to turn vsync and triple buffering (optional) on.

These two items are located at the bottom of the list, so scroll all the way down.

Triple Buffering: On
Vertical sync: Force on

6.
We're now done, click Apply at the bottom of the screen and close the control panel.

If done properly you should now see that you're FPS in Minecraft is affected by vsync.

To see your FPS you can either use third party software such as Fraps
OR
Login to a Minecraft server and hit F3, your FPS information should be shown in the top left corner with some other information.

Enjoy!

If this is the wrong section to post this in please move it!

I only posted this because I've seen a few people complain about hot temps while playing and couldn't figure out a solution

Not sure why you would lag, that's probably a SLI or driver problem

That seems to be a common problem which, unfortunately, I can't test (I don't have an SLI configuration).

I wish I could offer help

This should work as long as you add the correct file. Have you tried adding the file from System32 that it's using?

Make sure that you apply the settings then close and re open Minecraft to ensure that the new settings are being used.

I don't recall ever having Java 6/7 installed into System32, are you sure you're using the latest version? Try downloading Java 7 and applying this fix to the jre7/bin/javaw.exe file. Also, check out your batch file and see if it's using "java" or "javaw" to launch MC -- if it's using "java" try changing it to "javaw". From my knowledge it shouldn't be using "java" as Minecraft isn't a console application..

If that fails you can always force it to use the javaw.exe from the batch file like this:

(edit this and change jre7 to jre6 if you're still using 6)

Should do the trick then if you add

"C:/Program Files/java/jre6/bin/javaw.exe"

To the NVIDIA Control Panel

(assuming that's your path)
