Another Laggy Minecraft Issue

[Toasted Baby]

Ok, so I'm sure you're all tired of hearing this, but DxTory causes my Minecraft to lag only while recording.  I've tried rolling back drivers, changing codecs, changing resolutions, and nothing is helping.    I record at 100% resolution, 30fps using the Lagarith codec (tried RGB, YUY2, and YV12) to a separate 2TB hard drive rated at 113MB/s write speed.  Normally, I get about 100-200 fps while playing, but right when I start recording it drops down to about 26fps play/26fps recording.  I can't tell you when this started, because I've had DxTory for about two years, and it and Minecraft never really got along.  If there was a problem, then I would switch to Fraps for a while, and then come back to DxTory and all would be fixed somehow.  But DxTory has been this way for about 3 months, and the magic Fraps swap has failed me this time around.  Again, this is the only game this happens in.  All other games I play are recorded without any issue.  Computer specs are as follows:

i7-4770k @3.5ghz
2x GTX 770 4GB in SLI
16gigs G.Skill Ripjaw RAM 1600mhz
Samsung EVO 250gb boot drive (Minecraft is launched from here)
Hitachi 2TB recording drive (where I record DxTory to)
1920x1080 monitor

I am currently using the 340.43 driver, and I rolled it back to the 338.88 or whatever the previous version was.  That didn't help as it has seemed to for others.  If you need anymore information, please feel free to ask.  I'm starting to miss my multiple audio tracks.

Is a setting of Minecraft the cause?
I confirmed that it works normally.

I've tried changing all of the video settings in Minecraft, and they all result in the same recording lag.

does it happen with default texture pack? are you using mods? disabled vsync? how high is your fps limit (performance: 10-unlimited fps)

[RobiePAX]

I don't understand why people go "unlimited fps" on Minecraft. What's the point of pushing the crap out of CPU/GPU to render 600+ frames per second. 120 fps should be the max fps cap.

does it happen with default texture pack? are you using mods? disabled vsync? how high is your fps limit (performance: 10-unlimited fps)

Yes, with default all the way up to 256x256.  No mods except for Optifine and Shaders on a 1.7.5 versions, and nothing on all of the recent snapshots and another untouched 1.7.5 version.  Vsync is disabled, and I play with a 120fps limit.  I've tried changing the FPS limit, enabling and disabling vsync, changing all of the video options, etc.  I've also done a clean reinstall of DxTory, and backdating to every version between the .118 release to the current .127.  Same issue with all of them.

[Toasted Baby]

I've updated to the new 340.52 drivers, and the issue still persists.  Could the problem be Windows 8.1 based?  I never had this issue when I was using Windows 7, but it also didn't start until about 3 months after I went to Windows 8.

You are giving odd numbers to your AMD Drivers version. Latest AMD stable drivers are 14.4 . You should find and install any 13.X version drivers.

If you have the Synchronize Video FPS option checked in DxTory, uncheck that option and see if that fixes it.

AMD drivers on Nvidia system?

Anyway, Minecraft & it's opengl implementation have usually been a bit unoptimal, I've had harsh drops of fps when I recorded it as well.
Have you tried disabling sli for the game? Or try the "Enable Multi GPU Fix-code".
Also try increasing dxtory processing threads.
Also probably worth trying is to set minecraft to unlimited FPS, since it seems you limit FPS to 60 from DxTory anyway. 2 limiters might not interact well with eachother. Or leave MC to 120 and take the fps limiter off from dxtory.

edit: well derp, "LimitedFPS: False". I could actually TRY to read the env-info

Anyway, maybe still try unlimited in MC and limit the fps to 60 or 120 with dxtory?

Oh nevermind, I mixed up threads.

The Multi-GPU fix in DxTory seems to have fixed it, with SLI enabled and disabled.  I completely forgot about that option.  Whoops.  Anyway, its now recording normally now.  It's a bigger FPS drop than I get with Fraps, but it's still loads better than the 26/26fps I was getting before.  Thanks for all of your help!

EDIT: Fixed the FPS drop issue by switching to YV12 instead of RGB mode.  Slightly lower quality, but hey, it's Minecraft.  Again, thank you to everyone who helped.  This issue is now resolved.
