  • Update your ATI or nVidia WHQL video card drivers to the latest. This is very important.

  • I’m not sure if this file is actually updated. The file still has 1.4.6 in its name.

  • optifine d5 ultra doesn’t works with minecraft 1.5!
    optifine a2 ultra is for minecraft 1.5, is the GLSL shaders works with that?

  • WRONG! Does not work with 1.5.1, you’ll have to wait until it actually comes out 🙁

  • Not 1.5.1 compatible, only Optifine A7 Ultra works with 1.5.1 & GLSL Shaders only currently work with D5 ultra for 1.4.7 etc

  • dont work for me i dont see options> shaders in minercraft menu


  • Why do you say “1.5.1” in the title if it doesn’t works with this version ?!?!
    Do you think it’s a funny joke ? Or is it a ridiculous way to make traffic on this site ?
    I tried so many links for this mod or Sonic Ether’s one. They all claims working for 1.5 in the title, bu this is false !!!
    Why ?
    I understand that a mod could be long/hard to program, but it’s not a reason to write false things an make many people angry by trying without succes.

    • Hey, it’s isn’t for 1.5.1!

      See the file:
      “For OptiFine D5 Ultra:”
      ^ ^

      It’s only a way to make traffic on this site, but they will update in the future.

      Search the official topic of the mod:

  • This didnt work for me…. this better not be a troll or I will be VERY mad.

  • if You Guys keep telling Black screen your just so nooby and lazy because Black Screen Is META data thats Attacking your Minecraft you guys Need To remove All The META – Data or you will never get it work just don’t be so lazy k? Guys?

  • finaly i find a clear answer, i delete meta file and install apropriately, the optifine works just fine but once i add what you told me to add… i get black screen. and yes i double checked the meta folder is deleted! please remove 1.5.1 from your title….if there isnt a new mod for it

  • Ther IS a link for 1.5.1, minecraft forums topic, page 68, near the bottom.

    • But that is the beta version of the mod and not compatible with newest OptiFine. So in short, you’re going to have a lot of problems when you install it.

      I do not post unstable mods here.

  • well I can’t get this to work for 1.5.2
    the problem is they require D2U version of optifine
    however in optifine 1.5.2 the only D2 is D2L
    the others are D3S and D3U

    it would be nice if they could ‘link’ to the correct version
    and yes i’ve tried D3U incase the D2U was a typo, i even tried D3S


  • I installed it correcly but i got black screen when i start minecraft :I

    Please help.

  • I can’t find “shaders” in options for the life of me. Perhaps they tossed it in 1.6?

  • I don’t find Optifine D3U… Is it D2U? Because D3U doesn’t exist 🙁

  • Will you please update to 1.6?Me and so much more people would REALLY love it!

  • When is the release date for 1.6 version of the pack?

    I’m starting a new series and I need this mod ASAP!

  • Help I keep crashing and my minecraft 1.6.2 consul says something like no openGl = false or something like that HELP

    • more specific info: My GPU is not compatible with the shaders mod how do I fix

    • It isn’t lag you idiot. You have a shitty pc which is why you are experiencing FPS drop. Lag is when you experience events after other players on a multiplayer server because of a bad internet connection and it has nothing to do with FPS.

      • well server lag has nothing to do with fps, but when people have bad fps they commonly refer to it as “lag” which is obviously what he was saying. so he was right

  • Hey, I installed it all correctly, with optifine, and without the GLSL Shaders mod it works fine, but with it my minecraft crashes instantly. Anybody else experiencing this problem?

  • Hey. i have install’t shaders and optifine (forge) om my minecraft, but when i try to start it, it crash. I have a craft rapport, where should i put it.

  • When I open minecraft after i added shaders and then i go inta options it doesnt pop up

  • omg im using this site forever it works soo good i would give this site a GIGANTIC THUMBS UP

  • I love this mod so much because it makes my Minecraft looks more realistic, but can you update to 1.7.2/1.7.4 plz ?
