Cannot disable the GPU acceleration

I tried the GPU acceleration in the past, but it has not been activated for my Radeon HD 6950. Ironically, today, I found it was and he lit. LR soon froze in the develop module, so I went into preferences to turn it off again. I tried several times, but it is not clear, everything freezes! I tried to restart, but crashes again on the attempt. Is the only way to delete the preferences file, and if so, where is it?

Hi Bongboots,

Please follow the Solution below

  1. Go to edit > preference > Performance > uncheck "processor chart use" If this does not solves the problem then,
  2. With Lightroom closed
  • Access

C:\Users\YourUserName\AppData\Roaming\Adobe\Lightroom\Preferences    (Where AppData is a system folder / hidden so you may need to enter the name of the folder directly into your browser's address bar or activate hidden folders / system in the Internet Explorer view folder options.)

  • Open the file LightroomPreferences.agprefs
  • Locate the line use = True autobahn (press CTRL + F)
  • Take Autobahn use = False


After save the file

Restart Lightroom

3. also refer to that link and update GPU if you use AMD map

  • SpeedGrade CC2014.2 disables the GPU acceleration

    As said elsewhere, but this time in a PC, SpeedGrade's latest incarnation (CC 2014.2) GPU stops and gives the "lack of GPU resources' dialog box when according to GPUZ he only used 2 to 6% (Yes, it is two to six percent) of my GPU and 600 MB of the 4 GB of vRAM, I've got. No other program other than the operating system running... Manager tasks indicates less than 50% of the CPU to work, only about 6-8 GB of my 16 GB of RAM in use (Adobe apps together for up to 12 GB). So it's not as my system resources are in tatters, is it?

    OS/programs on an SSD RAID 0 pair; files images and project on 2 TB internal of separate units, all on a flash SSD disk cache stuff in-house.

    Data sheet:

    So far, but NONE of the Adobe apps used more than 25% of my GPU and always used 1 GB of video memory, it's ridiculous... sigh.

    work to normal for me now. My first project sequences are 720 x 480-9 of them, one being the 1920 x 1080 as shown above.

    I went back to first and reduced my sequence settings to match everything else. Why 720 x 480 is I do always 1920 x 1080 and this stage of a project is limited to SD, so I match all other media. I had ignored cutting a sequence so far.

    I don't know if it was my dose, but Speedgrade working and leave my GPU in action now.

  • Performance is worse with the GPU acceleration that without

    I have a Windows 7 system fast, i7 980 X processor with a monitor @ 2560 x 1440 pixels. As a photographer, I'm processing of thousands of photos and my PC can not be fast enough, so I thought that I invest a little in a new graphics card. OK, I have not bought a Quadro, but with GTX 970 from Nvidia, I always feel a modern, fast, with a value of more than $ 400 map.

    My first experiences after the installation of the new graphics card are more then disappointing - a lot is worse, running without any GPU acceleration. Before, I could scroll an image to the image almost no imperceptible lag. With the GPU acceleration turned on, each image must be "rendered" first first you get a blurry picture of Pexelated / of complitely and flackers of color shortly, then after a while, it becomes more clear. So it seems that with GPU acceleration turned on, Lightroom 6 completely ignores the preview images pre-rendered - FACT IT MAKE any SENSE WHAT? Yes, all the sliders mode develop work faster, but the preview shown instantly image is a false low resolution and it always takes time for an image high resolution to display - as much time, as it should, making it with a CPU.

    For me, it would make sense that next image will be loaded into GPU memory by actually DURATION and rendering the previous image would be preserved in memory as well. Also miss me some detail for the GPU acceleration settings - if it remains at the current level, rudimentary, (for me) the best compromise would be to disable the GPU acceleration to scroll through the photos, but using just to develop sliders.

    I would want guus at Adobe to improve the product real, not just marketing slogans on the improvement of performance!

    . My suggestion is simple enough - if the guys at Adobe can not program properly, the easiest would be (to make an option) to disable the GPU acceleration for image swithiching and just take his profit for the developer sliders.

    You can not simply switch off to change the image. The image * should be loaded into the GPU, which is where the delay comes from. Even though you might think about what would happen: of course the image would change quickly, but then you would still wait before you can deal with.

    For now the acceleration GPU in LR is very it is childhood: things first generation, and we are all good enough beta testers.

    Some people are lucky: they love him and have no problem.

    Some people are out of luck: it causes nothing but problems.

    Some people like me are sitting on the fence: we have mixed experiences.

    I don't think you threw $400, at some point (I live in optimism) questions will be fixed and LR will work on your system. He just had to wait. Isn't is funny, but you only need to take a casual look at any photography forum to see that there are problems with GPU acceleration and now is not the time to buy the latest and greatest card.

    I've personally held off buying a new card to replace my aging one until I see that there is zero chance of all the problems of proof.

  • LR CC 2015.3 version still crashes when the GPU acceleration is used!

    Today, I had installed Version 2015.3 and was hopeful that all the bugs have been fixed and all the problems of recent months have disappeared.

    Wishful thinking? When I turn on the GPU acceleration, it freezes again! When I disable it, everything seems to work well.

    I use a series of 380 MSI AMD Radeon R9 with 4 GB of GDDR5 memory on a Windows 7 computer.

    There is other users with similar experiences?

  • Lighroom 6.1 develop vs vs library export colors change with the GPU acceleration

    Having managed to obtain the execution of acceleration GPU (with AMD Radeon 6800 on Windows 7) subsequently, I make a radical change in color between the library and develop modules.  The develop module shows a really cool picture.  This can be 'activated' on and outside by disabling GPU acceleration.  The library files and anyexported show a warmer image in comparison.

    How can I fix it?  Anyone has any ideas - I had to disable the GPU at the moment... again...

    Library and develop are color management and use the profile.  But they use it in different ways with different code (for example develop uses the GPU is not the case of library), so incompatibilities in the risk profile of stumbling one but not the other.

  • The GPU acceleration is grayed out in first and AE, but not in Media Encoder. However, the rendering is slow in all 3 programs.

    It worked fine in CS6.

    Now, whenever I open a project (Pr or Ae) I get the message: this project has been modified used with accelerated by GPU rendering. This happens with all projects, even with those that I created in the Pr/Ae CC, with already disabled accelerated by GPU rendering.

    In Media Encoder, the GPU acceleration is not grayed out, but still if I made a first sequence or model ae via ME, its very very slow. (takes 5 hours for a video that took 20 minutes in CS6)

    Any thoughts?

    Thank you, Daniel

    I didn't have the time to post it yesterday, but you have found similar work around. What is happening is the decoding of earlier projects, or projects of the same version even sometimes won't boot the MPE of hardware engine. These files are cached and won't clear for this sequence until you delete the cache. 1 way to do is to replace the clips. The easiest is in the future change the EMT of the material to the MPE software and select delete the files from the cache when it invites. Then return to the MPE material and clear the cache again. That recreates the decoded files cache that often solves this problem.

  • Is it possible to disable the GPU dedicated Satellite L850

    Is it possible to disable the GPU dedicated on the L850.
    Through the BIOS or something else, so that the laptop works on the onboard graphics on the CPU.

    Thank you

    Hello

    What L850-xxx you exactly and what dedicated GPU support?

    Laptops that support technology Optimus (with nVidia GPU) could switch automatically between the GPU (Intel) internal and external nVidia GPU and it depends on the application running.

    In some cases, you might choose weather, that an application must use internal GPU Intel or NVidia GPU.

  • Black screen (no output) for RED files on the GPU acceleration

    Hey, maybe you can help me with my problem, since the update, I can't use the gpu acceleration for rendering of the r3d files, anything r3d in my calendar has become black, if I do not pass the software, I had hoped maybe I could export with gpu but it fails just there as well. From what IV ' e reading the question is if you have a gpu that is obsolete, but I have a gtx 970 if im not sure what I could do, resettlement had no effect.

    the software only reads it in real-time to the ground full...

    I guess that's a multiple GPU issue?

  • Application cannot recognize the hardware acceleration, but it certainly is turned

    Hello

    I'm a newbie on this forum, but I have looked around before posting my problem and could not find any solution. Maybe there is someone who can give me a hint.

    Here's my problem: I have two users on my desktop pc Windows 7, two users play Farmville 2. Until the update of last week everything worked well. But now Farmville displays a message saying that hardware acceleration is turned off and the mode full screen option is not available. This applies to user 1 on firefox and chrome and user 2 on chrome only. In other words: User 2 can play in full screen mode with firefox but not with chrome.

    I checked everything that mentioned on the Flash Player help page games, video or audio does not work. Windows. (The Flash Player Information bos said that my OS is Windows 7 (32 bit), although I certainly have a 64 bit OS). I removed the Flash player and re-installed and activated the hardware acceleration, which is needed to play Farmville 2 in full screen mode.

    Thanks for any help

    Werner

    We actually install a Player Flash 32 and 64 bits in parallel on your machine, but one that is used depends on the number of bits in the browser host process.  Firefox is a 32-bit browser, so you're going to get Flash Player 32-bit.  I don't really know why the Flash Player entry in Control Panel includes (32-bit) in the name.  It was probably logical at the time, but that's another question entirely.  Google Chrome is a different beast and the latest versions of Chrome on Windows are 64-bit, and they include the Flash Player 64 - bit corresponding PPAPI.

    In any case, I think here is if you have enabled hardware acceleration, but if hardware acceleration is not available, we probably have to index your GPU drivers because they are unstable.  The fact that happens in Chrome and Firefox in favor of the theory.  Update to the latest graphics drivers available, generally will do.

    I * am * a little perplexed about why he works for a firefox user and not the other.  Firefox * fact * have a way of browser globally disable hardware acceleration.  I wonder if the affected user has this option enabled.  It's under Advanced > General > use hardware acceleration when available.  I'd be curious to know if it happens again with a fresh Firefox profile: use the Profile Manager to create and delete profiles Firefox | Firefox help
