Extremely slow performance with Radeon HD 7870

Mar 8, 2013 3:05 PM

Tags: #performance #slow #cs6 #windows_8 #gpu_acceleration #radeon_7870

Hi,

 

I am using a number of Adobe programs on my new Windows 8 64 bit system, with 16 gigs of ram, an Intel Core i5 2.67ghz, and AMD Radeon HD 7870 2 gig. All the programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bit, which has extremely slow performance with Use Graphics Processor enabled in my preferences (which Photoshop selects by default). If I turn off Use Graphics Processor, the slow performance vanishes. If I change Drawing Mode to Basic, there might be a slightly detectable improvement over Normal and Advanced, but it's still horribly slow. The refresh rate seems to be just a few frames per second. Everything is slow: brushes, zooming, panning, everything.

 

I've tried changing the settings I've seen suggested elsewhere: I switched Cache levels to 2, history states to 10, and tile size to 128k. No effect. Photoshop is currently at the default of using 60% of available ram. Efficiency has remained at 100% throughout all my tests. Also, this slow performance has affected me from the moment I installed Photoshop; it didn't crop up after previous good performance. The problem exists regardless of the size or number of documents I have open. Performance is still terrible even when I create a 500 x 500 pixel blank new canvas and try a simple task like drawing with the brush.

 

Photoshop is fully up to date, and so are my graphics drivers (Catalyst version 13.1). Any help would be greatly appreciated; at the moment performance is so bad in Photoshop that it's unusable with graphics acceleration enabled. Thanks in advance for replying.

    Have you tried resetting Photoshop's preferences?

     

    Have you tried disabling all of your third party plugins?

     

    Have you tried the AMD 13.2 beta drivers (which fix a LOT of bugs)?

    Well, it seems tied to the video card - but I'm out of ideas.

    Do you have another video card you can plug in?  Don't know if this is a new card or not but could be defective or the driver just does not work with that model.

    Perhaps it would be prudent to create a very controlled environment to gauge whether you're seeing something quite different than what others are seeing.

     

    It's possible, for example, that you're trying to paint with a 5000 pixel soft brush on a 20000 x 20000 canvas or something, which is slow for everyone.

     

    For example, if I create a 10000 x 10000 pixel, 8 bits/channel RGB image (white), and paint on it with a Soft Round 1000 pixel brush at 0% hardness and 10% spacing, I can get a little ahead of the painting operation, but it's not bad.   I see the screen update with brush info about 5 times per second.

     

    How does what you're seeing compare with that?

     

    What video card did you have before you updated to your current one?  Did you do anything special to clear out any remnants of older drivers?

     

    -Noel

    Wow, that's not just bad, it's horrendously bad!  You clearly have a major problem there, though I can't think what it could be...  Even a computer from the last millenium could paint on a 504 x 360 pixel image with a 13 pixel brush in real time.

     

    Do you see any improvement whatsoever if you disable the [  ] Use Graphics Processor setting entirely (then restart Photoshop)?

     

    I wonder if somehow there could be a component in the GPU that's bad and that only Photoshop is trying to exercise.

     

    I might try removing Photoshop entirely and reinstalling it, though I don't think there's any justification for doing that.

    Just wondering in the OP about the GPU, a clip from it"

     

    Video Card Caption: AMD Radeon HD 7800 Series

    Video Card Memory: 2048 MB

    Video Card Number: 1

    Video Card: Microsoft Basic Render Driver

    Driver Version: 9.12.0.0

    Driver Date: 20121219000000.000000-000

    Video Card Driver:

    Video Mode:

    Video Card Caption: Microsoft Basic Render Driver

    Video Card Memory: 0 MB

     

    It is curious that it does not recognize the model number, just the series.  Beleive it should say HD 7870 rather than  7800 series.  It also does not list video card driver.  The Micorsoft Basic Render Driver is listed, but I have seen this before in other users printout, but forgot what it means, perhaps that ATI driver has crashed.  Don't see that on my list.

     

    Bring this up as maybe someone smarter in computer stuff (like Noel) might get a clue as to what is going on.

    I know that my system info lists the ATI card by the correct model 5450.  Could not quickly find any other posts that list Sys. Info. but believe they list model of GPU.

     

    Not sure but the 0 mb for video card memory may be related to the MS Basic Render Driver.  It has the correct 2048mb for your card, but does not list a driver number.

     

    Here isa portion of my system info screen for a comparison.

    The "7800 Series" nomenclature seems right.  Here's what my system shows, in Windows 7 with Catalyst 12.8:

    I'm running Catalyst 12.8 drivers at the moment, and have a Windows 7 system, and have a remote access utility called Radmin installed, but I don't know whether seeing that Microsoft Basic Render Driver is expected on Windows 8.  It sounds like this could be the key, as Microsoft's basic OpenGL implementation is done all in software.  If somehow Microsoft's driver has taken over control and you're not really getting GPU acceleration, then that surely would make things really slow.

     

    Rafaello, you've updated drivers...  Can you post your top section of your system info again?

     

    Have you tried a full, complete ATI driver removal then reinstall from e.g., 13.2 beta?  Here's the ATI removal tool:

    That's good news, and I'm happy you've got an improvement in performance though that remaining lag you mention still troubles me some.  I don't see any lag at anything less than gargantuan brush sizes, and it's certainly no more responsive with the GPU turned off (my card is a 7850, not far from what you've got).

     

    If you'd like to try to nail down even the remaining lag, can you be more specific about just how you're seeing it, and guess at how much it is?  Describe which brush, what size/depth of document, etc. as you did before.

     

    -Noel

     

     

    P.S., I think the ATI driver installers (and uninstallers) aren't as good as they could be, which is why AMD published a separate tool for cleaning up.

    FYI, with a 15 px cursor on a 500x500px document, and painting quickly  I can see the cursor get a little ahead of the line drawn, but it keeps up and makes smooth strokes, keeping up with my movements no matter how fast I squiggle around.  I didn't even notice it before because I hadn't looked for it.

    I use IrfanView to capture my screenshots.

     

    It sounds like everything's working as it should be for you now.  That's indeed good news!

    You're welcome.  As one who uses a similar video card to yours, and who loves it, I knew it could work and work well, so while that was a late suggestion I did have some idea it might work.

    raffaellotiberius ans Noel ,

     

    I'm having some issues with the same series.  Should I do the same steps above?  The 7890 is advertised, to use GPU.  As we can see, GPU not available.

    In edit/preferences/performance is the "use graphics processor" grayed out?

    Wow, thanks for following up with that info.  I had no idea that tool could damage a user account on Win 8.  I'll be sure and warn folks in the future.

    Hi guys I have a questions, I use illustrator and photoshop and i am going to start learning after effects. I have been looking for a graphic card for a while and i would like to know if this one has a good performance with the video editing.

     

    I was comparing

    AMD Radeon HD 7870 Core Edition - 2048MB GDDR5
    vs
    NVIDIA GeForce GT 640M


    I understood that the Radeon HD7870 is much more better, but i would like someone who already use it and can confirm it!!

     

    I really appreciate any suggestion!!
    Thanks and regards!
