CS4: Image blurry at arbitrary zoom levels - Adobe Photoshop

This is a discussion on CS4: Image blurry at arbitrary zoom levels - Adobe Photoshop ; Running Vista-64, OpenGL features enabled (and working). Nvidia 260gtx card with newest drivers (178.24) Image is rendered sharp at the predefined zoom levels (like 25%/33%/50%/66%). Then if I zoom to eg 55% the image gets blurry. Any ideas ?...

CS4: Image blurry at arbitrary zoom levels

  1. Default CS4: Image blurry at arbitrary zoom levels

    Running Vista-64, OpenGL features enabled (and working).
    Nvidia 260gtx card with newest drivers (178.24)

    Image is rendered sharp at the predefined zoom levels (like 25%/33%/50%/66%).
    Then if I zoom to eg 55% the image gets blurry.

    Any ideas ?

    Photoshop has done this for years. This is nothing new.

    Same problem with me. I've updated drivers and I have the same issue. Pics just dont look sharp with OpenGL.

    I have to say that just like a lot of other users, I'm really disappointed with CS4's performance - its really slow compared to CS3.

    No issues here. So once more I can only blame that on the config of your card exposing some oddities or the cards themselves being to new to have been checked out more thoroughly.

    Can`t Adobe just tell us, how we should set up the preferences of our nvidia cards?

    Well, Adobe doesn't know your hardware, don't they? ;-) Sorry, this is too much to hope for. From simple things like font sizes to themes to color profiles to screen resolutions there is too much that can affect performance, especially with accelerated functions. I know that some of you are grinding their teeth, but no matter how little you may like it, only trial&error will get you there. In general it is advisable to start with a clean slate and take it from there, meaning to reset all driver settings to their defaults. On my systems that approach always worked and I never had to spend long trying to figure things out. Just have patience...

    My setup is as you describe; Driver settings is at default.

    I have tried two different (nvidia) cards. The latest one (gtx260) is on the list of tested cards : <http://kb.adobe.com/selfservice/viewContent.do?externalId=kb405711&sliceId=1>

    I just wonder how many people must have these kind of problems when you consider that my system is very ordinary.

    Mylenium,
    probably you`re right, but aren`t the settings that are available the same at least within one series (for example Geforce 8 series cards etc.)?
    I`m talking about fundamental settings like "anisotrop filtering",
    "antialiasing-mode", "triple-buffering", "force mipmaps" etc. etc.
    To a non-gamer like me those settings are "unknown" and strange. But I could imagine, that there should some recommendations at least for some important fundamental settings. Am I wrong?

    Mylenium sorry but...

    am cs4 trial user and 4 of my friends too. for example my system amd 6400+ and a gtx 260 and 4 gig of ram an vista x64 sp1. the systems of my friends: xp32 sp3 2 gig ram and a 7950 gx2 , xp32 sp2 2 gig ram and ati 4850 and the last vista32 sp3 gtx380 and 3 gig ram and we ALL do have that strange issue. if we zoom out the pictues gets VERY unsharp - if we zoom in they are sharp....for example..if we zoom out and the picture is unsharp..we klick the window and undock it...the picture becomes sharp...if we leave the mouse button it gets unsharp again...as if a unsharp mask filter renders the windwos...its UGLY...i think i get eye cancer.we tried everything...drivers...old ones..new ones...motherboard drivers...anti antialising settings mapping texturing..everything..NOTHING....i do a LOT of people photography and landscape..with this problems it is not possible for me to zoom out and look at the whole picture and decide if it is good or not..my eyes are beginning to burn after 10 minutes of work and i work on 2 eizos 19". if i turn of opengl this issue is no more but cs4 is verry laggy then and slow...even if i adjust cache and memory settings. when i activate open gl and go to advanced settings and uncheck averything this issue is still happening....VERY unsharp.

    so now..my trial is running and cs4 is a disaster so far to me. if this will not be corrected soon or no one can help me i thing i will keep cs3 till cs5 will come.

    please help us!

    I've found that CS4 is also much slower at rendering picture packages.
    P4 3 GHz, SATA HDs with dedicated scratch drive, XP32, NVIDIA 8600GT, 2GB RAM --- Photoshop 6.0 was lightning fast compared to CS4!
