Things slowing down - not able to choose OpenGL in SP0

Discussion in 'SolidWorks' started by David Hampson, Jan 30, 2004.

  1. Hi all,
    I've just installed 2004 SP0 on my machine at home, Athlon 2400 with
    the nForce2 chipset running the onboard graphics, to do a bit of weekend
    work and have run into a problem. The install went fine, I loaded up a part
    and as time went by I noticed things, rotating, zooming in/out, slowing
    down to a crawl. I decided to check to see if I had accdently checked the
    Software OpenGL option but when I went to the appropriate tab in the option
    dialogue, I found the Software OpenGL option greyed out. I would assume
    from this that I am running in Software OpenGL and for some reason the
    session can't find hardware OpenGL. I closed the part, closed SW, rebooted
    the machine and in the process of doing this increased the memory for the
    onboard graphics to 64MB and then restarted SW. Before I loaded a part, I
    checked Tools->Options->Performance and the option is there, not greyed out
    to choose Software OpenGL - but I didn't, it was unchecked. I then loaded
    the part and checked the Software OpenGL option again - it's now greyed
    out. Has anyone else come across this problem and have a fix?

    I'm running this on Win2000 with the latest, V3.13, nForce drivers
    and that's about all, nothing special. Any thoughts, comments greatly
    appreciated.

    Regards,
    David

    It's always greyed out as long as a part or assy is loaded

  3. If that's the case, then any other ideas on what's causing the slowdown? It
    looks like it is the same problem that a Google for

    solidworks "slow down"

    reveals :( Funny thing is that at work, which is a roughly the same speed
    machine, same ram but with a 3DLabs card and running XP, this does not
    happen - home machine, on board graphics, Win 2000 and it does happen...
    Probably a combo of graphics drivers and OS. Thanks for the answer anyway

    David

    Sorry to say....beats me....I was warned on an early stage for the Force
    cards so I went straight for Quadro and has been there since that. Guess
    this problem is related to the card and/or the driver.

    The issue you are seeing is common to all 'consumer' level graphics
    cards such as the GeForce and Radeon (nForce video is really just
    integrated GeForce). These cards are targeted toward the gamer.

    The 'professional' level cards like Quadro, FireGL, and WildCat do not
    suffer from these issues. These cards are targeted toward high end
    graphics applications like CAD.

    The Geforce2 chipset can be upgraded to the Quadro 2 chipset by using
    Softquadro, works great for me on my home computer. The card chips are
    identical but NVidia progressively crippled them to attract different price
    range markets with 'different' cards.

    I had the same thing happen to me. I'm using a Quadro4 900 XGL video
    card and had no problems up until SW2004. My problem occured when I
    added a second monitor. After fiddling around with with display
    settings I got SW to run without the Software Open GL.
