graphics card issues?

I've just bought a new PC, mainly for rendering, but also some modelling (nvidia 6800 graphics card). I'm having a few problems with the screen display of Solidworks. When I do a render on screen the outlines/colours are jagged and when dimensioning in a sketch the dimension values look ragged. I'm assuming that this is a graphics card issue. Has anyone else had these kinds of problems with this card? Could you let me know of any features that you disabled or did you try forceware form guru3d.com?

Thanks.

hey ho will, Could be the new card is faulty - bad luck but maybe you can return it- or just not seated properly in the slot. Do you have any problems in other applications or just SW? sounds like something to do with zbuffer utilisation... BTW which version and sp of SW are you using?and which nvidia driver?sometimes there are issues within SW itself or with a particular driver. I presume you are using PW for rendering... Do you realise you can use a bit of software called 'rivatuner' for the 6800 AGP versions to identify them as a quadro FX4000 and it will run quadro drivers and function as a FX complete with 'unified back buffer' ?- maybe your issue I started using a 6800GS recently in this way when my old Quadro750 died a lingering death and it seems ok. You will find info about the mod under the rivatuner forum at guru. I really recommend you use a Quadro card for SW instead of one intended for gaming though because they are optimised for CAD purposes and so are the Quadro drivers... and further more SW work in with nvidia for development purposes and test and certify particular drivers as suitable for SW use. Possibly you should return the card and get even something like a FX 500 or

540 and it would be more assured of working properly with SW. HTH

BTW you do have anti aliasing turned on for your renders? without that you will get staircasing of outlines in renders. ...and you are not using the 3d option in SW for showing dimensions which gives them a ragged fuzzy appearance?..

Hi,

Thanks for the 3D sketch option point... that was causing me a few problems. The driver version is the Nvidia 7.7.7.4. (if thats the info you require). I have changed a few dimension settings and monitor display settings and the display seems slightly better. I might try the rivatuner software though if it gives me any more problems.

cheers.

ok pleased things improved. In future - it pays to give details of your set up when asking questions because sometimes there are known issues with a SW sp or driver. You might try changing the nvidia driver to a later one if you think there are specific problems with the display for SW. Guru will give you feedback as to which ones work best with gaming - not necessarily an indicator for SW though.Generally it is better to go for the official ones on the nvidia site. If you try rivatuner be sure to read thoroughly about it at the guru forum first. HTH
