    Default Need help with insane lag and dark renders

    Registered forum members do not see this ad.

    I'm on the same system since 2012(no need to upgrade since it runs most things fine), 8mb ram, i7 2600, ssd, HD6950 and ACAD 2013.

    Even on a laptop, basic 3d renders (nothing complicated, just a rectangular house, no furniture), everything chugs along fine.

    Now that i changed to an R9 290, omg it lags to high hell at every single action. If i turn on the Sun status, it lags for 30secs. If i turn on Full Shadows, all hell beaks loose.

    edit: Turned off Shadows and it was better, Shaded with Edges still gave some lag while Shaded is smooth as silk. I give up trying to fix it, i can live with this.

    Do you have the latest drivers? If the problem started when you changed graphics cards, you need to start looking there.

    I have moved your thread to the AutoCAD 3D Modelling & Rendering Forum, please post your questions in the most appropriate forum.
