Need help with insane lag and dark renders

[neuri]

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.
