Hi everyone, this is first time that I am posting on this forum, and I hope that I will get help. I am using Civil 3D 2014, and a couple days ago I changed my ATI HD 4850 with Nvidia GTX 570 2.5GB. And I did not noticed any improvement with new card! My road is about 5 km long, I have about 3000 points, surface, alignment and corridor are in different dwg files and are connected through Data Shortcuts. And I still have problem with viewing corridor in 3D orbit, even in 2D Wireframe everything is so slow, almost as when I had old 4850. Grip edit in alignment is simply impossible, superelevation edit is slow as it was before upgrade. I was hoped that I will get a better performance with GTX 570, since it is powerful card, but now I am very disappointed. So I am interested does any of you had experience with this GPU, did had similar problems with slow workflow of civil 3d, or problem is maybe in some other component. My cpu is Phenom II X4 960T, RAM 4GB 1800MHz DDR3 (it never goes over 60-70 % load), SATA HDD. I will be glad if someone could help me with proper advice, since I will not be happy if I should change my GPU again!
