Computer built by myself for CAD: i4790k, Quadro K2000, 2x8gb 1866mhz ram, 480 GB SSD, z97x Mobo.

I figured this comp would crush CAD's and be a big upgarde from my Dell latop I had bought a year ealier for 1,000 bucks.

However when I try to rotate the heading in my 3d drawing it freezes for a rediculous amount of time up to a full minute, when it unfreezes only about 10% of the lines you should see are visible as you rotate until you release cursor. My laptop would lag for 5-10 seconds usually on the same CAD. A coworker loaded up my drawing on his Asus g75 laptop running a Nvidia 850m graphics card and it paused for about 2 seconds before rotating the whole drawings with all lines visible.

So how is a freakin 850m putting an ACAD certified K2000 card to shame? (Had similiar results with a GTX 960=not good orbit performance.)

Update: Using the Nvidai GPU resource monitor, when rotating the CAD drawing it is being completely unused while several of the cores on the CPU are being used upwards of 90%. Zooming in and out does utilize about 25% of the GPU however. CAD is still recognizing the k2000 card as certified and updated driver, and my on board graphics are disabled through the control panel.

Yes I do have the recommended driver, have also tried a later driver but went back to the certified one as it was slightly better. In smaller drawings I do not have this issue, the drawings rotate in real time very smoothly. I also have my on-board graphics disabled not sure if thats causing an issue.
