Is anyone else seeing this? I'm rendering the octane_benchmark scene and even after 4500 samples/px the aliasing on the edges of the cement blocks is REALLY jaggy. I'm running RC1 Win64 with a GTX 480.

Thanks radiance!

I followed your suggestions at the link, and after setting TdrLevel to 0, was able to do a nice 4K render, despeckle and downsample in Photoshop, and the resulting image looks fantastic after only 5 minutes of rendering.

Thanks!!!
