I'm running the Unigine Valley benchmark extremely smoothly as long as the framerate stays in between 48-144fps. When it drops below that, I'm observing heavy stuttering and flickering in the darker parts of the image. The flickering also affects the loading screen when frames are rendered very infrequently.
