We can confirm the behaviour that 610 is seeing. We get about 2 fps on the DS display, but there is a delay on top of that. The frames update at 2fps, but the frames we see are also more than 1s in the past. We notice this poor performance in the Driver account, even with 160x120 resolution frames.

Strangely, increasing the resolution does not seem to slow the framerates on the DS. In some cases the DS display updated faster on 640x480 than on 160x120.

However, the rate in which the cRIO processed the image was considerably faster with the small resolution.
