Nividia Compute Visual Profiler options grayed out

When I analyze a kernel of mine, following buttons are grayed out in the Kernel Level Analysis:

• Limiting Factor Identification,开发者_开发技巧
• Memory Throughput Analysis and
• Instruction Throughput Analysis.

... while Occupancy Analysis is activated.

Is this behavior due to my old gpu (Quadro FX 580 with CC 1.1.) or due to me having set the wrong checkboxes?

It could be due to either -- older GPUs don't have the same built-in counters, which means that the data can't be collected from them. I normally check all the boxes for a specific run, then see what I get. I uncheck boxes as necessary for further tests.
