Your commit seems to work here on a newish NVidia system. The diagnostics are at OSG_NOTICE, which is the highest, correct? I get a spew of frame timestamp messages.
It looks like GL_QUERY_COUNTER_BITS_ARB is returning 0 on your system. I don't know what that means if GL_ARB_timer_query is supported. I'll google around a bit. An interesting problem in the stats graph shows up with the new timer. Actually, I've seen it before, but I assumed that the timer query would take care of it. Sometimes the GPU bar doesn't show up at all. I think that the GPU time is happening more than one frame after the corresponding draw traversal, which is reputed to happen in certain NVidia configurations. I'll dig around a bit and try to confirm that.
