I hope no one minds me raising this here... but
it may be a useful forum since we have
experienced and knowledgeable developers and
hardware designers on this discussion forum...
I know the LL Viewers and hence most of the
others viewers say that the Nvidia cards that
"report as Quadro" don't have the same support or
testing as the consumer GTX cards. But what is
it about these cards or their drivers that is not running well.
On looking at the stats bar, the only differences
I can see relates to KTris per Frame and KTris
per Sec... which are significantly lower on the
Quadro K4000 compared to a GTX 580 and GTX 680.
I have been monitoring my fps rates a bit more
closely than usual recently and I think I see
significantly higher frame rates on a much less
powerful older Nvidia GTX 580 I have on one rig
(with only 8GB of memory and rotating disks)
compared to the system I thought would give best
performance with an Nvidia Kepler-based K4000,
32GB memory and SSD drives on which I seem to
only be getting about half the frame rate. I
tried to set these up with seemingly identical
tests with 1920×1080 display, identical ultra
video, same view distance, shadows,
anti-aliasing, same cache size and network
bandwidth, and everything, and I had my avatar at
same time of day facing the same direction on an otherwise unoccupied region.
I wonder if anyone knows if there is some
specific issue between using the apparently
better fps delivering consumer level Nvidia GTX
GPUs and seemingly more powerful but less well
performing Nvidia Quadro Kepler GPUs that may be a root cause?
