177.76 report
Being the guinea pig that I am, I upgraded from 177.70 to 177.76. For reference, I have a Dell XPS 1730 with an 8700M-SLI.

The Bad:
  • The external panel is still not detected on startup. Switching from the internal screen works, but the external panel was properly detected back in 177.16 (-ish... I forget the exact point release)
  • The clock frequency is still stuck at the lowest setting which makes most games unplayable. In nvidia-settings, the other two available clock speeds are greyed out.
  • I may not have mentioned this in my last couple of reports, but 1 core of my dual-core cpu is still occupied by a flood of interrupts from the video card... makes for pretty crappy battery life.

The Good:
  • 2D block move performance (scrolling) seems to be substantially better than 177.70 --- and is livable, but still not up to (say) the standard set by my matrox millenium G500. Large solid window moves are still sluggish.

Re: 177.76 report
I'm seeing nice improvements with everything, assuming I use IPP=2. Firefox tab switching is much improved and text scrolling seems slightly better. I'm using a GeForce 9600 GT on a workstation with KDE 4.1. I haven't tested all of my 3D and opengl performance yet, just day to day tasks.

Re: 177.76 report
Where do you put IPP=-2?

Re: 177.76 report
After you start X, run this command:

nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1

That should speed things up for you.

Re: 177.76 report
That seems to make a moderate difference, thank-you, but performance is still below what I would expect for this amount of video hardware.

Re: 177.76 report
Yeah, that's what I am seeing now that I am finally spending some time to test things out. I'm just not happy with the performance overall. I'm still messing around with different config options in X and other stuff and will let anyone know if I find something but I think we will have to wait for another iteration of the driver before performance gets where it should be.
