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.

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.

Where do you put IPP=-2?

After you start X, run this command:

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

That should speed things up for you.

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

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.
