Same card in Windows is flawless. 3D gaming is fine in both Linux and Windows.
I've a 8600M GT (on a laptop). 2D is fine, using latest 177.xx beta driver and initialpixmapplacement=2 and glyphcache=1. 64bit Ubuntu 8.04 BTW.

whilst it is usable compare it to vesa (using kde4:resizing, tearing off menus) .....Its quite a bit different. Gyphcache and ipp=2 make the most difference in text heavy apps, for rest not so much...unless you're using simple widget styles etc..

For KDE4 I can't say anything else than that last time I tried it (2 or 4 nvidia driver revisions ago) it was so slow that it was unusable.

Hey Aaron, how large is the Linux development team anyway? I want to get a better understanding of the situation.

As a design engineer I just have a hard time imagining what's going on here. A 16.7M color screen at 1920x1200 is just under 6.6 MB of data. My old 2.8GHz A64 (single core, agp 7800gs) has 7.8GB/s memory bandwidth (dual channel DDR500). AGP 4x/8x is 1-2GB/s.

Recent PCIe is 8GB/s, and DDR2-1066 is 8.3 GB/s per channel.

Where are the cycles/bandwidth being spent on X + 8/9 series cards that it can't compute 6.6 MB of 2D data in less than ~8 ms? It should be able to composite ~4 full 1920x1200 frames in that time, in software.

Yeah, it's weird, indeed.

I just noticed something. I think that the problem becomes much less at lower resolutions. Again, I'm not sure of this. I tried messing with my xorg.conf while trying to install the 177 drivers and set it to 800 x 600 resolution and everything ran a lot smoother. There was still lag, but it was a lot better. But of course, no one is going to run 800x600 on a $200 card. Also, I'm not sure of this, it could have just been me doing something stupid.

Ok, I just did that. There is a HUGE improvement for me. It still nowhere compares to my friend's ATI on Linux, but I can actually resize a window and not wait 30 seconds for it to redraw. I need to stick this in my startup scripts somewhere.

The interesting part for ME at least is that:

InitialPixmapPlacement=2

Kills my performance.

I seem to get the best performance with it at 1????

the problem is how it computes it (basically it isn't) and where the data is going. I suspect the reason vesa and nv are so good at this compared to nv is that acceleration is done solely by the cpu. Nvidia does not accelerate everything so when an operation it cannot accelerate appears it has to pass it off as software incurring a huge peformance penalty.

Curiously, Youtube has changed something that makes their full-screen video mode completely smooth on 8xxx series cards under Linux.

The BBC's iPlayer is still stuck in super slow mode, however. I guess it wasn't a change in either the NVIDIA driver or Flash itself.

Hi all... this is a sad place for me... I have been banging my head against a brick wall for a a while now trying to get my card to work well in Hardy 8.04.
Card details as follows
Galaxy 512 GeForce 8600 GT, driver.... what ever I can find to work on the day... latest the back to NV , I have tried to get answers fron the great launchpad.net site and all there have been very helpful but I stumbled across this thread and my hopes were dashed..

These are the symptoms of my machine..
I am using Ubuntu Hardy and update every day.

Installing the drivers with the " system.... hardware drivers , or Envy or direct from Nvidia do not have stability.
My system still freezes randomly... only the mouse can move but that is it, keyboard locks up so I have to do a hard reset ( I hate doing that)
The system is most stable when I use the NV drivers from " applications... other ... screens & Graphics"
My card is a Galaxy GeForce 512Mb-8600 Gt Nvidia card... I assume that the manufacturer makes no difference as long as it is a Nvidia chip.
I would like to start using the extras visual effects but I need the 3d acceleration stuff and as soon as this is enabled by downloading the drivers my system becomes unstable. Just a side note I had to set my monitor to a generic LCD panel 1280x1024 because If I let the software detect it ( Viewsonic VG700-b) I loose the edges in the longin screen and have to use the F10 option to change sessions if I need to. ( I would term this Distorted Display at longin)
I thought it was only when I enabled Compiz but after crashing there I removed it and had no visual effects.... still froze, my temperature seems to be about 42 to 44 degree C
What I see just before it locks up is a flicker or 2 on the screen, then it's all over this happens about 1 min from when the herron desktop picture shows up. I had to go in on recovery mode and got the x org something to reconfigure ..... now stable but no compiz stuff.
