I tested performance of opengl using 6600GT, Debian and Mandriva show the best 3D under linux with Doom3, Fedora came latest, dunno why to be honest...

But just from my experience: red company is quite better at doing 2D - in comparison it just flies, 3D is quite good. Feature wise green company is better at the moment, however red is doing better and better with linux...
Own xorg.conf? Please share.

I have an 8200 and have to dispute the advice in the 1st post.. for best full-screen flash performance (on hulu hd or The Daily Show), 173 gives me FAR superior results to 177. On the down-side, that also mean no HDMI audio (177 needed for that). (YouTube is ok with 177, the others are not)

I have filed a bug report to nvidia with the info.

Its been a lovely (not) introduction to the (at-home) linux world (work user for 15 years).. 50+ hours trying to get a system that plays media at even 50% of the performance I get by rebooting in Vista (using the exact same HW).

Same problem with Geforce 8200/8300 IGP and driver later than 173.xx.
Extremly poor desktop performance with driver 177.xx and 180.xx.
You can see how your background picture is drawed line by line on the screen.

NVIDIA PLEASE FIX THIS SOON!

I gave up, and got myself an old PCIe card.

The 8200 does well for me in mplayer/VLC.. the only place it falls flat is full-screen flash... which would make one want to blame the flash plug-in, except you can show a magnitude of performance difference by DOWNgrading to 173 (from 177).. so while Adobe probably has some share of the blame, there is a very repeatable and obvious performance degradation that occurred between 173 and 177, suggesting that there should be a way to reverse that issue that is well within nvidia's control.

Well, I came across this site for the same reason everyone else seems to have been brought here. Its sad to say I was hoping to find a solution after reading pages upon pages of the same problems over and over again, to which I am having similar issues. Using openSuse as my Distro, I was asking around in the IRC about ATI. I got a bit of mixed emotions, but all the negative ones seemed to be just an issue with installing the driver. Nothing really came up about the performance.

So, nvidia, you have forced me to try out your competitor. I will gladly put up with maybe a few hours of pain full driver install ( depending on just had bad it really is ) for a smooth desktop from that point on.

Once I get it, and install it. I will gladly post back here how it went.

I'm using quite similar config for my 6600GT, of course some things are commented out.

P.S. I'm trying to get my hands on some x series of cards from the red graphic chip manufacturer, as I'm turning my old desktop to silent 2D machine, I'll share my experience here when I'll get one

Nope, still have horrible 2d. thanks anyways. Deffinitly going to switch to ATI. And if its better, I will be staying with ATI.

Have you restarted Your X afterwards? Anything in xorg log filles? Have you tried backingstore?
There are combinations to try, also, please check what gtk theme you use, because some of them are really slow... I'm using rezlooks, they are really fast... Not like windows but I find rezlooks the fastest...

I'm beginning to be totally fed up with GeForce 9300 / 730i mGPU on Asus P5N7A-VM. 2D is still slow with 180.22 but the worst issue is dual head related slowness. E.g. scrolling in Firefox in one screen while watching TV or video on other screen causes the latter one to halt to grind. I'm getting a second hand 7600GT PCI-E card since 7300GT on my previous setup was fine.

I have to say, I wished I owned a business where I could give such lousy support that a customer would then spend $$ to buy a *2nd* product from me

Wow! Just installed the Asus 7600GT into my P5N7A-VM, disabled the mGPU from BIOS and suddenly _all_ performance problems are gone! 2D is super fast. No tearing. Full screen flash is smooth as hell. TV/video running full screen on screen 1 plays smoothly no matter what I do on screen 0.
