Default Problem with setting performance level, 180.29, ubuntu 8.10

The NV Clock and Memory clock does not set automatically or manually the highest frequency.
I have laptop Acer Aspire 6930G with GeForce 9300M GS, Ubuntu 8.10.
I've edited xorg file and added following lines:
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x3333; PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1"
However, this didn't help.
Even with default settings driver doesn't rise frequency to the highest value in 3D games(checked while playing in window mode)
Therefore i have much higher FPS in Windows.
Is it a PowerMizer's bug?

it's a known problem although i'm not sure if it's being worked on. have a look at this, thats the whole thing condensed into one thread. for some people the workarrounds help, for others they don't. perhaps consider posting your xorg.conf and a nvidia bugreport log to help solving the thing. well, i go on waiting for a fix.
have a nice time.. =)

I've looked at that thread already, but none of the solutions helped..
Same problem in 185.13 beta driver.
It's a serious bug that doesn't allow to use more that a half of graphics card power.
The question is: why developers ignore it?
It has been noticed 3 months ago and still not fixed...
Kernel 2.6.27-7 and 2.6.29.

It was noticed long before that. Nobody is exactly sure why the developers are ignoring it, because they have so far refused to make any comment on or even acknowledgement of the issue of any sort.

My guess would be that they'd blame the notebook/board manufacturer for not having wired up the GPU properly. After all, for some people the powerlevel switching kinda works.

Actually there was a single reply in januari stating that the problem is being worked at:
http://www.nvnews.net/vbulletin/show...7&postcount=25

My Guess is that some notebook manufacturers did something non-standard in the vga-bios.

But the windows driver seems to cope with that, so why does the linux driver not.

Maybe the notebookmanufacturers also patched the windows driver to work with their special bios or wiring of the GPU.
This should be easy to test.

Try a nvidia windows driver downloaded from nvidia (not from the notebook manufacturer) and see if that works OK on windows.

If that works, then nvidia should also be ably to make a similar linux driver that works.

thats whats my suspect aswell, my manufacturer responded to the question if i could switch the mxm card to an ati one, it would not be possible because the vga bios is somehow implemented into the system bios.
i guess that's also the reason why overclocking the lower performance levels only gives me bull****.

The performance levels do not only adjust the clocks but the voltage too.
So when you are in a lower performance level you cannot just bump the clocks to the one of the higher levels and expect it to work (as the voltage has to be increased for this clocks to run stable).

I know that somewhere in the past this problem occurred also under Windows, at least on Clevo M570RU. (Un)fortunately, I wasn't even able to experience it, as drivers from NVIDIA's website simply refused to install.

Don't know exactly when, but it finally got fixed. I only remember reading about some important improvements and that led me to try once again, which turned out to be successful. Currently Windows 7 in conjunction with Vista drivers works flawlessly

If Windows developers overcame it, then why is Linux still so much behind? I wonder if there's some occurance of communication between those teams.
