Default Re: Linux users need a good driver for nvidia products!

well trying to change size of text rarely works fine on firefox (also 3b3) even without flash (even more if you try to change it for examble by pressing ctrl and doing a quite big scrool it will take at least something like 5 10 seconds).
page up/down doesn't give me problems in firefox2+flash on that site.
doing a single hit size change takes for me 1 second even on that site

you know that voltage regulator thingies on your board? You know, that the bios does more than setting ram speeds - like setting the signal strenght on a couple of 'busses', like agp, or sata or pcie?

So a different bios might drive the pcie-bus with a stronger signal (more volts) which might be able to solve line noise&low voltage related problems.

This is spec'd and adjustable only if designed on the board. You would need supporting circuity like DACs to be able to "Adjust" any voltage on a bus. This is the case for CPU's, Memeory and such but I don't think systems like PCI, PCI-E have provisions for adjustment. Point is the voltage is set stiff from the manufacturer and not accessible by the BIOS. At least not on my board. The extra DAC's for this would add cost.

Great thread. Thanks to NV for supporting Linux but my 5900 was still way smoother than my 8800GT, including Windows.

just because something is not user adjustable does not mean that it is not there. Secondly - ever thought about options like 'Driving Strenght' or 'Spread Spectrum'?

and back on topic:

my desktop is fast and snappy. There is no lag. I can scroll, I can change font sizes - and everything is prompt without delay.

But:
I don't use gnome. gtk IS slow (and gnome a memory hog).
I don't use firefox, which combines the worst of all worlds.
My xorg.conf is clean, without garbage.
My Bios is set up well. With all the 'Spread Spectrum' options (there are at least three) deactivated, but stuff like HPET (which does have a positive influence on X) activated.

I don't have lockups. I don't have lags. My desktop is faster than with my 5200 or 6600.

Because your 8600 has a mature driver and has been supported since the 100 series drivers. The rest of us with GT's are stuck with 169.*

Spread spectrum has nothing to do with voltage but a method for increasing bandwidth. Checking it makes things less stable...not more.
Admittedly I have no idea what Driving Strength is. What is it?

I have resorted to not using Gnome either. My desktop is really snappy since I switched to terminal and wget.

Hmm, I like the 169.* and 171.* drivers... (e.g GlyphCache, PowerMizer display, OpenGL 2.1.2, ...). And I'm glad that I'm not stuck with the 100.14 or 9755-something... YMMW

well?! but you still need some kind of silicon for the spread spectrum feature, or not?! I think this is energyman's point...

well, just replace "Driving strength" with "Signal strength"... (a famous example was the AGP Driving Strength on VIA's 694X)

Gnome and in particular gtk is dog slow...however using compositing slows things down even further (nothing new there tho) but I find that powermizer makes things even worse under compositing (and xrender as it depends on the 3d engine of the card).

minimizing windows and quick animations (or dragging) is really sluggish due to the latency between the time it switches to full throttle and when it is idle.

render usage does not change the powermizer throttle. I can double performance under some operations by forcing the throttle to maximum which is a less than ideal solution. I don't know how much of an effect this is on real desktop usage as render benchmarks are all synthetic in nature.

2D accel sucks big on nvidia.

I changed from a laptop with a concurrent board (read ati) with 1/2 of the clock frequency and 1/4 of the memory and I find the present desktop experience incredibly sluggish compared to that.

And I don't have any eye-candy active, no compiz/beryl, no transparency. Moving/resizing/scrolling windows is painfull, the CPU and fans just fire up high.

I'm slowly moving away from nvidia. It sucks paying for this.

Oh, and not to mention the garbled display, application buttons that disappear and strange artifacts that appear from out of nowhere.

sounds more like overheating than anything else.

It is amazing how many blame the software before they check out the hardware. Just because it "works" in windows does not mean that it is good hardware .. garbage works in Windows .. just look at WinModems and 29.99 printers!

A weak power supply, poor air circulation and faulty fans, bad interior cables, slots that were filled with dust bunnies that were not cleaned out when a card was plugged in .. the list goes on and on.

I don't use projectors so I can't comment on that issue, but for me the Nvidia drivers have been pretty good. I've been happy with all my Nvidia cards on my Linux boxes. (Currently 8800GTS)

The only thing I have to complain about (and this is not trivial to me) is UT2004. ('Nuff said about that. They've said it will be fixed in a "future driver release" )
