Default Re: nVidia 8000/9000 Series Performance Issues

I've got a 8600gts and have absolutely no 2D problems at all. No problems in KDE, nothing is slow. I'm using 177.70, with nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1 and my xorg.conf:

Option "PixmapCacheSize" "2500000"
#Option "UseEvents" "on"
Option "DamageEvents" "true"
Option "OnDemandVBlankInterrupts" "on"
Option "TripleBuffer" "on"
Option "backingstore" "false"
Option "AllowSHMPixmaps" "0"

Normally I get these results (1000 iterations):

But I've an e8400 clocked at 3.6ghz, so I decided to under clock to 1.8ghz to see how much this smoothness relies on the CPU, and I got this:

Which is still good, I still can't see any problems, and it isn't my CPU which makes everything so smooth. In fact the only problems I have with 1.8ghz, is resizing firefox3 in KDE4, it's responsive, but a little unsmooth.

i've got 8600m gt 512 mb ram and i use the latest beta drivers 177.70.. everything is working just fine.. these drivers made a lot difference.


my time in gtkperf was 128.. and after installing 177.70 drivers :

pmousoul@acer5920g:~$ gtkperf -a -c 1000

compiz with gnome became much smoother too!


keep up the good work nvidia guys!

Hello, I read this Thread since almost the beginning and I hope each time I come to find the magic solution!

I have a quadro nvs 135M and I saw a real improvement with IPP=2, scrolling etc...
but not for a long time:
After roughly an hour of usage, tab switching in firefox is slow (2-3 sec to render a page)

So I have to go back to IPP=1 and now tab switching is fast but scrolling some pages is slow

Do you have this issue?

Ugh sometimes firefox does that to me on my plain KDE3.5 6600gt setup... restarting firefox fixes it right up everytime. Certain pages seem to cause FF to get slower and slower even after the tabs are gone... does restarting FireFox make it fast again?

7800gs: I have figured out that kde 4.1.1 konsole tab switching is about infinitely faster with driver "nv" than driver "nvidia"(177.70)+xorg.conf+nvidia-settings. Huh.

The situation is complicated, indeed.

edit: Okay, this is the fastest - turn off all desktop effects, and disable autostart nvidia-settings command. Restart x.org after these changes. Then everything 2D seems to be lightning fast. Some of us have work to do.

(update: btw, 177.76 made tab switching in konsole tons faster with desktop effects enabled.)

That is simply not true - this opinion seems widely spread.
Just because using OpenGL in some cases does not mean everything is done on the GPU, e.g. the whole trapezoid/triangle geometry generation is done by the CPU, rendered in software and copied down to the GPU.

In theory a dedicated 2D driver providing good XRender accaleration should be almost always be faster than 2D on top of OpenGL, just because of the fact that OpenGL is so flexible, even NVidia mention that in one of their presentations.
Although the latest beta drivers are still not 100% there, they are a step in the right direction

txf,
That qgears test is heavily bound by software work in Qt. I stubbed out the trapezoid rendering in the X server and it only runs at 75 fps on my system.
Code:
samples  %        image name               app name                 symbol name
77072    37.7245  libQtGui.so.4.3.3        qgears                   (no symbols)
44158    21.6141  oprofiled                oprofiled                (no symbols)
11416     5.5878  libc-2.6.1.so            qgears                   (no symbols)
10844     5.3078  no-vmlinux               oprofiled                (no symbols)
10787     5.2799  no-vmlinux               Xorg                     (no symbols)
9725      4.7601  no-vmlinux               no-vmlinux               (no symbols)
6892      3.3734  libm-2.6.1.so            qgears                   (no symbols)
5757      2.8179  no-vmlinux               qgears                   (no symbols)
2745      1.3436  libQtCore.so.4.3.3       qgears                   (no symbols)
2736      1.3392  libX11.so.6.2.0          qgears                   (no symbols)
By comparison, here's what the profile looks like with OpenGL (~320 fps):
Code:
samples  %        image name               app name                 symbol name
49387    19.2408  libGLcore.so.180.00      qgears                   (no symbols)
44284    17.2527  libQtGui.so.4.3.3        qgears                   (no symbols)
44181    17.2125  oprofiled                oprofiled                (no symbols)
39888    15.5400  libm-2.6.1.so            qgears                   (no symbols)
31532    12.2846  libQtOpenGL.so.4.3.3     qgears                   (no symbols)
12534     4.8831  no-vmlinux               no-vmlinux               (no symbols)
10550     4.1102  libc-2.6.1.so            qgears                   (no symbols)
7732      3.0123  no-vmlinux               oprofiled                (no symbols)
6838      2.6640  libQtCore.so.4.3.3       qgears                   (no symbols)
I'm not sure why libQtGui is so much faster at feeding trapezoids into OpenGL than to X, but there it is.

The point of that blog-post is that this single test performs better on OpenGL than on XRender.
The intel driver on the 965 is known to be really broken performance-wise (this is currently worked on), and the NVidia driver used did not accalerate XRender (well), whereas the new beta is a lot better in this regard.

I said "in theory", however drivers still have tons of correctness and performance problems.
So my statement was that not "XRender" is slow, but rather driver implementations are poor.
However I have to admit that I am not at all happy with the approach to use trapezoids as the one, universal geometry primitive.

177.80 is out! For those of you who have installed 177.80, have the 2D performance issues been fixed with the 8k and 9k GPUs?

I use nvidia 8600M GT with drivers 177.80.
I's better but performance problems remain.
