Here too. I can't run KDE4 at all. It's like running XP on a 486; just terrible. I'm running 177.13 and 2D performance is really bad.

Hi all,
I had (!) the same problems as most here are describing.

What worked for me does not neccisarily have to work for others.
Reading this forum I decided to try a few of the suggestions.
For me the options added to /etc/X11/xorg.conf;
1. "RenderAccel" "true"
and
2. Option "PixmapCacheSize" "200000"
work very well.
I have also tried the: nvidia-settings -a InitialPixmapPlacement=2 -a Gl1phCache=1 does not improve anything.

I must recify that this last line... nvidia-settings...etc. does in fact make the resizing/scolling smooth, it must have kicked in later.

For comparison, I use;
-openSuse 11.0 KDE 4.0.85 (and 3.5)
-nVidia driver 177.13
-nVidia 8500GT
-SamSung 24" screen on 60Hz and 1920x1200 pixels.

The scaling of a terminal, that has been suggested as a test, goes smoothly ! Quite different from the 20secs to 2min3secs that I had to wait before. Scrolling in Firefox is perfect again.

The same with the complaint about the terrible fonts in openSuse11/KDE4.... I gues it is the nVidia driver that complained (OK, gave an error message) that in /usr/share/fonts/TT does not exist, so I had a look and found that the file is called truetype i.s.o. TT, made a TT folder and copied the truetype fonts to it (probably a symbolic link will also do the trick).

Now I have razor sharp fonts !

The one thing I do NOT onderstand is that since the release of KDE4.0 nVidia had been bashed all over the internet on hundreds of forums.
There seems to be an aknowledgement from nVidia mods (here), that they are working on a new driver (without any mention of when it will be ready 1 week - 1 year?) and all the time it is just a matter of default settings that need to be corrected.....

Now, If my company was in that situation, I'd have my mods posting answers with (possible) solutions all over the place. It seems a better option than backrupcy

hi,
how about resizing/reducing to taskbar/restoring windows? with these settings you noticed any improvement? I tried all the options found in this board (also these that you're using), but until now i saw no significant difference in resizing windows, which is very poor and full of glitches.
I use kubuntu and i'm wondering if things are different in suse.

bye

I use full options compiz-fusion and resizing/reducing to taskbar/restoring windows is (but always was) as fast as I set it in ccsm.

I have not tried any 'live distro's' yet so I do not know how other KDE based GNU/Linux flavours will work with these setting.... actually I am just enjoying the moment

the kde 4.1 rc1 release announcement refers explicitly to the problems we are discussing here: http://www.kde.org/announcements/announce-4.1-rc1.php
seems like that they are also waiting inputs from nvidia.

there is also a link to this page: http://techbase.kde.org/User:Lemma/GPU-Performance (i didn't knew about it until now) with a very detailed description of the various problems and some workarounds. Unfortunately they does not always work.

bye

btw, does the new gtx 260/280 (or whatever they are called) overcome the 8/9-series issues, or does it persist?

1. Thanks for posting this information, should be helpful to others.
2. Changing settings improves performance but it's nowhere near fixed. The problem is with the driver itself and KDE 4.1 performance is still horrible. The nVidia software engineers need to fix this.
3. nVidia is not going to go bankrupt. The majority of their customers are mindless alien-shooting windows users.

Hi all
Some good news...after taking my 3 week old PC back to the shop and 3 days of stress testing they admitted that a ram module on the card was stuffed... so was replaced...then I got home and all excited to test it out found the my keyboard was not responding... swapped with another one and same deal... returned to shop for a rebuild... so a new motherboard and card... so far so good. the compiz effects have not frozen my system .... before I took my PC in I had installed the new 173.14.09 driver with envy so far so good... SO once again not a ubuntu fault but a hardware issue... as for the issues of performance and so on I am just happy to have a fully working card again and may get more annoyed as time passes but for now I have compiz on and so far so good. Thanks for inputs from all, will keep and eye on this thread from time to time..

I own a 7300GT and a 8600GT. My system is powered by an Intel E6600 with 4GB RAM installed running a x86-64 linux.

gtkperf 100 loops:
7300GT: 6.xx sec
8600GT: 14.xx sec

Flash and KDE4 are suffering most from the bad 2D performance.

I gave 47 for the 7300GT back then and 67 for the 8600GT recently. These results make me feel kind of stupid because I was lazy and bought a nvidia card just because in the past you people had the best linux drivers around. What happened?

Regards,
-- Maik

AFAIK, Flash performance is not related to the nvidia driver. The Flash 10 betas have some major improvements, to the point where I don't get any slowdown in fullscreen etc. but I do have a fairly powerful PC (e8400@4ghz,4gb 850mhz,8800gts 512) so it might just be masking other peoples problems.
