InitialPixmapPlacement=2 -a GlyphCache=1 - Fixs kde 4.1 - its amazing

[interzoneuk]

Hi.

Just to let people who are complaining about kde4 speeds on Nvidia and haven't read through all the threads

Just try typing this on konsole (as non-root)

nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1

It makes desktop effects work as well (if not even smoother) than compiz - the best wobbly windows (thanks to the shading - full wobbly is really very trippy..)

Sorry if this is a repeat but so many people are still having issues ... maybe KDE4 should check for nvidia card and invoke this setting automatically ....

how fast is plasma for you? Try moving around the 'Folder View' plasmoid (with default size or larger).

emerged KDE 4.1 over night, and: the speed is comparable to KDE 3.5 with kwin (with effects) or compiz. So: definitely usable. (However, I did not do great experiments with plasma)

Else: still unusable, as not configurable, some services are crashing, kmix is fugly, etc. etc.
But those are not nvidia faults

I must say HUGE improvement with kde4.1 and 177.67 driver!

Big thanks Aaron, Zander and crew!

Dudes, if you don't give us your full specs and describe what problems there were before updating, and what has improved, this doesn't help.

Good morning, there are plenty of threads about this. Just read.


I can confirm the improvements, although moving folderview is choppy, scrolling is now really smooth^^

Stop trolling please. Btw. people on Phoronix forum report that KDE4.1 with the newest nvidia driver is even worse.

I'm glad to see a couple KDE users seeing improvement.

ledoc does have a point where reporting improvement without before+after stats is merely speculation. personally I have seen a vast improvement w/ my gtkperf + compiz where it is only a matter of 20s difference for -c1000. unfortunately i dont' use kde (it's slow) so i can't do testing on that. that said, what's the best kde 2d benchmark to use to test the drivers?

nv did not troll - he described his experience. now your post on the other hand...

also keep in mind that phoronix doesn't like nvidia no matter what..

Phoronix only tested xrenderbenchmark without the tweaks described by Zander so the did ... well nothing.

First you'd like to read the definition of "trolling" again. Then we might continue our discussion

Btw. people on Phoronix forum report that KDE4.1 with the newest nvidia driver is even worse.

Others reported that it is much better right now. Guess what, same happens here. And some people previously reported it is worse are now, after applying some of the tweaks, as well reporting it is better. If I count the replies here, it seems that the "it is better with the new driver" folks are the majority.

So: Did you test it? After applying the tweaks? Was it worse? If you can answer all of these questions with yes: bug report please. If not: just keep quiet, because you'd be the one trolling then.

And for phoronix: the testers there used XRenderbenchmark, which has bad results for some still not supported operations. However, according to nvidia they are aware of this "problem", and it only exists because those operations do not exist outside of benchmarks. Please read the threads on this carefully.

I would say that everything except plasma is faster for me...still not 100% (highlighting fonts is slow without compositing enabled) but better (redraws are faster and as a result compositing is less lumpy too).

But plasma is really slower than it was before...don't know if it is just my distro,my settings or my gpu. Anyone care to comment on folderview (as it is the most visible regression) performance compared to previous drivers?
