KDE 4.1 Speed Tweaks?

English Install/Boot/Login
#1

Decided to enable buildservice and upgrade to 4.1 RC.

So far, so good. Running much better than 4.0 was. However, when I add the Folder View plasmoid, it’s really, really slow. My machine should have no problem handling this:

AMD Phenom 9500, 3GB DDR2, 8800GT, Nvidia 171 beta driver.

Any tweaks to speed up Plasma?

on my 1.4 Ghz Pentium M laptop I have no real speed problmes with KDE 4.1

#3

Well, that’s certainly a good thing. :slight_smile:

I like the Folder View plasmoid a lot. However, when I try to move it, it’s like moving through jello. I’m thinking it’s a 2D problem or possibly and XGL problem. Not sure.

Anyway to speed things up for plasmoids and widgets.

I heard that there were perf issues with some Nvidia cards, though my 7300gt
works fine but iirc 8800’s seem to have issues - try upgrading your drivers
to 173.14 (or newer if there’s any)

Suse 11.0 x64, Kde 3.5.9, Opera 9.x weekly

Scrolling and many other effects are horribly slow with the Nvidia driver unfortunately.

#6

I tried some of the old fixes like “RenderAccel” “On” but it didn’t help. Guess I’ll just have to wait for Nvidia to get out a better driver.

#7

Someone suggested a config to take off hardware xrender acceleration to a software acceleration and that improved performance, but I can’t remember where. I imagine it is in the KDE 4 desktop effects somewhere. I just don’t use KDE 4 personally.

#8

I’ve tried xrender and OpenGl with every combination of settings.

It’s weird that a game like Second Life runs better than is does in Windows, and yet resizing windows is like running a Pentium III.

:frowning:

Thread moved to Pre-Release/Beta

#10

It is a common problem of nvidia 8000/9000 cards:)

Yeah, I’m getting that impression. It’s not nearly as pronounced in KDE3. Must have something to do with composite or Plasma. And the drivers, of course.
