KDE The KDE team has released KDE 4.3. This release comes packed with improvements and bug fixes - in fact, over the last six months, 10000 bugs were squashed, 2000 feature requests handled, and 63000 changes were checked in by 700 people. We've already talked about this new release in quite some detail last week, but let's take a look at the most important new features anyway.

Basically, use an Intel chipset and your distro's drivers or an nVidia chipset with a recent driver. Many nVidia driver updates specifically fix KDE 4 issues, especially with Xrender. Your mileage might vary with ATI, but you'll be hopping around with the ati, radeonhd and fglrx drivers and stuff like Xv will still be broken or working poorly.

I *am* using an NVIDIA card (6200, 128MB dedicated RAM) with a recent driver, and KDE 4 is STILL showing BAD performance. Resizing especially is unusable, and various other animations are jittery.

The exact same card with the exact same driver has NO problems with Compiz - which is smooth as butter.

Can't explain that then. I have a 7300GT (mainly because I knew that it still supported XvMC) and that works pretty well. The 9500GT didn't work well but does with the latest drivers. Mind you, I suppose when you're using binary drivers and different combinations of chipsets then mileage varies. The fact is that they will have a tendency to fix things in the most recent chipsets first. I've still seen some strange issues with Compiz, mostly related to resizing. It still seems as though nVidia falls back to software rendering on some chipsets for certain things.

The Intel stuff seems to work better than anything else and works pretty well across the board for Compiz and KDE 4, apart from that known cock up that Ubuntu inherited in their recent release that slows everything down.

It's a complex area, but the common theme is they're graphics issues regardless of whether some things work OK in Compiz or vice versa.

What driver version are you using? From what I could gather (and mind you, I haven't reached KDE4 performance zen yet), not all generations of the nVidia driver have been fixed, and the oldest ones might even be doomed to never get officially fixed I'm afraid.

I'm using an old GeForce FX 5700 here (not the most up-to-date hardware out there, but should be more than enough for running KDE4) with the 173.14.18 drivers (I think nothing above it really supports my card). Seems like there's a new revision of this driver and I might try it soon, but so far performance is pretty choppy.

Anyway, some time ago I decided to give the nouveau drivers a go (http://nouveau.freedesktop.org) since I was getting desperate about the bad performance of KDE4. Much to my surprise the 2D performance was *greatly* improved (resizing and scrolling suddenly became really smooth), but at the expense of completely dropping 3D acceleration and some 2D features (like being able to view webcam streams in Skype, for some reason). I can live without 3D acceleration (it's been ages since I've played any games), but Skype video is a must, so I had to go back to the closed-source drivers, but I'll keep an eye on the open-source one, seems like they are doing things right.

No clue there as to why - my only problem is resizing (I wouldn't call it unusable though). No jittery animations here (except when I connect my 40" LCD TV ;)
