Where are you getting any data that similarly configured Plasma 5 is ANY heavier than KDE4. I have three -Current installs on this box. 1 with KDE4 on hdd. 1 with Plasma5 on hdd, and a 3rd with Plasma 5 on sdd. I don't see what you are apparently experiencing at all. All 3 are within just a four percent of Xfce WITH Baloo et al running (after the first day ofc), within 1-2% without Baloo.

I speak from my own empirical observations.

Apparently, the Plasma5 3D support and effects are optimized for Intel, and it behaves quite decently on a box with Intel graphics.

I have myself two Intel boxes, one with an i3-2120 and another with a Pentium G870, both being quite old 1155 socket and having OpenGL 3.0 graphics, yet still doing their job fine with Plasma5.

However, the story differs entirely in the case of the old AMD graphics like the integrated Radeon HD4250 or the discrete Radeon HD6450, even the CPUs are AM3 quad core and the memories DDR3. For them, the Plasma5 graphics effects (with their defaults) are quite heavy, even otherwise they are decent OpenGL 3.0 graphics cards, which works well for a non-gaming desktop.

And about the older and/or cheaper NVidia cards, let's better to not raise them in discussion...

Long story short, in all honesty the KDE4 makes a significant smaller pressure in the older graphics cards compared even with a well tuned Plasma5. From my own empirical observations.

Excluding the Intel platforms, where they work really well - and that makes me to believe that the KDE programmers are probably die-hard partisans of Intel, which is used exclusively for the development of KDE software.

Thank you, Lucky Cyborg, for expanding on the issue. I haven't owned an AMD graphics card since way before they were AMD and were instead ATi, and that was on a Tandy 8086. I always buy nVidia and,rather oddly, I see almost zero difference between v4 and v5. I say "oddly" because so many devs (and users) prefer FOSS for everything. I, OTOH, coming from OS/2 as my first gui (other than DOS PCTools PCShell) have been willing to pay nVidia for their proprietary needs in return for their excellent service supporting even very obscure platforms.

I am sorry to read that some of you AMD/ATi guys are still suffering. I thought that was largely over since the newer kernel modules. Hopefully everyone will catch up soon.

If you have a Nvidia GPU and are trying to run kde5 with Wayland, you might want to check this post,

One minor irritation I've picked up since the latest update is the behaviour of "Activities".

I use these quite a lot, so that (for example) I can leave a video rendering on one screen, whilst continuing to work on something else on the other. In the past, I've just used the windoze + tab key to switch instantaneously from one to the other. Since the update, switching activities leaves a large "menu bar" down the left side of the screen, eating up valuable screen space.

Yes, its easy to get rid of (right click on an empty piece of screen and click on activities) but its a pain to be doing this every time I switch activities!

Does anyone know how to turn it off?

I had no problems with heaviness or smoothness with KDE 5 using a 10 year old Radeon HD 5670 for the past 5 months until two weeks ago after my RX 560 died. It was just as smooth and fluid as as using newer gpus.

Still, a Radeon HD 5670 is at least five times more powerful than a motherboard/integrated Radeon HD 4250, so YMMV...

I broke my machine, right now I'm using an old 3-core amd machine with an RV630 graphics card (radeon HD 2600 PRO), everything works fine.

So, reducing the blur strength and disabling background contrast, you'll be pleased to see that everything works considerable more fine.

I noticed in the README misses doing these prior to installing the ktown versions, as otherwise one can end up with a startx into the void (and missing libphoton4qtexperimental.so.4, unless you're logging startx with startx -- -keeptty &> ~/.xorg.log):

Code:
removepkg phonon
removepkg phonon-gstreamer
(I couldn't use slackpkg remove kde as I'm using slackroll instead.)
