Have been on 14.2 Helix for 5 years now, and thinking of slowly moving over to 18.7 or the new Matrix when it comes out.

My video playback with 14.2 Helix is butter smooth, i have the following setup;

Panasonic VT60 Plasma
Yamaha RX-A3020 Receiver
Windows 7 64Bit
AMD A10-7850K APU

Running HDMI /Passthrough, and a audio delay of -175ms in advanced settings.

However, in Leia 18.7, using "Adjust Display Refresh Rate" Kodi switch my TV to 24Hz as it should for BluRay's, but the playback is extremely slow and choppy. Disable this feature everything is fine.
This works as mentioned, flawless in 14.2

Is this a driver/software isse? Windows? Is my Hardware to old?

I'd say your 6 year-old hardware is probably the culprit. I had the same problem with a similar old system, everything worked fine in Kodi 17 but 18 would give me problems with 24hz. What I did was used Whitelist so that it only switched to 50hz/60hz and not 24hz. Doing that means any 24 fps content is played at 60hz with pulldown, which whilst not ideal is adequate enough. Most people would barely tell the difference using 60hz for 24 fps content anyway.

For me, using pulldown is completely out of the question. 23,976/24p blurays need to be played with my Plasma set to 24Hz, i cant stand watching with 3:2 Pulldown.

So is it Windows 7, or my AMD A10 APU which is most likely to be the problem?

And why is 24Hz a problem in 18.7 and not 14.2?

I don't know, I'm only going off my experience. You could try 17.6, that will probably work but I don't know what changed in 18 to cause the issues.

There's been a ton of change to the video player component, and for Windows I think it is now optimized for newer WDDM/DirectX. You can try playing with the rendering settings and see if that makes a difference. Or try a direct usb boot of libreELEC.

It turned out to be "Use Fullscreen Window", i had to disable it.

24p content is running as it should now.
