Sorry for the double post, but did some extensive tests.

Hardware is a Asus Chromebox running OpenElec (EGL Testbuild from fritsch – Kodi 15)
TV is a Samsung F6500 46“ – all Picture Enchancer disabled
AVR is Yamaha RX-V473
Decoding is VAAPI
Renderer is Shader GLSL

Playing a 23,976 FPS Test File:

Refresh rate 60hz with and without Passthrough – no Delay
23,976 Hz with Passthrough – Delay
23,976 Hz without Passthrough – Delay
23,976 Hz without Passthrough and VSYNC disabled – Delay
23,976 Hz with Passthrough and VSYNC disabled – Delay
23,976 Hz with Passthrough and SW Decode – Delay
23,976 Hz with Passthrough and SW Decode and SW Rendering – Delay
23,976 Hz without Passthrough and SW Decode – Delay

If I enable PC-Mode on my TV:
23,976 Hz with Passthrough – no Delay

Like said before, there must be some sort of Input lag or so in normal 24p Mode on the TV, even if all Picture Enchancer are disabled.
