I know it is off-topic but i need your help
After long time using DsPlayer Jarvis 16.1 , i tried to run Krypton 17 , four days ago
But i am surprised because using XBMC and Kodi many years , now i see for first time that the video player is not working properly
When video plays , it stutters , it jumps ( i do not know if i write the correct words to express my problem because English is not my native language)
I am trying also to run the Jarvis 16.1 just overwritting the Krypton with not the use of the DsPlayer , but nothing

With letter ( O ) , it writes in the Video Stream that the Hardware decoding is Inactive
Is this the problem?
If Yes , how can i make it active?

Also i see that the mouse is not working properly and smooth like before
For your info , i am not using and Video Add-ons

Thanks for your attention
