Slow Streaming & Some Streams Not Working in Krypton

Recently have been testing various Krypton builds on many devices, from the beta to the latest nightly. It is slow to play many streams, let alone the switching speed, but its working perfectly in older kodi builds. There’s also some streams which crash and refuse to play. Ive also tried these particular streams as .strm files and they also have a problem. Does this indicate a problem with Krypton or something with iptv simple client?

Seems to come up with the error with most streams, some play after about a minute and some refuse to play ERROR: DXVA::CProcessorHD::IsFormatSupported: Unsupported format 104 for 1.

Heres is a clipping of the log file
