I updated my Intel HD 530 video driver to ver. 24.20.100.6286 from August 2018. With this driver Blue Iris will not even start with Intel Hardware Acceleration enabled. I just see a splash screen and then the BI service in task manager crashes. To even get back into Blue Iris' control panel I had to disconnect the network cable so that it could not attempt loading the video streams, that let me back in. After playing around I reverted back to driver version 23.20.16.4877 from Dec 2017 which did work fine with acceleration enabled. Some change between Dec 17 & Aug 18 in the Intel driver's has broken Quick-Sync in Blue Iris at least for me. I was not able to find any download links to drivers in-between to narrow it further. Even finding the driver's from 2017 was difficult but I got them here: Intel HD & Iris Graphics Drivers Version 23.20.16.4877 WHQL
