Hello,
I had the problem with ig4icd64.dll : game crashed after loading map.
I've formatted my computer twice, updated my drivers with every official tool I found : nothing. It's finally an unofficial tool, able to scan my whole computer, which found me many new drivers to install. Among these drivers, there was one about my Intel processor that the official Intel tool didn't found !
Here is the topic I created : viewtopic.php?f=47&t=60499#p772070
I hope that will help !
