Greetings fellow less happy people,
I got farcry 4 a while back installed it bladiebla wouldnt start gave me farcry 4 logo and then loaded for eternity (left it "loading" once for 2 hours), I had this also with portal 2, the work around back then was restart the pc and start portal 2 as first,
I did this with farcry also and BAM 3 sec the logo and loaded, and playing =)
I hope this solution works for other people, Just felt like sharing it, (dunno what kind voodoo trick it is but hey it works for me somehow)
