RE: Inpiron 15R 5537 - Bad game performance or unability to Sleep/Hibernate?
I'm having the same problem with the same laptop.
With Dell drivers, newer games are unplayable.
With AMD generic driver, everything is playable even at max, but when entering sleep mode, the laptop freezes.
Guess we'll have to wait for an updated AMD driver by Dell, the question is when it will be released... the current one is made in October 2013! -.-
