Hi, Win 7 x64 AMD rx480 8gb 17.3.1 drivers (cleaned with DDU safe mode before installing) 16gb ram i7 860 @ 3.52ghz 3 x 1080p displays @60hz No HDMI audio driver Desktop is fine and smooth across all 3 monitors until I enable eyefinity, then it feels sluggish and like it is only refreshing at 30hz or maybe less, dragging windows looks awful like there is no driver installed. Tried ClockBlocker / Aero off/ Power saving is at max performance Been fiddling with it all day - no joy ;( Any ideas? Cheers edit: Games seem to run fine, looks like its just the desktop that has this effect
Similar / same problem here, solved by reinstalling different drivers http://www.tomshardware.co.uk/answers/id-1847755/poor-eyefinity-performance-games.html Try using DDU to remove the old ones in safemode first, then reinstall in normal mode
Went through countless driver revisions, no change. Solved it by having a display port cable from card to one of the monitors - I was using a passive display port to hdmi adapter and this was the cause! Thought I would report back in case anyone else has a similar issue.
