I think the same thing.... I also notice a significant delay when the GTX980 resizes the monitor so I'm thinking it's the display driver reconfiguring memory or similar. Why it has to forget the display sizes and frame buffers, should this be the case, it remains to be seen and I can't think of what to do to pre-empt it except disabling sleep which corporate policies prohibit
Recently I have noticed that my computer is EXTREMELY SLUGGISH after I wake it up out of sleep mode. It runs very very slowly. Rebooting is the only thing that fixes the sluggishness but then it happens again once my computer is put to sleep and then wakes up.
My computer is an Alienware Area 51 R2. I upgraded to windows 10 about a month ago without any problems. I have the Hibernate feature turned off as the files required to preserve my computer state during hibernation take up far too much space on my tiny 120 GB SSD that windows is installed on (all my games and other stuff are installed to the 1.5 TB standard platter-based hard drive) Sleep function remains enabled though.
I have a pair of NVIDIA Geforce GTX 980 graphics cards and am using the latest graphics drivers with them (358.50 according to the latest update i got).
Defragmenting (and in the case of SSD, trimming it) have not helped.
Anyone able to help?
