yeah i do have that to..guess thats normal

I tried. Running at 1080p preset high settings. Getting constant 60fps with V-Sync.
You obviously didn't read my previous post. I had tried COD AW, BF4, Watch Dogs, AC Unity, Crysis 3, DA:I, Far Cry 4, Diablo 3 and Dota 2. Watch Dogs and AC Unity is having issue playing it on High settings 1080p. I got no idea why.
I set everything to Low in Watch Dogs and played on 1080p. Getting 10fps. I still not sure how Y50 can get 60fps though, maybe it is different version of Watch Dogs ? I think mine is quite early before the update. So maybe it is not optimized yet. Do let me know which version of Watch Dogs you played that you can maintain 60fps. I may change to that version also.
And also, 20-30fps is considered FAIL for me. I play game only on 50-60fps.

P/S: DA:I, Far Cry 4 and Crysis 3 I know that it is quite impossible to play on 1080p high settings. So it is okay for me.

How much fps you get ? Enable the ping and fps in dota 2 from the Console. Go google for the Console command.
Is it Lobby match or normal pub/MMR match ? I also faced this problem. Now is still the same.
I can get 50-60fps in Lobby match, but the screen transition/when I scroll my view is not smooth. But everything is fine in normal pub/MMR match, I can get 60fps constant with v-sync and smooth transition.
So maybe it is not wifi problem.

encounter problems with insensitive edges of space bar, but not very critical

anyone tried shut down and close the lit (right before the keyboard backlight lights off?). Today got my BSOD again. The last thing I do was that I didn't wait until the light fades before I close the laptop (after pressed shut down).

Is the feature already launched? cause I wanted to buy one now with the latest features. and where do I buy it in JB?

It does look like windows loading file corrupted, how frequent does this happen?

Does this error happen in other games?

If you're not playing BF4 then this problem won't occur right ? I think it is your BF4 file which cause this issue. Original game shouldn't have this problem though
