Lagging issue seems to be fixed after 10.8.1 on rMBP

Funny thing is there was never lag going from right to left switching spaces on the Intel chip (from desktop 1 to 2), but there was a bit of lag going right to left (2 to 1). Now, however it is the opposite. Not as much lag as original, and not a big deal at all, but again, kinda funny.
I'm interested in the battery life as well. I guessing Apple wont say there is a fix for battery life it will just get better.
Actually the lagging still exist... I don't know why it was smooth right after boot.. But lag returns after a few minute of usage.. Maybe the Dedicated video card was running at the beginning
For the battery.. I have 7 hrs at the beginning. And showing 5 hours after when I using it for like 5 mins..
Mine was silkly smooth, then when I got home and didn't have it connected to 2 external displays it started stuttering again.
I wouldn't say my lag is fixed, it's definitely better though. I still get quite a bit of lag when I am zoomed in with Safari and there's lots of text or images on the screen.
I'm still showing signs of lagging. Still have stuttering music in iTunes and stuttering video in YouTube. Really not happy about this.
I only have a little UI Lag/lagg back on the full HD scaling, but if i change it to the Best for Retina i see nearly nothing lag/lagg, so its getting better so if they can fix it totally in 10.8.2 i would love it! 
I'm back at work and once again, it is going super smooth again! I always force discreet when I'm plugged in, that is not the issue.
When I went home I was using discreet with no additional displays and it was choppy as ever. Now I am plugged into 2 displays and it is smooth again.
The problem is safari scaling! If you move safari to an external display running at native resolution everything is perfectly smooth. If you use SwitchResX at any unscaled res it is perfectly smooth. If you set SwitchResX to 2880x1800 then open facebook in safari and zoom in on the content it will be choppy. So its 100% a safari problem....not an OS issue.

Ugh, sounds like Apple is simply unable to fix it with software tweaks. Guess we'll have to wait for Haswell next summer.
Fix what, Safari scrolling facebook? Sounds like a trivial fix to me. Probably not their highest priority which is why they didn't consider it high priority.
These type of optimizations are not going to be in the first 2 updates, they're almost always going to be improved at either 3rd or 4th updates (10.8.3/10.8.4).
I got my MacBook Pro Retina this past Monday. It came with Mountain Lion 10.8 installed. i had absolutely NO lag. installed the 10.8.1 update today still NO lag. that's with a LG display as well.
Clean Install
Just an FYI...
I decided to make a bootable USB of Mountain Lion last night and do a clean install and I have to say that the difference is remarkable for me.
Much snappier and more responsive.
FWIW!
I almost forgot, the battery life seems much better today so far, but I will reserve judgement on that till I've run it a couple of days.
