Slightly laggy with the integrated graphics. But still, much better than on Lion. With the discrete graphics there's no noticeable lag.

Lag was greatly reduced in 10.8 DP4 compared to Lion in Safari, but Chrome is still pretty jerky when it comes to scrolling.
Can anyone with the GM compare Chrome scrolling to DP4?

Wow.. lag seems to be fixed...
Can you try full 2800 res. without any scaling to see if any lag exists.
Past reports indicated that native resolution never experienced the lag issues. In general, everything I've read indicates it's worst when using the scaled 1680 and 1920 resolutions.
Can you try Facebook + integrated graphics + Firefox? I saw a video demonstrating better scrolling smoothness with Firefox.
Scrolling is hardware accelerated in Safari 6 in Mountain Lion, so I somewhat doubt this is still true.
I've decided to stick to my plan of waiting until the 2nd gen retinas are released. The lag is better but not fully gone, but more importantly I want to avoid any "first gen hiccups" altogether. Plus I want all the apps I use to be supported once I upgrade.
Just tested with Firefox 14.0b10!
It is FAST FAST FAST!!!
But no retina graphics and every letter is horrible to watch
So let wait and see if it's the retina making everything slow or if Firefox can be the king...
Thats never had a lag problem. I only run at a full unscaled 2880x1800 and its never had the lag problem since day one. I could see it if I used scaled resolutions.
With Chrome beta (Retina supported very well), scrolling lags like a hell on the iGPU. With dGPU, it was better, but still much worse than Safari.
Chrome Canary build worked much better, though. Scrolling performance was pretty close to Safari. So I guess Chrome beta may have hardware acceleration partially disabled for the rMBP due to graphics resource leak which leads to kernel panic.
Here's my experience on the GM:
Safari: Very good, no lag and scrolling is very fast (don't use Facebook so can't test that one).
Switching from Desktop to Desktop, or full-screen app-full-screen app, etc.: Very good and smooth no lag or jerkiness.
Mission Control: Laggy and stutters, rather disappointing (smooth on dGPU).
Launchpad: Smooth with no issues.
TextEdit: When you have a few pages of content or some tables, scrolling and what's displayed is very choppy and it takes a lot of time to redraw everything. Performance is very bad, though vastly improved from Lion. Sucks on both integrated and discrete GPU.
If you'd like me to check other UIs let me know.
Update: iphoto is very good, and automatically enables the dGPU upon launch.
Test conducted on Best for Retina setting.

From what I've read Canary shows a big improvement in scrolling on ML as well as Lion.
I dont understand people not wanting a rMBP because web graphics look ugly. Nobody returned their 1080p TVs when broadcast stations only had 480p content. Graphics on the internet look like crap so your gonna buy another machine with a crap screen to match it? bizarro
Just finished installing Mountain Lion on my rMBP and its like a whole new machine. Everything is lightning fast. Can't believe how slow Lion actually was.

I agree. Mountain Lion on my 2008umb was way faster than Lion was. This feels like one of the most optomized builds of OS X to date honestly.
exaclty. i feel bad for all the people who returned them because of the stuttering. But i can understand why, Its been a slippery slope on the launch of these things. I just done get people returning them because web graphics looks bad. Then they buy a low rez screen because it makes the web look "better?".. Theres this weird notion that a rMBP is making things look bad, when its really just exposing them. MS and other developers need to get on the ball. all screens are going to 4k in a few short years..
Im REALLY glad to hear ML fixed things, thats awesome
I honestly don't feel bad for those people. Anyone who returns a laptop bc it doesn't scroll facebook fast enough blows my mind. They knew it was new tech and that the software that would fix it was right around the corner.
