Boot Camp Behavior

When the MacBook Pro with Retina Display first started shipping Apple hadn’t even released Boot Camp drivers for the system. Since then Apple has uploaded a Windows Support package to its servers, and the Boot Camp Assistant will give you drivers for everything in the machine should you ask for it.

The driver bundle and Boot Camp Assistant work with both Windows 7 and the Windows 8 Release Preview, although Apple only explicitly offers support for the former. You don’t have to do anything to make the Windows 8 RP work with the Boot Camp Assistant, just supply the Win 8 RP ISO instead of the Windows 7 image during the Boot Camp setup and you’re all set.

Like all previous MacBook Pro Boot Camp installs, only the discrete GPU is “connected” under Windows. Apple relies on a lot of its own software to switch between processor and discrete graphics which obviously isn’t made available under Windows, thus you only get the dGPU. Apple uses NVIDIA’s 296.49 drivers for the GeForce GT 650M under Windows. Since the standard Windows desktop doesn’t support integer DPI scaling (see update below as you can force 2.0x scaling) Apple picked the next best option and configures Windows for 1.5x DPI scaling and 2880 x 1800 as the defaults. The result is a desktop that looks like this:

At the largest text scaling setting Windows is remarkably usable on the 15.4-inch display at 2880 x 1800. Unfortunately as I mentioned in the Zenbook Prime review, Windows 7 and third party handling of DPI scaling is hardly elegant. While applications that aren’t Retina-aware under OS X tend to simply have blurry text, those that don’t behave properly with DPI scaling under Windows just look odd. Some text elements will be huge and overflow outside of their normal borders, while others will ignore the scaling setting entirely and just be too small. It’s passable in a pinch but suboptimal for certain.


Windows 8 RP on the rMBP. Note the Skyfall trailer is in a full 1080p window

Windows 8 does a somewhat better job, but only under Metro. Metro supports integer DPI scaling at 1 and 2x factors, similar to OS X. With DPI scaling enabled under Windows 8, Metro looks like it would at 1440 x 900 - similar to the default setting for the Retina MacBook Pro under OS X.

00% DPI scaling under Windows 7

Update: As many of you have correctly pointed out, Windows allows you to specify custom DPI scaling modes including an integer 2.0 setting. The result is the same "1440 x 900"-like desktop you get under OS X. Application compatibility still appears to be an issue, check out the gallery below for some examples. Overall Windows is very usable on the rMBP, but just as under OS X the overall experience really depends on application support.

Software Funniness

With the Retina MacBook Pro I get the distinct impression it was launched before the software was ready to support it. Apple did an amazing job enabling Retina support in all of the iLife applications, but iWork isn’t ready for it yet. The system technically launched without Boot Camp support although that was soon added. Then there are the UI performance issues in applications like Safari under the currently available version of Lion. There are also occasional graphical glitches under Lion. the occasional flashing of UI elements, nothing major but just not the polish we’re used to from Apple. Once again, Mountain Lion addresses a lot of this and is only a month out but you still have to deal with reality in the interim.

I also had a strange experience where the CPU clocks on the system magically decided to get clamped down to around 1.2GHz on battery power. A simple reset of the PRAM and SMC fixed the problem but it was odd behavior for sure. I can’t completely fault Apple for this one, as I know I subjected the rMBP to a bunch of strange tests over the course of the past week and a half.

If you’re buying today, just be aware that the best experience will come with Mountain Lion and even then you’ll have to wait an unspecified amount of time for Retina-aware app updates.

    Maybe talking paper specs on the software side it's 'the same' but really that's not even close. Dpi scaling is flaky in Windows anyways.

    And it's really not the same. It's rendered at double the resolution on a screen that actually has 4x's the pixels at the native 1440x900 res. Nobody else does that. Hell, it's rare to even find a 16:10 Windows laptop.

    I don't own a MacBook anything, but some of you sound ridiculous in here going on about Sony laptops with 1080p screens

    What if I, the user, don't want my laptop rendering the display at a pointlessly high resolution just to scale it back down again? I understand the theory but the execution is utterly ridiculous.

    You're right, it wouldn't sell, because the issue is that Windows DPI scaling doesn't work so well. It also doesn't work perfectly in Mac OS (Chrome best example, they had to update it). And so will many older programs, which don't receive further updates, like Adobe Creative Suite <6 don't scale right (assumption)

    That's one reason that Apple released only one MacBook with a retina display, because the software isn't ready for DPI scaling yet. Apple was brave enough to do the step and force programers to integrate scaling in high res images in their programs because future MacBooks will have retina displays only.

    No PC manuafcturer could have done such a step, they would have been blocked by the lack of proper scaling of Windows, rendering a high res display useless because of display errors. So Microsoft should have made Windows 7 resolution independent (just as all mobile OS are, which rely on DPI instead of absolute pixels), then PC manufacturers could have included high res displays which the customer could have used.

    MS Should have with Win7? Hardly. That was too long ago and there were no retina screens yet. Even 1080p screens were scarce. Remember that 99% were getting 1366x768 in their laptops.

    You're right in that Apple can sort of force developers to update apps for support. I do give them credit for usually implementing a solid stopgap. Their scaling for older apps is usually good enough without it being a bad experience. Forcing them to update is a good thing though, having that ecosystem of active developers is good. It's further easier on them to target simple hardware configurations. The benefits of vertical integration at its best. Now for these retina displays to trickle down to all their displays =P.

    Win7 scales perfectly well for a screen this res. Such an absurd panel jump however is meant as bragging rights. It also serves as differentiation. Instead of going "post PC" like W8 transformer devices at Computex, it adds a huge panel. There's nothing special about the hardware that hasn't been done before, except the impressive panel.
  • Ohhmaagawd - Saturday, June 23, 2012 - link

    Exactly what would constitute "special"?

    Mobile operating systems aren't resolution independent. The iPhone supports 2 resolutions, Windows Phone currently supports 1 resolution, but will support 3 in WP8, and Android supports a variety of resolutions, but is NOT resolution independent.

    Frankly, yes I think so. See "the software side of retina" and "Achieving retina".

    I don't think any other PC manufacturer can realistically be expected to do it this seamlessly.
  • UberApfel - Saturday, June 23, 2012 - link

    Apple didn't think of the idea. The screens are simply now available and Apple has the resources and reason to push it to market first. Apple also has their own operating system and software engineers to prepare for such.

    Anyone familiar with the market knows that Microsoft is a big kid nurtured by monopoly and ripping off corporations. The 'big game-changing release & failure' every few years just doesn't allow manufacturers to be first-adopters. Only OSX stays up-to-date, and only Apple may use OSX thanks to either IP or special-order hardware.

    If Asus, Acer, or Toshiba were to shell out the cash to get a portion of the first batch and mass-produce some laptops w/ "retina display"; they'd just have a deficit. Apple is a designer; not a innovator. Anyone who makes that mistake is a fool.
  • MrSpadge - Monday, June 25, 2012 - link

    It's not only about thinking about it, it's about building it and reaching out to make people buy it. It's hard to do this without the "Apple hype", no matter how good and innovative the product may be.
