New for Mid-2012: “Enduro 5.5” Enhancements

When AMD created the Enduro brand, they were really almost where we wanted them. They had dynamic switching with support for most of the latest games and applications, and when it worked properly it would be difficult to tell if you were using an NVIDIA or an AMD dGPU. The problem was when things didn’t work and you had to go into the drivers, and there were several problems. OpenGL support was totally out, many of the latest games were also missing default profiles (and sometimes wouldn’t let you properly specify the correct GPU), the UI was obtrusive and sometimes hard to use (particularly for power users), and the drivers were dictated by the laptop manufacturers and were usually months old at launch and never updated.

While the UI seems like a minor thing to fix—I would have thought one or two months to improve the UI would have been sufficient—at least prior to the forthcoming update it remained largely unchanged. The lack of AMD-provided driver updates was really the major issue, because everything else could potentially be fixed with new drivers and you would never know. The other areas like OpenGL/OpenCL and support for various games/applications should improve over time as well, provided you can get drivers. That brings us to the upcoming Enduro release, scheduled to come out sometime this month or next. Officially it’s still just Enduro, but to help differentiate between the previous Enduro release and the upcoming release we’ll sometimes refer to the new version as “Enduro 5.5”.

The biggest news with the latest iteration of Enduro is that AMD is planning to make universal reference drivers available for all the Enduro laptops. It’s not clear precisely what that means, but potentially any laptop with Dynamic Switchable Graphics or later (e.g. PX4.0 and later) would be supported by AMD’s “reference” drivers. That’s huge, and if AMD can deliver it will assuage most of our concerns with their hardware/software.  Hopefully none of the OEMs get bent out of shape or refuse to allow support, which is a problem we've seen in the past. We should see the first public release in the next month or two, and then another release somewhere in the November/December timeframe.

Besides the availability of driver updates, the UI also receives a much needed overhaul, providing both regular and power users all the options they’re likely to need as far as control of graphics switching is concerned. Open up the switchable graphics options and the top section remains largely the same, but the bottom now allows you to see all application profiles (or just the profiles for detected applications). There’s also a quick search option that works both on executable name and application/game name (e.g. HL2.exe or Half-Life 2 will both find the profile for Half-Life 2). From either list (recently used apps up top, or all apps at the bottom), you can set the GPU profile.

Where previously there were two settings (three if you count “Not Assigned”), there are now three options. As before, “Power saving” sets an application to run on the integrated graphics while “High performance” sets an application to run on the discrete GPU. The new third option is “Based on power source”, which does precisely what you’d expect: plug the laptop in and the apps with this setting will run on the discrete GPU; switch to battery power and they’ll run on the integrated graphics. For many users, everything could default to “Based on power source” and they would be happy, but certainly there will be times where you’re running on battery power but still want to use the dGPU and the drivers give you that option. Should things get squirrelly, you can also reset applications individually or globally to their default settings. It’s worth noting that the power state aware setting is something that NVIDIA currently does not implement, requiring manual intervention if you wish to override your normal settings—though how often people are using apps that require the dGPU while on battery power is something we could debate.

Besides the individual application profiles, AMD is also adding a new area to their drivers: Switchable Graphics Global Settings. This is something you could sort of get before with some laptops, but previously it involved changing from Dynamic Switchable Graphics to manual switching (i.e. switching based on power source) and then forcing the laptop into High Performance or Power Saving mode if you wanted to be low power while plugged in or high power while unplugged. That was clunky and at least in the case of the Sony VAIO C we tested it caused flickering similar to the old switchable graphics, with the dGPU drivers getting unloaded and iGPU drivers getting loaded (or vice versa), with some work behind the scenes copying context from one GPU to the other. It worked but it wasn’t elegant; perhaps more importantly, Microsoft doesn’t want anyone doing this with Windows 8 and thus new laptops won’t be able to get a Windows 8 sticker if they use this method of switching (which basically means no new laptops will do this). To make up for the loss of this functionality (which some people still prefer), AMD has added a new global settings section.

Unlike the individual application profiles, the global settings gives you four options each for Battery and Plugged In. The top two options are similar in most cases and will generally run most applications on the iGPU, and the same goes for the bottom two modes where you’ll run most apps on the dGPU. The difference is that “Force Power Saving GPU” will run all applications (regardless of what the custom profile says) on the iGPU, essentially disabling the dGPU completely. “Optimize Power Savings” in contrast will run all unknown or “Based on power source” applications on the iGPU while respecting the application profiles where they exist. “Optimize Performance” is sort of the reverse of that, running all “Based on power source” applications on the dGPU while leaving unknown applications on the iGPU. Finally, the “Maximize Performance” option runs all unknown and “Based on power source” applications on the dGPU—but applications specifically set to use the iGPU will continue to do so.

The reason for that last discrepancy (e.g. why you can’t simply run everything on the dGPU and forget about the iGPU) is that certain tools have to run on the iGPU. Intel’s drivers are one example—loading those up on the dGPU would cause problems. Intel’s WiDi is the only other I could find on my particular Clevo notebook. We were told that some of the laptop utilities like an overlay showing percentage of brightness, volume, etc. may also need to run on the iGPU. Besides the few applications that have to run on the iGPU, any applications that are set to Power Saving will continue to use the iGPU—and this makes sense as there are a lot of applications that can be set to run on iGPU/dGPU that have no need of higher performance GPU options (several anti-virus utilities come to mind, where they're starting to create a 3D context for their UI). The net result is that other than a few specific applications where the profile will exist and be locked to the iGPU, with no option to change to dGPU, everything else that uses higher function graphics can be customized to run on a specific GPU, but if you set something to iGPU presumably you want it to always run there—otherwise you would use the “Based on power source” setting.

A full set of screenshots from all the driver screens is available in the gallery below if you’re interested.

One final topic worth discussing is Windows 8. Certainly there are owners of existing laptops with switchable graphics that are wondering if they can upgrade to Windows 8 and what will happen. We’ll have to see how this actually plays out, but it sounds like the earlier versions of PowerXpress (3.0 and earlier) will probably get support with one driver bundled with Windows 8, and that may be it—but there’s always the possibility for the laptop OEMs to release their own updates, or for AMD to roll out additional drivers for older laptops. The potential for PowerXpress 4.0 and later laptops to get regular driver updates (for Windows Vista/7/8) is there, but until we actually start seeing public driver releases AMD hasn’t fully committed to supporting all of those laptops.

    A lot of people, like myself, sold their previous gen laptops at discount prices so we could get the latest and greatest GPU. I sold mine for £800 (bought for nearly twice as much last year) and I've spent £1700 on this new 7970m based laptop, but sadly my old one outperforms it in several games. If I had known that there were these issues I would never had switched and if AMD were more honest about the nature of the issue I could had returned my card within the 30 day period.
    In my honest (and maybe somewhat biased now) opinion, i bought a faulty product because it does not perform as intended and definitely does not live up to AMDs marketing of being nearly twice as fast as 6970m.

    Hey Jarred. Nice update on the article in the conclusion. I personally don't mind utilization say in ME3 is only 35% if I have 60 FPS locked VS, that is fine by me. But what is concerning when I see I'm getting 80 FPS in Max Payne 3 with 95% utilization, but 5 minutes in, it drops to 45% and now only have 30 FPS in MP3. That happens in a lot of my games, it's very annoying. Reply

    I have always supported ATI and prefer their graphics. And it was the 6630M that finally drove me off.

    Would any of these improvement works on my 6630M? I think my Thinkpad E420 desperately need some drivers update.
  • JarredWalton - Friday, September 7, 2012 - link

    It looks like the ThinkPad E420 uses PowerXpress 4.0 (aka Dynamic Switchable Graphics), which means it should be supported with the driver release. I know I'll be trying the drivers on that old Sony VAIO C from last year as well. Reply

    Jarred do you know if this new driver is just for the lastest generation of AMD cards (and IB/SB graphics from intel)?
    Or can those who were unfortunate enough to buy a laptop with older AMD graphics (HD5850m) hope for a new driver (would be the first one since about 2 years -.-)?
  • JarredWalton - Friday, September 7, 2012 - link

    If you have a laptop with a 5850, you're probably not even running switchable graphics, right? Or if you are, it would have to be an Alienware solution I think. Anyway, for discrete-only GPUs, you should be able to download the Mobility Catalyst drivers already and update to 12.8 without issues. On the other hand, if there's some laptop I'm not aware of that had PowerXpress 3.0 and a 5850 GPU, you're probably out of luck outside of one launch driver update for Windows 8 (which would of course require you to upgrade to Windows 8...).

    PEOPLE post your game findings and GPU utilization, all problems and issues must be adressed if we want a more complete solution with the new drivers.

    Nice to see your article update Jarred, we are happy to see our commented concerns are being heard at last. I am rallying people to post their underutilization issues here so you might test more games and contact AMD more directly to show them were the BIG FAIL is.
    GPU underutilization is the key issue, most gamers wouldnt mind losing battery life if AMD can give them the option to use their cards to the fullest.
    In your own table one can see that some games run on very low %s GPU usage even at ultra settings (skyrim), wich would mean the NEW drivers in enduro 5.5 still need a lot of work on that department. Is also concerning seeing low utilization when lowering the graphics details and quality.

    THANKS again for all your work JARRED.
    So far you are the only light in a very black sky many 7970M owners are drowning under for months.

    Well, for the most part my CF 7970M setup works, but less than 10% of the time I see -some- issue, odd characters flying across the screen etc.

    And now I ran that Kombuster and saw that I was running on only 1 GPU. I don't recall ever having disabled CF, except for some testing a long time ago over at NBR.

    Catalyst control center doesn't even launch.

    Jarred, please pick this hot potato up, and bone AMD/ATI until we get resoultion with drivers. 13 pages of comments must show how upset people are...

    Thanks for a wonderful site.

    Over and out.

    Oh, man... don't even get me started on SLI and CrossFire notebooks. I would never actually recommend one of those -- the minor and major issues that crop up with compatibility and such are just not worth it. Thankfully, GPUs like the HD 7970M (assuming performance gets fixed) and the GTX 680M are now at the point where only seriously high-end gaming really needs more GPU muscle. If you want a 3D laptop, I suppose that's another use for dual GPUs, but I am not at all sold on 3D.

    Most likely, you'll have to go through Alienware to get new drivers, as they do some pretty custom stuff for switching graphics modes and what not -- but then I haven't played with that particular notebook so maybe not? First things first, though, you need to get drivers installed properly so that Catalyst Control Center will launch. Using hacked drivers probably isn't the way to go here; I'd grab the official Alienware drivers and see if you can bring up the control panel. If that works, then you can see about trying other unofficial drivers.
  • Notmyusualid - Friday, September 7, 2012 - link

    Apologies, for not being clear; it was not my intention to imply that I wasn't using AMD/ATI drivers, or that I was using hacked drivers.

    I was trying to shed light on the fact that Dell (Alienware) had not provided drivers for me, that work to any acceptable level.

    If I use the drivers from the Dell website, I may as well throw my notebook (using the term notebook loosely when referring to an M18X) in the river.

    Have a nice day.
