I assume they're blocked as the release drivers are newer. I don't have it so can't verify, but it seems logical.

Hang on, are you saying there are RTM drivers? I didn't see any....

Tried installing an older version but the catalyst install manager simply didn't even show the option to install drivers.

I managed to get the VISION centre app installed but it only showed power options for my cpu (and clock speed stuff) none of the usual graphics stuff.

I see your problem. You have an AMD card. :shifty:

Har har har. I actually really love it. Some people stick with a single brand, I've switched between nVidia and AMD (well, ATI) several times now, always getting the best bang for buck. And no, (when I can actually get) drivers, I don't have any problems at all with them and haven't done for years.

I just did some gaming on Windows 8 RTM using an AMD 6950 and the default RTM drivers. BF3 was smooth, just like it was under Windows 7. It had a few hiccups though. It would have periods of smooth, with a few freezes. Then eventually the game got so slow I had to quit. If you have an AMD card, I think this might not be a good idea right now. I have a machine with a GTX 680 in it, reluctant to go to 8 right now on that one though.

Hard to tell currently as most of the Windows 8 drivers including both the NVIDIA and AMD Catalyst are in Beta.

However overall we expect noticeable performance improvements including in graphics/gaming because Windows 8 can handle a lot better the existing hardware and its a "lighter" OS from Windows 7.

I said I assume. I won't have the OS til October o.o

Performance is definitely improved over Windows 7 and 8 RP.

And this is why you should wait for a couple of months to install Windows 8 as your main OS ;)

Indeed, this is why it is not on my 680 GTX machine. Though with Windows 7, as soon as it became RTM, it worked pretty well right away. I guess because Windows Vista drivers worked with 7 pretty darn well.

AMD dropped support for anything below 5xxx series for W8. No bang.

NVIDIA created unified drivers, like a boss. They still support really old GPU with W8. Bang.

They're still supported with the launch drivers, which are probably still many versions past anything that actually made a difference for those cards.

In short, everything in Windows 8 is hardware accelerated, and as a result its text, 2D, and 3D performance will blow Windows 7 away. DirectX 11.1 has also received a significant overhaul that should result in faster and more efficient games and applications. The bulk of the graphics changes in Windows 8 pertain to hardware acceleration for simple, typographically-rich Metro-style apps. In Windows 8, the rendering speed of text and simple shapes has been massively increased across the board: Title and heading text renders 336% faster than Windows 7; Lines render 184% faster; Rectangles render 438% faster; and so on. The rendering of JPEG, PNG, and GIF image files has also been improved in Windows 8, mostly by expanding SIMD usage. In one demo, Windows 8 decodes and renders 64 JPEGs in 4.38 seconds, while Windows 7 performs the same task in 7.28 seconds. Amongst a few changes to DirectX, the most significant feature in DX 11.1 is the new, simplified, unified Direct3D 11.1 API, which finally brings together the many API offshoots that MS has implemented in recent years.

well, this is good right? I'll watch the next weeks benchmarks and maybe I'll jump to Win 8 and happily ignore the Metro fail.

I bit the bullet and installed it on my machine with the GTX 680. Much better experience. Beautifully quick. From the looks of things, I am about 8 FPS faster with the same settings.

I wonder if I can use windows 7 drivers for my 6950 machine in the meantime.

proofop.jpgI am running windows 8 Professional x64 RTM with AMD Display Driver 9.00 w/ ATi 5750 that installed perfectly on windows 8 RTM and I installed battlefield 3 the first time boot up in windows 8 took no time at all 5 seconds to fully render all the graphics and let me select my class. it is such an amazing operating system consistent Frames per second I get roughtly about 35-50FPS(windows7) windows 8 (48-52FPS) consisntent cause of my video card some dense places on the map were a tad laggy (hence no polished AMD drivers yet for 8) but ive used every build of windows 8 and it only got better.

When I played Battlefield 3 all my settings were set to high motion blur off AA post low and no AA ran with no fps lag at all! :)

Also im about to play crysis 2 with the dx11 patch and (windows 8 system sounds are beautiful ^^)

and im here to help you AMD users out cause well AMD is the BEST! :D

here is the display driver im using right now and its flawless in gaming. thought ive ran into a few black squares in StarCraft 2 but it disappears almost right away.

http://depositfiles....files/kkd8sr41y - AMD Catalyst + Display Driver 9.00 goodluck have fun :)

Performance is better all around for me on my GTX680 machine. One thing that is odd is I had to turn HT on on my 2600k (4.6ghz OC) or else I get near 100% CPU usage playing BF3 which results in hitching and severe FPS drops. CPU spikes also when using the Slingplayer windows app. Wondering if these will be fixed.

I do not even know why this is happening, but one of the more demanding games that are ran by the Unreal Engine 3, for example Batman: Arkham City, performs way much worse on Windows 8 than on Windows 7. I doubt it's even because of the graphics card driver, since the entire game is performing slow in all areas.

So I'm not getting only slow framerates, but also cracking sound, excessively slow gameplay, and a few more. It literally feels like running 1 frame per each second :p

    • US citizens are paying to their government, who could use that to fund healthcare and tuition and relieve the costs of these for citizens instead of making tax breaks that overwhelmingly favor the rich. I'm not saying that tariffs are the correct solution, but what else would they be used for? What else could Trump have in mind for wanting them, if he hasn't figured out that labor costs are higher in the US?
    • I’m in need of a new chair and it sounds like the backrest cannot be locked? I also sat on a Herman miller and was devastated that it couldn’t be locked also, what is going on with chairs. I want to be able to lock the backrest into any position but not even the Herman’s do that
    • Sihoo Doro C300 Pro V2 Ergonomic Office Chair review: The Ikea of chairs by Steven Parker I've reviewed a few gaming chairs over the past three years or so and generally found them to score well in our reviews. SIHOO reached out asking if I was interested in taking a look at their flagship chair, the Doro C300 Pro V2. I never got the chance to check out its predecessor, but the V2 is described as an "Adaptive Ergonomic Chair." It became available to buy in April of this year. Let's get things rolling with a closer look at the specifications and features. Specifications Doro C300 Pro V2 Model Ergonomic Materials Mesh Back and Seat; Soft PU Coated Armrests Height adjustability 45.5 - 53 cm / 17.5" - 20.9" Seat (w+d) 52 x 43 - 47 cm / 20.5" x 16.9" - 18.5" (adjustable) Backrest 52 – 60 cm / 20.5" - 23.6" (adjustable) Lumbar support Mesh built-in (adjustable) Armrest adjustability 8D Bionic Armrests Rocking angle 105°, 120°, 135° (fixed) Neck support Mesh built-in (adjustable) Net weight 27.3 kg / 59.64 lbs Weight support 150 kg / 330 lbs Colors Black, White Warranty 5 years (upon registering) Price $499.99, $539.99 Introduction At first glance, it looks like a chair that in another life wants to be a Herman Miller; It certainly looks like my Aeron Remastered, but the Doro C300 Pro V2 has quite a few more features and costs quite a bit less. SIHOO says that it is made up of a "DynaCore" system that tracks your movement and synchronizes the headrest, backrest, lumbar support, and armrests as you shift, twist, or recline. They also say that the "SyncroFlex Backrest" molds to your spine, which kind of describes how the mesh fabric works in most ergonomic chairs, but anyway. Below are the meat and potatoes measurements for the chair. Here is the same tech sheet, but in inches. Durability I would be remiss to not talk about the various durability testing this chair underwent before coming to market, as this is claimed on the product page. First of all, the chair is BIFMA-, SGS-, and TÜV-certified. As for durability, the tests undergone were: 100,000 Castor cycles tested 120,000 Armrest cycles tested 120,000 Recline cycles tested 120,000 Gas lift cycles tested 60,000 Armrest durability cycles tested 120,000 Rotation cycles tested Nothing about weights testing, though. Now that's all disclosed, now onto my own personal findings. Assembly The Doro C300 Pro V2 came in two large boxes (1) (2), and everything was packed very well, protecting the different parts of the chair. In the box, there is a folded sheet that explains the 12 steps to assemble it; they are: Remove the bottom cover on the aluminum base; Insert the five legs into the aluminum base and use ten screws to fasten them; Insert the castors into the legs; Replace the bottom cover on the bottom of the aluminum base; Place the Class 4 Hydraulics gas cylinder into the aluminum base; Screw the bottom part of the arm rests, taking care of the orientation using two screws on each side; Use three torx screws to fasten the footrest to the bottom of the seat; Fasten the backrest to the seat using four torx bolts; Fasten the armrests to the backrest using four Torx bolts (two on each side), taking care to note the orientation; Place the chair onto the Class 4 Hydraulics gas cylinder; Insert the headrest into the top of the backrest; Use two torx screws to fasten the headrest to the backrest. There's also an online guide you can refer to. Carefully unpacking the two boxes took around 15 minutes because almost everything is wrapped in plastic and protective foam; the chair assembly itself took around an hour. I say in the above assembly steps to take note of the orientation, because it's not obvious which way around the bottom portion of the armrests go, and although there is an L and R on the bottom of the armrests, it also wasn't clear from the instructions which was actually left or right, facing the chair, or in the seated down orientation? Anyway, I ended up putting the bottom portions on the wrong sides, and after securing one of the armrests, I discovered that although it was on the correct side, the armrest base could rotate a full 360°, but not when bolted to the chair, so I had to remove it, rotate it, and then bolt it back on. Truly an Ikea experience! Also, to complicate things further, although all the parts are labeled from A to X (yes, that's 24 parts) unhelpfully, these letters do not appear on the parts themselves or the package with the bolts, screws, and washers. There's also a pair of protective gloves in the box, but I think they were made for much smaller hands than I have. Even my friend, who is 5.1, had difficulty putting them on. Once assembled, I needed to sit down. Anyway, as I said, it looks quite similar to my Herman Miller. And here is the back of it. If you look at the product page and on Amazon, it seems like a lot of thought has gone into the chair itself and what it's capable of, but there is no mention at all about the castors, and this is an area where I think the chair trips up quite quickly. I found it difficult to move the chair in any direction. I asked a friend who came to visit me earlier this week to test my findings, and she said that the wheels were "no good," so it definitely isn't just me. I am 6'2 myself and a big guy, I work from home and gained a few pounds from mostly staying in and the hell away from other people. However, the Doro C300 Pro V2 is rated for up to 150kg (330lbs), which in my case is used well within its max rating. Ergonomics The number of adjustments you can make, right up to setting it in nap mode — which I haven't fully tested yet — is what you'd expect from a premium chair. Yes, you can go up and down (max 7.5 cm adjustment), rock back and forth (with tilt adjustment), and lock the chair between three stages of 105°, 120°, 135°, which is not quite as flat as the AndaSeat I tested at 160°. Some thought has also gone into the "8D" armrests, too, which are cushioned but quite firm; you'll only know it if you press hard into the PU-covered tops, which give about half a centimeter, but it's enough to ensure your skin won't get awkwardly stuck to it in warmer (or sweatier) conditions. It almost feels like plastic and is very easy to keep clean. However, the armrest positions move far too easily, and I am not sure what that "elbow" function is. Maybe it is good for a short person with short arms, anyway, I never used it and kept it flat at all times. There are eight levels of adjustment for the armrests, they are: backwards, forwards, swing left/right, height up and down, tilt, and 360° rotation, which can be handy for desk clearance. As I said, the armrest pads shift far too easily, which could give off an ergonomic vibe, but who wants the armrest sliding when you are shifting weight? The height adjustability does lock into place when lifting and adjusting. Comfort This is ultimately what it boils down to at the end of the day, right? Quite a lot of reviews praise the comfort of this chair, and I don't disagree that the mesh seating is quite comfortable. I am used to the material from my daily Herman Miller. However, the backrest cannot be locked into place, and this is actually a feature; as you shift or recline yourself on the chair, the backrest moves with your body. It took some getting used to. The lumbar gives ample support, but I would have preferred an adjustable one built into the seat base, as this causes the backrest to move up and down at will. Again, as with my previous chair review, this chair is also rated for tall people, but nowhere in the product documentation does it say how tall. Being 6'2 myself, I'm happy to say that the backrest is tall and wide enough, and thought has been given to being able to adjust the neck rest, but as others have mentioned in their reviews, people as tall as 6.2ft is about the limit for the neckrest. Conclusion What I didn't like The footrest is rated for 15kg (33 lbs), which to me seems a bit light, and after looking online, it seems like a chair footrest for adults must be at least twice that rating. In all honesty, they are just hollow metal tubes, so it is not recommended to let a kid sit on them. I also feel like it doesn't really go out far enough for my height, so that kind of puts the dampener on me being able to use it regularly. I'll just have to continue to use my subwoofer as a footrest! I do not like the armrests being able to shift around as easily as they can, and they are a little too forward-positioned in the chair to comfortably sit close to my desk, because even in the lowest height position, they don't allow me to go under the desk like is possible with my Herman Miller. I also feel like this chair could have been delivered partially constructed, especially the armrests on the seat, and why the aluminum base wasn't already pre-constructed (without the castors) is baffling, considering it would have fit in one of the two boxes that way. The instructions also need to be clearer. On the pamphlet, there's an A to X listing (which is also used in the steps), but none of the physical parts use this lettering system! What I did like I'll be honest, I haven't used it for very long, just one week, and seating comfort is subjective after all! Any spills wiped straight off it, the stitching, and the lines look great, not a fray to be seen or stitch out of place. It looks kind of cool, too. My favorite feature of these seats is the nap mode. While you're not lying completely flat, it leans far back enough to make you easily doze off after a heavy gaming or working session. Overall, this chair offers plenty of comfort features. The MSRP does vary quite a bit depending on the region, at £549.99 in the UK, and €580 in Europe, and $599 before tax in the U.S. However, shipping is free, which is a bonus for such a heavy item. Is it worth it, though? At three years' warranty, I think it's a decent deal. Another firm out of Germany sent me a free replacement hydraulic gas spring for a chair that failed after almost four years, so it was well outside its two-year warranty. My advice is to always try, as you might have the same luck I did. If I could fault it at all, it would be the constant shifting of the armrests and backrest. Where to buy Although the footrest variant normally costs $539.99, it has been discounted to $469.99 on the official website in Black or White. In fact, the non-footrest variant is only $40 cheaper.
