Oh and I heard that the display driver 9.00 works really good with 7 series cards

[Subhadip]

AMD is releasing official Windows 8 RTM drivers on 16th August. Should be known as Catalyst 12.8 WHQL. Till then the 9.00 leaks seem to work rather well with RP. Definitely getting a couple of frames extra versus Windows 7 on the same driver.

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.

The leaked AMD 9.00 drivers work perfectly on my 6990 4GB. For more leaks and other drivers that may work for you, check out: http://forums.guru3d...isplay.php?f=46

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

Got around to installing the RTM and decited to add my two cents to this; I have 2500k, 8Gigs of RAM and a 4890 and overall I get more or less the same performance except in BF3 where it's noticeably worse than in Windows 7.
Where I'd get about 60 frames per second in 7, it drops down easily to 40 in 8. I play on low/med settings at 1280x800.

I had the same experience in the RP and was hoping to see some improvement but it's the same.
Probably due to the fact AMD decided to drop continuous support for series 4000 and under. Shame since my 4890 can still hold its own in new games.

Using these on Win 8 Enterprise x64 with 7970s and 7870. Great performance so far. These were just released today.

I'm currently installing Battlefield 1942 (yes, incredibly old school) just to see if it runs. The more I use this OS, the less I like it.

Gonna assume you were talking to me. As I said, AMD isn't going to support legacy cards, which the 4000 now falls into since a couple of months, the latest stable release for my card is 12.4, which worked fine in Win8 but didn't help with the performance issue.
Same with the 12.6 Legacy beta drivers.

I'm guessing the issue is related to DWM which can't be turned off, as another I play (Osu!) as input lag- exactly the same way as when I play in windowed mode with DWM enabled.
It's not AMD's fault though; it's just how Microsoft decided to do things with Windows 8. Not gonna blame them either, my card is several years old, it doesn't affect anything else, only high end games (and Osu! for some reason...).

Will probably upgrade one of my PCs when AMD will, if ever, get better "legacy" drivers via WU out.

well im running on 12.8 Catalyst Driver and it is soo smooth on battlefield 3 (48-52fps Consistent) 1680x1050 all high motion blur off, Counter-strike Source I get around 250fps consistent starcraft 2 120fps all high settings 1920x1200 runs so amazin no rendering lag I load before everyone on a 4v4 match just cause 2 max settings 60fps with vsync on and that's all I have tested the best about the OS is no frame rate spikes constant smooth rendering of graphics and boot times on applications such as origin, steam, battlefield and other games load nearly instantly

Im running:
AMD 1100T x6 3.3Ghz
ATi 5750 1GB GDDR5
8GB of ram
and a normal HDD 1TB

im really impressed with this OS only little downfall is file transfers but that's okay cause it scans you're files for viruses before saving

The more I use Windows 8, the more I like it. My games all seem to be working quite well.

[GP007]

Performance problems could be, and probably are a cause of the change in WDDM. If I remember correctly, Windows 8 uses a newer WDDM version, 1.2, compared to v1.1 in Windows 7. The, probably minor, changes they've done are what's messing with older drivers. This sucks for older 4000 card owners on the AMD side, but, guys, if you can upgrade it's worth it. I upgraded from a 4770 to a 5770 last year. I'll upgrade again to whatever the newest AMD card is after I do some other upgrades to this PC and finally install Win8 RTM on it.

[Dashel]

I've seen zero performance gains and several net losses, I'll chalk that up to drivers for now. I'm just not seeing this 'radical' performance jump compared to Win7, in anything but boot times. I'm suspect of anyone that says they can perceive a 5-10% gain unless their hardware is already borderline.

Little report about running the newest games on Windows 8:

FIFA 13: Doesn't run smooth, gets random lags. (The game runs perfect on Windows 7)

PES 13: The same problem as the FIFA 13, but a little bit smaller lags. (Runs perfect on Windows 7)

F1 2012: FPS drop. The car is getting to vibrate, when you're close with the other cars. (No problems on Windows 7)
Av. FPS = 58.8, Min. FPS = 53.3, Samples = 8615 (Windows 7)
Av. FPS = 57.1, Min. FPS = 46.9, Samples = 8372 (Windows 8)

I was readed some good benchmarks of windows 8 vs windows 7 gaming performance, but in my pc is not the same story.
Maybe, the fix for this problem is to wait for a new version of NVIDIA drivers.
