AMD’s Radeon HD 5450: The Next Step In HTPC Video Cards

HAWX
With everything but anti-aliasing and ambient occlusion enabled on HAWX, it’s playable at 1024 on everything at the GT 220 or higher level of performance. To get the 5450 to be playable, we needed to turn down the DX10 Sun and Shadow effects , which gave us enough power to be playable at 1280 without hurting the image quality too much more. Here the Radeon 4550 continues to win, while the GeForce 210 comes in a bit closer to the 5450 than it has in previous games.

[I got an error, so sorry if this is posted twice.]It's not overclocking at all. Powerplay is, as the poster above said, for power efficiency only. It actually doesn't overclock at all, but underclocks when the GPU is not being stressed.
If you're referring to one of the posts that requires you to enable overdrive, notice that it's only being enabled so you can stabilize the clock (and thus effectively disabling powerplay), but the GPU/mem are actually being underclocked by messing with an xml file and lowering the clocks manually via overdrive.

First of all, its not really a "audiophile feature" to get audio without droputs and other problems over HDMI, its devastating for the audio, no matter if you are a audiophile or not, secondly, powerplay is also used for power efficiency. The result is that HDMI audio doesn't work with default-setting for many people, this is a pretty major issue.AtW

already did, and it's the same with 9.11, 9.12, 9.12 hotfix, 10.1, and version 8.70RC2 (presumably 10.2 RC2).toyota - Thursday, February 4, 2010 - link
am I missing something? why are you saying Far Cry 2 benchmark cant go lower than high settings? all you have to do is select DX9 and you can choose low or medium from there.Ryan Smith - Thursday, February 4, 2010 - link
We stick to DX10 mode for benchmarking DX10-enabled games. In fact I never even tried DX9, otherwise I would have noticed that it goes lower.Humm...

well anybody trying to game on this thing will have to use whatever realistic playable settings are available. that means DX9 for Crysis/Warhead and Far Cry 2 would need to be used.andy o - Thursday, February 4, 2010 - link
That option has been there for a while, but there's no info on what exactly it does.Ryan Smith - Thursday, February 4, 2010 - link
Frankly, AMD has never documented it well. It has something to do with working with Windows MMCSS and DXVA to do exactly what the name describes, and that's all I know off-hand.It's aptly named though; I've seen a number of examples where enabling it does what's on the label.
