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

Batman: Arkham Asylum
Batman, as one of the least GPU-intensive games in our suite, performs well enough that we can run it above 30fps without turning down any settings. We have to run at 1024 to do it, but it means we can keep all of the visual splendor, just at a lower resolution.
The already small gap between the 5450 and the 4550 particularly narrows here, coming down to 1 frame per second. On the flip side, the 5450 once again underperforms the GT 220 by more than half the GT 220’s performance.

[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.
