Updated PureVideo Enhancements
PureVideo HD is a video engine built into the GPU of your graphics card (dedicated core logic). It allows for dedicated GPU-based video processing to accelerate, decode and enhance image quality of low- and high definition video in the following formats: H.264, VC-1, WMV/WMV-HD, and MPEG-2 (HD). Speaking more generic; your graphics card can be used to decode SD/HD materials in two categories:
HD Acceleration
The more your graphics card can decode the better, as it'll lower the overall used CPU cycles of your PC. We'll measure with the two most popular codecs used on both Blu-Ray and HD-DVD movies. VC1 is without a doubt the most used format, and secondly, the hefty, but oh so sweet H.264 format. We'll fire off a couple of movies and allow the graphics cards to decode the content; meanwhile like a vicious minx we'll be monitoring and recording the CPU load of the test PC.
HD Quality
Not only can the graphics card help offloading the CPU, it can also improve (enhance) image quality; as it should. So besides checking out performance of AMD's Avivo HD and NVIDIA's PureVideo HD video engines, we want to see how they effect the image quality, e.g. post-process and enhance the image quality of the movie.
Basically, in the entire GeForce Series 8 and obviously the new Series 9 range we see a 10-Bit display processing pipeline and also new post-processing options like:
- VC-1 & H.264 HD Spatial-Temporal De-Interlacing
- VC-1 & H.264 HD Inverse Telecine
- HD Noise Reduction
- HD Edge Enhancement
- HD Dynamic Contrast Enhancement
- HD Dynamic Color Enhancement
Today's newly added features in bold will be available for all GeForce series 8 & 9 products. With the GeForce 9600 GT comes the exact same VP2 decoding engine as found on the 8800 GT. You'll have your low-CPU post-processed, decoding 1080P image quality options with HD-DVD and Blu-Ray just like the 8800 GT with the new Video Processor 2 engine built in. I quickly verified; the HQV-HD score is at it's maximum 100 points and thus working like a charm.
Now read the topic carefully as with this new release we mainly talk about enhancements. In the upcoming drivers you'll notice the addition of two new features: Dynamic Contrast and Color enhancement.
It does pretty much what the name says; dynamic contrast enhancement technology will improve the contrast ratios in videos in real-time on the fly. It's a bit of a trivial thing to do, as there are certain situations where you do not want your contrast increased. Think for example a scary thriller, dark environment ... and all of the sudden your trees light up. So with that in mind; the implementation has been done very delicately. It does work pretty well, but personally I'd rather tweak the contrast ratio myself and leave it at that.
To the right you can see a screenshot where the new options are located, and yes sorry for the Dutch language.
** Here's an idea for NVIDIA's driver team, selectable languages in the ForceWare drivers.
The second feature is Dynamic Color Enhancement. It's pretty much a color tone enhancement feature and will slightly enforce a color correction where it's needed. We'll show you that in a bit as I quite like this feature; it makes certain aspects of a movie a little more vivid.
Also a small new addition for Vista Aero enthusiasts, previously when you play back a movie while utilizing graphics processor with software like PowerDVD, and thus had to shut down Vista Aero and revert back to the basic Vista theme; this has now been solved and windows transparency, thumbnail previews etc are all working as it's intended to do.
Also new is a feature called Dual-Stream decode. Pretty much it boils down to the fact that you can display two video streams simultaneously. Pretty handy if you watch a Blu-Ray movie with a small directors commentary window on the lower part of your screen.
Let's split the frames in two and compare with all interesting tweaks enabled. Two older features, edge enhancement and noise reduction obviously are also at your disposal. To the left the baseline (first) image, to the right the final result. Once we enable these as well and combine them with the Dynamic contrast enhancement and color enhancement option we see a distinct difference in image quality. Thanks to edge enhancement the frame is more sharp.
XFX GeForce 9800 GTX Black Edition review
A review on the XFX Black edition GeForce 9800 GTX, after reading some of you guys will probably will run to the store .. as the XFX XXX and Black editions obviously have fallen in price after AMDs Radeon 4850 launch.
XFX GeForce 9800 GX2 Black edition review
King of pre-overclocked products has to be XFX, their speed-bin of releasing OCed products is exceedingly fast. I do not think that there is an XFX product out there that is not available as a triple X edition or other series name slapped on top of it. Today will be no different, we received XFXes top of the shelf product, the GeForce 9800 GX2, the cool thing is that this is the new mystified named 'Black edition' series of cards, meaning it comes with a nice pre-overclock and an lovely game bundle.
XFX GeForce 9600 GT XXX 512MB review
A review on that XXX rated version of the GeForce 9600 GT. Hey, only XFX can implement such a name for you. XFX have a "way" of communication and getting attention. They quite honestly deliver really impressive products. Today's tested product is no different.
XFX GeForce 8800 GTS 320 MB Fatal1ty review
The Fata1ty Geforce 8800 GTS 320MB graphics card comes with it's GPU core pre-overclocked at 650 MHz and it's 320 MB memory clocked at (2x) 999 MHz. If that isn't rather radical, the Shader domain inside that graphics processor is clocked at a lovely 1620 MHz. Now if that does mean jack to you, these are the reference specs a 320 model normally has: 500 MHz core, 2x 800 MHz memory and a shader domain clock of 1200 MHz. Can you already sniff the performance increase ? That's like bacon on your eggs man.
