Simply put, Ridley Scott's 'Alien' looks phenomenal in high definition. The 1080p/AVC MPEG-4 encode (2.40:1) brings this sci-fi horror classic to Blu-ray with incredible detail, far better than anyone could have imagined for a thirty year old film. We can clearly make out the intricate design of the Nostromo's and the crashed alien spacecraft's interiors. Every distinct line in the metallic, claustrophobic halls, the mess hall, the air shafts, and all the computer gadgetry is made plainly visible. We can even see pores, wrinkles and small defects on the faces of actors while the alien's body reveals the hard work done by the designers. At times, the picture appears as though some digital noise reduction was used to clean it up a bit, but it's very mild and doesn't ruin the movie in any significant way. There is also a minor framing change (OAR is 2.35:1), but it's not drastic or observable unless one looks for it.
The film has always been dark with harsh, oppressive shadows, but delineation remains strong. Contrast is pitch-perfect, and blacks are often intense and deep, much better resolved with clean gradients than on previous editions. There are a couple moments with noticeably weaker resolution which take away from the brightness levels somewhat, like the scene when Kane wakes up in the infirmary. But for the most part, the image is consistent and beautiful. The palette is rather limited since more emphasis is placed on generating a brooding, ominous atmosphere, but the colors we do see, particularly reds, are rendered accurately and vibrantly. There is also another small change in color timing with a slight push on blue, giving the video a steelier, metallic appearance. Again, this is only noticeable if one wishes to carefully examine the differences, which honestly does nothing to spoil the film's enjoyment. All things considered, this high-def transfer of 'Alien' makes a stunning presentation on Blu-ray and remains the horror masterpiece it's always been. (Video Rating: 4.5/5)
Ufo Aftermath Higher Resolution Than 1080p

Just as its predecessor, this 1080p/AVC MPEG-4 encode (1.85:1) looks stunning and spectacular on Blu-ray, exhibiting plenty of natural film grain throughout. The picture shows astounding resolution and clarity in the clothing, weapons and exposes intricate, distinct lines in the architecture of the Hadley's Hope colony. Facial complexions display amazing lifelike definition and texture. Blacks are deep and penetrating, often rich while contrast levels are crisp and precise. The balance is so good, in fact, that early sequences in space can easily serve as demo-material for calibration purposes. Shadow details are also superb and revealing. Colors are deliberately limited, but accurately rendered, especially in the primaries, with strong variation in the palette.
Screen Percentage is a resolution scaling technique used to render a lower or higher resolution image than what is actually being presented. Being able to adjust the screen percentage enables your games to maintain a balance between performance and image resolution quality.
The Primary Spatial Upscale (or primary screen percentage) works by rendering the screen resolution at a percentage of the screen and then scaling it to fit your current screen resolution. Using a lower screen percentage (or lower resolution) and then upscaling it is called upsampling. Or, when the screen percentage is increased (rendering at a higher resolution), it is scaled down to your current screen's resolution, which is called super sampling. All of this takes place before the user interface (UI) is drawn and can have an impact on performance.
With Spatial Upscaling, anything drawn before the UI is at a lower or higher resolution based on the Screen Percentage used. The screen percentage has been lowered (indicated by the narrower render targets before UI), creating a lower resolution image for the render targets. Spatial Scaling happens before the UI, scaling the image to the screen resolution it will be output to. For example, if the current resolution is set to 1920x1080 and a screen percentage of 83% is used, the render targets will be resized to an approximate resolution of 1600x900 before being upscaled back to 1920x1080.
In addition to Primary Spatial Upscale, a second upscaling technique is also supported for the primary screen percentage: Temporal Upsample. Instead of performing temporal integration with the Temporal Anti-Aliasing (TAA) and then doing a primary spatial upscale, both happen at the same time in the Temporal Anti-Aliasing Upsample (TAAU) shader. It also allows them to converge to sharper images than what a spatial-only upscale could provide but comes at a higher cost since a larger number of post processes run at a higher resolution. It also allows for primary screen percentage changes to be hidden by dynamic resolution allowing it change more often to match the GPU budget as closely as possible.
Like TAA, Temporal Upsample comes with faster shader permutations for Post Process Quality 3 and 4. The shader permutations are traded against some amount of quality to ship a title at 60Hz on consoles. The quality settings are similar to what is already used when setting Post Process Quality. Also, keep in mind that TAAU needs more work than TAA since it runs at a higher resolution along with the post processes that follow the TAAU pass.
In addition to the Primary Spatial Upscale, there is the Secondary Spatial Upscale taking place after the TAAU pass. This can be problematic for high DPI monitors where the GPU may not be able to keep up depending on scene complexity rendered at the higher resolution. For that purpose, the renderer supports using a secondary screen percentage that drive the second and final upscale pass. This pass is independent of the primary screen percentage.
Adding the secondary screen percentage to your config file will override the Editor and any platforms it is set for. Also keep in mind that using the console variable r.SetRes controls the backbuffer resolution. It's best to leave that at 1080p or 4k so that the UI always renders at native resolution for the target platform.
Now, the resolution of the screen is controlled by Pixel Density. It removes the need to use "magic" numbers for screen percentages, making it easier to develope for multiple HMDs. By default, the eye views are going to be rendered at the HMD's recommended resolution to avoid the HMD compositor from doing any upscaling that normally is a cause of blurriness. You'll use the following console variable to give a higher or lower pixel density from the recommended resolution of the screen:
Of all the compromises that formed the Constitution, perhaps none would be more important than the compromise over the slave trade. Americans generally perceived the transatlantic slave trade as more violent and immoral than slavery itself. Many northerners opposed it on moral grounds. But they also understood that letting southern states import more Africans would increase their political power. The Constitution counted each Black individual as three fifths of a person for purposes of representation, so in districts with many enslaved people, the white voters had extra influence. On the other hand, the states of the Upper South also welcomed a ban on the Atlantic trade because they already had a surplus of enslaved laborers. Banning importation meant enslavers in Virginia and Maryland could get higher prices when they sold their enslaved laborers to states like South Carolina and Georgia that were dependent on a continued slave trade.
There's clearly something amiss on the PS3 side though, and the cause is twofold: resolution and Treyarch's choice of anti-aliasing method. We find the game hitting the same 880x720 figures enjoyed on 360 in places, but this isn't a constant throughout the game. Rather, it appears to be more dynamic than first thought, where several tests of the first level's river scene gives us a reading as low as 832x624. Scaling these resolutions typically produces more pixel crawl on PS3 as a result, and looks a world away from the sharpness what we're seeing on 360, which remains locked at its own resolution.
A resolution drop of this nature isn't enough to account for the excess blurriness on its own, however. What we think is a heavy post-processing technique is used to clear up the sharp edges, and some of its characteristics appear a match for the long-neglected quincunx AA available natively on Sony's hardware. As a result, Black Ops 2's edge-smoothing on PS3 is generally more thorough than rival platforms, even with the PC running at 4x MSAA in our captures. The downside to this approach is the heavy residual blurring to texture-work, plus the muddying of foliage elements in the background.
Above we have the game running maxed out completely. Much of the previous game looked barren at this higher resolution, but here we find plenty of details to justify the boost to 1080p. Alas, screen-space ambient occlusion doesn't have quite the effect we had grown to expect. Patches of shadow usually build up underneath moveable objects, such as corpses, but here we see little more than a self-shadow stretching across the ground.
But down to the crucial question: Xbox 360 or PS3? For the campaign playthrough there's a clear winner in Microsoft's platform, by virtue of its higher-resolution textures, superior shadow filtering, and its crisply scaled native resolution - sub-HD as it is - that looks closest of the two to the PC version's full 720p output. Sadly, the PS3 version's image quality suffers more than it should owing to its anti-aliasing technique, which blurs over an image operating with what appears to be a dynamic framebuffer. It's an unsightly combination that doesn't really pass muster, though the 1.03 patch appears to improve matters a touch.
I have now installed 3 rexing dash cams. For the price point and features have been very satisfied. The first 2 were the V1LG because it??s full of features but this time decided to go with the V1 gen 3 and test out the higher resolution camera 2ff7e9595c
