Tencent Digital News (Compilation: Rabbit) Before the release of PS4 Pro, most players heard the news of the so-called PS4.5 or PS 4K models. Many people are also looking forward to this new Sony console. Finally, the name of this host is named PS4 Pro, and the price of 400 US dollars (about RMB yuan), will be officially released on November 10. Although the PS4 Pro is still a PS4 in essence, if there is support for 4K streaming media and games, and some existing game masterpieces will be in the form of "patches", two versions of the Standard Edition and the PS4 Pro Edition will be released, while the PS4 Pro The version is mainly to improve the resolution, have a higher frame rate and improve graphic effects. However, overall, the PS4 Pro can bring the player's experience to a more limited extent. After all, it also requires the support of an extra 4K ultra-high-definition TV. However, at present, 1080p resolution has been able to meet the demand, so the PS4 Pro is for the pursuit of more. High quality player build. So what kind of experience will the new PS4 Pro bring? Is it worth upgrading? Let's take a look together. advantage 4K is impressive You may suspect that Sony's PS4 Pro's so-called 4K Ultra HD is the result of a special algorithm rendering, because in most cases, 4K game images are between 1080p Full HD and 4K Ultra HD, and then through a specially integrated algorithm Improved signal to 4K level. This may not be a standard upgrade, Sony's algorithms and special technical skills, basically can directly increase the signal source of 2K or even lower to 4K resolution level. So Sony's approach is also called "pseudo 4K" by Microsoft, but to be honest, most ordinary users should not see the difference he makes. Usually if your home TV size is less than 60 inches and the sofa is 3 meters away, the overall effect is still very good. So far, the two games, Call of Duty: Modern Warfare Revelation and Call of Duty: Infinite War, have already supported 4K resolution output and provided the most comprehensive experience to date. On television, we saw that the increase in resolution significantly increased the clarity. When people are moving, they no longer have a sense of pixels in their details, but they look closer to real life. In addition to high-speed moving characters, the texture of the surface is more delicate. In addition, in addition to the 4K picture enhancement, even if the standard 1080p resolution, PS4 Pro also improved a lot in the effect, in many scenarios the high-resolution model is more realistic, so for ordinary players, it is also One advantage, it seems that Sony's special algorithm can indeed produce a clearer image. Therefore, PS4 Pro really can not be called PS5, but on the basis of PS4, has carried on the overall enhancement to the original picture and definition. Compatible with existing games Since the PS4 Pro is not a brand new host, Sony has stated that any existing PS4 game can be upgraded by upgrading the Pro patch, which means that in addition to the 4K UHD resolution, Sony also offers the PS4 Pro. Added HDR effect. The HDR mode allows us to see more colors and higher levels of black, making the picture more vivid through the clear contrast of scenes. However, even if a game does not get the PS4 Pro upgrade patch amendment, the original game can still run on the PS4 Pro, but the resolution and frame rate are maintained in the original PS4 standard. Silent The PS4 Pro is quite quiet and doesn't have a lot of noise. Before, my PS4 can be said to be the most noisy device in the home. The sound of the optical drive and the fan running at the same time often gives me the illusion of taking a "helicopter". On this point, whether it is my PC, Xbox One or Xbox One S is much stronger than the PS4. The PS4 Pro seems to have progressed a lot in silence this time, and it can even be compared with the Xbox One S. This may be because the PS4 Pro uses the latest AMD Polaris architecture graphics card. The graphics card uses a 16nm process, so the heat is lower and the power is smaller, so there is no need for too high power fan cooling, and in most cases The PS4 Pro is very quiet. Virtual reality games run more smoothly Sony not only improved the picture and quality of the game on the PS4 Pro, but also provided a more fluid experience for PlayStation VR players. In my tests, I experienced higher resolution and image effects, so in a game like DriveClub VR, the screen looks more realistic and the overall details are more perfect. This is also a lot better than the PS4. . PS4 Pro makes PlayStation VR's overall performance comparable to PC platform VR devices such as HTC Vive and Oculus Rift. Sony should ensure that the compatibility between PS4, PS4 Pro and PlayStation VR will be further improved in the future. insufficient High demand for television The current 4K ultra high definition television market is in fact a mess. When 1080p was still the mainstream of the market, major TV manufacturers began to madly render 4K ultra-high-definition concepts, but the products were good or bad, and no one at the time had experience. So if you test with the PS4 Pro now, you will find that your home 4K TV may not be able to fully play the PS4 Pro's performance. And most importantly, if you want to fully experience the effects of the PS4 Pro, the TV not only needs 4K resolution, but also has to support HDR. Although not all HDR TVs support the latest HDR10, this certainly cannot make the PS4 Pro perform its best. Whatever the reason, you will miss out on a PS4 Pro feature. Unless you spend a lot of money to buy a flagship 4K TV, you can only cooperate well with the PS4 Pro, or even if you upgrade the PS4 Pro, the effect is not satisfactory. Of course, some entry-level TVs also support the UHP standard, and this is also a feature compatible HDR10, you are lucky. However, it can be said that televisions in most ordinary consumers' homes should be just ordinary HD levels, and if a high-end UHD TV is to be sold, the price should be at least 1,500 US dollars (about 10168 yuan). PS4 can actually HDR Even if you have a HDR10 standard TV, you don't necessarily need to use PS4 Pro. In fact, Sony has said that the PS4 can also be upgraded to get HDR effect support. In fact, compared with 4K ultra high definition, HDR must have a more impressive effect. After all, at a distance of more than 3 meters from the TV, it is difficult to see changes in the pixels. But more varied and more accurate colors can immediately attract our attention. Therefore, since the PS4 can also be upgraded to obtain HDR effect in the future, why should we pay extra for the PS4 Pro? Does not support playback of 4K Ultra High Definition Blu-ray Discs If you never read the CD, then this will have no effect on you, but if you are an audiophile besides the game player, then the PS4 Pro does not support Ultra HD Blu-ray Disc playback. Fortunately, we can experience 4K streaming content from Netflix or the PlayStation Store, and these streaming videos are no less effective than Ultra HD Blu-ray Disc. to sum up We can simply talk about suggestions. PS4 Pro is priced at 400 US dollars (about 2711 yuan), if you did not previously Sony's game console, then PS4 Pro is a good choice. After all, compared to the PS4 Slim, although it costs more than 100 US dollars (about 660 yuan), but in the picture quality and resolution and performance have greatly improved. After all, the game development in the next two or three years must be considered now. PS4 Pro is much better than the PS4 released in 2013. However, if you are already a PS4 owner, then I suggest that you do not act rashly unless you are Sony Iron Powder or have special needs for games like PlayStation VR. Otherwise if you don't have that much money in your pocket, or if you don't feel bad about virtual reality games, then I suggest you wait for Sony's PS4 upgrade to see how it works before making a decision.
