Why doesn't PC use disc as game carrier like xbox, PS4
It has to see in two aspect,On the one hand is the limitation of the technology of optical disc, on the other hand is the development of the computer.
The limitation of the technology of optical discIn fact, whether you want to admit it or not, the technology of optical disc is already a backward thing.Now there are several problems with the disc, one is the reading speed.
Both the next-generation consoles ps5 and xbox use solid-state drives, obviously because everyone realizes that the increase in reading speed will break the bottleneck of free online game production.Sony also emphasized in its hardware description that faster disk reading speed will fundamentally change the production of modern games,For example, Spider-Man can swing faster. Correspondingly,Is it possible to fly or jump if there are characters in other games, such as Batman's gliding wings, can it be done more smoothly than now.There are also some scenes such as riding an elevator in the games. In fact, it is to save time for the game to load the scene. If the hardware reading time is accelerated, then these scenes can also be saved in theory.However, the reading speed of the CD-ROM is really can not comparable to the solid-state hard disk, this is the shortcoming of the CD-ROM.Now game consoles still use discs because of the industry chain accumulated over the years.and also also formed a habit,So the solution of the game console is to use the CD as a carrier, buy it back and put it in the host, and then install it on the hard disk of the host.This has been tried from the previous generation. Due to the problem of reading speed of Blu-ray discs, the ps3 generation will also copy part of the content of the disc to the hard disk of the host, and then play the game.
Although it was not copy of all, but you can see the trend, until this generation, basically all the contents of the disc are copied to the hard disk to play.The disc has existed as a verification object after the first copy. In theory, the content of the game you are playing is already on your hard disk.
Another limitation of the disc is capacity.Although the capacity of the last generation of Blu-ray reached 25 to 50G.At that time, many developers complained that such a big one could not be used up, but today it is true that it is not enough totally.With the development of game development technology, the flow of games, the high-definition of materials, etc., all make the capacity of the game larger and larger.now,a 50G Blu-ray disc is really not enough.There are currently two methods to solve it.One is to put a part of the content on the CD, the rest is solved by downloading.Light adventure is like this :The stand-alone part is placed in the CD, and the network part needs to be downloaded additionally.Another method is that use multiple discs.
The second method will appear at the end of the host,ps host using cd disc and ps2 uses dvd as a carrier but There also has the problem of insufficient capacity leads that there are so many games have this problem.
However, at that time, optical discs were still developing, so some people were willing to develop larger optical disc technologies.however,now it has gradually failed to keep up with the needs of the times,it is hardly to say will there be this technology in the future?It is not that our technology can no longer develop a larger disc technology, but that it is not necessary from a practical and commercial point of view.
The development of computer games
The development of computer games also determines that computer games no longer use compact discs as the carriers,The biggest reason is piracy,The history of fighting against pirated games is very long,In order to prevent pirated computer games, there have been various patterns,such as setting a puzzle in the game,and the answers to the puzzles are on the first few pages of the original manual.Later, there were anti-cracking technologies, some of which even interfered with users' normal use of their computers,
In fact, carriers such as optical discs are not good at preventing cracking.With the development of the platform such as steam,Genuine computer games are more friendly than CDs in terms of price and ease of purchase,
In addition, due to the reason of piracy, computer games have not formed such a huge disc system for game consoles, and users have not been form a habittde to use solid disc.so it’s easy that carry the disc as a carrier, and it is easier to cultivate the habit of users to use the digital version of the game in the PC game.
Therefore, computers also used discs, but due to piracy problems, this market has not formed a scale, and users have not formed a solid habit, lead that digital platforms is easily to replaced by disc games.
