(PlayStation 4)当谈到新的PS5游戏机时， PlayStation 4游戏玩家有很多值得高兴的地方。它不仅是下一代强者，而且向后兼容几乎所有PS4游戏。
提供的不仅仅是香草PS4体验。将您的PS4(PS4)游戏升级到PS5时有多种选择，以便您可以在新游戏机上玩它们。我们将研究所有可能的改进以及如何访问它们。
(PS5 Backwards Compatibility)简而言之(Nutshell)PS5向后兼容性
让我们快速回顾一下基本的PS5向后兼容性细节。您可以在我们的PS5 向后兼容性指南(PS5 backwards compatibility guide)中获得更完整的讨论
要知道的最重要的细节是，除了非常短(short list)的PS4游戏列表之外，所有游戏都可以在PS5上运行。无论您使用基于光盘的游戏还是数字下载，这都是正确的。PlayStation 3、2 和 1 游戏现在是不可能的。没有人知道索尼(Sony)是否会增加对这些系统的标题的支持。
固有的 PS4 游戏升级
有一种游戏升级是在PS5硬件上运行游戏所固有的。首先，在(First)PS5上运行PS4游戏可以消除PS4或PS4 Pro上可能存在的任何性能问题。比如那些游戏对PS4(PS4)硬件来说太多，导致帧率下降的时候。
现代游戏，包括来自后期PS4的游戏，通常具有解锁的帧速率和动态分辨率缩放。像这样的游戏从PS5(PS5)硬件中获益最多，它可以简单地扩展到游戏支持的最快帧速率和最高分辨率并保持在那里。
在某些游戏中，例如《最终幻想 XV(Final Fantasy XV)》，您需要在游戏菜单中选择解锁帧率的模式。因此，请检查您是否需要调整游戏内设置以让PS5稍微伸展一下腿。
游戏加速升级
您可以为您的PS4游戏获得的下一种免费升级是PS5 Game Boost。这是PS5的一项功能，仅适用于有限数量的经批准的PS4游戏。PS4游戏必须通过Game Boost验证。但是，由于Game Boost(Game Boost)列表和设置已内置于系统软件中，因此您无需执行任何操作，只需让系统软件保持最新状态。
当在您的PS5上运行与Game Boost兼容的PS4游戏时，它将受益于控制台的额外性能。
带有免费 PS5 版本的游戏
到目前为止，我们只介绍了被动的PS4升级，这些升级实际上不需要您做任何特别的事情，除了让您的系统保持最新并安装相关的PS4游戏。但是，某些PS4游戏也有PS5游戏版本。
这是两个独立的游戏，并且在店内会出现在不同的游戏盒中。但是，一些开发者会为任何拥有PS4版本的人提供免费升级。是否提供PS5版本的游戏作为免费升级完全取决于开发者。如果您正在考虑购买PS4游戏并希望获得PS5版本，则必须根据具体情况确认是否有资格免费升级。
在撰写本文时，确认有少数游戏可以免费升级PS5 。一些，如无主之地 3 和食(Maneater)人者已准备就绪。其他游戏，例如《巫师 3(Witcher 3) 》和《赛博朋克 2077(Cyberpunk 2077) 》 ，将在未来进行升级。因此，对于《赛博朋克 2077(Cyberpunk 2077) 》这样的游戏，您现在可以毫无顾虑地购买PS4版本，并在(PS4)PS5版本上市后立即免费获得。以下是免费升级的著名游戏列表，但这不是完整列表：
- 刺客信条瓦尔哈拉
- 无主之地 3
- Control Ultimate Edition（其他版本不免费升级）
- 赛博朋克 2077
- 命运2
- 污垢 5
- 毁灭战士永恒
- 孤岛惊魂 6
- 食人者
- 蜘蛛侠：迈尔斯·莫拉莱斯
- 仁王 2
- 无人深空
- 巫师 3
- Yakuza: Like a Dragon（仅限数字版）
您会注意到某些游戏，例如Yakuza，仅提供数字版本的升级。因此，请在购买之前检查给定游戏的光盘升级资格。
升级光盘游戏
在您问之前，如果您购买了没有光驱的PS5 数字版(PS5 Digital Edition)，则根本无法玩或升级您的PS4光盘游戏。如果您有无盘PS5，请跳至下一部分。
要将符合条件的PS4光盘游戏升级到PS5，您需要完成几个步骤：
- 首先，确保您已使用自己的帐户登录。
- 现在，将PS4 游戏光盘( PS4 game disc)插入 PS5 的驱动器。
- 现在，转到游戏的游戏中心(Game Hub)。
- 将提供升级优惠，可以免费提供，也可以打折提供。
- 选择下载(Download)或支付折扣费用(pay the discount fee)，然后下载游戏。
兑换升级并下载游戏的PS5版本后，唯一需要注意的是，只要您想玩PS5游戏，就需要将(PS5)PS4光盘放在驱动器中。
升级数字游戏
如果您想为PS4升级您拥有的数字游戏，那就更简单了。您不必担心无法访问PS4版本的游戏。我们能够在 PS5 上同时运行PS4(PS5)和(PS4)PS5版本(PS5)的游戏。如果您选择保留您的PS4 ，您也不会失去对 PS4 的访问权限。这是做什么：
- 在 PS5 上登录您的帐户。
- 打开PlayStation Store并前往 PS5 版本游戏的游戏中心页面(game hub page)。
- 您会看到PS5(PS5)版游戏的升级优惠或折扣价。
- 选择下载(Download)或支付折扣价(pay the discounted price)，然后下载游戏。
下载游戏后，您只需从游戏库中启动它即可玩。就是这样！如果您在下载PS5版本之前已经在系统上安装了(PS5)PS4版本的游戏，您可以将其删除以节省空间。
升级到PS5(Cons)版(PS5 Version)游戏的利弊(Pros)
虽然将您的PS4(PS4)游戏升级到PS5版本似乎是双赢的，但实际上也有一些缺点。需要明确的是，接受升级报价本身是非常好的。只是PS5游戏有一些PS4游戏没有的限制。
首先(First)，PS5游戏只能从内部SSD玩。只有大约 667GB 的可用空间并且现在无法备份游戏，这是一个非常有限的资源。PS4游戏可以从任何支持的驱动器运行，包括大型外部驱动器。
它们不像原生游戏那样受益于令人难以置信的快速内部SSD技术。(SSD)如果您想在不占用内部SSD存储的情况下获得(SSD)PS4游戏的最佳加载性能，我们建议使用 USB SSD 驱动器(SSD drive)。
How To Upgrade PS4 Games To PS5
PlayStation 4 gamers have a lot to be happy about when it comes to the new PS5 console. Not only is it a next-generation powerhouse, but it’s backwards compatible with virtually all PS4 games.
It’s not just the vanilla PS4 experience that’s on offer either. There are various options when it comes to upgrading your PS4 games to PS5 so you can play them on your new console. We’re going to look at all the improvements that are possible and how you can access them.
PS5 Backwards Compatibility in a Nutshell
Let’s quickly go over the basic PS5 backwards compatibility details. You can get a more complete discussion in our PS5 backwards compatibility guide
The most important detail to know is that all but a very short list of PS4 games work on a PS5. This is true whether you use a disc-based game or a digital download. PlayStation 3, 2 and 1 games are out of the question right now. No one knows if Sony will ever add support for titles from those systems.
Inherent PS4 Game Upgrades
There’s a type of game upgrade that’s inherent to simply running the title on PS5 hardware. First of all, running PS4 games on a PS5 removes any performance problems that may have existed on the PS4 or PS4 Pro. Such as those times when the games were too much for the PS4 hardware, which caused a drop in frame rate.
Modern games, which includes those from the later PS4 generations, often have unlocked frame rates and dynamic resolution scaling. Games like these benefit most from PS5 hardware which will simply scale up to the fastest frame rate and the highest resolution the game supports and stays there.
In some games, such as Final Fantasy XV, you need to choose a mode with an unlocked frame rate in the game menus. So do check if there’s an in-game setting you need to tweak to let the PS5 stretch its legs a bit.
Game Boost Upgrades
The next type of free upgrade you can get for your PS4 games is PS5 Game Boost. This is a feature of the PS5 that only works with a limited number of approved PS4 games. PS4 games have to be validated for Game Boost. However, you don’t have to do anything other than keep your system software up to date since the Game Boost list and settings are built into the system software.
When a Game Boost compatible PS4 game is run on your PS5, it will benefit from additional performance from the console.
Games With Free PS5 Versions
Up to now, we’ve only covered passive PS4 upgrades that don’t actually require you to do anything special beyond keeping your system up to date and installing the PS4 game in question. However, certain PS4 games also have PS5 game versions.
These are two separate titles and, in-store, would come in different game boxes. However, some developers offer a free upgrade to anyone who owns the PS4 version. It’s entirely up to the developer whether they’ll offer the PS5 version of their game as a free upgrade or not. If you’re considering buying a PS4 game with the hope of getting the PS5 version, you’ll have to confirm eligibility for a free upgrade on a case-by-case basis.
At the time of writing, a handful of games are confirmed to have free PS5 upgrades. Some, such as Borderlands 3 and Maneater are ready to go. Others, such as The Witcher 3 and Cyberpunk 2077 have upgrades coming at a future date. So, in the case of a game like Cyberpunk 2077, you can buy the PS4 version now without any concern and get the PS5 version for free as soon as it becomes available. Here’s a list of notable titles with free upgrades, but this is not the full list:
- Assassin’s Creed Valhalla
- Borderlands 3
- Control Ultimate Edition (other versions don’t get a free upgrade)
- Cyberpunk 2077
- Destiny 2
- DIRT 5
- DOOM Eternal
- Far Cry 6
- Maneater
- Spider-Man: Miles Morales
- Nioh 2
- No Man’s Sky
- The Witcher 3
- Yakuza: Like a Dragon (digital version only)
You’ll note that some games, like Yakuza, only offer an upgrade for the digital version. So please check a given game for disc upgrade eligibility before you buy it.
Upgrading Disc-base Games
Before you ask, if you’ve bought the PS5 Digital Edition, which has no disc drive, there is simply no way to play or upgrade your PS4 disc games. If you’ve got a discless PS5, skip to the next section.
To upgrade eligible PS4 disc games to PS5, you’ll need to go through a few steps:
- First, make sure that you’re signed in with your account.
- Now, insert the PS4 game disc into your PS5’s drive.
- Now, go to the game’s Game Hub.
- There will be an upgrade offer, which will either be free or offered at a discount.
- Select Download or pay the discount fee and then download the game.
Once the upgrade is redeemed and you’ve downloaded the PS5 version of the game, the only catch is that the PS4 disc needs to be in the drive whenever you want to play the PS5 title.
Upgrading Digital Games
If you want to upgrade a digital game you own for the PS4, it’s even less complicated. You don’t have to worry about losing access to the PS4 version of the game. We were able to run both the PS4 and PS5 version of our games side by side on PS5. You also won’t lose access on your PS4, if you elected to keep yours. Here’s what to do:
- Sign into your account on your PS5.
- Open the PlayStation Store and go to the game hub page for the PS5 version of the game.
- You’ll see an upgrade offer or a discounted price for the PS5 version of the game.
- Select Download or pay the discounted price and then download the game.
After you’ve downloaded the game, you can simply launch it from your game library to play. That’s it! If you already had the PS4 version of the game installed on your system before downloading the PS5 version, you can delete it to save space.
The Pros and Cons of Upgrading To the PS5 Version of a Game
While it seems like a win-win to upgrade your PS4 game to the PS5 version, there are actually some downsides. To be clear, accepting the upgrade offer itself is perfectly fine. It’s just that PS5 games have certain restrictions that aren’t shared by PS4 games.
First of all, PS5 games can only be played from the internal SSD. With only around 667GB of available space and no way to back up games right now, that’s a very limited resource. PS4 games can run from any supported drive, including large external drives.
They don’t benefit from the incredibly fast internal SSD technology as much as native games. If you want the best loading performance for PS4 games without taking up internal SSD storage, we recommend using a USB SSD drive.
