游戏内画面设置在bilibili中有十分具体的保姆式教学
若嫌麻烦或效果不佳可参照本文针对性更强的方法

登录-扫描游戏-优化
可根据性能要求自定义画面


选择程序-“Hogwarts Legacy”
电源管理模式设置为“最高性能优先”
其他设置若不懂如何操作则无需更改，默认选项即可，并无显著性能差异。

在进行如上画面设置后，基本只能流畅序章，分院结束后将开始掉帧地狱。
无论是打群架、骑扫帚、切换场景、快速转镜头，都会出现让人无法接受的掉帧场景。

此MOD可以改善游戏当前版本的卡顿和掉帧问题。它实现了一些引擎调整，例如强制 CPU 到 GPU 的通信和同步、启用纹理流并调整它以尽可能优化工作等等。

安装注意事项
确保您至少启动过游戏一次，以便生成文件。
下载并运行安装程序并单击"INSTALL"。
（若想卸载则再次打开文件选择"UNINSTALL"即可）


"Ascendio" is a series of Unreal Engine 4.27.2 custom engine parameters which aim to improve the current stuttering and fps drops the game suffers from. It implements some engine tweaks like force CPU to GPU communication and sync, force frame finalization on stuck, enables texture streaming and tweaks it to work as optimal as possible, and a few more.
Some performance issues are actual backend bugs on the implementation of some core functions of the game. I've tracked an issue with the NPC generation. That bug needs more work to get properly addressed and chances are Avalanche will actually fix it way faster than I'd be.
This mod "helps" with stuttering, specially with RT turned off, but it doesn't fix it completely. Hopefully it will make the experience smoother for you though until the dev team launches a proper patch.
The mod has been distributed with a fancy installer application for user convenience. Make sure you have .NET 6 (or greater) installed on your computer if you can't run the application. Chances are you already have this software in your PC if you use it to run games, so no worries.
Make sure you have launched the game at least once so the files can get generated.
Download Ascendio Installer from the files tab.
Run the installer and click "install".
Hit next and close the application.
Of course, if you need to uninstall the mod, just run the application again, but click "uninstall". A pop-up window will let you know the uninstallation process finished successfully, and the installer will close after pressing "ok".

诸如笔者的16G RAM只达到了运行该游戏的最低需求，在运行时RAM占比常在95%以上。
此方法百度即可，以下文字说明从百度复制而来。
1.用右键点击桌面上的我的电脑图标，在出现的右键菜单中选属性选项打开系统属性窗口。在窗口中点击高级选项卡，出现高级设置的对话框。
2.点击性能区域的设置按钮，在出现的性能选项窗口中选择高级选项卡，打开其对话框。
3.在该对话框中可看到关于虚拟内存的区域，点击更改按钮进入虚拟内存的设置窗口。选择一个有较大空闲容量的分区，勾选自定义大小前的复选框，将具体数值填入初始大小、最大值栏中，而后依次点击设置确定按钮即可，最后重新启动计算机使虚拟内存设置生效。



下载程序Reduce Memory
1.打开程序ReduceMemory_x64.exe

2.选择“选项”，如下图进行设置
运行游戏前打开该应用，或者开机自动启动此应用。
进游戏基本RAM在60%以下。


以上。
