Portal 2 RTX Remix Compatibility Mod

This client modification is specifically made for nvidia's rtx-remix.
How does a shader based game work with remix? By manually reimplementing fixed function rendering :)

Description

WIP & Please Note:
RTX Remix was never intented to support Portal 2.
If you encounter crashes, broken things or similar, it's either due to incompatibility,
the limits of fixed function rendering or due to bugs in the compatibility mod itself.

This is not trying to be a remaster.

It simply makes the game compatible with RTX Remix.
Please keep that in mind.

Installation / Usage


✳️ Info:


⚠️ Troubleshooting (click to expand):

Do I need to start the game via the batch file every time? 
Yes. Asiloaders / dxwrapper will not load if the game is run from steam.


How do I disable remix? 
Run `p2-rtx-disable.bat` and follow the instructions to disable or the mod.  
The game will start afterwards to reset some required cvars.


Crashing, startup issues, not working ..

  • Make sure that you have no clipping software such as "medal" running in the background.

  • If your game is installed within Program Files:
    - right click portal2.exe and click settings - compatibility tab and enable run as admin
    - or install the game somewhere outside Program Files

  • Download and install DirectX End-User Runtimes (June 2010)


Portals not showing up - Game is too dark

Make sure that you installed the base-remix-mod via the installer or manually.
Some maps are not yet touched up, so if you are not rocking an additional community mod (for remix), some maps will be dark and water broken.


No sound
  • Either copy _master.cache from root/portal2/maps/soundcache to root/portal2_dlc3/maps/soundcache
    or paste this into the in-game console and execute: snd_rebuildaudiocache;snd_updateaudiocache;exit

P2-rtx
这是什么？这是一个 Portal 2 模组，通过手动重新实现游戏的固定功能渲染管线，让原版游戏兼容 Nvidia 的 RTX Remix 路径追踪框架。
这是完整重制版，还是只是一个兼容层？它是一个客户端兼容模组，不是重制版：它只是重新实现了 Portal 2 的固定功能渲染，让 RTX Remix 能对场景做正确的路径追踪。
怎么安装和运行它？下载最新发布版并按照安装程序的说明操作，之后始终通过随附的批处理文件启动游戏，不要直接从 Steam 启动。
除了模组本身我还需要什么？你需要一份 Portal 2、Nvidia 的 RTX Remix 运行时，以及 DirectX End-User Runtimes (June 2010)；发布版还附带一个专为 Portal 2 定制的 remix-dxvk 构建。
哪些地方可能出问题或变慢？有些地图尚未针对 Remix 光照做修整，可能显得昏暗或水面显示异常；某些地图因强制软件蒙皮而出现 CPU 瓶颈；声音还可能消失，直到你重建音频缓存为止。
它能在 Linux 上运行，还是只有 Windows？仅支持 Windows——安装涉及 Windows 批处理启动器、通过 dxwrapper 做的 DLL 挂钩，以及以管理员身份运行 portal2.exe 这类 Windows 特有的步骤。
必须要有 Nvidia RTX 显卡吗？是的——这个模组存在的意义就是把 Portal 2 接入 Nvidia 的 RTX Remix，它还添加了可选的 DLSS 4.5 Ray Reconstruction 和 DLSS 5.0 Neural Rendering 支持。
兼容层添加了哪些渲染特性？它添加了对 Remix 友好且支持手动覆盖的剔除机制、一个用于在事件发生时生成灯光并做动画的关键帧系统、按地图加载 Remix 配置、可动画化的 Remix 变量，以及唯一锚点网格的生成。
画面看起来不对劲时怎么关闭这个模组？运行随附的 p2-rtx-disable.bat，它会重置所需的 cvar，让 Portal 2 恢复正常启动。
它支持最新的 DLSS 特性吗？支持，当前发布版支持 DLSS 4.5 Ray Reconstruction 和 DLSS 5.0 Neural Rendering，其中 DLSS5 集成由社区成员 Sparkles 贡献。
这是 Nvidia 的官方发布吗？不是，这是一个社区模组；Nvidia 和 RTX Remix 工程师因提供支持而获得致谢，但项目由模组作者和贡献者们制作并维护。
