Portal with RTX is a unofficial remastered version of Portal developed by Nvidia Lightspeed Studios, which takes advantage of newer hardware and adds ray tracing, DLSS, PBR textures, new high-poly models and much more, while also demonstrating RTX Remix technology on various game engines such as Source, allowing users to add ray-tracing, and other shaders, modern rendering features to any supported DX8-DX9 games.

It was released for free on December 8, 2022, for anyone who owns Portal on Steam. The game was developed using the RTX Remix tools, and runs on Direct3D 12^[1] after converting from Vulkan (using DXVK), which converts D3D9 calls and replaces several DirectX 7 level^[1][2] materials with PBR and ray-tracing capable textures.

It is only optimized for system with Nvidia GeForce RTX graphic cards. Users with AMD graphics card (including Steam Deck, which uses  AMD RDNA 2 like most 9th gen consoles) or Intel Arc graphics card may suffer from performance issues, when trying to run this game even with high-end card.

Portal RTX received mixed reviews at launch due to various reasons like the performance issues affecting some NVIDIA cards (and unplayable on systems with AMD Radeon), and the art-style & lighting seems out of place (which itself was based off Portal 2 instead of Portal 1 which looked more dirty).

Via Portal with RTX you can use RTX remix with Half-Life 2 and some other games by loading the map files, a tutorial can be found here. However, this method is highly buggy (as is running Half-Life 2 on Portal regularly), and lacks PBR textures.

Processor: Intel i7-6700, AMD Ryzen 5 3600 Graphics: NVIDIA GeForce RTX 3060 Memory: 16 GB RAM Storage: 25 GB or more, HDD OS: Windows 10/11 or later Other: Vulkan, DX12, ray-tracing capable GPU required DLSS highly recommended for weaker/lower-end GPUs, however, this will result in blurrier image.	Processor: Same as Minimum Graphics: NVIDIA GeForce RTX 3080 Memory: 16 GB RAM Storage: 25 GB or more, SSD	Processor: Intel Core i7-12700K, AMD Ryzen 9 5900 Graphics: NVIDIA GeForce RTX 4080 or higher Memory: 32 GB RAM Storage: 25 GB or more, SSD

Note:AMD or Intel graphics cards are not officially supported, which means that Portal with RTX will have worse performance when not using a Nvidia GPU.
System requirements may change over time depending how updates affect them.
