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 on the 
Source engine, 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 Vulkan hooked on top of DirectX 7 feature level[1].
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 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.

Note:This game is not optimized for systems with 
AMD or Intel graphics cards, which means that Portal with RTX will usually perform worse when not using a 
Nvidia GPU.System requirements may change over time depending how updates affect them.

According to Video - Advanced window shown on that video, the game appears to run on DX7 feature level, despite it was deprecated since
Source 2009 or 
Source 2013 (which would have force it to DX8 mode).
