de_dust2 in Counter-Strike 2. It is also the most recent and latest Source 2 game to be released.
Source 2 is a 3D video game engine developed by Valve as a successor to 
Source.
Introduced in 2015, it is used in Dota 2, SteamVR Home, Half-Life: Alyx, S&box, Counter-Strike 2, and much more.
Development of Source 2 was planned after the release of Half-Life 2: Episode Two and other The Orange Box games. In 2010, Left 4 Dead 2 was privately ported to the Source 2 engine as a tech demo, with one of the maps recreated in the Source 2 engine. The engine was later made public with the Dota 2 Workshop Tools Alpha in August 6th 2014 and formally announced by Valve in March of 2015 at the Game Developers Conference. It was then implemented into Dota 2 on June 17th 2015. Valve has announced that Source 2 will be released to the public for free, and it will only take money should it be used for commercial products.
The engine is capable of rendering highly complex and well detailed scenes with minimal framerate drops, thanks to its new 64-bit support alongside Vulkan, Direct3D 11, allowing for better multi-core rendering, better graphics and more efficient 3D rendering.
Features

New Source 2 features introduced in 
Counter-Strike 2
- Volumetric smokes
- Smokes are now volumetric objects, that can be pushed by grenades, bullets, and more. It also react to lighting and the smokes fill the spaces naturally.
- Sub-tick system
- Tick rate no longer matters for moving, shooting, or throwing.
- Improved Steam Audio
- Sounds have been reworked to better reflect the physical environment, be more distinct, and express more game state. They have also been rebalanced for a more comfortable listening experience.
- Hardware accelerated ray-tracing for VRAD
- VRAD3 now requires graphics card with ray-tracing support to preview & bake lighting. This will allow VRAD to quickly calculates lighting data.
Limitations
Upozorenje:Support for 32-bit, OpenGL, DirectX 9 (includes Direct3D 9), XAudio, and macOS versions below 10.14 were removed in 2021 with the Dota 2 update. SteamVR Home is not affected. Newer games such as Half-Life: Alyx and Counter-Strike 2 don't support them.Newer games like Counter-Strike 2 will also require a CPU with SSE 4.2 support.
Upozorenje:Some games like Counter-Strike 2 no longer support Squirrel, making things non-trivial to port and with no chance of a proper transition period when both implementations are functional.Products using Source 2
