The four rows found are responsible for the new effects in CS:GO. Gabe Follower noticed the presence of a direct reference to a smoke grenade, which may mean a fix with the transition to Source 2 of a long time bug, when sometimes player model silhouette could be visible in a cloud smoke.
Previously, enthusiasts found evidence of Valve's shooter on a new engine in the extended toolset for developers of modifications in Half-Life: Alyx.
Source 2 is used in Dota 2, Half-Life: Alyx and other Valve games. Experts believe that CS:GO transition to a new engine may improve performance, but will not have a significant impact on the graphics and physics of the game.
