A reference to CS:GO with Source 2 engine found in Nvidia driver
For some time now, rumours have been circulating online that Valve is going to update Counter Strike: Global Offensive to its latest game engine, and these rumours have clearly been reinforced after the Aquarius dataminer found a configuration profile called "Counter Strike 2" in the latest Nvidia drivers. It refers to "csgos2.exe", which can only mean "Counter Strike Global Offensive Source 2". The author of PC Gamer looked at the driver with Nvidia Profile Inspector and indeed found this profile there.
All of this can mean only one thing - a Source 2 version of Counter Strike is inevitable, although it is not very surprising, since, for example, DOTA 2 switched to a new engine back in 2015. But the question is, how important is this for the game? When DOTA 2 switched to Source 2, it added the Custom Games feature, which was a significant innovation, and ultimately created the battle royale genre. But it's not that custom maps are not created for CS:GO - there are thousands of them!
Perhaps Valve will add something more interesting with the move to the new engine, but if it's really just a de_dust update, the average player may not notice much when the switch happens.
