Following some teething problems with the most recent update to CS:S there has been another update from Hidden Path. It is hoped that the update will resolve most of the issues around firing guns now, not least of which was the phantom extra bullet that would arrive with single taps.
Many in the competitive community felt that the last update had rendered the game unplayable with the firing bug but Hidden Path have moved quickly to fix it. Clearly though the CS:S overhaul still has a long road ahead of it.
The changelog read as follows:
Counter-Strike: Source
- Fixed new weapon firing integration causing some guns to over-fire on single taps
- Fixed a couple of cases where machine guns could skip slightly with enough lag
- Fixed c4 explosion pre-caching
- Added precise audio timing fixes for client-side prediction
- Increased the tolerance for skip detection in client side audio to prevent sound dropping out due to client clock drift
- Completed work on clan tag strings validation
