Counter-Strike: Source Beta Reopened

Counter-Strike: Source Beta Reopened
Product Update - Valve 15:20
Starting today the Counter-Strike: Source Beta will be available to all PC Counter-Strike: Source players. As we continue to update CSS and address issues, we want to make sure to not destabilize the core game. By releasing updates to CSS Beta first, we will be able to solicit community feedback before those changes are applied to CSS.

If you would like to be part of the group that helps us test future updates of Counter-Strike Source, please join the Beta - simply install and launch "Counter-Strike: Source Beta" from your games list in Steam. To give feedback on the changes, report bugs, or offer suggestions, please use the CSS Beta forum. Don’t worry, you can join the Beta program and still play the standard Counter-Strike: Source at anytime. The Counter-Strike: Source Beta is currently not available on Mac.

Here are the change notes for today's CSS Beta release:

Fixed prediction errors that were causing greater weapon inaccuracy (bullet spread) on client than server.
Made the bomb the primary target of a USE command. This fixes a problem with objects placed around the bombsite interrupting defuse attempts.
Fixed the ‘skating’ behavior that could occur when a bomb planting attempt was aborted. Also fixes the resulting out of sync hit boxes.
Fixed bug in which a player who crouches rapidly and repeatedly was seen as stationery by other players.
Fixed problem in which the sound of a reload that was occurring when a player was killed persisted into spectator mode, making it sound like a reload was taking place near the spectated player.
Gave chat interface priority over scoreboard to reduce conflict between the two.
Increased size of HUD icons.
Fixed bug with env_hudhint that caused problems when its value was greater than 255 characters.
Added fcvar_archive flag to mat_hdr_level, r_rootlod, r_waterforceexpensive.
Made the message of the day screen dismissible by hitting ENTER.
Improved the look of the font on the achievement toast.
Fix servers not being to set sv_hudhint_sound
Added console variable cl_hudhint_sound
Added cvar sv_enablebunnyhopping, defaulted to 0. ( A value of 1 autotags the server with "bunnyhop" )

Additionally, we've made some Counter-Strike Beta only changes to simplify perf testing. These changes only exist in Counter-Strike Beta and will not affect Counter-Strike:

Disabled HDR
Disabled vsync
Disabled motion blur
Disabled stats
