reduce sound delay even more

disable extra sound updates
remove cheat flag on dsp_off, so users can set it for performance
disable async blocking spew
adjust networking defaults based on CSGO
66 packet rate, increased rate, adjusted SourceTV network defaults
remove paranoid OSX defaults
add con_filter_enable 3, which disables console logging
use host_timescale 0 as an optimized default
enable z buffer light cache, and fix crashes associated with maps with a lot of lights
increase hunk size from 48MB to 64MB
fully enable async mdl cache
unload textures on death rather than per frame
disable broken max packet drop implementation
enabled parallel snapshots
increased fps_max to 400, and minimum to 49 from 30
fixed allocation size bug in data cache
enabled filesystem buffering
exposed impact effect cvars to user
enabled water impact limits by default
enable raw input by default
increase max FOV to 120, default FOV to 90
skip particle function call
optimize cl_particle_retire_cost
disable match HUD for now
rendering optimizations
