con_restricted [0,1] - If set to 0 this will unlock the console to be able to write all cvars directly in the console. It is by default set to 1, allowing only a limited of cvars to be written.
s_maxchannels = 128 - Defines the maximum allowed channels to be used.
hud_showAllObjectives [0,1] - Show all on screen objectives, not only the active one.
gpu_particle_physics [0,1] - If set to 1, appears to enable the processing of particle physics on the GPU (graphics card). Since the particle system is already threaded (see e_particles_thread), this setting will likely only improve performance on systems with single-core CPUs and fast graphics cards (system).
e_particles_thread [0,1] - Determines whether the particle system - if enabled - is threaded or not. This should always be set to 1 on a system with a multi-core CPU to provide optimal performance, as it prevents additional slowdowns during explosions and combat. In fact this is one of the reasons why Crysis doesn't suffer from major slowdowns during the highly detailed explosions on multi-core systems (system).
sys_physics_cpu [0,1] - The default setting will unsyncs physics from the GPU framerate.If set to 0 this will syncs physics with the gpu.
log_FileVerbosity 0,1] - Defines the verbosity level for file log messages (if log_Verbosity defines higher value this one is used).
0 = suppress all logs(except eAlways) 1=additional errors 2=additional warnings 3=additional messages 4=additional comments.
log_Verbosity [0,1] - Defines the verbosity level for console log messages (use log_FileVerbosity for file logging)
0=suppress all logs(except eAlways) 1=additional errors 2=additional warnings 3=additional messages 4=additional comments
r_MotionBlur [0,1,2,3,4,5,101,102,103,104] - This setting controls the use of Motion Blur, which is most visible when turning around in the game. Setting it to 0 disables this form of blurring and can noticeably improve FPS; 1 enables it; 3 enables it and also allows it to blur not just your view, but also blur fast moving objects in DX10; 4 enables it and allows object motion blur in DX9 mode. Each level progressively lowers FPS. Again, it should be kept in mind that to get full object motion blurring in DX9 (e.g. the blurring on the movement of your own arms), you need to set this command to 5 (which is above the Very High level), whereas it occurs at 3 in DX10 Very High mode, and you also need to also make sure q_Renderer=3 for it to work.
