Here you will find config files that pros use for playing on the hardest difficulties. Using these configs it will be easier to master the skill of using grenade launcher, chainsaw and overall the game will feel more responsive. autoexec.cfg All the files below can be downloaded here[www.dropbox.com]. Firstly create autoexec.cfg, example: C: Program Files (x86) Steam steamapps common Alien Swarm Reactive Drop reactivedrop cfg autoexec.cfgIf your Steam is installed in different location, use your own path. Put this into your autoexec.cfg: // network client settings cl_interp_ratio 0// lower interpolation to see the actual drone position, default 2 cl_interp 0// disables interpolation, other marines may, default 0.1 rate 120000// network bandwidth ~120 KBps, default 30000 cl_cmdrate 100// how many times per second your client sends data to server, default 30 cl_updaterate 59.94 // how many times per second your client recieves data from server, default 20 r_maxdlights 4// limit dynamic lights to 4, default 32. This makes framerate more stable. Dynamic lights are muzzle flashes from rifles, and fire on map. // visual settings asw_camera_shake 0// disables camera shake when explosions are close mat_grain_enable 0// disables film grain effect mat_motion_blur_enabled 0// disables motion blur effect(when camera moves too fast) mat_bloom_scalefactor_scalar 0 // disables bloom effect mat_depth_blur_strength_override 0 // disables depth blur effect mat_vignette_enable 0// disables "darkening" on the sides of the screen rd_health_effect 0// disables red screen blinking when low on health rd_hearbeat 0 // disables heart beating sound when low on health asw_marine_death_cam_slowdown 0 // disables game slowdown when marine dies // network server settings(if you host server from your game) net_splitpacket_maxrate 120000// if you host, other players will have smoother game sv_maxrate 120000// if you host, other players will have smoother game newmapsettings.cfg Open file C: Program Files (x86) Steam steamapps common Alien Swarm Reactive Drop reactivedrop cfg newmapsettings.cfgRemove what's in it and put this: // all settings here are default, except fps_max and several cvars moved to autoexec.cfg mat_grain_scale_override 1.5 mat_local_contrast_enable 1 ai_no_steer 1 crosshair 1 r_flashlight_topdown 1 r_flashlightscissor 0 fx_glass_velocity_cap 600 cam_idealyaw 0 cam_idealpitch 90 cam_idealdist 412 fov_desired 75 c_maxpitch 360 c_maxdistance 1000 cl_retire_low_priority_lights 1 mat_grain_enable 0 // disables grain effect mat_vignette_enable 0 // disables darkening of the screen corners effect // recommended to put this double the refresh rate of your monitor, 60 Hz = fps_max 120 fps_max 120 loadouts.cfg Create file C: Program Files (x86) Steam steamapps common Alien Swarm Reactive Drop reactivedrop cfg loadouts.cfgPut this inside it: //-------Default Loadouts------- //-----Sarge----- asw_default_primary_0 3 // Vindicator asw_default_secondary_0 20 // Grenade Launcher asw_default_extra_0 10 // ECA //-----Jaeger----- asw_default_primary_4 3 // Vindicator asw_default_secondary_4 20 // Grenade Launcher asw_default_extra_4 11 // Fire Mines //-----Vegas----- asw_default_primary_7 18 // Chainsaw asw_default_secondary_7 20 // Grenade Launcher asw_default_extra_7 10 // ECA //-----Faith----- asw_default_primary_2 9 // Tesla Cannon asw_default_secondary_2 11 // Medical Gun asw_default_extra_2 7 // Freeze Grenades //-----Bastille----- asw_default_primary_6 9 // Tesla Cannon asw_default_secondary_6 11 // Medical Gun asw_default_extra_6 7 // Freeze Grenades //-----Wolfe----- asw_default_primary_5 15 // Minigun asw_default_secondary_5 7 // Ammo asw_default_extra_5 10 // ECA //-----Wildcat----- asw_default_primary_1 15 // Minigun asw_default_secondary_1 7 // Ammo asw_default_extra_1 10 // ECA //-----Crash----- asw_default_primary_3 20 // Grenade Launcher asw_default_secondary_3 7 // Ammo asw_default_extra_3 10 // ECA Conclusion For better mouse responce it is recommended to play in full screen, go to game's Main Menu: Options - Video - Display Mode - FullscreenOptions - Video - Advanced Settings - Wait for Vertical Sync - Disabled As the result of these settings it is easier to play. More accurate alien positions help to not self nade, also it's easier to work with chainsaw, because you see alien positions more accurately. As a negative part some players may move jittery on your screen, also it puts more stress on your internet bandwidth. Thanks to Bounty for the configs provided.
