Essential improvements[edit]

Skip intro videos[edit]

-no-browser disables server video ads.

Increased Stability (32-bit Operating Systems)[edit]

CS:GO can crash when loading the next map if you're on a 32-bit operating system. To address this, you'll need to edit a txt file.
The crash is caused by going over 4 GB total memory usage, which isn't possible for a 32-bit OS.
setting.mem_level[citation needed]
  1. Go to <path-to-game>\csgo\cfg\
  2. Open video.txt.
  3. Find setting.mem_level and replace "1" with "0"
  4. Launch the game, and load several maps in a row to make sure it worked.


Turning down settings such as shadow or model resolution can also help to prevent CTD's.

Make current custom community server joinable[edit]

CS:GO won't broadcast the server you're connected to if you're playing on a community server.

Use the cl_join_advertise 2 command[2]

Host 128 tickrate servers[edit]

By default self-hosting a server will always launch in 64 tickrate.

Use the -tickrate 128 command line argument[1]

Config Generator[edit]

Special singleplayer map that allows you to configure settings that aren't normally accessible via in-game UI.

Issues unresolved[edit]

Surround sound[edit]

Reportedly other issues with surround sound with the Logitech G35.[10]

Issues fixed[edit]

"An issue with your computer is blocking the VAC system. You cannot play on secure servers."[edit]

See the official Steam support page here

Delete appcache

If you get this error message without have used any 3rd party applications, this quick fix should solve your issue.

  1. Shut down Steam.
  2. Go to <Steam-folder>.
  3. Delete the folder appcache.

Game changes microphone gain at launch[edit]

Modify configuration file[11]
  1. Go to the configuration file(s) location.
  2. Open config.cfg.
  3. Find the line voice_mixer_volume, it should be near the bottom of the file. If the line doesn't exist you may create it.
  4. Set the value to whatever you prefer your mic volume to be, I set mine to .5 which translates to 50% gain.


Removing the line does not work.
This will set a fixed value, and might not be a solution for people who are using dynamic gain which Windows (or other applications) automatically adjusts.
Disable exclusive control of microphone (Windows)[12]
  1. Right click on the speaker icon located at the tray bar.
  2. Select Recording devices.
  3. Double click on your microphone in the newly opened window.
  4. Go to Advanced and untick Allow applications to take exclusive control of this device.


Most applications ignores this, and many users are reporting that it isn't working.

Game crashes without error message when loading into a server[edit]

Reduce in-game resolution[citation needed]
  1. Before joining a server, set your resolution in-game down to the next lowest setting (e.g, if you're running 1920x1080, go down to 1776x768).
  2. Once you get in, set your game resolution back to whatever you normally use. You don't need to use this workaround again until you restart the game.

Failed to find and connect to an acceptable dedicated server[edit]

Windows Firewall[citation needed]
  1. Open the firewall and enable the following:
  • steaminstall
  • steam
  • hl
  • hl2
  • steamTmp
  • csgo
Adjust your maximum acceptable ping to official servers[citation needed]
  1. Type mm_dedicated_search_maxping "150" in your game console.


You might want to add the above command to your autoexec.

Error 55[edit]

Opt out of the Steam beta client[13]
  1. Open the Steam menu at the top left in the Steam Client and click on Settings.
  2. Click Account at the left hand of the window.
  3. Go to the 'Beta participation' (It will say 'Steam Beta Update' if you are opted in) and click Change....
  4. Open the drop-down menu and change it to None - Opt out of all beta programs.
  5. Click OK.
Re-enable the Steam service[14]
  1. Exit Steam.
  2. Type C:\Program Files (x86)\Steam\bin\Steamservice.exe /Install at the Run prompt.
  3. Restart Steam.
Delete ClientRegistry.blob and AppUpdateStats.blob[15]
  1. Go to <Steam-folder>.
  2. Delete ClientRegistry.blob and AppUpdateStats.blob.

Purple and black broken textures[edit]

A generic fix for this issue can be found on our Source engine page.

Some maps are way too dark on Intel HD GPUs[edit]

Maps using ambient occlusion (e.g. de_lake, de_canals, ar_baggage) can be very dark on Intel HD Graphics.

A generic fix for this issue can be found on our Source engine page.

FPS drops and/or stuttering[edit]

Exclude CS:GO folder from your anti-virus[citation needed]
Update Realtek audio drivers[16]
Disable HRTF in the audio menu[citation needed]

Crashes of the game / FPS drops and/or stuttering of sound / var value jumps[edit]

[17] [18] Problem visualized here

Add launch parameter in Steam cl_disablehtmlmotd 1
Delete csgo.exe from Steam\Steamapps\common and "verify integrity of game files" in properties of the game on Steam
Check whether all options in properties>comaptibility of csgo.exe are unchecked

30 FPS cap after Win10 Anniversary Update[edit]

Some people report that games run worse (not only CS:GO). It is also known that the AU update broke graphics card drivers. Should be noted that an update for the game was released which added a warning for users who have XboxDVR enabled.

Disable Game Bar
  1. Open the Settings App
