Essential improvements[edit]

Skip intro videos[edit]

Use the -novid command line argument[2]
-no-browser disables server video ads.

Increase performance[edit]


The game has some compatibility issues with older operating systems such as Windows 7 due to the outdated graphics stack (WDDM).[3]
You can disable fullscreen optimizations to reduce FPS drops and improve response time through the properties of the launch file in the compatibility section (in Windows 10 in some cases it may cause performance drop)[3]
Enable DirectX 9Ex mode
  1. Open Steam.
  2. Go to launch options CSGO.
  3. Enter -d3d9ex and save.
  4. You can also uncap your FPS +fps_max 0.
Since March 2019, the DirectX 9Ex functionality has been returned to the version of this CSGO engine.[4]
Support for this renderer is available starting only from Windows Vista and newer for Windows 7/8/8.1/10.
Perhaps a negative effect for users of video adapters from AMD (but not in all cases)[5]
You can also disable the function of HPET which is a technology of high-precision timer in the motherboard.
This can sometimes cause performance problems.
You can keep timer resolution manually.
Disable HPET[6]

Method 1:

  1. Tap on the Windows-key, enter cmd, right-click cmd.exe in the results listing and select to run the command prompt with administrative privileges.
  2. To enable HPET as the only timer run the command bcdedit /set useplatformclock true
  3. To disable HPET in Windows run the command bcdedit /deletevalue useplatformclock
  4. Restart your computer.

Method 2:

  1. Search "Device Manager" on your PC.
  2. Scroll down to "System Devices" and open the sub-menu.
  3. Scroll to "High Precision Event Timer" and click it.
  4. Click "Actions" at the top of the window, and from that pop-up menu, click "Disable".
  5. Restart your computer.
For further solutions check out also this section below.

Increased Stability (32-bit version of Windows)[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 <Steam-folder>\userdata\<user-id>\730\local\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.


Enable OpenGL Multithreading

In Steam's Launch Options... add the following environment variable depending on the GPU you are using:

  • mesa_glthread=true if using AMD/Intel GPU with Mesa driver library (Not needed if on Mesa 20.2 or higher)
Enable Vulkan

Use -vulkan launch option

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[7]

Host 128 tickrate servers[edit]

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

Use the -tickrate 128 command line argument[2]

Config Generator[edit]

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

Reportedly other issues with surround sound with the Logitech G35.[16]

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

FPS drops and/or stuttering[edit]

Exclude CS:GO folder from your anti-virus[citation needed]
Update Realtek audio drivers[17]
Disable Advanced 3D audio processing in the audio menu[18]
Install the game on SSD[19]
(AMD) Turn on Radeon Anti-Lag in Radeon Settings (generally not recommended on 97% of GPU usage and lower).[20]
(AMD) Turn on Enhanced Sync in Radeon Overlay (Alt+R) or Radeon Settings (especially if you suffer FPS drops below 60, but technically it prevents tearing).[21]
Disable Profanity filter in Settings>Social[22]
Disable Boost Player Contrast in Settings>Video
Use launch parameters:

-d3d9ex -novid -no-browser -nojoy -high +r_dynamic 0 +cl_freezecameffects_showholiday 0 +r_drawtracers_firstperson 0 +fps_max 0[23]

You can also use +cl_draw_only_deathnotices 1 to disable HUD which slightly increases FPS[24]
Popular net_graph 1 / net_graph_text 1 causes slight FPS drop[25]
+r_drawtracers_firstperson 0 disables visibility of fired bullets. Enabling it may be useful with e.g. M249 to correct recoil while shooting full auto. You need to enter it manually in console.
Bear in mind, that some commands increasing FPS in e.g. Dust 2, can decrease FPS in newer maps like Lunacy. These presented on the top were tested thoroughly on both.
Alternatively you can test +mat_queue_mode 2 for 4+ core CPUs and -noubershader for at least old Intel iGPUs[26]
Disabling default FPS limit is beneficial mainly in scenarios of fluctuating FPS between 60-120.
+cl_forcepreload has been removed with the patch on 24.09.21.

Game crashes with window "Wait for the program to respond"[edit]

Need use 4GB patch[27]
  1. Go to NTCore site [4].
  2. Download the 4GB Patch.
  3. Open archive and run 4g_patch.exe.
  4. Select executable file of game csgo.exe for patch.
Despite the actions for patching the launch file of the game, this does not lead to a VAC ban account.[citation needed]
It is also possible to increase the performance of the game due to the increase in the address space after the patch.
If you encounter error that executable cannot be patched, make sure that it's possible to delete it before, and restart computer to fix it if necessary.
If patcher didn't change binary checksums, it is already patched.
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[28]
  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 -1.


Removing the line does not work.
Disable exclusive control of microphone (Windows)[29]
  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[30]
  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[31]
  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[32]
  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 of sound / var value jumps[edit]

Add launch parameter in Steam +cl_disablehtmlmotd 1 and/or alternatively -no-browser[33]

Game crashes on start[edit]

Delete <path-to-game>\csgo.exe and "verify integrity of game files" in properties of the game on Steam
Make sure <path-to-game>\csgo.exe has no compatibility modes applied

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
  2. Select the "Gaming" section
  3. Set "Record game clips, screenshots, and broadcast using Game Bar" to off

Microphone not working[edit]

Visit the archlinux Wiki[citation needed]

Black screen on launch, but audio can still be heard[edit]

Launch the game with the -disable_d3d9ex parameter[34]
Launch the game with the -fullscreen parameter[35]

Rendering issues on AMD/Intel under Linux[edit]

Will be fixed in the upcoming Mesa 21.1
Warning! Currently it causes a breakage in a trust factor when using it, you may be thrown into a match with cheaters![36]
Run the game with radeonsi_clamp_div_by_zero=true environment variable

"No user logon"[edit]

When playing in offline mode, make sure you don't have internet access in background, otherwise the game will kick you from the game after some period of time.

"Your graphics hardware does not support all features (CSM) needed"[edit]

The game will fail without Cascaded Shadow Mapping support.[37] Unfortunately the feature is hardcoded to be available only on the three common GPU vendors.[38]
Launch the game with the -force_device_id 0xffff -force_vendor_id 0x8086 command line arguments[39]
Try the other fixes in "High" shadow detail option is missing

"Failed to verify signed files" error when trying the old demo viewer[edit]

This happens since Valve added game executable signature validation into the Steam client itself[40]
Disable Steam signature verification
  1. Open the Steam console (steam://open/console).
  2. Run the command verifySignaturesBeforeLaunch 0.
Run <path-to-game>\csgo.exe directly
If the game just closes after launch try to still actually validate the game files once.

Steam constantly asks for admin permissions on start[edit]

Execute the reg add HKLM\SOFTWARE\Valve\Steam\Apps\730 /v directx /t REG_DWORD /d 1 /f /reg:32 command

Screen not stretching on AMD graphics card[edit]

  • Turn on GPU Scaling, change Scaling Mode to Full Panel and most importantly, turn off Integer Scaling.
  • These settings can be found in Settings -> Display of Radeon Software.
  • If you don't want to change the global settings, it can also be changed just for CS:GO in the Gaming tab
