Essential improvements

Skip intro videos

Use the -novid command line argument

The console command cl_disablehtmlmotd 1 disables servers' Message Of The Day (MOTD) advertisements.

Configure memory usage on 32-bit versions of Windows

The game can crash when loading the next map if on a 32-bit operating system.

This is caused by going over 4 GB of total memory usage, which is impossible for a 32-bit OS.

setting.mem_level[citation needed]
Go to <Steam-folder>\userdata\<user-id>\730\local\cfg Open video.txt. Find setting.mem_level and replace "1" with "0" Launch the game, and load several maps in a row to make sure it worked. Notes Turning down settings such as shadow or model resolution can also help to prevent crashes.

Config Generator

Special singleplayer map that allows players to configure settings that are not normally accessible via in-game UI.

See the official Steam support page here

FPS drops and/or stuttering

Update Realtek audio drivers

Disable Advanced 3D audio processing in the audio menu

Disable fullscreen optimizations in the executable's compatibility settings

(AMD) Turn on Radeon Anti-Lag in Radeon Settings (generally not recommended on 97% of GPU usage and lower).

(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).

Disable Profanity filter in Settings>Social

Disable Boost Player Contrast in Settings>Video

Enable OpenGL Multithreading (Linux)
In Steam's Launch Options... add the following environment variable depending on the GPU you are using: __GL_THREADED_OPTIMIZATIONS=1 if using NVIDIA mesa_glthread=true if using AMD/Intel GPU with Mesa driver library (Not needed if on Mesa 20.2 or higher)

Enable Vulkan (Linux)
Use -vulkan launch option

Disable HPET

Method 1: Open the Windows Command Prompt or PowerShell as administrator. To enable HPET as the only timer, run the command bcdedit /set useplatformclock true To disable HPET in Windows, run the command bcdedit /deletevalue useplatformclock Restart the computer. Method 2: Open the Windows Device Manager. Scroll down to "System Devices" and open the sub-menu. Scroll to "High Precision Event Timer" and click it. Click "Actions" at the top of the window, and from that pop-up menu, click "Disable". Restart the computer. May cause performance issues on some systems. The timer resolution can be changed manually.

Use launch parameters: -d3d9ex -novid -no-browser -nojoy -high +r_dynamic 0 +cl_freezecameffects_showholiday 0 +r_drawtracers_firstperson 0 +fps_max 0 You can also use +cl_draw_only_deathnotices 1 to disable HUD which slightly increases FPS Popular net_graph 1 / net_graph_text 1 causes slight FPS drop +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. It needs to be entered manually in the console. Some commands which increase 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, test +mat_queue_mode 2 for 4+ core CPUs and -noubershader, at least for old Intel integrated GPUs Disabling the default FPS limit is beneficial mainly in scenarios of fluctuating FPS between 60 and 120. +cl_forcepreload has been removed with the patch on 24.09.21.

Game crashes with window "Wait for the program to respond"

Need use 4GB patch
Download the NTCore 4GB Patch. Apply the patch to csgo.exe This does not lead to a VAC ban account.[citation needed]

Game crashes without an error message when loading into a server

Reduce in-game resolution[citation needed]
Before joining a server, set the resolution in-game down to the first lower setting. Once connected, set the game resolution back to the previous one. This does not need to be redone until the game is closed.

Add the Counter-Strike: Global Offensive and Steam executables to firewall exception lists[citation needed]

Adjust your maximum acceptable ping to official servers[citation needed]
Type mm_dedicated_search_maxping "150" in your game console. Notes You might want to add the above command to your autoexec.

Game crashes on start

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

Steam constantly asks for admin permissions on start

Using the Command Prompt or PowerShell, execute the reg add HKLM\SOFTWARE\Valve\Steam\Apps\730 /v directx /t REG_DWORD /d 1 /f /reg:32 command

"No user logon"

When playing in offline mode, make sure Internet access is disabled in the operating systems.

Black screen on launch, but audio can still be heard

Launch the game with the -disable_d3d9ex parameter

Launch the game with the -fullscreen parameter

30 FPS cap after Windows 10 Anniversary Update

Some people report that games run worse (not only CS:GO). It is also known that the AU update broke graphics card drivers.

An update for the game was released which added a warning for users who have XboxDVR enabled.

Disable Game Bar[citation needed]
Open the Settings App Select the "Gaming" section Set "Record game clips, screenshots, and broadcast using Game Bar" to off

Purple and black broken textures

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

Some maps are way too dark on Intel HD GPUs

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.

Game changes microphone gain at launch

Modify configuration file
Go to the configuration file(s) location. Open config.cfg. 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. Set the value to -1. Notes Removing the line does not work.

Disable exclusive control of microphone (Windows)
Right click on the speaker icon located at the tray bar. Select Recording devices. Double click on your microphone in the newly opened window. Go to Advanced and untick Allow applications to take exclusive control of this device. Notes Most applications ignore this, and many users are reporting that it does not work.

FPS drops and/or stuttering of sound / var value jumps

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

Screen not stretching on AMD graphics card

Disable Integer Scaling in the AMD control panel

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

The game will fail without Cascaded Shadow Mapping support. Unfortunately the feature is hardcoded to be available only on the three common GPU vendors.

Launch the game with the -force_device_id 0xffff -force_vendor_id 0x8086 command line arguments

Try the other fixes in "High" shadow detail option is missing

Microphone not working on Arch Linux

Visit the archlinux Wiki[citation needed]

Rendering issues on AMD/Intel under Linux

Will be fixed in the upcoming Mesa 21.1

Currently it causes a breakage in a trust factor when using it, and players may be thrown into a match with cheaters.

Run the game with radeonsi_clamp_div_by_zero=true environment variable

Crashing on launch on Linux

Run sudo dmesg | grep malloc in the terminal. If you see any issues with CSGO and malloc, apply the following fix:

libtcmalloc Segmentation Fault Fix Delete the contents of this directory: <path-to-game>\csgo/panorama/videos/ Add -novid to the end of your launch options.

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

This happens since Valve added game executable signature validation into the Steam client itself

Disable Steam signature verification
Open the Steam console (steam://open/console). Run the command verifySignaturesBeforeLaunch 0.

Run <path-to-game>\csgo.exe directly
If the game just closes after launch, try to validate the game files at least once.
