Essential improvements

Skip intro videos

Use the -novid command line argument[4]
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]
  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 crashes.

Config Generator

Issues fixed

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

See the official Steam support page here

FPS drops and/or stuttering

Update Realtek audio drivers[15]
Disable Advanced 3D audio processing in the audio menu[16]
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).[17]
(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).[18]
Disable Profanity filter in Settings>Social[19]
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:

  • 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[20]

Method 1:

  1. Open the Windows Command Prompt or PowerShell as administrator.
  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 the computer.

Method 2:

  1. Open the Windows Device Manager.
  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 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[21]

You can also use +cl_draw_only_deathnotices 1 to disable HUD which slightly increases FPS[22]
Popular net_graph 1 / net_graph_text 1 causes slight FPS drop[23]
+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[24]
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[25]
  1. Download the NTCore 4GB Patch.
  2. Apply the patch to csgo.exe

Game changes microphone gain at launch

Modify configuration file[31]
  1. Go to the configuration file(s) location.
  2. Open config.cfg.

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

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.[34] Unfortunately the feature is hardcoded to be available only on the three common GPU vendors.[35]
Launch the game with the -force_device_id 0xffff -force_vendor_id 0x8086 command line arguments[36]
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.[37]
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[38]
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 validate the game files at least once.
