This repairs your broken game files, if you have had any issues with the game, you should always try this first and see if the problem still exists. Let it complete and then start CS:GO. It will reinstall DirectX, which could take a few minutes.
This will not delete any of your settings in-game.

Steam > Library > (Right-click) Counter-Strike: Global Offensive > Properties > LOCAL FILES > VERIFY INTEGRITY OF GAME FILES...

You should also do this after you follow the tips in the guide.
If you made a change in your settings, you should restart CS:GO and then use the map again.

Download the benchmark map from the Workshop.
When start the map, go into Counter-Terrorist team and shoot in the middle of the big board and let the map do its thing. You should run this test at least 3 times and write down your results each time.

This step is to backup your current CS:GO configs if anything goes wrong, e.g. if you lose your keybinds or settings.

You can find your config in C:\Program Files (x86)\Steam\userdata\(custom ID)\730\local\cfg

For NVIDIA users: you should also make a screenshot of your NVIDIA 3D Program Settings.

Before updating your drivers, always make a System Restore Point, so you can revert your computer to the drivers which were working.

How to Create a System Restore Point in Windows 10

This will be a short go through about my testing and which caused me more FPS LOSS.

Turning OFF hyper-threading: This actually made me lose almost 50 FPS on average (a lot of people recommend to turn this OFF if you got an Intel i7 processor. I remember this actually worked when I first got this computer, same as selecting cores in msconfig, but it doesn't work anymore).

Locked CPU cores in msconfig and BIOS.

mat_queue_mode 0 / 1 / 3
(Now using 2, but -1 seems to work the same for me)

Adding and removing -high from launch options. It made no difference for me, but Valve recommended against it, because they don't test it.

Adding -threads to launch options (tried 1 - 12), all gave me a huge FPS loss.

Unchecking Fullscreen Optimizations for csgo.exe It gave me a huge FPS loss, but krafko/smaug1 says it really helped him and a lot of his friends.

How to add Launch Options:
Steam > Library > Games > (Right-click) Counter-Strike: Global Offensive > Properties > SET LAUNCH OPTIONS...

Most optimal Launch Options:

There are some other Launch Options you could use:

• -console (opens console on start)
  
• -language (title) (changes your CS:GO to a custom language pack you have)

Do not use these commands. They were either unapproved by Valve employees or are outdated:

• -processheap
  
• -high
  
• -nod3d9ex
  
• -d3d9ex
  
• -freq [x]
  
• -threads [x]
  
• (commands which belong in the autoexec)

These are the best settings I could find for the least amount of FPS. These settings don't give you the biggest competitive advantage.
You can change your resolution to whatever you want, but a resolution in 4:3 aspect ratio will give you more FPS.

These are the only "useful" console commands that you can use without impacting the gameplay

You can open the console by going into the game options and enable it "Enable Developer Console (~)" then opening it by pressing ~.

These are the best settings for CS:GO that I could find!


Don't choose "Global Settings" but rather "Program Settings" and find csgo.exe, to not mess up your other games.

Skip this if you are playing on a laptop. Go to Windows 10 settings tab > type in "Power" in the search bar > Power & sleep settings > Additional power settings (on the right) > select High Performance

In the search bar again, type: Game Mode > select > Game Mode on

In the same window > select Game bar > Turn it off!

If you got a 144hz monitor, try locking it to 289 (or 300). Aim for double the monitors Hz.
You can do this by typing: fps_max 300 into the console or your autoexec. Don't type fps_max 0, because it prolongs your loading times when hosting an offline match.

NEVER! I mean never vacuum your computer. This could cause an electrical discharge, potentionally destroying your computer.

You should dust your computer every year or so. Piled up dust in your fans can make them go slower and make your computer cooling hotter.
Buy a can of compressed air and remove the cover of your computer. You can also swab the dustiest areas of the computer before bursting the air inside. You should preferably dust your computer outside.
