Before these tweaks my FPS was at 50-60. And it dropped to about 15 frames every 5 or 10 seconds. We can't let that happen, can we? After applying these tweaks i got 80-120 on my old, secondary PC. And it's specs... are pretty bad.

Also, before we start, MAKE SURE you updated your graphic card drivers and every other little thing - if issues are still there - proceed.

Sooo... let's get started!
Cleanup!
First thing we are going to do is clean up and reset every setting in our game.

Before we do it, let's do a backup of two files - config.cfg and video.txt. Also, keep your binds in autoexec.cfg (well, you can name it whatever you want, we'll exec it later).

To do it, go to your CSGO directory (STEAMDIR\steamapps\common\Counter-Strike Global Offensive\csgo\cfg).

Backup these files or delete them completly:

If you're low on space you can also clean your /cache/ folder - you can find there not-completed downloads of maps or sounds from community servers.

So, what did you we do?

We reseted whole game to the default state - also the lowest graphical options possible. As the settings goes - you can configure it whatever you want, but if you want more fps i'll advise keeping low graphic settings. Well, you can change resolution (or you like playing on 640x480...)
Take care of your Audio-Software
Counter-Strike: Global Offensive have some serious problems with... audio. Source isn't optimized for a lot of audio channels at same time (just join DM server, 24 players shooting at once can cause nice stutter).

So, if you're using some software for your headset - for example drivers for Steelseries headsets or Soundblaster for Creative ones or Razer Surround.. Make sure to DISABLE every function - equalizer, surround or every other thing. I assure you you will get quite nice FPS boost.
Before we launch our game...
Wait, that's not everything! Another thing that will help us get some more fps is tweaking our launch command line.

You can find it under "Proporties" on your list. Just right click on Counter-Strike: Global Offensive.

And set it up like this:

-novid -nod3d9ex -threads x (x is numer of your cores) -high

Let's run down these commands:

novid - it disables the intro, pretty useful
nod3d9ex - disables some external effects of DirectX - give you more FPS
threads x - threads of your processor (if you dont know it, use core number)
high - sets high priority to CSGO process

There is one more command that's not advised to use, as it was fix to issue that was patched long ago. However, if you get constat FPS spikes every 5 seconds and didn't try it yet - you might as well do it.

-processheap is the command. However, before using it you should check if your PC isn't overheating.

Last thing you need to do is check programs that round in background. You easily do that by opening your taskmangager (right-click on taskbar or CTRL+ALT+DELETE).

Watch out for processes with high CPU usage. And in this category winners are... browsers and anti-virus programs.

Edit: After thinking about it I recommend turning the DVR feature off BEFORE you follow my steps! It may or may not be an option that is only set by the Xbox app, but the DVR stuff could be executed by some driver or so. No Xbox app, no turning off the "feature" anymore.
Another user has posted the registry keys to turn it off without the app if you already uninstalled.

Start - Type "power" - Right Click on "Windows Powershell" - Run as Administrator Enter the command
Get-AppxPackage *xboxapp* | Remove-AppxPackage
and press Enter
If there's an error, just ignore it. You can check if the XboxApp is still installed with the command
Get-AppxPackage *xboxapp*
(in the same window, press enter afterwards)
If there's no output, i.e. no list of installed apps being displayed everything went fine.
