[b[Everyone has different computers, someone has a powerful processor, someone has a video card, and someone has both, but we will consider an option where you do not lose anything, but you feel an increase.

We do the following:
1) First of all, you need to free up memory as much as possible. Turn off everything you don't need, for example: browser, torrent, etc.

2) Go to Steam\steamapps \common\dota 2 beta\dota\ cfg and look for a file called "video.txt ",we are looking for the value "setting.mat_queue_mode" "digit?" there
I explain what these numbers mean:
The value "1" if this value is worth it, then immediately change it to another one, if you have a weak processor, then this will heavily load it.
The value "-1" disables multi-core mode (for a processor with one core, just right
The value "2" includes 2 cores in the game, making them work at full capacity. If there are 4 cores, then we write the number 4 there, and so on.
Important!

3) In the launch parameters of dota 2, we must specify the following:
-console -novid -high dx_level 81 and the most delicious is threads and the number of cores , let's say 2 cores, which means threads 2 .The fact is that in dota 2, your cores are not fully loaded as they should be, and although dota does not depend much on the processor, you will feel FPS, about 20-30, maybe more.
-dx_level 81 will give a more or less pleasant increase (also without loss of graphics) on an average video card.
-high will give a smoother game without drawdowns (stable FPS)
Everything else that you write in the startup parameters will not give any increase in FPS.

4) Open the task manager and look for a task in the processes such as steambhelper.exe
We close 1-2 such processes, but only those who use more than 120-130 megabytes of memory. If you close more, it will start all over again, automatically.
Important!
If these processes consume no more than 100mb of memory, then there is no point in closing them.

5) nvidia graphics card settings
go to the control panel / nvidia control panel / adjust image settings with viewing / user settings with an emphasis on "performance", that is, pull the slider to the left until it stops. (Some video cards consider themselves "powerful" and put balance or quality, do not believe such video cards, they all lie) :)[/b]
