In this section I'll show you step by step how to increase your FPS in Dota 2.



I.Turning off Steam Overlay can greatly improve FPS.

Enter r_dota_disable_portrait_world_renderer 1 to the in-game console.




II.Turn off Windows theme.

Control Panel -> System -> Advance system settings -> Advance tab -> Performance settings -> Visual effects tab -> Choose Adjust for best performance





III.Set your Power Plan for Best Performance.

Control Panel -> System and Security -> Power Options



NOTE:
1.Restart Dota after each match to reset the game memory.
2.Make sure to run only Steam and Dota2, no other background processes.




IV.Setting for NVIDIA GPUs High-end
Open NVIDIA Control panel and Manage 3D Settings page.
Right Click Desktop -> NVIDIA Control Panel -> Manage 3D Settings.
Add Dota 2 as a program in the list, unless it is already there and change the settings to match these.



AMD CPUs
Turn off Turbo Core Control.
To disable it go to BIOS or download AMD Overdrive[www.amd.com] and on tab Clock/Voltage untick the "enable Core Control".
If you use the OverDrive you will have to do it manually after each restart of PC.



Low-end GPUs:
If you have a weak system that can't touch 60fps with everything on low and <720p resolution, I suggest using fps_max 30 console command.

1.Click on the Action center icon next to the clock in Windows (taskbar),click on the "Expand" and turn off the "Location" feature.



2.Exclude the Steam folder from Windows Defender.
(add it as exclusion)




3.Disable Steam Beta participation:
Steam settings -> Account -> and select NONE beta participation




4.Check whether the Workshop update is stuck on downloading page of Steam, if so, reinstalling steam fixes the problem.


5.Enable streamlined push to talk.
You can find this in the game in Audio settings.



6.Check Task manager for processes you don't need and remove them.

1.Disable Xbox application in Windows that may cap the FPS in all games to 60.

• Start an Administrative Powershell window
  
• Run the command 'Get-AppxPackage | Select Name,PackageFullname' (This will list installed Metro apps displaying the Name and PackageFullname needed to uninstall)
  
• Locate the two Xbox packages (Microsoft.XboxLIVEGames and Microsoft.XboxApp)
  
• Copy the 'PackageFullname' from one of these
  
• Type 'Remove-AppXPackage <PackageFullname>' (replace <PackageFullname> with the text you copied from the list) and hit enter
  
• Repeat step 4 & 5 for the other Xbox metro app
  
• Reboot and the Xbox integration will be gone from Full screen games and the Start menu

2.Set fps_max in console to 120

3.Turn off the VSync.

Put engine_no_focus_sleep 0 to your autoexec / console.

Switch from exclusive fullscreen to borderless windowed. It will reduce FPS on slower PCs.

To find out your Graphic card-
go to Control Panel -> Hardware and Sound -> Device Manager -> Display Adapters.
Then make sure you have the latest driver version.



Open Nvidia Control Panel -> Click Use the advanced 3D image settings -> And then click Take me there





1. First, right click on the desktop and left click on AMD Catalyst Control Center.
2.Click on 3D Application settings direclty above the AMD CrossFireX menu option. Then under application settings, click on "+ Add."

Options are available in Steam games library. Go to Steam Games Library -> Right Click Dota 2 -> Properties -> Set Launch Options.
