Age of Empires III: Definitive Edition How to Fix the Low Performance

Age of Empires III

For Age of Empires III: Definitive Edition players, if you are having a low performance(low FPS) while playing ,try some methods provided in this guide, this might solve your problem.

I have specs way over the recommended, but still had issues with loss of FPS during gameplay. And I had no effect by changing the graphic settings. It seems to be something related to Windows 10, but this is just a guess. Follow the list below, and see if you get the same result as me!

Btw. I don’t know if it is just one of these steps that solve the loss of FPS, but by following these steps I have no more issues. I have posted this on the forum at ageofempires-com. One person actually reverted the steps, and still have no issues with performance.

1) Turn off Windows 10 game mode!

  • Click the Start icon to bring up the Start menu, then open the «Settings».
  • Click the «Gaming»
  • On the «Game Bar» tab, set the «Record game clips, screenshots and broadcast using Game bar» to «Off».
  • On the «Captures» tab, set the «Record in the background while I’m playing a game» to «Off».
  • On the «Game Mode» tab, set the «Game Mode» to «Off»!

If you are using and older version of Windows 10, you may not see the Game Mode settings. In this case, you can configure the settings directly in the Registry!

2) Full-screen Optimizations & High DPI in Windows 10

  • Go to the folder where the game is installed:
  • C:\Program Files (x86)\Steam\steamapps\common\AoE3DE
  • Right-click on the game’s exe-file (AoE3DE_s.exe)
  • Hit the Properties
  • Tick «Disable Full-screen optimizations» on the Compatibility tab
  • Click on the «Change high DPI settings» button
  • Under the «High DPI scaling override» section, tick the «Override high DPI scaling behavior»
  • Use the «Scaling performed by:» drop-down meny and select the «Application»
  • Click on the OK and again OK.

3) Windows Performance Options

  • Type «performance» in the search section of Windows, click to «Adjust the appearance and performance of Windows» from the results.
  • Select the «Adjust for best performance» from the options in the Performance Options window that opens.
  • Click «OK»

4) Increase priority in Windows 10
If this makes a difference for you, like me, then you’ll need to adjust this setting every time you enter the game

  • Launch the game.
  • Simultaneously press the ALT and TAB keys to minimize the game.
  • Open the Task Manager
  • Click on Details Tab
  • In the list, find the game’s exe
  • Right-click on the exe-file and Set priority to High

IF you facing stuttering issue in the game after doing this, don’t do the High priority setting. Set it to Normal.

5) Antivirus – add an Exception
In your Antivirus program, make sure this folder path is in the Exception list:
C:\Program Files (x86)\Steam\steamapps\common\AoE3DE
