Call of Duty: Modern Warfare 3 FPS Increase Guide
This guide will show you how to fine-tune your Windows, in-game settings, and game files to get the best gaming experience in Call of Duty: Modern Warfare 3 with low, medium, and high-end PCs. The guide will help increase the overall FPS and improve the game’s visual clarity and performance.
First, we’ll show you how you can tweak your Windows 10 for a better experience in Call of Duty Modern Warfare 3.
1. Enable Ultimate Performance Mode
Windows OS limits your system to run at a balanced state to save power and keep your computer from overusing resources. However, if you want to play video games such as Call of Duty: Modern Warfare 3 on your PC, you should turn Ultimate Performance mode on to get the maximum output out of your system.
By default, it is set to High-Performance mode. To enable Ultimate Performance mode, you need to unlock it first manually.
To enable and activate Ultimate Performance mode:
1. Type CMD in the Search option> Run Command Prompt (CMD) as an administrator mode.
2. Copy the command below and paste it into CMD, and press enter:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
3. Type Power Plan in the search option> click Edit Power Plan
4. Click Power Options
5. Check the Ultimate Performance option
2. Disabling Visual Effects (For Low and Medium End PCS)
By default, Windows 10 has features and options that increase visual clarity and are optimal for everyday use. However, these features can somewhat affect your PC’s performance. So you can disable these visual effects to increase your gaming performance. As it only increases your Modern Warfare 3 FPS and performance by a small margin, it is recommended not to disable these features on higher-end PCs.
To disable Visual Effects on Windows 10:
1. Type Advanced System Settings in the search option and click on View Advanced system settings
2. Click Settings
3. Click Adjust for best performance> press OK
3. Disable Unnecessary Startup Applications
When you boot your PC, many applications automatically start with your Windows. Most of these applications are there that you don’t even use. So, disabling those applications will save resources from your PC and boost Modern Warfare 3’s performance.
To disable Startup Applications:
1. Right-click on your Windows Taskbar and select Task Manager
2. Go to the Startup tab. Here you will see many applications with Enabled/ Disabled status. You need to find the applications with Enabled status. After that, right-click on the applications you don’t want to start automatically whenever you start your PC and click Disable. It will disable those applications from startup.
However, you can still manually turn on these applications whenever you want to use them.
4. Set Call of Duty: Modern Warfare 3 Graphics Performance Preference to High
Windows 10 has a built-in feature for gamers to get optimal performance while in a game. When turned on, Windows will allocate maximum resources to Call of Duty: Modern Warfare 3. As a result, you can smoothly play the game even if background processes are running.
To set Graphics Performance Preference for Call of Duty: Modern Warfare 3:
1. Type Graphics Settings into the search option and click on it
2. After the Graphics settings window pop up. Select Browse> find the location where you installed Call of Duty: Modern Warfare 3 (For example- D:\Games\Call of Duty Modern Warfare 3)> find Modern Warfare Launcher.exe and select it> click Add
3. After adding Modern Warfare Launcher.exe, Call of Duty: Modern Warfare 2 will pop up under the Graphics performance preference section. Click on Modern Warfare 3 Launcher> Options. A new dialogue box will pop up named Graphics Preference. Here you will select the High-Performance option and press Save.
5. Turn On Game Mode
Game Mode works similarly to High-Performance mode. This mode will allow windows to allocate your computer’s resources appropriately so that you don’t have to face lags and stuttering while playing games.
To turn Game Mode on:
1. Type game mode in the Windows 10 search option and click on Game Mode settings
2. After the Game Mode window opens up, Press the Game Mode option to On.
6. Delete Temp Files
Windows needs to save temporary files to maintain its regular operation. However, after a certain period, it no longer requires the temporary files to function properly, and they become junk files, taking up a lot of disk space and slowing down your PC. As a result, it is recommended that you delete the Temp files regularly to keep your PC clean.
To remove Temp files from Windows 10:
1. Type Run in the Windows search option and click on it.
2. A dialogue box will pop up. Type %temp% in the dialogue box and press enter.
3. After that, the Temp folder will open up. Press backspace on your keyboard or go one page back by clicking the Local folder from the top.
4. After that, select Temp folder> right-click > delete. After that, a confirmation dialogue box will pop up. Press continue. It will delete your temp files from your PC.
Even though Windows 10 has great built-in features and options to optimize your PC for better performance in Modern Warfare 3, it has its limitations. So, these third-party applications can help you fine-tune your PC’s performance to the next level.
Intelligent Standby List Cleaner (For Low and Medium End PCS)
Intelligent Standby List Cleaner, or ISLC, is a great tool to free up your RAM. RAM temporarily stores that information inside its memories when using browsers like Google Chrome or doing other work on your computer. As a result, a massive chunk of your RAM stays occupied, which may result in lag and stutter in Modern Warfare 3, especially if you have a low or medium-end PC with 4, 8, or 12 GB of RAM. So, having ISLC running in your background will help you clean up your RAM without any issues and is entirely safe to use.
To free up your RAM:
1. Download ISLC from here and Install it.
2. Open the ISLC application from your desktop or installation folder.
3. After the application opens up, check the two boxes in the bottom left corner, so the application starts every time you boot your windows.
4. Now, fill up the “Free memory is lower than:” box with half the amount of your ram size. For example, if you have 4 GB ram, fill 2048 MB. For 8 GB ram, fill 4096. I have 12 GB of ram, so I have put 6144 in the box. After that, press start, and you are done.
