Certain games may cause certain issues for the users, especially if the game has not been optimized yet for the PC. Additionally, a lot of users are trying to run a game with high system requirements on a low-end PC resulting in a low-quality performance. Even with all of the graphic settings turned off or set to low, users sometimes still experience a lot of issues and they fail to get a playable frame rate which starts at 25 FPS (frames per second) which is considered to be the lowest acceptable frame rate.

Playing Steam games in Windowed mode sometimes manages to fix certain issues regarding low performance but certain developers have not included this setting in their games and a lot of users are wondering whether there’s a way to make all Steam games start in windowed mode. It turns out there is and there are several ways you can make a game run in windowed mode!

First of all, you check the in-game settings in order to see whether the specific game has a built-in option of playing in a window. These settings are usually located in the game’s video settings. Note that a lot of these settings depend on the mode you play. For example, if you set the fullscreen resolution to 1024 x 768, then the size of your windows is going to have the same dimensions after your turn fullscreen off.

However, certain games simply won’t allow you to switch between fullscreen and windowed mode in-game since there are games which don’t allow a lot of changes to its settings or they must be changed via an external config file. Luckily, the solution to this problem is rather easy and it involves using the Steam client.

The first thing we are going to explain is using the game launch options which allow the users to set a lot of different options before even running the game. In order to set various game launch options, open Steam library and right-click on the game you want to set to windowed mode. Open properties and click Set Launch Options… on the General tab.

If you want to add the windowed mode parameter, you need to type in –windowed in the field that opens. Note that you need to separate this parameter from the others if you have them by a space. A useful parameter to add next to the –windowed one is the parameter which defines the width of the game’s window. If the game starts in fullscreen the following parameter is going to define the resolution of the screen. Make sure you leave one space blank and type in –w <width> where <width> represents the total width in pixels, for example, 1024. There is no need to set the height since the width already determines the matching height.

Unfortunately, users have reported that these launch options only work for games which use Source and Goldsrc engines. If you want to edit another game, you might want to try right-clicking the game launcher’s shortcut and selecting Properties. In the shortcut tab, you should see a field called Target. This field represents the original location of the shortcut. Simply add –windowed or –w after the quotation marks and your game should run windowed.

The last option is to simply try clicking Alt + Enter while in-game.
