Step 2: Select Settings, click the General tab, and remove the checkmark next to the “Enable in-game overlay for supported games” box.

Method 3: Enable the Game’s V-Sync


V-Sync assists in matching the refresh rate of your game’s screen to the monitor’s requirements. Since most players choose to disable V-Sync when gaming, it occasionally resolves some serious problems.

If you’re having severe lag or stuttering with Rainbow Six Siege, though, you might try turning it on instead. For some gamers, the solution to their lagging or stuttering problems is to enable V-Sync under the Display settings.

Method 4: Set the CPU’s Priority to High

Many players were able to resolve their Rainbow Six: Siege slowness difficulties by setting the priority to high. This is how you do it:

Step 1: To launch Task Manager while the game is running, simultaneously press Ctrl + Shift + Esc.

Step 2: Select Details and find your Rainbow Six: Siege.exe file. Move to Set priority with a right-click on the main.exe file, then choose High.

Step 2: Choose Open file location when you right-click the.exe game file.

Method 6: Update Drivers

First things first, make sure the network, sound card, and graphics drivers are all up to date. If any of these aren’t, it could result in a bad gaming experience. Make sure the graphics driver is installed. There are two ways to update your drivers.

Option 1: Manual Update

Graphics card manufacturers like NVIDIA and AMD are constantly releasing updated drivers for both older games and recently launched titles to enhance performance and address issues. Therefore, each time your game slows, crashes, or freezes, you might need to check for updates from AMD or NVIDIA and install the most recent driver.

Option 2: Automatic Update

This is the easiest and quickest method to use. It’s easy enough to finish with a few mouse clicks, even if you’re not familiar with computers. We will use one such driver updater software which is a  must have tool for Windows – Advanced Driver Updater . The steps are as follows:

Step 1: Install Advanced Driver Updater after downloading it.

Step 2: Launch the program and click the “Start Scan Now” button.
