If you're struggling with low FPS in Rainbow Six Siege, you're not alone. Gamers on low-end PCs and laptops often face this issue, making the gameplay experience frustrating. However, there are ways to boost FPS and improve your gaming experience. In this article, we will provide expert tips and tricks to optimize your game settings and hardware, so you can enjoy smooth and seamless gameplay. Whether you're a casual or competitive player, this guide will help you get the most out of your gaming setup.

Adjust the Rainbow Six Siege In-Game Settings

Changing your Rainbow Six Siege settings usually makes the most significant performance improvement for low to mid-end systems. Open up your settings, and make changes according to your system’s specifications. Most of the setting changes showcased are applicable for low-end PCs. In case you experience performance issues while using the recommended system requirements, follow the next steps.

Display Settings

First, we will review the Rainbow Six Siege Display Settings, which can make the most significant performance difference on low to mid-end systems. In the General tab, enable the Display Game Info option, which will show your current framerate, latency, and Rainbow Six Siege version in the lower-left corner of your screen. This will help you determine which tweaks help you out the most. In your Display settings, set the resolution to your native monitor resolution. If you’re using an abnormal screen resolution, as I am, then set it to 1920 x 1080, as it will save you a lot of resources. If none of the following tweaks helped you out as much as you wanted, you can lower this option even more. This will improve your overall performance, but the visual quality will suffer greatly. Below, set the Display Mode to fullscreen. Disable the V-sync option to improve your potential frame rate.

Graphics Settings

In the Graphics tab, set the overall Quality Preset to low or medium, depending on your system’s specs. We prefer to set this option to medium and the Shaders and Reflection Quality options to low. Below, set the Anti-aliasing option to T-AA and set the Render Scaling option to 100%. We suggest you try these options before moving on to the following tweaks to compare how much your performance has increased. In case of subpar performance, you should lower the Render Scaling option to about 75 and try again.

Change the Rainbow Six Siege Process Priority

To further increase the Rainbow Six Siege performance on your PC, we will change the application’s priority compared to other programs running in the background. Right-click your taskbar to open up your Task Manager. In the Processes tab, right-click the Rainbow Six Siege process and select go to Details. In the Details tab, the application should be highlighted. Right-click the game process and set the priority to high.

This will allocate more resources to playing Rainbow Six Siege and should increase your performance, especially if you have other programs running in the background. To reduce the CPU utilization from other programs, we suggest you end some programs from running in the background, which you don't need when playing Rainbow Six Siege. Make sure only to end programs from running, which you know won't break your operating system.

Update Graphics Card Driver

NVIDIA graphics cards can utilize the GeForce Experience application. Click here to download the application to your system. When the download is completed, open up the application, and in the Drivers tab, select Download. This will download and install the latest GPU update and should take a few minutes to complete.

Update Operating System

To optimize your system for performance, you should ensure your operating system is up to date. Search for Update in your taskbar search. In your Check for updates system settings window, make sure to download the latest update and make sure to restart your PC after that the download is completed. This will help you with performance issues.

Disable Xbox Game Bar Recording

Some native Windows 10 settings can reduce your performance while playing Rainbow Six Siege. Disable the Game Bar recording option, as it continuously records your gameplay and audio. In your taskbar search, enter: Game Bar to open the game bar system settings.

Uncheck the recording option. In the Captures tab, make sure to disable the background recording option additionally. These settings will only reduce your performance. If you want to record your gameplay, then we suggest using OBS Studio, or an external capture card if you lack performance.

Adjust the NVIDIA Control Panel Settings for Rainbox Six

Making changes to your NVIDIA control panel can be essential. Change a few options in your NVIDIA control panel to improve your system's Rainbow Six Siege performance. To open your NVIDIA control panel, right-click your desktop and select NVIDIA Control Panel. In your control panel, navigate to Manage 3D Settings > Program Settings.

Select Add a program to customize and add the game from the program list. If you can’t find Rainbow Six Siege in the program list, click Browse. In your file explorer, you must locate the drive and path on which you installed the game and add it to the program list. Ensure that the CUDA setting is set to your primary GPU, set the Power management mode to Prefer maximum performance, and set the texture filtering quality to Performance.

Change the Rainbow Six Siege Graphics Preference

Windows 10 allows you to utilize power user settings, such as your graphics settings. To change your graphics settings, enter Graphics Settings in your taskbar search to open up your native settings. When selecting Browse, your file explorer will open up, where you will have to navigate to the drive and path where Rainbow Six Siege is saved. After adding the program to your graphics settings list, the operating system lets you choose between the following:

Let Windows choose
Power Saving (Usually Intel HD Graphics)
High Performance (Usually, your graphics card(s)
Specific GPU (Choose which GPU to use)

For the most system performance, use the High-Performance option. If your GPU is bottlenecking your performance, you should set it to High Performance.

Graphics Settings > Graphics Preference > High Performance

Troubleshoot Performance Problems

Ensure your Rainbow Six Siege files are up to date and complete. In your Steam library, right-click the application and select Properties. A new window will open, where you must select Verify integrity of game files in the Local Files tab. Redownloading and replacing any missing or corrupted Rainbow Six Siege files will take a minute.

Rainbow Six Siege > Properties > Local Files > Verify Integrity

Delete the Windows Temporary Files

Your hard drive might be cluttered with unwanted files. These files will induce lag if not removed properly. You can delete your temporary files manually or use PC cleanup programs, such as CCleaner. These applications are usually the best choice as they automatically keep your hard drive clean. To manually delete your temporary files, enter %temp% in your taskbar search and hit enter. A new folder will open up. Make sure to delete the content of your temporary files folder.

Sometimes, this can take a few minutes if you haven’t done this before. Some files will most likely stay in your temp folder, as these are still in use by your programs. To completely delete these files, you should also empty your recycle bin.
