Roblox is a popular online gaming platform that provides its players a vast collection of immersive games. However, many players have reported experiencing lag issues that can greatly hinder their gaming experience. If you're one of them, don't worry! This article will show you how to fix lag and boost FPS in Roblox. You can enjoy smooth and seamless gaming on Roblox by following the simple steps outlined below. So, let's get started!

Adjust Roblox Graphics Settings

First, we will take a look at your in-game graphics settings. Launch Roblox and open up your settings. Set the Graphics Quality option according to your PC’s performance. Low to mid-end PCs should set this to around 3 or 4 ticks. Set the Graphics Mode option to Manual to change your quality settings below.

I’d suggest enabling the Performance Stats option, which will show your memory usage, CPU, GPU, and network-related stats, such as your ping to the Roblox server. This can help you out a lot in troubleshooting performance and network issues.

Change Roblox Process Priority

After applying your settings, leave the game running and open up your task manager. In the Processes section, right-click the Roblox Game Client process and click on Details. In the Details tab, the RobloxPlayerBeta.exe process should be highlighted. Right-click the process again and change its process priority to High. This should help maintain a higher frame rate when other resource-intensive applications run in the background.

Task Manager > RobloxPlayerBeta.exe Priority > High

You can then head back to the Processes section to end some CPU, GPU, or memory-intensive processes from running in the background. In my case, this would be my browser, Adobe applications, or Steam.

Make sure not to end processes that could break your operating system. When this is done, you can close the game and your task manager.

Windows Display Settings

Next, open up your Windows settings. Under System, click on Display. Make sure that your main monitor, on which you’re playing Roblox, is selected. Scroll down and set the Scale and Display resolution to their recommended values. This is especially important if you’re using an abnormal screen resolution, as I am, and can already fix performance-related problems with the game.

In your Advanced display settings, ensure that you are using the highest possible refresh rate for your monitor to prevent losing out on frames while in-game.

Windows Settings > System > Display > Advanced

Change Roblox Graphics Preference

Under Related Settings, click on Graphics. Here, you’ll be able to assign a graphics preference for applications and games when they are running on your PC. To add Roblox, click on Browse, which will open up your file explorer.

The default install location for Roblox is in your Program Files > Roblox > Versions. Select the latest folder in this list and click on RobloxPlayerBeta before adding it to the list of applications.

Program Files > Roblox > Versions > RobloxPlayerBeta

Next, click on Options for the game and set your graphics preference to High Performance. This will ensure that your graphics card gets utilized as soon as you launch the game.

Use Windows Game Mode

When this is done, you should enable Windows Game Mode. In the Gaming section of your settings, click on Game Mode. Here, enable Game Mode, which will disable some Windows services from running while in-game and prevent apps from showing an overlay.

Windows Update

In the Windows Update tab, download and install the latest update before restarting your PC. This will ensure that you’re running the latest Windows version, which can improve your performance, depending on how often you update your OS.

Update Graphics Driver

When this is done, you should also ensure that your graphics card driver is up to date. AMD users should make use of the AMD Radeon Software. If you have an NVIDIA graphics card, then you can use the GeForce Experience application.

Open up the application. In the Drivers section, proceed to download the latest driver. GeForce Experience will automatically install the driver, which should only take a few minutes to complete.

Enable NVIDIA Image Scaling

While in your GeForce Experience application, navigate to your settings. You can follow along using the AMD Radeon Software, as both applications are similar.

In your General settings, scroll down and ensure that the Image Scaling option is enabled. NVIDIA Image Scaling, or NIS, will allow you to run the game in a lower resolution, and your graphics card will then help upscale the resolution with minimal effort. This has helped boost frame rates for many users playing any game on their PC, and I strongly recommend playing around with these values until you find a good middle ground. Setting the Render Resolution to 77% and Sharpen to 19 produces the best visual quality while saving on VRAM and other resources when playing Roblox.

GeForce Experience > Settings > General > Image Scaling

Update Additional Windows Drivers

To get the most out of your PC’s components and peripherals, it’s suggested to update additional drivers from time to time.

In your Device Manager, expand your Disk drives, Display adaptors, Monitors, Network adapters, and Universal Serial Bus controllers. For each, right-click the device you are using and select Update driver. On the next window, select Search automatically for drivers.

There are several factors that can cause lag in Roblox, including slow internet speed, outdated graphics card drivers, too many applications running in the background, and more.
FPS (frames per second) is a measure of how smoothly a game runs, while lag refers to any delay or interruption in the gaming experience.
