Find out exactly how to make Roblox run better on your PC.
We check your hardware automatically and give you a checklist built for it. Takes 10 seconds. No download.
Check My SetupMost Roblox lag is not your internet. It is Windows settings that ship wrong for gaming — the power plan that throttles your CPU, the Xbox Game Bar recording in the background, the fullscreen optimizations that add input lag instead of removing it. These are fixable in minutes.
We run a quick graphics benchmark in your browser, read your GPU name and core count, and build a checklist for your specific hardware. A player on an Intel UHD 620 laptop needs different fixes than someone on an RTX 3060 desktop. Generic guides miss that. This one does not.
Everything here is a Windows-level change. We do not modify Roblox files, do not run scripts, and do not ask you to install anything. You follow steps. You see results.
Game guides
Each game has different performance problems. These guides explain the cause and the fix.
How it works
Three things happen before you see your checklist.
Your browser runs a graphics test. We render 300 spinning objects in a hidden canvas for 2.5 seconds and count the frames. This gives a real performance score that reflects how your hardware actually behaves under load — not just what the spec sheet says.
We read your hardware details. GPU name via WebGL, CPU core count, approximate RAM, and whether you are on a laptop or desktop. This happens automatically in under a second and requires no permissions.
You get a checklist for your setup. If you have an integrated Intel GPU, you see the integrated GPU fixes first. If you have NVIDIA, you see the NVIDIA Control Panel steps. The checklist is ordered by impact. Work from the top.
If detection fails — some browsers block hardware queries — you answer three questions and get the same result.
