If a game stutters, check what the PC is doing when it happens. That gives you somewhere to start: a busy game, a background download, and an app using lots of memory need different attention.
Find busy apps in Task Manager
Press Ctrl+Shift+Esc to open Task Manager. On Processes, sort by CPU, Memory, or GPU use; you may need to enable the GPU column. Performance shows the overall readings. GPU information depends on the graphics hardware and driver.
Look once before opening the game, then again while it is running. Watch for an app that starts working at the same time as a slowdown. Save its work before closing it, and test the game again.
Compare the same game scene
A high number alone is not a fault. A demanding game can keep the GPU busy, and loading or shader compilation can use the CPU heavily. Look for a repeatable change that lines up with the problem rather than trying to make every reading low.
Keep the scene, resolution, and graphics settings the same when comparing. Change one thing at a time, such as closing an unused browser. If the result gets worse, put it back.
Check the readings in Game Booster
Jitsumi Game Booster shows CPU and memory use together. GPU load and temperature readings are available on supported NVIDIA systems. These are whole-PC readings, not an FPS counter or proof that the game will run faster.
Use Task Manager when you need to identify a particular app. Game Booster’s monitor is useful for keeping an eye on overall activity while you review its other controls.
