Yes, a GPU (graphics card) can be a bottleneck, particularly when it’s underpowered for the demands of the applications or games you’re running. This often manifests as low frame rates, stuttering, or lag in games or 3D applications. When the GPU can’t render frames as quickly as the CPU can send data, it becomes the limiting factor in your system.Upgrading to a more powerful GPU or lowering in-game settings (e.g., resolution or graphical details) can reduce the strain on the GPU and improve performance.
