Discussing CPU and GPU collaboration.
It depends on how the game uses the hardware. Some games rely mainly on the GPU, so boosting its performance makes a big difference. Others depend more on the CPU, and you might need to upgrade it or tweak settings. The difference isn’t just about what each part can handle, but how efficiently they work together.
The video card driver relies on the CPU to process data coming from the game engine and convert it into formats compatible with the graphics card. Certain tasks run in a single thread, using just one CPU core, and increasing their speed makes them noticeably quicker. In short, higher CPU speeds during overclocking allow the GPU driver to handle work more efficiently, delivering frames faster and improving overall performance.
It's unusual for the game to run at 100% GPU usage while the CPU stays low. Overclocking the CPU might help, but if the CPU usage remains minimal, the GPU workload could still be the main factor affecting performance.
It seems you're pointing out that your hardware isn't constrained by the GPU. Just because you're using it at full capacity doesn't mean you're limited by it. Having details about your specs and the game would help clarify the situation.
Games rely on the CPU for multiple tasks such as *compressing background music for game levels and preparing/loading sound effects as required * extracting textures from game files ahead (preparing assets for moments like turning a corner or entering a building), converting them into various formats needed (for instance, a game might only store a 4K texture for ultra-high quality, but at medium-high settings it won’t upload that 20 MB file, instead resizing it to something like 1K and 2-4 MB * these changes can happen inside the graphics card but aren’t always possible) * determining paths and obstacles (where your character can move on the map) for you and other characters * recalculating lighting and shadows whenever the game environment shifts (such as weather effects or level destruction) * executing scripts for NPCs (basic AI, moving NPCs around, initiating conversations between them, relocating them) * in multiplayer scenarios, the CPU also handles calculations and adjusts based on your latency (the time it takes data to reach the server or other players and return)* and many more functions. If a game uses minimal CPU for these processes (NPCs, AI, bots competing against you, crowds, enemies), the CPU is still involved via the video card driver and direct-x/OpenGL, acting as an intermediary between the game and the GPU (Vulkan offers more direct communication but still requires some support). The graphics driver communicates with the GPU through PCIe lanes, transferring data to the card, downloading from its VRAM to free space for other tasks (some games require more VRAM than available). Increasing CPU speed can slightly improve how quickly the driver interacts with the GPU and back, potentially boosting frame rates even when the game isn’t heavily CPU-dependent.
