High CPU usage can lead to bottlenecks if the CPU cannot keep up with the demands of the graphics workload.
When a system has insufficient graphics memory, it may cause stuttering or lag during rendering. This occurs because the CPU has to constantly swap data in and out of main memory, which is slower than accessing VRAM. Conversely, if the CPU is heavily utilized, it may delay the processing of graphics commands, impacting frame rates.
According to a study by AMD, systems with balanced CPU and GPU usage achieve optimal performance.
