Graphics Processing Unit (GPU)

Correct Answer: RT cores

RT cores are the crucial GPU feature for efficient real-time ray tracing in modern games. Here's why: RT cores, or Ray Tracing cores, are specialized hardware units designed specifically for accelerating ray tracing calculations. Ray tracing is a rendering technique that simulates the behavior of light in a 3D environment, creating highly realistic graphics with accurate reflections, shadows, and global illumination. These cores offload the complex ray tracing computations from the main GPU processing units, allowing for real-time ray tracing performance in modern games. Without RT cores, ray tracing would be too computationally intensive to run efficiently in real-time. As for the other options: CUDA cores are general-purpose parallel processing units in NVIDIA GPUs. While they contribute to overall GPU performance, they are not specifically optimized for ray tracing calculations. Tensor cores are designed for accelerating machine learning and AI computations. They don't directly contribute to ray tracing performance. Shader processors are programmable units that handle various graphics rendering tasks, but they are not specialized for ray tracing calculations and would be less efficient at this specific task compared to dedicated RT cores.

Correct Answer: Improve the PC's airflow and clean the GPU fans

Improving the PC's airflow and cleaning the GPU fans is the most effective solution for overheating issues on a GPU. Proper airflow ensures that the GPU receives adequate cool air, while cleaning the fans prevents dust buildup that can hinder heat dissipation. Lowering the monitor's resolution, closing background applications, or upgrading the CPU do not directly address the root cause of GPU overheating, which is insufficient cooling. These other solutions may provide minor performance improvements but will not effectively solve the overheating problem.

Correct Answer: Upgrade his GPU

Upgrading the GPU is likely the most effective solution to improve gaming performance and increase FPS. The GPU is responsible for rendering graphics and is a key component for smooth gameplay. Adding more RAM can help if the system is running out of memory, but it typically has less impact on FPS compared to the GPU. Increasing the monitor's refresh rate allows for displaying more frames per second, but it doesn't improve the PC's ability to generate those frames. Decreasing the monitor's resolution can boost FPS by reducing the graphical workload, but it results in lower visual quality and doesn't address the underlying performance issue.
