GPU Bound (13%) — Ideal Gaming Scenario
Bottleneck (13%) = (1 - min(FPS_CPU:156, FPS_GPU:135) / max(FPS_CPU:156, FPS_GPU:135)) × 100%
The CPU is responsible for game physics, audio, AI routines and preparing the render command buffer (draw calls). The GPU executes the actual vertex, pixel shading and rasterization passes. If you activate DLSS or FSR, the GPU has fewer pixels to shade per frame, so it finishes each frame faster. As a result, the GPU demands draw calls at a higher frequency, causing the bottleneck to shift directly onto the CPU.
Frequently Asked Technical Questions
Is the RTX 4070 Super sufficient for 1440p gaming with Ray Tracing?
Yes, powered by 3rd Gen RT cores and DLSS 3.5. Enabling DLSS Quality drops internal render to 1707x960, sustaining over 80 FPS in Cyberpunk 2077 with full Path Tracing.
