The Pixel Math
Moving from 1080p (2.07M pixels) to 4K (8.29M pixels) represents a 4x increase in raw GPU workload. While modern GPUs are efficient, the pure
pixel fill rate requirements often scale linearly. Our estimator uses pure GPU time extraction to ensure that CPU bottlenecks don't skew your
theoretical upgrade path.
VR & Stereoscopic Rendering
Virtual Reality headsets require rendering two distinct viewpoints simultaneously. This stereoscopic overhead, combined with the extremely high
resolutions needed to eliminate the "screen door effect," makes VR one of the most demanding tasks for any PC. Calculations account for both the
increased pixel count and dual-camera rendering.
Upscaling Overhead (DLSS/FSR)
Technologies like DLSS and FSR reduce the internal render resolution to boost performance, but they aren't "free." There is a fixed computational
cost in milliseconds (ms) for the AI or spatial upscaling pass. At very high framerates or resolutions, this overhead can become a significant
portion of your total frame time.
