Performance Summary
The Ryzen 5 8645HS + GeForce RTX 4090 pairing runs this title with CPU utilization between 43% and 100% and GPU utilization between 58% and 100%. Ryzen 5 8645HS reaches high load in heavier scenarios, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 85% at 1080p to 91% at 4K, while CPU averages move from 81% to 62%.
Load Interpretation
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) Medium, the GeForce RTX 4090 averages 98% usage (95-100%), while the Ryzen 5 8645HS stays at 58% (43-72%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
Resolution Scaling
At 1080p, averages sit around CPU 81% and GPU 85%. At 1440p, that shifts to CPU 79% and GPU 86%, and at 4K it reaches CPU 62% and GPU 91%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
Optimal Settings Recommendation
1440p (2K QHD) Medium is the most balanced preset based on this dataset. It runs around CPU 76% (57-94%) and GPU 92% (87-96%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 5 8645HS remains stable for consistent frame delivery.
Upgrade Insight
Both components are stressed near their limits in the heaviest presets (Ryzen 5 8645HS: 89% avg, GeForce RTX 4090: 98% avg). A targeted upgrade should follow your target resolution: GPU first for higher image quality, CPU first for higher minimum FPS.
