About Gaming Performance Calculator
Free PC gaming performance and bottleneck estimator. Analyze resolution scaling impacts from 1080p to 1440p and 4K, predict frame rate multipliers with DLSS/FSR/XeSS upscaling modes, and calculate required GPU VRAM budgets.
Key Capabilities & Features
- Projects performance gains across DLSS / FSR Quality, Balanced, and Performance modes
- Estimates GPU VRAM memory footprint across resolutions and texture quality tiers
- Diagnoses CPU-bound vs GPU-bound pipeline bottlenecks
- Actionable recommendations to balance visual fidelity and frame rate

Frequently Asked Questions
How much FPS does DLSS or FSR actually give?
DLSS or FSR Quality mode typically boosts frame rates by 35% to 45% by rendering at ~67% base resolution and upscaling with AI reconstruction, with Performance mode yielding up to 2x FPS in GPU-bound scenes.
How do I know if my PC is CPU bottlenecked or GPU bottlenecked?
If lowering graphics settings or resolution does not increase your frame rate, or if GPU utilization sits below 90% while in game, your CPU is bottlenecking frame delivery.
