01 / The problem
A binary "will my PC run this" check tells you nothing useful — CPU/GPU balance shifts per game, per resolution, and per upscaler, not just per hardware tier.
02 / The approach
Built a calibrated Amdahl frame-time model with a per-game cpu_fraction (manually benchmarked or genre-defaulted, not guessed) that splits frame time between CPU and GPU work, then layers on resolution/preset multipliers and DLSS/FSR/XeSS-aware gating.
03 / The catch
The hardware scoring has to stay in lockstep with its sibling site, Bottleneck Calculator — both read the same benchmark API, so a scoring change on one can silently break predictions on the other.
Predicts gaming frame rates for any CPU + GPU combination across 50+ AAA titles using a calibrated Amdahl frame-time model at 1080p, 1440p, and 4K. Built with a FastAPI backend backed by PostgreSQL and Alembic migrations, a React 19 + Tailwind frontend with i18next localisation, and deployed via Coolify blue-green on Docker. Automated with GitHub Actions (pytest).
Highlights
Per-game cpu_fraction, not a generic genre default
VRAM penalty modeling for VRAM-limited scenarios (e.g. 4GB GPU at 4K Ultra)
AEO-optimized — FAQ schema and result prose written for AI search citation, not just Google
Admin dashboard for game CRUD, usage analytics, and CSV export
