Where do your performance estimates come from?

Each GPU and CPU in our database has a numeric performance tier derived from publicly available benchmarks (TechPowerUp, Tom's Hardware, Digital Foundry, Hardware Unboxed, NVIDIA/AMD first-party benchmarks). We then apply per-game multipliers based on real-world testing of how each title scales across hardware tiers.

Are the recommendations generated by AI?

No. Recommendations come from a deterministic, hand-maintained algorithm. The same hardware + game combination will always return the same settings. We chose this approach so results are reproducible, explainable, and quickly correctable when we spot an error.

How accurate are the FPS estimates?

FPS figures are algorithmic estimates, not measurements from a physical test bench. Game patches, drivers, cooling, background tasks, and individual scenes can change actual performance. Use the result as a starting point and verify it in game.

Why does RAM affect the recommendations?

Below 16 GB of system RAM, modern games can stutter even with a strong GPU because the OS has to swap textures and assets to disk. Our optimizer applies a small FPS penalty and downgrades texture quality when you select 8 GB or 12 GB of RAM, since pushing high textures with limited RAM tends to cause hitching.

What is a CPU bottleneck and when does the tool flag one?

A CPU bottleneck occurs when your processor can't feed your GPU fast enough to keep it fully utilized. We flag this when your selected CPU's performance tier is significantly lower than the GPU's tier for the chosen resolution. The Bottleneck Detector also flags VRAM and RAM bottlenecks where applicable.

Why does the tool sometimes recommend Medium textures on a high-end GPU?

Texture quality is gated primarily by VRAM, not raw GPU power. If you have a fast GPU but only 8 GB of VRAM and the game pushes hard on textures (e.g. The Last of Us, Hogwarts Legacy at 4K), we'll recommend a lower texture preset to avoid stuttering and texture pop-in.

How often is the database updated?

We add new GPUs within a few weeks of release and update game profiles when major patches change performance characteristics. If you spot a missing GPU, missing game, or out-of-date recommendation, please use the suggest-a-game form on the homepage or visit our About page.

Does the tool consider monitor refresh rate?

Indirectly. Competitive games (CS2, Valorant, Apex Legends, etc.) are flagged in our database and the optimizer prioritizes high FPS over visual quality for those titles, targeting 144+ FPS at 1080p. For non-competitive titles, the default FPS target is 60 at your selected resolution.

How GameOptimizer Works

How GameOptimizer Recommends Your Settings

Every recommendation on GameOptimizer is the output of a deterministic algorithm that combines four inputs: your GPU performance tier, your CPU performance tier, your system RAM, and the demand profile of the game you've selected. This page explains exactly what those inputs mean, where the data comes from, and how the algorithm arrives at a final answer.

Step 1 — Hardware Tiering

Every GPU in our database is assigned a numeric performance tier from roughly 1.0 (entry-level integrated graphics) up to 10.5 (RTX 5090 / RX 7900 XTX class). Each CPU gets a similar tier reflecting its single-thread performance — the metric that matters most for modern game engines.

These tiers are derived from publicly available benchmarks across multiple sources (TechPowerUp's relative performance index, Tom's Hardware GPU/CPU hierarchy, Digital Foundry comparisons, Hardware Unboxed test suites, and NVIDIA/AMD first-party numbers). We average and normalize across resolutions to produce a single representative tier per part.

Tiers are not perfectly linear — a tier-8 GPU is roughly 2× a tier-5 GPU at 1440p, but real-world scaling depends on the game and resolution. We compensate for this in Step 3.

Step 2 — Per-Game Profiles

Every game in our catalog has a hand-tuned profile that captures:

Demand rating (1–10): how punishing the engine is at maxed-out settings.
Base FPS: the average framerate of a tier-8 GPU at 1080p Medium, used as a normalization anchor.
Upscaling support: whether DLSS, FSR, and/or XeSS are available, and whether frame generation is supported.
Ray tracing support: whether RT is available and how aggressively it taxes the GPU.
Engine quirks: CPU-bound cities (Starfield), heavy VRAM usage (Hogwarts Legacy at 4K), broken Ultra presets (RDR2), etc.
Competitive flag: for esports titles we prioritize 144+ FPS at 1080p over visual fidelity.

Step 3 — FPS Estimation & Setting Selection

We start from the game's base FPS at 1080p Medium and apply multipliers for:

The ratio of your GPU's tier to the reference tier-8 GPU.
The resolution you're targeting (1080p ≈ 1×, 1440p ≈ 0.65×, 4K ≈ 0.4×, before upscaling).
The selected quality preset (Low ≈ 1.4×, Medium ≈ 1.0×, High ≈ 0.8×, Ultra ≈ 0.65×).
Upscaling mode (DLSS/FSR Quality ≈ 1.4×, Balanced ≈ 1.6×, Performance ≈ 1.8×).
CPU bottleneck adjustments when your CPU tier is significantly below your GPU tier.
RAM penalties when below 16 GB.

The optimizer then walks the matrix of {resolution × preset × upscaling} combinations and selects the one that hits the target FPS (60 for cinematic games, 144 for competitive) at the highest visual quality your hardware can sustain.

Step 4 — Bottleneck Detection

Once we've chosen settings, the Bottleneck Detector audits the result for four common failure modes:

CPU bottleneck — your CPU is the limiting factor, especially at lower resolutions.
GPU bottleneck — expected and usually fine; flagged for context.
VRAM bottleneck — your GPU's memory can't hold the recommended texture preset.
RAM bottleneck — system memory is too low to avoid stutter.

When a likely bottleneck is detected, the tool explains which setting category to adjust first. The result is diagnostic guidance rather than proof that a component must be replaced.

Limitations We're Honest About

Estimates assume current drivers, no thermal throttling, and no background load.
We don't model storage speed — a slow HDD will hurt texture streaming in some games regardless of GPU.
Game patches occasionally invalidate profiles; we update them as quickly as we can.
Frame generation FPS numbers reflect smoothness, not input latency. Use the latency-mode toggle in-game.

Research and review policy

GameOptimizer Editorial checks official requirements, vendor documentation, public benchmark suites, and technical references before publishing an indexed game profile. Algorithmic FPS figures are labeled as estimates and are not presented as measurements from a physical test bench.

Profiles are reviewed after major game patches or hardware-generation changes. Pages without enough distinct, supportable analysis remain usable inside the tool but are excluded from search until reviewed.

Primary references include official publisher support pages, GPU vendor documentation, TechPowerUp's relative-performance database, and PCGamingWiki's technical notes. Affected game guides also list page-specific sources.
