Ready Or Not

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5080 delivers a remarkably consistent high-refresh-rate experience in Ready Or Not, but the data reveals that the Ultra preset is the only setting tier that fails to maintain a fluid frame rate at higher resolutions. The measured results indicate that this combination is overwhelmingly GPU-bound at lower settings, with the CPU's six cores proving sufficient to feed the RTX 5080's enormous throughput across most configurations. The sweet spot for this pairing is the High preset at 1440p, which delivers a 244.4 average FPS while maintaining the visual fidelity expected from a tactical shooter. The data shows a clear performance hierarchy across settings, with the gap between presets widening dramatically as resolution increases, pointing to the RTX 5080's massive rendering capacity as the dominant factor.

Settings Recommendations

For the best balance of image quality and performance, the High preset at 2560x1440 is the recommended configuration, delivering a 244.4 average FPS that fully saturates modern high-refresh displays while preserving the atmospheric lighting and shadow detail critical to Ready Or Not's tactical gameplay. The 1080p High setting achieves a 290 average FPS, which offers marginal benefit over the 1440p result unless the user prioritizes maximum frame rates above all else. The Low preset at 1080p produces a 312.6 average FPS, representing the absolute ceiling for this combination, but the visual compromise is substantial for a game where environmental readability matters. Ultra settings should be avoided at 4K, as the 93.5 average FPS dips below the 100 FPS threshold that many players consider essential for responsive aiming in a tactical shooter. Medium settings provide a minor improvement over High at every resolution, with the 1440p Medium result of 254 average FPS representing only a 3.9% gain over High, making the visual downgrade unjustified. The performance scaling from High to Ultra at 1440p shows a 28.5% drop to 174.7 average FPS, indicating that the Ultra preset's additional effects impose a significant cost without proportional visual returns.

CPU Role

The Intel Core i5-9400 contributes six cores and six threads to this pairing, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz, operating on a 14 nm Coffee Lake architecture. The benchmark data shows this processor sits at the 50th percentile among all CPUs, with an average benchmark score of 2305, placing it within 0.6% of the Intel Core i7-8809G and 0.2% of the Intel Core i3-10305. In Ready Or Not, the CPU's role is to maintain consistent frame pacing, and the measured results indicate it succeeds admirably. At 1080p Low, the combination achieves 312.6 average FPS, which implies the six threads are sufficient to process game logic and draw calls without bottlenecking the RTX 5080. The difference between 1080p Low and 1080p Ultra is only 19.7% at 250.9 average FPS, suggesting that even the most demanding preset does not expose a CPU limitation at this resolution. The 9 MB of shared L3 cache and dual-channel DDR4 memory support provide adequate bandwidth for a tactical shooter where scene complexity varies with squad positions and environmental destruction. The processor's 65 W TDP and end-of-life production status indicate it is an older mainstream part, yet the data shows it remains viable for high-refresh gaming in this title.

How This Combo Ranks

This specific configuration achieves a rank of 304 out of 1748 tested combinations in Ready Or Not, placing it in the top 17.4% of all measured pairings. The ranking reflects the RTX 5080's dominant contribution, as the GPU sits at the 89th percentile among all graphics cards with an average benchmark score of 59188, while the CPU's 50th percentile position is comparatively modest. The combination's performance relative to its rank suggests that the RTX 5080 is the primary driver of the high frame rates, with the i5-9400 providing adequate support without significantly dragging down the overall result. In the context of the 1748 combos, a rank of 304 indicates that the pairing outperforms the vast majority of systems, though it falls short of the absolute top tier occupied by newer flagship CPUs paired with this GPU. The measured FPS data confirms that this rank is well-earned, with the combination exceeding 200 average FPS at 1440p across all settings except Ultra. The gap between this combo and higher-ranked alternatives would likely stem from CPU-bound scenarios at lower resolutions, but the data shows the i5-9400 holds its own in Ready Or Not specifically.

Resolution Scaling

The performance drop from 1080p to 4K reveals a predictable scaling pattern that underscores the RTX 5080's role as the limiting component. At High settings, the 1080p average of 290 FPS falls to 244.4 FPS at 1440p, a 15.7% reduction, then to 131.4 FPS at 4K, a further 46.2% decrease from 1440p. This steep decline at 4K indicates that the GPU's rendering workload grows quadratically with pixel count, and the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are being heavily taxed. At Low settings, the scaling is similar: 312.6 FPS at 1080p drops to 264.7 FPS at 1440p (15.3% reduction) and then to 166.6 FPS at 4K (37.1% reduction). The relatively smaller drop from 1440p to 4K at Low settings suggests that the reduced visual effects lower the GPU load enough to mitigate the resolution penalty. The Ultra preset shows the most dramatic scaling, with 250.9 FPS at 1080p falling to 174.7 FPS at 1440p (30.4% reduction) and then to 93.5 FPS at 4K (46.5% reduction). This pattern indicates that at Ultra settings, the combination of high resolution and demanding effects saturates the GPU's capabilities, while the CPU maintains consistent performance across all resolutions.

Measured FPS Breakdown

At 1920x1080, the combination delivers its highest frame rates across all settings: Low achieves 312.6 average FPS, Medium reaches 296.5 average FPS, High hits 290 average FPS, and Ultra drops to 250.9 average FPS. The spread between Low and Ultra at 1080p is 19.7%, indicating that even the heaviest preset leaves substantial headroom. Moving to 2560x1440, the results show 264.7 average FPS at Low, 254 average FPS at Medium, 244.4 average FPS at High, and 174.7 average FPS at Ultra. The Ultra preset at 1440p represents the largest single-settings penalty, with a 28.5% reduction from High. At 3840x2160, the frame rates compress significantly: Low produces 166.6 average FPS, Medium achieves 142.7 average FPS, High delivers 131.4 average FPS, and Ultra falls to 93.5 average FPS. The 4K Ultra result is the only configuration that fails to exceed 100 average FPS, and the gap between 4K Low and 4K High is 21.1%, showing that the GPU's rendering capacity becomes the primary constraint at this resolution. Across all resolutions, the Low-to-High gap narrows as resolution increases, from 7.2% at 1080p to 21.1% at 4K, confirming that the RTX 5080's performance scales with resolution rather than settings.
