Rust

The Intel Core i5-11400F paired with the NVIDIA GeForce GTX 1660 Ti produces a playable but constrained experience in Rust. The data shows this combination ranks 1470th out of 1717 tested combos for this game, placing it in the lower half of the performance spectrum. The measured FPS results reveal a system where the GPU becomes the dominant bottleneck at higher resolutions, while the CPU's six cores and twelve threads provide a solid foundation that keeps frame rates viable at lower settings. This analysis walks through the measured data to interpret what these numbers mean for actual gameplay.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, indicating that the GTX 1660 Ti is the primary limiting factor in this pairing. At Low settings, the average frame rate falls from 107.6 FPS at 1920x1080 to 75.2 FPS at 2560x1440, a reduction of 30.1%, and then further to 43.4 FPS at 3840x2160, which is 59.7% below the 1080p baseline. The pattern holds at Medium settings: 74.7 FPS at 1080p drops to 47.7 FPS at 1440p and 30.5 FPS at 4K. This scaling behavior is characteristic of a GPU-bound scenario, where the pixel throughput demands of higher resolutions overwhelm the 6 GB GDDR6 memory and the 288.0 GB/s bandwidth.

At High settings, the trend continues with 59.1 FPS at 1080p, 43.9 FPS at 1440p, and 27.5 FPS at 4K. The Ultra preset tells a similar story: 47.3 FPS at 1080p, 30.7 FPS at 1440p, and just 19.1 FPS at 4K. The consistent proportional drop across all presets suggests that the GPU's computational resources—its 1536 shading units and 48 ROPs—are saturated regardless of the visual complexity. The data indicates that 1440p is the practical ceiling for smooth gameplay, while 4K is only viable for Low settings, and even then, the 43.4 FPS average is below the 60 FPS target most would prefer.

The scaling from Low to High at 1080p shows a 45.1% performance penalty, from 107.6 to 59.1 FPS, which is a far smaller relative drop than the resolution scaling. This implies that while the GPU is stressed by higher resolutions, the CPU, with its 12 threads and 12 MB of shared L3 cache, has enough headroom to support lower-resolution, higher-frame-rate scenarios. The measured data suggests that for users prioritizing frame rate, staying at 1080p with Medium settings offers the best balance of visual quality and responsiveness.

Settings Recommendations

The measured data points to 1920x1080 with Medium settings as the optimal combination for this hardware. This preset delivers 74.7 FPS on average, which is comfortably above the 60 FPS target for competitive play, while offering a meaningful visual upgrade over Low settings. The jump from Low to Medium costs 32.9 FPS (from 107.6 to 74.7), but the visual fidelity gains are substantial in Rust's open-world environments where draw distance and texture detail matter.

For users who prioritize frame rate above all else, 1080p Low at 107.6 FPS is the clear choice. This configuration provides a significant margin over the 60 FPS baseline, which could be beneficial in PvP scenarios where responsiveness is critical. However, the visual compromise may be too steep for some, as Low settings strip away much of the game's atmospheric detail.

At 1440p, the data suggests Medium settings at 47.7 FPS is the most balanced option, as it avoids the harsh visual penalties of Low while staying within playable territory. Users with 1440p monitors should avoid Ultra, which at 30.7 FPS approaches the lower bound of what is considered playable. For 4K displays, the data indicates only Low settings at 43.4 FPS is viable, and even then, the experience will be subpar. The recommendation is clear: stick to 1080p for the best balance, or drop to 1440p Medium if resolution is a priority.

Measured FPS Breakdown

At 1920x1080, the full range of settings produces a wide spread of results. Low settings achieve 107.6 FPS average, which is the highest measured frame rate in the entire dataset. Medium settings drop to 74.7 FPS, High falls to 59.1 FPS, and Ultra bottoms out at 47.3 FPS. The spread from Low to Ultra is 60.3 FPS, demonstrating the significant performance cost of higher presets.

Moving to 2560x1440, the pattern shifts. Low settings still lead with 75.2 FPS, followed by Medium at 47.7 FPS, High at 43.9 FPS, and Ultra at 30.7 FPS. The gap between Low and Medium widens to 27.5 FPS, indicating that the GPU's resource limits begin to bind more tightly at this resolution. At 3840x2160, all settings fall below playable thresholds: Low at 43.4 FPS, Medium at 30.5 FPS, High at 27.5 FPS, and Ultra at 19.1 FPS.

The data reveals that at 1080p, the CPU and GPU work in reasonable balance, allowing Low settings to nearly double the frame rate of Ultra. At 1440p, the GPU becomes more constrained, compressing the performance gap between Medium, High, and Ultra. At 4K, the GPU is fully saturated, and even the difference between Low and Medium (12.9 FPS) shows how little headroom remains. The measured numbers underscore that this hardware is best suited for 1080p and entry-level 1440p gaming.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is the decisive factor in Rust's performance profile. With 6 GB of GDDR6 memory on a 192-bit bus, the card delivers 288.0 GB/s of bandwidth, which is sufficient for 1080p but becomes strained at higher resolutions. The GPU's base clock of 1500 MHz and boost clock of 1770 MHz drive its 1536 shading units, 96 TMUs, and 48 ROPs. The memory runs at 1500 MHz (12 Gbps effective), which is a significant contributor to the card's overall throughput.

The GPU's benchmark scores contextualize its performance. It achieves a PassMark G3D score of 12871 and a Geekbench OpenCL score of 60863, with a Vulkan score of 58014. Its 3DMark Steel Nomad DX12 score of 1061 is a more gaming-specific metric. The card's average benchmark score of 13925 places it in the 55th percentile of all GPUs, meaning it performs better than just over half of tested graphics cards. Compared to its nearest rivals, the GTX 1660 Ti is essentially on par with the AMD Radeon RX 570X (0.4% faster) and NVIDIA GeForce GTX 680 (0.8% faster), while trailing the NVIDIA Tesla K10 by 0.7%.

In Rust specifically, the GPU's role is evident in the resolution scaling. The FPS drop from 1080p to 4K is steep and consistent, reflecting the card's inability to maintain high pixel throughput at 4K. The 6 GB VRAM is adequate for 1080p and 1440p textures, but the 48 ROPs limit fill-rate intensive scenes. The Turing architecture, built on TSMC's 12 nm process with 6,600 million transistors, provides solid DX12 (12_1) support, which is relevant for Rust's modern rendering path.

CPU Role

The Intel Core i5-11400F provides the processing foundation for this combo, with 6 cores and 12 threads running at a base clock of 2.60 GHz and a boost clock of 4.40 GHz. This Rocket Lake chip, built on Intel's 14 nm process, features 12 MB of shared L3 cache and 512 KB of L2 cache per core. Its memory support for DDR4 in dual-channel configuration yields 51.2 GB/s of bandwidth, which pairs adequately with the GPU's 288.0 GB/s.

The CPU's benchmark results show a balanced profile. It scores 14372 in Cinebench R23 multicore and 2029 in single-core, with a Geekbench multicore score of 7579 and single-core of 1979. Its PassMark multithread score is 16908, with a single-thread score of 2981. In 3DMark tests, it achieves 5652 with max threads and 868 single-thread. These numbers place the i5-11400F in the 75th percentile of all CPUs, indicating it outperforms three-quarters of tested processors.

The CPU's nearest rivals show its competitive position. It is essentially tied with the AMD Ryzen 7 5700U (0% delta) and within 0.2% of the Intel Core i7-1260P and Intel Core Ultra 7 164U, while being 0.2% ahead of the Intel Core i5-1240U. In Rust, the CPU's role is to handle the game's simulation and physics, which the 12 threads manage effectively. The measured data shows that at 1080p Low, the system reaches 107.6 FPS, suggesting the CPU can feed the GPU adequately at lower resolutions. The CPU's boost clock of 4.40 GHz is crucial for single-threaded game logic, and its 12 threads prevent multi-threaded bottlenecks in complex scenes with many entities.
