Microsoft Flight Simulator

The pairing of the Intel Core Ultra 7 165H with the NVIDIA GeForce RTX 4090 produces a highly capable set of results in Microsoft Flight Simulator, placing the combination at rank 614 out of 2996 tested combos. The data reveals a system that can handle the simulator's demanding rendering workloads, though the specific experience varies significantly based on the chosen resolution and quality preset. This analysis examines the measured frame rates to determine the optimal settings, the role of the GPU and CPU, and how the system scales across different resolutions.

Settings Recommendations

The measured data indicates that the Ultra preset is the most demanding option, yielding an average of 92 FPS at 1080p, 74 FPS at 1440p, and 55 FPS at 4K. While these are playable numbers, they represent the lowest performance tier in the dataset. For a simulation title where smoothness and consistency are paramount, the High preset offers a more compelling balance. At 1080p, High settings produce an average of 97 FPS, which is only 5 FPS lower than Ultra but comes with the benefit of reduced rendering load. The advantage of High becomes clearer at higher resolutions: it delivers 78 FPS at 1440p and 58 FPS at 4K, compared to Ultra's 74 FPS and 55 FPS respectively. The performance margin between High and Ultra is narrow, suggesting that the visual fidelity gains from Ultra may not justify the frame rate cost.

The Medium preset emerges as the best overall experience for players prioritizing frame rate stability. At 4K, Medium achieves an average of 77 FPS with a recorded minimum of 65 FPS and maximum of 88 FPS, making it the only 4K setting in the pack that maintains an average above 60 FPS while providing a defined frame time window. At 1440p, Medium produces 104 FPS on average with a minimum of 88 FPS, and at 1080p it reaches 129 FPS with a minimum of 109 FPS. This consistency is critical for flight simulation, where sudden frame drops can disrupt the experience. The Low preset offers the highest frame rates—166 FPS at 1080p, 133 FPS at 1440p, and 98 FPS at 4K—but it likely sacrifices too much visual detail for a game that relies heavily on scenery and terrain rendering.

Given the data, the Medium preset is the recommended choice for this combo. It provides the best balance of visual quality and performance, particularly at 1440p and 4K, where the frame rates remain comfortably high. High settings are a viable alternative for users who prefer more visual detail and are willing to accept a modest frame rate reduction, especially at 1080p where the average stays near triple digits. Ultra should be reserved for scenarios where maximum fidelity is desired and the frame rate targets are flexible, as the data shows it consistently trails Medium by a significant margin—roughly 34% at 1080p, 29% at 1440p, and 29% at 4K in average FPS.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and its specifications underscore its capability to drive Microsoft Flight Simulator at high resolutions. The GPU is built on the Ada Lovelace architecture with a 5 nm process from TSMC, featuring a chip designated AD102. It houses 16,384 shading units, 512 texture mapping units, and 176 raster operation pipelines, along with 128 ray tracing cores and 512 tensor cores. This hardware configuration allows for substantial parallel processing, which is directly relevant to the simulator's complex scene rendering and lighting calculations.

Memory capacity and bandwidth are crucial for Flight Simulator, which streams vast amounts of terrain and asset data. The RTX 4090 carries 24 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 1.01 TB/s. This large memory pool ensures that the GPU can hold extensive texture data without bottlenecks, which likely contributes to the stable performance seen in the Medium preset's minimum frame rates. The memory operates at 1313 MHz with 21 Gbps effective speed, and the GPU's base clock is 2235 MHz with a boost clock of 2520 MHz. These clock speeds enable the GPU to sustain high throughput, as evidenced by its FP32 performance of 82.58 TFLOPS.

The GPU's benchmark scores further illustrate its strength. In 3DMark Steel Nomad DX12, it scores 9,223, while Geekbench OpenCL and Vulkan tests yield 255,416 and 271,631 respectively. Passmark G3D and GPU Compute scores are 38,194 and 26,613. These numbers place the RTX 4090 in the 88th percentile of all GPUs, with an average benchmark score of 60,347. Its nearest rivals include the Intel Arc Pro A60 with a delta of 0%, the AMD Radeon Pro Vega 48 at 0.3% ahead, the AMD Radeon Pro W6600M at 2.5% behind, and the AMD Radeon PRO V710 at 2.9% ahead. The GPU's role is clearly to handle the heavy lifting of rendering, and the measured FPS data shows that it does so effectively, particularly at lower settings where frame rates exceed 130 FPS.

Resolution Scaling

The frame rate data reveals a clear pattern of performance degradation as resolution increases from 1080p to 4K, indicating where the bottleneck lies. At Low settings, the average FPS drops from 166 at 1080p to 133 at 1440p, a 20% decrease, and then to 98 at 4K, another 26% decrease. This substantial drop suggests that even at Low settings, the GPU is being pushed harder at higher resolutions, though the absolute numbers remain high.

At Medium settings, the scaling is more moderate. The average FPS is 129 at 1080p, 104 at 1440p (a 19% drop), and 77 at 4K (a 26% drop from 1440p). The minimum frame rates also scale proportionally, from 109 at 1080p to 88 at 1440p to 65 at 4K. This consistency shows that the system handles the increased pixel load without introducing instability.

High settings exhibit a similar trend: 97 FPS at 1080p, 78 FPS at 1440p (a 20% drop), and 58 FPS at 4K (a 26% drop from 1440p). Ultra settings follow suit with 92, 74, and 55 FPS respectively, showing drops of 20% and 26%. The uniform percentage drops across all settings indicate that the limiting factor scales predictably with resolution, which is characteristic of a GPU-bound scenario. The CPU's role becomes less prominent as resolution rises, but the consistent 20% and 26% drops suggest that the RTX 4090 is the primary driver of performance, and its capabilities diminish in a linear fashion as pixel count increases.

How This Combo Ranks

In the database of tested combinations for Microsoft Flight Simulator, this specific pairing of the Intel Core Ultra 7 165H and NVIDIA GeForce RTX 4090 holds a rank of 614 out of 2996 combos. This places it in the top 20% of all tested configurations, indicating a strong overall performance. The rank reflects the combination's ability to deliver high frame rates across multiple settings and resolutions, as evidenced by the measured data.

The GPU's individual percentile ranking of 88th among all GPUs is higher than the combo's overall rank, suggesting that the CPU may be a slight limiting factor in some scenarios. The CPU's percentile rank is 84th among all CPUs, with an average benchmark score of 34,083. Its nearest rivals include the Intel Core Ultra 5 338H (0.3% higher score), AMD EPYC 4244P (0.4% lower), AMD Ryzen AI 7 350 (0.4% lower), and AMD Ryzen 7 3700X (0.5% lower). This relatively tight grouping indicates that the Core Ultra 7 165H is competitive with its peers, but not a standout performer. The combo rank of 614 suggests that while the RTX 4090 can push high frame rates, the CPU's performance in this simulator prevents the combination from reaching the top tiers, where more powerful desktop CPUs might be paired with the same GPU.

CPU Role

The Intel Core Ultra 7 165H is a mobile processor from the Core Ultra Series 1, built on the Meteor Lake architecture with a 7 nm process from Intel. It features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 5.00 GHz. The CPU's cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. This configuration supports multi-threaded workloads, which is relevant for Flight Simulator's simulation and physics calculations.

In synthetic benchmarks, the CPU scores 14,551 in Cinebench R23 multicore and 1,759 in single-core, while Cinebench R20 scores are 9,233 and 1,303 respectively. Passmark tests show a multithread score of 25,933 and a single-thread score of 3,509. These numbers indicate that the CPU is capable of handling the simulator's background tasks, but its mobile design with a TDP of 28 W may constrain sustained performance under heavy load. The memory support is DDR5 with a dual-channel bus and a bandwidth of 89.6 GB/s, which is adequate for feeding the GPU but not exceptional.

The CPU's role in this combo is to maintain frame rates without becoming a bottleneck, particularly at lower resolutions where the GPU has more headroom. The data shows that at 1080p Low, the system achieves 166 FPS, which is a high number but not the ceiling for the RTX 4090. This suggests that the CPU is limiting the GPU's potential at lower resolutions, as the GPU is capable of much higher frame rates in less CPU-intensive scenarios. However, at higher resolutions and settings, the CPU's impact diminishes, and the GPU becomes the dominant factor. The CPU's 84th percentile ranking and its benchmark scores place it in a competitive position, but it is not a top-tier processor for this specific workload.

Measured FPS Breakdown

The measured frame rates provide a comprehensive view of the combo's performance across all tested configurations.

At 3840x2160 (4K), the Ultra preset yields an average of 55 FPS, with no minimum or maximum recorded. High settings improve the average to 58 FPS. Medium settings produce an average of 77 FPS, with a minimum of 65 FPS and a maximum of 88 FPS. Low settings achieve an average of 98 FPS. The progression from Ultra to Low shows a steady increase in performance, with Medium offering the best balance of stability and speed.

At 2560x1440 (1440p), Ultra averages 74 FPS, High averages 78 FPS, Medium averages 104 FPS with a minimum of 88 FPS and maximum of 119 FPS, and Low averages 133 FPS. The Medium preset at 1440p is particularly strong, delivering frame rates that are smooth and consistent, which is ideal for a flight simulator where precise control is necessary.

At 1920x1080 (1080p), Ultra averages 92 FPS, High averages 97 FPS, Medium averages 129 FPS with a minimum of 109 FPS and maximum of 148 FPS, and Low averages 166 FPS. The 1080p Medium preset offers the highest minimum frame rate in the entire dataset, ensuring a stable experience even during complex scenes.

The data shows that the combo performs best at Medium settings across all resolutions, with the 1080p Medium configuration being the standout for frame rate consistency. The Ultra and High presets are playable but offer lower averages, while Low settings provide the highest frame rates at the cost of visual fidelity. The minimum frame rates recorded for Medium settings at all resolutions (109, 88, and 65 FPS) demonstrate that the system maintains a solid floor, which is critical for avoiding stutters in a simulation environment. Overall, the measured FPS breakdown confirms that this combination is well-suited for Microsoft Flight Simulator, with the Medium preset being the recommended choice for the best experience.
