Microsoft Flight Simulator

Microsoft Flight Simulator presents an unusually demanding workload that stresses both the processor and graphics card in distinct ways. This analysis examines the measured performance of the Intel Core Ultra 7 270K Plus paired with the AMD Radeon RX 7700, using only the provided benchmark data to interpret how this combination behaves across resolutions and settings. The data reveals a system that scales predictably with graphical load but also shows the significant impact of the CPU in a simulation-heavy title.

Resolution Scaling

The measured frames per second (FPS) data shows a clear and consistent pattern as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average FPS drops from 126 at 1080p to 102 at 1440p, and finally to 75 at 4K. This represents a 40% reduction from 1080p to 4K, indicating that even at the lowest graphical preset, the GPU is still the primary limiting factor at higher resolutions. The step from 1080p to 1440p is a 19% performance loss, while the step from 1440p to 4K is a 26% loss, showing that the scaling is not perfectly linear but consistently negative.

At Medium settings, the same trend holds. The average FPS is 98 at 1080p, 79 at 1440p, and 59 at 4K. The percentage drops are 19% from 1080p to 1440p and 25% from 1440p to 4K. This consistency suggests that the rendering load scales proportionally with pixel count, and the RX 7700’s compute resources are being taxed more heavily as resolution rises. The minimum and maximum FPS recorded at Medium settings also show a wider spread at lower resolutions: at 1080p the range is 84 to 113, while at 4K it narrows to 50 to 67. This tighter range at 4K indicates that the frame pacing becomes more consistent when the GPU is more fully saturated.

High settings show a similar pattern. The average FPS is 74 at 1080p, 60 at 1440p, and 44 at 4K. The drop from 1080p to 1440p is 19%, and from 1440p to 4K is 27%. At Ultra settings, the averages are 70, 57, and 42 for 1080p, 1440p, and 4K respectively. The difference between High and Ultra at each resolution is modest—about 5% at 1080p, 5% at 1440p, and 5% at 4K—suggesting that Ultra settings add a relatively small additional load over High. The overall pattern indicates that the GPU is the dominant bottleneck across all tested configurations, as FPS consistently decreases with resolution regardless of the preset. However, the fact that Low settings at 1080p reach 126 FPS while Ultra at 4K drops to 42 FPS shows the wide performance envelope of this combo.

How This Combo Ranks

The Intel Core Ultra 7 270K Plus and AMD Radeon RX 7700 combination ranks 1324 out of 2996 tested combos in Microsoft Flight Simulator. This places it in the 44th percentile of all tested systems, meaning roughly 56% of tested combinations deliver higher average frame rates in this specific game. The ranking is notably lower than the CPU’s own standing—the Core Ultra 7 270K Plus has a percentile of 96 versus all CPUs in general benchmark tests, and the GPU has a percentile of 58 versus all GPUs. This discrepancy suggests that Microsoft Flight Simulator’s demands are not well served by this particular pairing, or that the game’s engine is sensitive to factors beyond raw compute power.

Looking at the CPU’s nearest rivals provides context for its general performance. The Intel Xeon 6520P has an average benchmark score of 93786, which is essentially identical to the Core Ultra 7 270K Plus’s 93785, with a deltaPct of 0. The AMD EPYC 4564P scores 95183, placing it 1.5% higher, while the AMD EPYC 9175F scores 95615, 1.9% higher, and the AMD EPYC 4565P scores 95764, 2.1% higher. These deltas are small, indicating that in synthetic benchmarks, the Core Ultra 7 270K Plus performs on par with these server-class chips. Yet in Microsoft Flight Simulator, the combo’s rank suggests that this raw CPU strength does not translate into top-tier gaming performance.

The GPU’s nearest rivals in the database show a different story. The AMD Radeon R9 370X has an average score of 15862, just 0.1% higher than the RX 7700’s 15852. The AMD Radeon Pro W5500 scores 15679, which is 1.1% lower, while the AMD Radeon RX 9060 scores 16014, 1% higher, and the NVIDIA GeForce RTX 3060 Ti scores 16129, 1.7% higher. These are all very close scores, implying that the RX 7700 sits in a tightly contested performance band. The combo’s rank of 1324 out of 2996, however, suggests that in this specific game, the pairing does not leverage its components’ general strengths effectively.

GPU Role

The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture with a Navi 32 chip. It features 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 624.1 GB/s. The GPU has a base clock of 1900 MHz, a game clock of 2041 MHz, and a boost clock of 2459 MHz. The memory runs at 2438 MHz with 19.5 Gbps effective speed. These specifications are substantial for a modern graphics card, and the 16 GB capacity is generous for high-resolution textures that flight simulators often use.

In the measured FPS data, the RX 7700 demonstrates that it can handle the game at playable frame rates up to 1440p across all settings. At 1080p, even Ultra settings yield 70 FPS, which is above the 60 FPS threshold often considered smooth. At 1440p, Ultra drops to 57 FPS, which is still playable but begins to show the GPU’s limits. At 4K, the card struggles to maintain 60 FPS even at Low settings, where it averages 75 FPS, but at Medium it falls to 59 FPS, and at High and Ultra it drops to 44 and 42 FPS respectively. This indicates that the RX 7700’s compute throughput, measured at 25.18 TFLOPS for FP32, is sufficient for 1080p and 1440p gaming but not for high-refresh 4K in this title.

The GPU’s pixel rate of 236.1 GPixel/s and texture rate of 393.4 GTexel/s help explain the scaling pattern. As resolution increases, the pixel fill rate becomes more critical, and the data shows that the card’s performance degrades predictably. The presence of 40 ray tracing cores and support for DirectX 12 Ultimate means the card is technically capable of advanced effects, but the measured FPS at Ultra settings (which may include such effects) shows that enabling them comes at a cost. The 16 GB VRAM is unlikely to be a limiting factor at 4K in this game, as the FPS drops are consistent with compute limitations rather than memory capacity issues.

Measured FPS Breakdown

The complete set of measured FPS values provides a detailed picture of performance. At 1920x1080, the Low preset delivers an average of 126 FPS, which is the highest recorded in the entire dataset. Medium at 1080p averages 98 FPS, with a minimum of 84 and maximum of 113. High averages 74 FPS, and Ultra averages 70 FPS. The gap between Low and Medium is 28 FPS, while the gap between High and Ultra is only 4 FPS, suggesting that Ultra offers diminishing returns over High at this resolution.

At 2560x1440, the averages are 102 FPS for Low, 79 FPS for Medium (with a range of 67 to 91), 60 FPS for High, and 57 FPS for Ultra. The difference between Low and Medium is 23 FPS, and between High and Ultra is 3 FPS. The 1440p results show that High and Ultra are nearly identical in performance, both hovering around 60 FPS. This is a critical observation, as it suggests that the GPU is becoming the limiting factor at this resolution, and the extra graphical features in Ultra do not cost much additional performance.

At 3840x2160, the averages are 75 FPS for Low, 59 FPS for Medium (with a range of 50 to 67), 44 FPS for High, and 42 FPS for Ultra. The drop from Low to Medium is 16 FPS, and from High to Ultra is only 2 FPS. At 4K, the card is clearly struggling to maintain high frame rates, with only the Low preset exceeding 60 FPS. The minimum FPS recorded at 4K Medium is 50, which could lead to noticeable stuttering in a flight simulator where smooth camera panning is important.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. For 1920x1080, all presets deliver playable performance, with even Ultra averaging 70 FPS. The data suggests that at 1080p, the High preset at 74 FPS offers a good balance, but Ultra at 70 FPS is also viable if the user prioritizes visual fidelity. The Low preset at 126 FPS is excessive for most monitors, which typically cap at 144 Hz.

For 2560x1440, the High preset at 60 FPS and Ultra at 57 FPS are both acceptable for a flight simulator, which often runs at lower frame rates than fast-paced shooters. The Medium preset at 79 FPS provides headroom for smoother performance, but the visual difference between Medium and High may be noticeable. Given that High and Ultra are within 3 FPS of each other at this resolution, choosing Ultra is recommended if the hardware can sustain it, as the performance cost is minimal.

For 3840x2160, the data shows that only the Low preset at 75 FPS exceeds the 60 FPS target. Medium at 59 FPS is borderline, and High at 44 FPS and Ultra at 42 FPS will likely result in a less smooth experience. If the user insists on 4K, the Low preset is the only choice that provides a consistently high frame rate. However, the step down to Medium at 59 FPS is small, and the visual improvement may be worth the slight performance drop. For users with a 1440p monitor, the High or Ultra preset is the best choice, while 1080p users can comfortably use Ultra.

CPU Role

The Intel Core Ultra 7 270K Plus is a 24-core, 24-thread processor based on the Arrow Lake Refresh architecture, built on a 3 nm process. It has a base clock of 3.70 GHz and a boost clock of 5.50 GHz. The CPU features a large cache hierarchy, including 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. It supports DDR5 memory with a dual-channel bus and a bandwidth of 115.2 GB/s. The processor’s general benchmark scores are strong, with a Cinebench R23 multicore score of 44253 and a single-core score of 2439. Its Passmark multithread score is 68574, and its single-thread score is 5068.

In Microsoft Flight Simulator, the CPU’s role is critical because the game simulates complex physics and AI, which are heavily reliant on single-thread performance. The Core Ultra 7 270K Plus’s boost clock of 5.50 GHz and single-core Cinebench score of 2439 indicate strong per-thread performance, which should help with the game’s simulation logic. However, the combo’s rank of 1324 out of 2996 suggests that the CPU’s capabilities are not fully utilized, or that the game is more GPU-bound than CPU-bound in this configuration.

The CPU’s nearest rivals in general benchmarks are all server-class chips with similar average scores. The Intel Xeon 6520P matches the Core Ultra 7 270K Plus exactly with a deltaPct of 0, while the AMD EPYC parts are 1.5% to 2.1% higher. These differences are negligible in synthetic tests, but in a gaming scenario, the Core Ultra 7 270K Plus’s higher single-thread clock speed should provide an advantage. The fact that the combo ranks in the 44th percentile in this game, despite the CPU being in the 96th percentile overall, points to the GPU as the more significant bottleneck. The RX 7700’s 58th percentile ranking aligns more closely with the combo’s performance, indicating that the graphics card is the limiting component in this pairing.
