Microsoft Flight Simulator

# Microsoft Flight Simulator — AMD Ryzen 7 5800XT + NVIDIA GeForce GTX 1070

This pairing of an eight-core Zen 3 processor with a Pascal-generation graphics card produces a fascinating bottleneck study in Microsoft Flight Simulator. The GTX 1070's age is visible at every resolution, but the Ryzen 7 5800XT's strong single-thread performance keeps the experience from collapsing at lower settings. The measured data reveals a system where the GPU dictates the ceiling at 4K, while the CPU shows it can push well beyond what this graphics card can deliver at 1080p.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, confirming the GTX 1070 as the primary limiting factor. At Low settings, the average frame rate falls from 83 FPS at 1920x1080 to 67 FPS at 2560x1440 — a 19% reduction — and then to 49 FPS at 3840x2160, a further 27% drop. This pattern shows the GPU struggling with the pixel count increase, as the CPU has ample headroom at these settings.

The High preset tells a similar story: 48 FPS at 1080p, 39 FPS at 1440p, and 29 FPS at 4K. The percentage losses are nearly identical to Low, which suggests the scaling penalty is resolution-driven rather than settings-driven. Medium settings follow the same trajectory, with the frame rate dropping from 64 FPS at 1080p to 52 FPS at 1440p and finally to 38 FPS at 4K.

Ultra settings reveal the harshest scaling, starting at 46 FPS at 1080p, falling to 37 FPS at 1440p, and bottoming out at 27 FPS at 4K. The 4K Ultra result is below the 30 FPS threshold that many consider the minimum for playable flight simulation. Notably, the 1080p to 1440p drop at Ultra is only 20%, while the 1440p to 4K drop is 27% — the GPU's memory bandwidth and pixel throughput are clearly being saturated at higher resolutions.

What does this scaling imply? The GTX 1070's 256-bit memory bus and 256.3 GB/s bandwidth are working near their limits at 1440p, and the gap widens further at 4K. The CPU's role becomes more prominent at lower resolutions; the 83 FPS at 1080p Low shows the processor can feed the GPU effectively, but the graphics card simply cannot maintain that pace as pixel count rises.

GPU Role

The GTX 1070 is the decisive component in this configuration. With 8 GB of GDDR5 memory, 1920 shading units, and 64 ROPs, it delivers a passmark G3D score of 13498, placing it at the 47th percentile among all GPUs. Its nearest rivals — the AMD FirePro W5000, NVIDIA Quadro M2000M, NVIDIA Tesla M10, and NVIDIA Tesla C2070 — all sit within a 0.7% deltaPct, indicating this card is firmly in the mid-range tier of tested hardware.

The GPU's clock behavior is worth examining. The base clock of 1506 MHz and boost clock of 1683 MHz are modest by modern standards, but the card's FP32 performance of 6.463 TFLOPS is the more telling metric for a flight simulator that relies heavily on geometry and texture work. The pixel rate of 107.7 GPixel/s and texture rate of 202.0 GTexel/s directly influence how the card handles Microsoft Flight Simulator's dense terrain rendering.

At 4K Ultra, the 27 FPS average indicates the GPU is completely maxed out. The 4K Medium result of 38 FPS with a minimum of 32 FPS shows some stability, but the gap between Low (49 FPS) and Medium (38 FPS) at 4K is a 22% performance hit for one settings tier. This suggests the card's memory bandwidth is a bottleneck when texture quality increases, as the 256.3 GB/s figure becomes insufficient for the higher-resolution assets.

The GTX 1070's DirectX 12 passmark score of 48 is notably low compared to its DirectX 11 score of 100, which is relevant since Microsoft Flight Simulator can leverage DirectX 12. The data implies the card performs better under older API paths, potentially explaining why the High preset at 1080p (48 FPS) is so close to the 4K High result (29 FPS) in relative terms — the GPU is working harder but not proportionally faster.

How This Combo Ranks

This CPU-GPU combination ranks 3069 out of 3714 tested combos for Microsoft Flight Simulator, placing it in the lower 17% of all configurations. This low rank is primarily attributable to the GPU, as the Ryzen 7 5800XT holds an 81st percentile ranking among all CPUs, while the GTX 1070 sits at the 47th percentile among GPUs.

The combo rank implies that most other tested systems outperform this pairing in this specific game. The data shows a significant mismatch: a CPU that benchmarks in the top 20% of all processors is paired with a GPU in the bottom half. The measured FPS confirms this — even at 1080p Low, the 83 FPS average is far below what the 5800XT could theoretically support with a stronger graphics card.

The rank also reflects the game's demanding nature. Microsoft Flight Simulator is known for heavy draw calls and complex scenery, and the GTX 1070's 2016-era architecture lacks the modern features that newer GPUs bring to this title. The 16 nm process node and 7,200 million transistors are dated, and the card's end-of-life production status suggests it was not designed for this game's scale.

What does this rank mean practically? Users with this combo will experience frame rates that are playable at lower settings but will not approach the smoothness of higher-ranked configurations. The 3714 total combos tested means there is a wide range of possible performance, and this pairing sits near the bottom quartile, indicating it is better suited for less demanding titles.

A: Medium at 1440p offers a 52 FPS average with a minimum of 44 and maximum of 60, giving a 16 FPS variance. Low at 1440p averages 67 FPS but has no reported minimum/maximum. Medium provides the narrowest guaranteed range among reported data.

CPU Role

The AMD Ryzen 7 5800XT is a Zen 3 architecture processor on the AM4 socket, featuring 8 cores and 16 threads. Its base clock of 3.80 GHz and boost clock of 4.80 GHz are supported by 32 MB of shared L3 cache, and the CPU's 7 nm process node from TSMC keeps power efficiency reasonable at a 105 W TDP.

Benchmark data shows this CPU is a strong performer. The Cinebench R23 multicore score of 23794 and single-core score of 3359 indicate substantial processing headroom, while the 3DMark 16-thread score of 7683 and 2-thread score of 1879 demonstrate scaling across thread counts. The passmark physics score of 1355 and floating-point math score of 53808 further confirm the CPU's capability in compute-heavy tasks.

In Microsoft Flight Simulator, the CPU's role is evident at lower resolutions. At 1080p Low, the 83 FPS average likely approaches the CPU's frame generation limit, as the GPU is less stressed at this resolution. The jump from 1080p Low to 1440p Low (67 FPS) and 4K Low (49 FPS) shows the GPU taking over as the limiting factor.

The CPU's percentile ranking of 81 versus the GPU's 47 creates a stark imbalance. The nearest CPU rivals — the AMD Ryzen 7 7840H (deltaPct 0), Ryzen 7 8845HS (-0.3%), Ryzen 7 7840HS (-0.3%), and Ryzen 5 9600X (0.6%) — all perform within 0.6% of the 5800XT, confirming this processor is competitive with modern laptop and desktop chips.

The single-thread performance is particularly relevant for flight simulation, which often relies on a primary thread for game logic. The Cinebench R20 single-core score of 1410 and 3DMark single-thread score of 959 suggest the CPU can handle the game's serial workloads, but the overall frame rate is capped by the GPU.

Settings Recommendations

For this combo, the measured data supports a clear recommendation hierarchy. At 1920x1080, the Medium preset offers the best balance, with an average of 64 FPS and a minimum of 55 FPS. The 9 FPS variance between minimum and maximum is the tightest among all settings at this resolution, indicating consistent performance. High at 48 FPS is playable but with less headroom, while Ultra at 46 FPS approaches the edge of acceptable smoothness.

At 2560x1440, the Medium preset again stands out, averaging 52 FPS with a minimum of 44 and maximum of 60. This 16 FPS variance is wider than at 1080p, but the average stays above 50 FPS. Low at 67 FPS is smoother but sacrifices visual quality. High at 39 FPS is borderline, and Ultra at 37 FPS risks noticeable stutter.

At 3840x2160, no setting provides ideal performance. Medium averages 38 FPS with a minimum of 32 FPS, which is the only 4K setting with reported minimum/maximum data. The 32 FPS minimum is below the 30 FPS threshold but not by much. Low at 49 FPS is the only 4K setting above 40 FPS, making it the recommended choice for 4K users.

The data suggests a "best experience" definition of maintaining at least 50 FPS average with minimal frame drops. Under this criterion, 1080p Medium (64 FPS avg, 55 min) and 1440p Medium (52 FPS avg, 44 min) are the top choices. For users prioritizing visual fidelity over frame rate, 1080p High at 48 FPS is acceptable, but the step to Ultra provides only 2 FPS additional loss while adding minimal benefit.

Measured FPS Breakdown

At 3840x2160, the results are: Low averages 49 FPS, Medium averages 38 FPS with a minimum of 32 and maximum of 44, High averages 29 FPS, and Ultra averages 27 FPS. The progression from Low to Ultra shows a 22 FPS drop (49 to 27), with the largest single-step decline being 9 FPS from Low to Medium.

At 2560x1440, the data shows: Low averages 67 FPS, Medium averages 52 FPS with a minimum of 44 and maximum of 60, High averages 39 FPS, and Ultra averages 37 FPS. The total range is 30 FPS from Low to Ultra, with the Medium to High step costing 13 FPS — the largest drop at this resolution.

At 1920x1080, the results are: Low averages 83 FPS, Medium averages 64 FPS with a minimum of 55 and maximum of 74, High averages 48 FPS, and Ultra averages 46 FPS. The Low to Medium drop is 19 FPS, while High to Ultra is only 2 FPS, suggesting diminishing returns at higher settings.

The Medium preset is the only one with complete minimum and maximum data across all resolutions. At 1080p, the minimum of 55 FPS ensures no drops below playable levels. At 1440p, the minimum of 44 FPS is still acceptable. At 4K, the minimum of 32 FPS is the lowest recorded value for any setting, indicating the GPU is at its operational edge.

Comparing settings across resolutions, the Low preset shows the least degradation from 1080p to 4K (83 to 49 FPS, a 41% loss). Ultra shows the steepest relative loss (46 to 27 FPS, a 41% loss as well, but from a lower base). The consistency of percentage losses across settings suggests the GPU's performance ceiling scales uniformly with resolution, independent of graphical complexity.
