Resolution Scaling

The measured frame rates show a steep and consistent penalty as resolution climbs, which points squarely at the GPU as the limiting component in this pairing. Moving from 1920x1080 to 2560x1440 at High settings drops the average from 50.9 FPS to 41.6 FPS, a loss of roughly 18%. The jump to 3840x2160 at High is far more brutal, landing at 29.6 FPS — a 42% decline from the 1440p result and barely half of the 1080p figure.

This pattern repeats across every settings preset. At Low, the 1080p average of 81.8 FPS falls to 68.3 FPS at 1440p, then to 48.7 FPS at 4K. The Ultra preset tells the same story: 48.1 FPS at 1080p, 38.6 FPS at 1440p, and 27.5 FPS at 4K. The consistent scaling behavior — roughly 15-20% losses from 1080p to 1440p and another 30-40% from 1440p to 4K — is characteristic of a system where pixel throughput is the bottleneck.

The GTX 1070's 8 GB of GDDR5 memory on a 256-bit bus with 256.3 GB/s bandwidth is being pushed hard at higher resolutions. The data shows that even the most demanding 4K Ultra setting only achieves 27.5 FPS, which is below playable thresholds for most flight sim enthusiasts. The 4K Low figure of 48.7 FPS is more usable, but it requires sacrificing nearly all visual fidelity. The conclusion from the scaling data is unambiguous: this CPU has ample headroom, but the GPU runs out of steam well before 4K becomes viable at higher presets.

FAQ

Q: Is this combo capable of smooth 4K gameplay in Microsoft Flight Simulator?

A: Only at Low settings, where it averages 48.7 FPS. At Medium it drops to 35.3 FPS, High gives 29.6 FPS, and Ultra falls to 27.5 FPS. None of the higher presets reach the 60 FPS mark, and even Low is below that threshold.

Q: How does the GTX 1070 compare to its nearest rivals in raw GPU benchmarks?

A: The GTX 1070 has an average benchmark score of 12331, sitting 0.7% above the NVIDIA Quadro K4200 (12241), 1.3% below the GTX 880M (12490), and 1.4% below the GTX 1650 SUPER (12504). It ranks in the 51st percentile among all GPUs.

Q: What is the CPU's multi-threaded performance relative to its closest competitors?

A: The Ryzen 9 9900X scores 54450 on average, which is 0.4% below the Ryzen 9 9900X3D (54681), 0.7% above the Intel Core i7-14700F (54097), 1.5% below the Core Ultra 5 245K (55304), and 1.8% below the Core Ultra 5 245KF (55421). It ranks in the 94th percentile among all CPUs.

Q: Does the resolution scaling suggest a CPU or GPU bottleneck?

A: The data strongly indicates a GPU bottleneck. Frame rates drop by 30-40% when moving from 1440p to 4K at every settings preset, while the CPU's 12 cores and 24 threads remain largely underutilized in this workload. The GTX 1070's 6.463 TFLOPS FP32 throughput is the limiting factor.

Q: What is the best settings preset for 1440p gaming?

A: Medium at 50.8 FPS offers the best balance, as High drops to 41.6 FPS and Ultra to 38.6 FPS. Low reaches 68.3 FPS but sacrifices significant visual detail. Medium keeps the experience fluid while retaining acceptable image quality.

Q: How does this combo rank against all other tested combinations?

A: It ranks 1505 out of 1795 tested combos for Microsoft Flight Simulator, placing it in the bottom 16% of all pairings. This reflects the age and performance tier of the GTX 1070 relative to modern CPUs.

Settings Recommendations

For a smooth experience at 1920x1080, the Low preset delivers 81.8 FPS, which is well above the 60 FPS target. Medium at 62.4 FPS also clears that bar and provides noticeably better visuals, making it the recommended choice for most users at this resolution. High at 50.9 FPS is borderline, while Ultra at 48.1 FPS dips below comfort for fast-moving flight scenes.

At 2560x1440, the situation tightens. Medium at 50.8 FPS is the only preset that stays above the 50 FPS mark, making it the pragmatic pick. Low at 68.3 FPS is viable for those prioritizing frame rate, but the visual trade-off is steep. High at 41.6 FPS and Ultra at 38.6 FPS are playable but will feel less responsive, particularly during landing approaches or low-altitude maneuvers where scenery loads rapidly.

For 3840x2160, the data offers few good options. Low at 48.7 FPS is the only preset that approaches playability, but even it falls short of 60 FPS. Medium at 35.3 FPS, High at 29.6 FPS, and Ultra at 27.5 FPS are all below 36 FPS, which most simmers would find stuttery. If 4K is a requirement, the GTX 1070 simply lacks the pixel throughput to handle this simulator at higher quality levels. The pragmatic advice is to run 1080p Medium for the best overall experience, or 1440p Medium if a 60 FPS cap is not essential.

How This Combo Ranks

The combination of the Ryzen 9 9900X and GTX 1070 sits at rank 1505 out of 1795 tested combos for Microsoft Flight Simulator. That places it in the bottom 16% of all pairings, which is a poor result for a system built around a top-tier CPU. The CPU itself ranks in the 94th percentile among all processors, while the GPU sits at the 51st percentile — a massive imbalance that drags the overall combo ranking down.

This rank reflects the reality that Microsoft Flight Simulator is heavily GPU-bound at the resolutions and settings measured. The Ryzen 9 9900X's 12 cores and 24 threads are far more than this game needs at 1080p or 1440p, but the GTX 1070's Pascal architecture from 2016 cannot keep pace with the simulator's demands. The gap between the CPU's capability and the GPU's delivery is the defining characteristic of this pairing. For context, the GTX 1070's average benchmark score of 12331 is only 0.7% above a Quadro K4200, a professional card from a different era, and 1.7% below a Tesla K20Xm. The CPU, meanwhile, trades blows with the Ryzen 9 9900X3D and Core Ultra 5 245K, both of which are modern high-end parts.

The 1505th rank out of 1795 is a clear signal that this GPU is the wrong match for this CPU in this specific workload. A user with this processor would see dramatically better results with a more modern graphics card, as the CPU's headroom is largely wasted in this configuration.

CPU Role

The Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge), built on TSMC's 4 nm process. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a 64 MB shared L3 cache and 1 MB L2 per core. Its multi-threaded muscle is evident in Cinebench R23, where it scores 46438, and in PassMark's multithread test at 54643. Single-thread performance is equally strong: 6555 in Cinebench R23 single-core and 4672 in PassMark single-thread.

In Microsoft Flight Simulator, the game's engine is known to scale with CPU performance for physics, weather, and AI traffic calculations. The 9900X's high single-thread score of 1286 in 3DMark and 3341 in Geekbench single-core suggests it handles these tasks with ease. The measured frame rates, however, do not reflect this CPU strength — they are consistently limited by the GPU at every resolution and preset.

The data shows that the CPU is never the bottleneck in this pairing. At 1080p Low, the 81.8 FPS average is still far below what the 9900X could theoretically push if paired with a faster GPU. The 3DMark 16-thread score of 12552 and max-thread score of 13929 indicate substantial parallel capability, but Microsoft Flight Simulator's rendering pipeline is not leveraging it due to the GPU ceiling. The CPU's 89.6 GB/s memory bandwidth and dual-channel DDR5 support are more than adequate for this game's data streaming needs.

Measured FPS Breakdown

1920x1080:

• Low: 81.8 FPS
• Medium: 62.4 FPS
• High: 50.9 FPS
• Ultra: 48.1 FPS

The spread from Low to Ultra is 33.7 FPS, with the largest single drop occurring between Medium and High (11.5 FPS). Low is the only preset that clears 80 FPS; Medium is the only other one above 60 FPS.

2560x1440:

• Low: 68.3 FPS
• Medium: 50.8 FPS
• High: 41.6 FPS
• Ultra: 38.6 FPS

Low remains playable at 68.3 FPS, but Medium drops below 60 FPS. The gap between Low and Medium is 17.5 FPS, while High to Ultra is only 3.0 FPS, suggesting diminishing returns at the top end.

3840x2160:

• Low: 48.7 FPS
• Medium: 35.3 FPS
• High: 29.6 FPS
• Ultra: 27.5 FPS

No preset reaches 50 FPS. Low is 13.4 FPS ahead of Medium, and Ultra is only 2.1 FPS behind High. The 4K results are uniformly below the thresholds for smooth flight simulation, confirming the GPU as the hard limit.

Across all resolutions, the pattern is consistent: Low offers the highest headroom, Medium is the sweet spot for 1080p, and nothing above Low is advisable at 4K. The measured data provides no minimum or maximum FPS values, so average figures are the sole basis for these recommendations. The GTX 1070's 8 GB VRAM and 256.3 GB/s bandwidth are sufficient for 1080p but struggle with the texture and geometry loads at higher resolutions in Microsoft Flight Simulator.
