Microsoft Flight Simulator

The AMD Ryzen 9 7900X paired with the AMD Radeon RX 7700 delivers a playable but not exceptional experience in Microsoft Flight Simulator, with the data showing a clear pattern: the GPU becomes the dominant limiting factor as resolution climbs, while the CPU’s strong multi-threaded and single-threaded scores keep frame rates respectable at lower settings. The combo ranks 1324 out of 2996 tested combinations, placing it in the middle of the pack, and the measured FPS rows confirm that users must make deliberate choices about resolution and preset to hit their target smoothness.

Resolution Scaling

The measured FPS data for this combo shows a steep and predictable drop as resolution increases, which points directly at the GPU as the primary constraint in Microsoft Flight Simulator. Starting at 1920x1080, the average FPS across settings ranges from 126 at Low to 70 at Ultra, a spread of 56 FPS. Moving to 2560x1440, the same settings yield 102 at Low and 57 at Ultra, while at 3840x2160, the numbers fall to 75 at Low and 42 at Ultra. The scaling from 1080p to 1440p is roughly a 19% reduction at Low (126 to 102) and a 22% reduction at Ultra (70 to 57), but the jump from 1440p to 4K is more punishing: Low drops from 102 to 75 (–26%), and Ultra drops from 57 to 42 (–26%). This consistent percentage loss across settings indicates that the RX 7700’s rendering throughput, not the CPU, is what limits frame rates as pixel count grows.

The 4K results are particularly telling. At 3840x2160, even the Low preset only manages 75 FPS, which is below the 1080p Ultra figure of 70 FPS—but the Low preset at 4K still requires far more pixel fill than Ultra at 1080p, so the fact that it only gains 5 FPS over that lower-resolution Ultra setting shows how heavily the GPU is taxed. The medium preset at 4K produces 59 FPS with a minimum of 50 and a maximum of 67, indicating that the frame delivery is somewhat consistent but still under the 60 FPS threshold for most users. At 1080p, the Medium preset hits 98 FPS on average with a minimum of 84 and a maximum of 113, which is a much smoother experience.

The data suggests that for this game and this combo, the bottleneck shifts almost entirely to the GPU at 1440p and above. The Ryzen 9 7900X, with its 12 cores and 24 threads, has a Cinebench R23 multi-core score of 29300 and a single-core score of 2016.5, placing it in the 91st percentile of all CPUs. Those numbers indicate that the processor is not the constraint here; rather, the RX 7700’s 16 GB of GDDR6 memory and 624.1 GB/s bandwidth are being saturated by the simulator’s heavy draw calls and terrain rendering. The fact that Low settings at 4K (75 FPS) only slightly exceed High settings at 1080p (74 FPS) reinforces this: the GPU is working near its limit regardless of resolution, and the CPU has headroom that goes unused.

GPU Role

The AMD Radeon RX 7700’s specifications directly explain the FPS behavior seen in the measured rows. The GPU has a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz, with 2560 shading units, 160 TMUs, and 96 ROPs. The memory subsystem is a 256-bit bus with 16 GB of GDDR6 running at 2438 MHz (19.5 Gbps effective), yielding a bandwidth of 624.1 GB/s. These figures place the RX 7700 in the 58th percentile of all GPUs, with an average benchmark score of 15852. Its nearest rivals in the database are the AMD Radeon R9 370X (avg score 15862, delta 0.1%), the AMD Radeon RX 9060 (avg score 16014, delta –1%), the AMD Radeon Pro W5500 (avg score 15679, delta 1.1%), and the NVIDIA GeForce RTX 3060 Ti (avg score 16129, delta –1.7%). The delta percentages are tight, meaning the RX 7700 sits in a crowded performance band.

In Microsoft Flight Simulator, the GPU’s role is pronounced because the game renders vast landscapes, detailed aircraft models, and dynamic weather. The measured FPS at 1080p Low (126 FPS) shows that the GPU can push high frame rates when the visual load is light, but the drop to 70 FPS at Ultra reveals that the extra shading and texture work quickly consume the available bandwidth and pixel throughput. The 16 GB VRAM is ample for this title, as the game does not appear to run out of memory at any resolution in the data—the FPS drops are consistent with compute and fill-rate limits rather than memory capacity issues. The 624.1 GB/s bandwidth is moderate by current standards, and the measured scaling suggests that the GPU’s 25.18 TFLOPS FP32 performance is the ceiling for this combo.

The fact that the GPU’s nearest rival is the RTX 3060 Ti, which has a slightly higher average benchmark score (16129 vs 15852), is relevant because that card is often used in similar builds. In this game, the RX 7700’s measured FPS at 1080p Ultra (70 FPS) and 1440p Ultra (57 FPS) are plausible for a GPU in this class, and the data does not suggest any unusual driver or architecture advantage for Flight Simulator. The RDNA 3.0 architecture, built on a 5 nm process with 28,100 million transistors, delivers a texture rate of 393.4 GTexel/s and a pixel rate of 236.1 GPixel/s, which are the raw numbers that determine how fast the scene can be filled. At 4K Ultra, the 42 FPS average is consistent with those throughput figures, and the Low preset at 4K (75 FPS) shows that reducing the render load allows the GPU to nearly double its output.

FAQ

Q: What is the best resolution for this combo in Microsoft Flight Simulator?

A: The data shows that 1920x1080 offers the highest frame rates across all settings, with Low hitting 126 FPS, Medium 98 FPS, High 74 FPS, and Ultra 70 FPS. At 2560x1440, the averages drop to 102, 79, 60, and 57 FPS respectively, while 3840x2160 falls to 75, 59, 44, and 42 FPS. For a smooth experience, 1080p is the most consistent choice.

Q: How does the RX 7700 compare to its nearest GPU rivals in terms of overall benchmark scores?

A: The RX 7700 has an average benchmark score of 15852, which is 0.1% below the AMD Radeon R9 370X (15862), 1% below the AMD Radeon RX 9060 (16014), 1.1% above the AMD Radeon Pro W5500 (15679), and 1.7% below the NVIDIA GeForce RTX 3060 Ti (16129). These deltas are small, indicating near-parity performance.

Q: Is the Ryzen 9 7900X a bottleneck at 1080p?

A: No, the CPU’s benchmark scores are strong—Cinebench R23 multi-core is 29300, single-core is 2016.5, and it sits in the 91st percentile of all CPUs. The FPS at 1080p Low (126) and Medium (98) suggests the GPU is still the limiting factor, as the CPU can deliver far more frames than the RX 7700 can render.

Q: What is the minimum FPS recorded for any setting?

A: The only measured minimum FPS values are in the Medium preset: 84 FPS at 1920x1080, 67 FPS at 2560x1440, and 50 FPS at 3840x2160. Other presets list no minimum, so the data cannot confirm dips for Low, High, or Ultra.

Q: How does this combo rank among all tested combinations?

A: The combo ranks 1324 out of 2996 total combos, which places it just below the median. This indicates that while the system is capable, it is not among the top performers for this game.

Q: Does the 16 GB VRAM ever become a limiting factor?

A: The data does not indicate VRAM exhaustion. The FPS drops from 1080p to 4K are proportional to resolution scaling, which points to compute and bandwidth limits rather than memory capacity. The 16 GB and 624.1 GB/s bandwidth are sufficient for the measured settings.

Measured FPS Breakdown

The measured FPS table provides a complete picture of this combo’s performance across three resolutions and four settings presets. At 1920x1080, the average FPS ranges from 126 at Low to 70 at Ultra. The Medium preset is the only one with a reported range: 84 minimum, 98 average, and 113 maximum. High sits at 74 FPS on average, and Ultra at 70. These numbers show that from Low to Ultra, the performance drop is 56 FPS, or about 44%, which is substantial but leaves the system above 60 FPS for all presets except Ultra, which is just barely above it.

At 2560x1440, the averages are 102 at Low, 79 at Medium, 60 at High, and 57 at Ultra. The Medium preset again has a range: 67 minimum, 79 average, and 91 maximum. The drop from Low to Ultra is 45 FPS, or 44%, mirroring the 1080p scaling. The key difference is that High and Ultra both fall below 60 FPS, which may cause noticeable stutter in a flight simulator where smooth panning is important. The 1440p Medium preset, with a 79 FPS average and a 67 FPS minimum, is the best balance for this resolution.

At 3840x2160, the averages are 75 at Low, 59 at Medium, 44 at High, and 42 at Ultra. The Medium preset’s range is 50 minimum, 59 average, and 67 maximum. The scaling from Low to Ultra is 33 FPS, or 44%, again consistent. No preset at 4K reaches 60 FPS on average, and the High and Ultra presets dip below 45 FPS, which is likely to feel sluggish. The Low preset at 75 FPS is the only 4K option that approaches a playable frame rate, though it still falls short of the 1440p Medium experience.

The pattern across all resolutions is that the preset choice affects FPS by roughly 44% from Low to Ultra, regardless of resolution. This consistency suggests that the GPU’s workload scaling is linear with respect to visual complexity, and that the CPU is never the limiting factor. The Medium preset consistently offers the best minimum FPS, which is important for avoiding hitches in a simulator where sudden frame drops can ruin the experience.

How This Combo Ranks

The combo’s rank of 1324 out of 2996 tested combinations places it in the 44th percentile of all systems tested for Microsoft Flight Simulator. This is a mid-pack result, which aligns with the GPU’s 58th percentile ranking among all GPUs and the CPU’s 91st percentile ranking among all CPUs. The gap between the CPU’s high percentile and the combo’s lower rank underscores that the GPU is holding back the system’s overall performance in this game.

Looking at the CPU’s nearest rivals, the Ryzen 9 7900X has an average benchmark score of 53288, which is 0.2% above the AMD EPYC 7313P (53206), 0.3% below the Intel Xeon Phi 7290 (53469), 0.6% above the Intel Xeon 634 (52974), and 0.6% below the Intel Core i7-14700F (53620). These rivals are all server or high-end desktop parts, and the 7900X holds its own within this group. However, the GPU’s nearest rivals are all much older or lower-tier cards, which explains why the combo lands in the middle of the pack: a strong CPU paired with a mid-range GPU produces a system that is CPU-overqualified for the workload.

The ranking data suggests that to improve performance in Flight Simulator, users would need to upgrade the GPU rather than the CPU. The RX 7700’s average benchmark score of 15852 is close to the RTX 3060 Ti’s 16129, and both are far below what top-tier GPUs would offer, but the fact that the CPU has headroom (as shown by its 91st percentile) means that a faster GPU would likely yield significant FPS gains. The combo’s rank of 1324 out of 2996 is not a failure, but it is clear that this is a balanced mid-range system rather than a high-end Flight Simulator rig.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the user’s target resolution and acceptable frame rate. For 1920x1080, the data shows that High (74 FPS) and Ultra (70 FPS) are both playable, but Medium (98 FPS) provides a substantial margin above the 60 FPS threshold. The Medium preset’s minimum of 84 FPS is the highest minimum recorded for any setting in the table, which means it offers the most consistent frame delivery. For users who want the best visuals without sacrificing smoothness, High is the recommended preset at 1080p, as it stays above 70 FPS and only costs 4 FPS compared to Ultra.

At 2560x1440, the choices are more constrained. High (60 FPS) and Ultra (57 FPS) both hover at or below the 60 FPS line, which can lead to occasional dips during heavy scenery loads. Medium (79 FPS with a 67 FPS minimum) is the clear recommendation for 1440p, as it provides a comfortable buffer above 60 FPS and the minimum FPS never drops below 67. Low (102 FPS) is an option for competitive or fast-paced flying, but the visual compromise is significant. The data indicates that Medium is the sweet spot at this resolution, offering nearly 80 FPS on average.

At 3840x2160, no preset achieves a 60 FPS average. Medium (59 FPS) is the closest, with a minimum of 50 FPS, which may be acceptable for slower, more scenic flights. Low (75 FPS) is the only 4K preset that delivers a clearly smooth experience, but it requires a major reduction in visual fidelity. High (44 FPS) and Ultra (42 FPS) are both below 45 FPS, which is likely to feel stuttery in a simulator that relies on continuous camera movement. For 4K users, the recommendation is to use Low if frame rate is the priority, or Medium if visual quality is more important and the user can tolerate occasional dips below 60 FPS.

Overall, the data suggests that this combo is best utilized at 1920x1080 with High or Medium settings, or at 2560x1440 with Medium settings. The 4K experience is possible but requires accepting lower frame rates or reduced visual quality. The RX 7700’s 16 GB VRAM and 624.1 GB/s bandwidth are sufficient for all settings, but the GPU’s raw compute throughput of 25.18 TFLOPS is the ceiling. Users who want to fly at 4K Ultra would need to look at a higher-tier GPU, as the current combo’s measured 42 FPS at 4K Ultra is below the threshold for smooth simulation.
