Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the benchmark suite, and the pairing of the AMD Ryzen 7 5700G with the Intel Arc B390 produces results that are heavily constrained by the graphics subsystem. The data indicates a configuration that is capable of running the simulator, but only at lower resolutions and settings presets. The measured frame rates across all resolutions consistently fall below the 60 FPS threshold, placing this combo near the bottom of the tested rankings for this specific game.

Resolution Scaling

The measured FPS data reveals a clear and steep decline in performance as resolution increases, a pattern that strongly indicts the graphics processor as the primary limiting factor. At 1920x1080 with Low settings, the combo achieves an average of 56 FPS. Moving to 2560x1440 with the same Low preset drops the average to 45 FPS, a reduction of 11 FPS or approximately 19.6% from the 1080p result. Pushing further to 3840x2160 at Low settings yields an average of 33 FPS, which is a 23 FPS drop from the 1080p baseline, representing a 41.1% decrease in performance.

This scaling behavior is consistent across all settings presets. For instance, at Medium settings, the average FPS goes from 43 at 1080p, to 35 at 1440p, and finally to 26 at 4K. The pattern confirms that the rendering load is overwhelming the GPU at higher pixel counts. The data shows that the transition from 1080p to 1440p is less punishing than the jump from 1440p to 4K, indicating that the GPU's memory bandwidth and shading capacity are being saturated as the pixel count increases exponentially. The frame rate at 4K Ultra, at 19 FPS, is identical to the 4K High result, suggesting that the GPU has hit a hard computational ceiling where further increases in graphical fidelity do not cost additional performance because the hardware is already fully utilized. The limiting component is unequivocally the Intel Arc B390 integrated graphics, as the frame rate is directly tied to the resolution-driven workload.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, and its performance characteristics are the dominant factor in this combo's results. The GPU operates with a base clock of 300 MHz and a boost clock of 2500 MHz, and it relies on System Shared memory for both capacity and bandwidth, meaning its performance is partly dependent on the host system's RAM. The benchmark data for this GPU is sparse, with a single 3DMark Steel Nomad DX12 score of 1482, which places it at the 9th percentile of all tested GPUs. Its nearest rivals, according to the data, include the NVIDIA GeForce GT 520MX and the GeForce GT 710, with deltaPct values of 1.3% and 2.7% respectively, indicating that the Arc B390 is in the same performance class as these older, low-end discrete parts.

Given this GPU's limited compute resources—1536 shading units, 48 TMUs, and 24 ROPs—the low frame rates in Microsoft Flight Simulator are expected. The game's rendering of vast landscapes and detailed cockpit geometry is a heavy load for an IGP. The fact that the 4K High and 4K Ultra presets both result in an average of 19 FPS suggests that the GPU is not being limited by specific settings but by its raw fillrate and shader throughput. The boost clock of 2500 MHz is relatively high for an integrated solution, but it cannot compensate for the lack of dedicated memory bandwidth. The "System Dependent" bandwidth and "System Shared" memory type are critical bottlenecks, as the GPU must compete with the CPU for memory access, which is particularly detrimental in a simulation that manages a large amount of game state data. The data shows that this GPU is not capable of delivering a smooth experience at any resolution above 1080p, and even at 1080p, it only manages a playable frame rate on the Lowest settings preset.

FAQ

Q: What is the highest average frame rate this combo achieves in Microsoft Flight Simulator?

A: The highest measured average frame rate is 56 FPS, which occurs at 1920x1080 resolution with the Low settings preset.

Q: How does this combo compare to its nearest GPU rivals in terms of raw performance?

A: The Intel Arc B390 has an average benchmark score of 1482, placing it 1.3% above the NVIDIA GeForce GT 520MX and 2.7% above the NVIDIA GeForce GT 625 OEM. This indicates it is marginally faster than these older entry-level GPUs.

Q: Does increasing the resolution have a larger impact on performance than increasing the settings preset?

A: Yes, the data shows resolution scaling has a more profound effect. For example, moving from 1080p Low (56 FPS) to 4K Low (33 FPS) results in a 23 FPS drop, whereas moving from 1080p Low (56 FPS) to 1080p Ultra (31 FPS) results in a 25 FPS drop. However, the resolution jump from 1440p to 4K is particularly steep, highlighting the GPU's memory bandwidth limits.

Q: What is the frame rate behavior at 2560x1440 with Medium settings?

A: At 2560x1440 with Medium settings, the combo produces an average of 35 FPS, with a minimum of 30 FPS and a maximum of 40 FPS. This shows a noticeable performance dip compared to the 43 FPS average at 1080p Medium.

Q: Is the CPU a limiting factor in this game with this configuration?

A: The data suggests the GPU is the primary bottleneck, as frame rates scale heavily with resolution. However, the CPU's performance is also modest. The Ryzen 7 5700G scores 12830.5 in Cinebench R23 multicore and 1494 in single-core, which is adequate but not exceptional, meaning it is unlikely to be the main cause of the low FPS, but it is not a high-end performer either.

Q: How does this combo rank overall compared to other tested configurations?

A: The combo ranks 2665th out of 2996 tested combos for this game, placing it in the bottom 11% of all configurations. This poor ranking is consistent with the low frame rates measured across all settings and resolutions.

Measured FPS Breakdown

The complete set of measured frame rates provides a detailed look at the combo's performance across the grid of resolutions and settings.

At 1920x1080, the combo shows its best results. The Low preset yields an average of 56 FPS, which is the only measurable result that approaches a playable level. The Medium preset averages 43 FPS with a range of 37 to 50 FPS. The High preset drops to an average of 33 FPS, and the Ultra preset falls further to an average of 31 FPS. The spread between Low and Ultra at this resolution is 25 FPS, showing that the game's graphical options have a significant impact on the GPU load.

At 2560x1440, performance degrades across the board. The Low preset averages 45 FPS, a solid drop from the 1080p result. The Medium preset averages 35 FPS with a range of 30 to 40 FPS. The High preset averages 26 FPS, and the Ultra preset averages 25 FPS. The difference between High and Ultra narrows to just 1 FPS, indicating that the GPU is becoming the limiting factor and cannot handle the increased detail.

At 3840x2160, the combo is clearly overmatched. The Low preset is the only one that breaks the 30 FPS barrier, averaging 33 FPS. The Medium preset averages 26 FPS with a range of 22 to 30 FPS. The High and Ultra presets both average 19 FPS, showing a hard performance ceiling. The data points to a system that can only deliver a semi-playable experience at 1080p on the lowest settings or at 4K on the lowest settings, but not at any higher graphical fidelity.

How This Combo Ranks

The combo's position in the database is a stark indicator of its performance class. With a rank of 2665 out of 2996 combos, it sits in the bottom 11.1% of all tested configurations for Microsoft Flight Simulator. This ranking is a direct consequence of the Intel Arc B390's limitations, as the GPU's 3DMark Steel Nomad score of 1482 places it in the 9th percentile of all GPUs. The data shows that this is not a viable configuration for high-fidelity flight simulation.

The GPU's nearest rivals, such as the NVIDIA GeForce GT 710, are known for being basic display adapters rather than gaming hardware, and the Arc B390's performance is in line with those parts. The CPU, while more capable, cannot compensate for the GPU's weakness in a graphically intensive title. The rank of 2665 indicates that the vast majority of other tested systems, even those with older CPUs, are able to achieve higher frame rates, likely due to having a more powerful discrete graphics card. This combo is effectively limited to the lowest tiers of performance, and users seeking a better experience would need to consider a fundamentally different GPU solution.

CPU Role

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture. Its benchmark scores indicate it is a mid-range performer. It achieves a Cinebench R23 multicore score of 12830.5 and a single-core score of 1494. In the broader CPU benchmark, it has an average score of 27051, which places it in the 79th percentile of all CPUs. Its nearest rivals include the Intel Core i9-9900K, which is 0.2% faster, and the AMD Ryzen AI 7 445, which is 0.4% slower.

In Microsoft Flight Simulator, the CPU's role is significant for handling the simulation's physics, flight models, and AI traffic. However, the measured FPS data shows that the GPU is the primary bottleneck. The frame rates are consistently low across all resolutions, and the steep scaling with resolution points to a GPU limitation. If the CPU were the bottleneck, we would expect to see more consistent frame rates across different resolutions. The Ryzen 7 5700G's boost clock of 4.60 GHz provides adequate single-thread performance, as evidenced by its 1494 Cinebench R23 score, which is sufficient to feed the GPU at these low performance levels. The CPU is not the limiting factor here; it is the Intel Arc B390 that holds the system back.

Settings Recommendations

Based on the measured data, the only way to achieve a remotely playable experience with this combo is to prioritize frame rate over visual fidelity. The single configuration that breaks the 50 FPS barrier is 1920x1080 with the Low preset, which yields an average of 56 FPS. This is the only setting that provides a frame rate suitable for a smooth simulation experience, as the next best result is 45 FPS at 1440p Low.

For users who can tolerate a lower frame rate, the 1920x1080 Medium preset offers an average of 43 FPS, which is a more visually detailed image but still below the ideal threshold. The data shows that any attempt to run the game at High or Ultra settings at any resolution results in average frame rates below 35 FPS, which will feel stuttery and unresponsive for a flight simulator that requires precise control. At 4K, the results are uniformly poor, with the best option being the Low preset at 33 FPS. The recommendation is clear: to get the most out of this hardware, run the game at 1080p with the Low preset. This is the only configuration that provides a playable frame rate, and sacrificing graphical details is necessary to achieve it.
