# Microsoft Flight Simulator — Intel Core Ultra 5 245 + Intel Arc B570

This pairing of Intel's Arrow Lake desktop CPU with the Arc B570 graphics card produces a system that sits near the bottom quartile of tested combos in Microsoft Flight Simulator, ranking 2988 out of 3714 configurations. The data reveals a GPU-bound experience at higher resolutions, with the CPU showing clear headroom at 1080p. The Arc B570's 10 GB of GDDR6 memory and 380.0 GB/s bandwidth shape the experience significantly, as do the Core Ultra 5 245's 14 cores and 3.50 GHz base clock. Benchmark results indicate this is a combination that can handle the sim at playable framerates on lower presets, but Ultra settings push it below 30 FPS at 4K.

Resolution Scaling

The measured FPS data shows a steep drop as resolution climbs, which is typical for a flight simulator that stresses both geometry and texture bandwidth. At Low settings, the average FPS falls from 86 at 1920x1080 to 69 at 2560x1440, a decline of 17 FPS, then to 51 at 3840x2160, another 18 FPS drop. This linear degradation pattern suggests the GPU is the primary limiter even at Low, since the CPU has ample headroom with its 5.10 GHz boost clock and 24 MB of shared L3 cache.

Medium settings tell a similar story: 67 FPS at 1080p, 54 at 1440p, and 40 at 4K. The scaling from 1080p to 1440p is a 13 FPS reduction, while 1440p to 4K costs 14 FPS. High settings show 50, 41, and 30 FPS respectively, with the 4K figure dipping below the 30 FPS threshold that many consider the minimum for a smooth experience. Ultra settings are even more punishing: 48 FPS at 1080p, 39 at 1440p, and 28 at 4K.

What the data implies is that the Arc B570's 160-bit memory bus and 380.0 GB/s bandwidth become increasingly strained as pixel count rises. The 10 GB VRAM capacity is sufficient for most presets, but the bandwidth constraint shows in the consistent 15-20% FPS loss per resolution step. Notably, the gap between Low and Ultra at 1080p is 38 FPS (86 vs 48), while at 4K it narrows to 23 FPS (51 vs 28), suggesting that at higher resolutions, the GPU's compute and memory throughput are so saturated that preset changes yield diminishing returns.

The 3 nm CPU node and 102.4 GB/s memory bandwidth of the Core Ultra 5 245 appear more than adequate for this workload, as evidenced by the fact that even at 1080p Low, the system reaches 86 FPS without obvious CPU bottlenecks. The scaling curve points to the Arc B570 as the limiting component across all resolutions, with the CPU contributing less to frame rate variance as resolution increases.

Settings Recommendations

For 1080p users, the data clearly supports Medium as the sweet spot. The 67 FPS average at Medium is 17 FPS higher than High's 50 FPS, while the visual quality difference between Medium and High is typically modest in flight simulators. The measured minimum of 57 FPS at Medium 1080p indicates good frame pacing, whereas High's average of 50 FPS leaves less margin for complex scenery. Ultra at 1080p delivers 48 FPS, which is only marginally below High but with a larger visual fidelity cost — the 2 FPS difference between High and Ultra does not justify the additional GPU load.

At 1440p, Medium again emerges as the recommended preset. The 54 FPS average is playable, and the minimum of 46 FPS stays above the 40 FPS threshold where stutter becomes noticeable. High at 1440p drops to 41 FPS, which is borderline for a simulator where smooth panning is essential. Low at 1440p offers 69 FPS, but the visual quality loss in a game that relies heavily on terrain detail and cockpit readability makes Medium the better trade-off.

For 4K, the data suggests Low is the only viable preset for consistent playability, with 51 FPS. Medium at 4K falls to 40 FPS with a minimum of 34 FPS, which will produce noticeable judder during cloud-heavy sections or busy airport approaches. High and Ultra at 4K — 30 FPS and 28 FPS respectively — are below playable thresholds for most users. The 4K Medium minimum of 34 FPS is particularly telling; it shows the GPU struggling to maintain frame rate during complex scenes.

Ultra settings are only recommended for 1080p users who prioritize visual fidelity over frame rate, since the 48 FPS average is still technically playable. However, given that Ultra at 1080p is only 2 FPS slower than High, users who can tolerate 48 FPS might as well enable Ultra for the maximum visual experience the Arc B570 can deliver at that resolution.

How This Combo Ranks

This configuration ranks 2988 out of 3714 tested combos in Microsoft Flight Simulator, placing it in the bottom 20% of all systems. The percentile position is consistent with the measured FPS data, which shows the Arc B570 performing below the median GPU in this title. The combo's rank reflects the GPU's 65th percentile standing among all GPUs in the benchmark database, combined with the CPU's 90th percentile position — a mismatch that suggests the GPU is holding back the system.

The Core Ultra 5 245's nearest CPU rivals include the AMD Ryzen 7 PRO 5755G and AMD Ryzen 9 7900, both with average scores within 0.5% of the Intel chip. This indicates the CPU is well within the performance range of its peers, and any ranking shortfall is unlikely to be CPU-related. The Arc B570's nearest GPU rivals include the NVIDIA GeForce RTX 3070 Mobile and Intel Arc A750, with delta percentages of 0.1% and -0.1% respectively, showing the B570 is closely matched with those parts.

The 3714 total combos in this game's database include many high-end pairings, so a rank of 2988 is not surprising for a mid-range GPU with a strong CPU. The data implies that users with this combo will see frame rates roughly in line with what the Arc B570's PassMark G3D score of 14195 would predict — solidly mid-pack but not competitive with top-tier cards. In a title like Microsoft Flight Simulator, which is known for demanding both CPU and GPU, this rank reflects the GPU's limitations more than the CPU's capabilities.

Measured FPS Breakdown

At 1920x1080, the measured averages span from 86 FPS at Low to 48 FPS at Ultra. Medium produces 67 FPS with a minimum of 57 and maximum of 77, while High sits at 50 FPS. The spread between Low and Ultra is 38 FPS, indicating that the GPU's 11.52 TFLOPS of FP32 compute is the limiting factor as settings increase.

At 2560x1440, Low delivers 69 FPS, Medium 54 FPS (minimum 46, maximum 62), High 41 FPS, and Ultra 39 FPS. The gap between High and Ultra narrows to just 2 FPS at this resolution, suggesting that the Ultra preset's additional effects are largely GPU-bound and provide little benefit. The 1440p numbers show a 30 FPS difference between Low and Ultra.

At 3840x2160, the averages are 51 FPS at Low, 40 FPS at Medium (minimum 34, maximum 46), 30 FPS at High, and 28 FPS at Ultra. The 4K data reveals a compression of the settings range, with only 23 FPS separating Low from Ultra. This compression is a classic sign of memory bandwidth saturation — the 380.0 GB/s bus simply cannot feed the GPU's shader units fast enough to differentiate presets.

The Medium preset is the only setting where minimum and maximum FPS values were recorded across all resolutions, providing insight into frame consistency. At 1080p Medium, the 20 FPS spread between minimum and maximum indicates decent consistency. At 1440p, the spread widens to 16 FPS, and at 4K it reaches 12 FPS. The narrowing spread at higher resolutions suggests the GPU is hitting a hard performance ceiling, with less headroom for frame rate variation.

GPU Role

The Intel Arc B570's 10 GB of GDDR6 memory on a 160-bit bus provides 380.0 GB/s of bandwidth, which the measured data shows is the primary constraint in Microsoft Flight Simulator. The 2500 MHz base and boost clocks (identical, indicating the card runs at a fixed frequency) deliver 11.52 TFLOPS of FP32 performance and 360.0 GTexel/s of texture fill rate. These specs place the B570 in the 65th percentile of all GPUs in the benchmark database.

The GPU's 18 ray tracing cores and 2304 shading units are relevant to Flight Simulator's use of ray-traced shadows and reflections, though the game's primary load is traditional rasterization. The 80 ROPs provide a 200.0 GPixel/s pixel rate, which is adequate for 1080p but struggles at 4K where the 30 FPS High preset average reflects the pixel throughput limit. The 19 Gbps effective memory speed is fast, but the 160-bit bus width limits total bandwidth to 380.0 GB/s — a figure that the 4K results suggest is insufficient for Ultra settings.

The GPU's nearest rivals include the Intel Arc A750 (deltaPct -0.1%) and NVIDIA GeForce RTX 3070 Mobile (deltaPct 0.1%), indicating the B570 sits at a performance level comparable to those cards in synthetic benchmarks. However, in this specific game, the B570's 4K performance is notably weak, with the 28 FPS Ultra average falling below the 30 FPS playability threshold. The 10 GB VRAM is not the issue — Flight Simulator's textures typically fit within 8 GB at 4K — but the bandwidth ceiling is. The PassMark G3D score of 14195 and GPU compute score of 7281 both point to a mid-range part that is well-matched to 1080p and acceptable at 1440p, but not designed for 4K gaming.

FAQ

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

A: The data shows 1920x1080 as the optimal resolution, where Low delivers 86 FPS and Medium 67 FPS, both well above playable thresholds. At 2560x1440, only Low and Medium exceed 50 FPS, while 3840x2160 dips below 40 FPS on all presets except Low.

Q: Can this system run Ultra settings?

A: Yes, but only at 1080p where it achieves 48 FPS. At 1440p Ultra drops to 39 FPS, and at 4K Ultra falls to 28 FPS — below the 30 FPS minimum for smooth play. The Ultra preset's 2 FPS advantage over High at 1440p and 4K suggests the GPU is saturated.

Q: How does the Arc B570 compare to its nearest GPU rivals in this game?

A: The B570's nearest rivals are the Intel Arc A750 (deltaPct -0.1%) and NVIDIA GeForce RTX 3070 Mobile (deltaPct 0.1%), meaning performance is statistically identical in synthetic benchmarks. However, the measured FPS data in Flight Simulator shows the B570 hitting 30 FPS at 4K High, which is marginal.

Q: Is the CPU or GPU the bottleneck in this system?

A: The data indicates GPU bottlenecking at all resolutions. The Core Ultra 5 245 ranks in the 90th percentile of CPUs, while the Arc B570 ranks in the 65th percentile of GPUs. The FPS scaling from 1080p to 4K shows consistent drops that track GPU load, not CPU capability.

Q: What FPS can users expect at 1440p Medium?

A: The measured average is 54 FPS, with a minimum of 46 FPS and maximum of 62 FPS. This is the most balanced preset at this resolution, offering playable performance with reasonable visual quality.

Q: Does the 10 GB VRAM cause any issues?

A: No — the data does not indicate VRAM capacity as a limiting factor. The 380.0 GB/s memory bandwidth is more likely the constraint, as the FPS drops between presets and resolutions suggest throughput limits rather than capacity overflow.

CPU Role

The Intel Core Ultra 5 245 brings 14 cores and 14 threads across its Arrow Lake architecture, with a base clock of 3.50 GHz and boost clock of 5.10 GHz. The 24 MB of shared L3 cache and 3 MB L2 cache per core provide substantial on-chip storage for Flight Simulator's streaming terrain data. The CPU's 90th percentile ranking among all processors, with an average benchmark score of 48995, places it well above the GPU's 65th percentile, confirming the CPU is not the performance limiter in this pairing.

The CPU's nearest rivals include the AMD Ryzen 7 PRO 5755G (deltaPct -0.4%) and AMD Ryzen 9 7900 (deltaPct -0.5%), both of which score within half a percentage point of the Intel chip. The Intel Core i5-14600K is also close (deltaPct 0.8%), indicating this CPU's performance class is competitive with mid-range and upper-mid-range desktop parts. In Cinebench R23, the CPU scores 32924 multicore and 4648 singlecore, which are strong numbers for a 65 W TDP part.

Flight Simulator's CPU load is primarily single-threaded for the main simulation loop, with some multi-threaded use for scenery loading and AI traffic. The Core Ultra 5 245's 5.10 GHz boost clock and strong single-core performance (4648 in Cinebench R23) are well-suited to this workload. The 14 threads are sufficient for the game's secondary threads, and the 102.4 GB/s dual-channel DDR5 memory bandwidth provides adequate data throughput for streaming world geometry.

The 3 nm process node and 17,800 million transistors on a 243 mm² die explain the CPU's efficiency, with a 65 W TDP that keeps thermals manageable. The CPU's 90th percentile rank means it outperforms 90% of all CPUs in the benchmark database, yet the system's overall combo rank of 2988 out of 3714 shows that the GPU drags the experience down. In this title, the CPU's role is to feed the GPU without bottlenecking, and the data confirms it does so — the FPS scaling patterns are entirely consistent with GPU limitations, not CPU constraints.
