# Microsoft Flight Simulator: Intel Core Ultra 5 245 + NVIDIA GeForce RTX 5090 D

This combo ranks 11th out of 2,996 tested configurations in Microsoft Flight Simulator, placing it in the top 0.4% of all tested hardware pairings. The pairing of Intel's Core Ultra 5 245 with NVIDIA's RTX 5090 D produces a system that handles this flight simulator with substantial headroom across all tested resolutions and presets, though the data reveals interesting bottlenecks that shift depending on where you look.

How This Combo Ranks

The 11th-place ranking out of 2,996 combos is notable for a processor that sits in the 90th percentile among all CPUs. The Intel Core Ultra 5 245's average benchmark score of 48,995 places it within a hair of the AMD Ryzen 7 PRO 5755G (49,196, only 0.4% faster) and the AMD Ryzen 9 7900 (49,228, 0.5% faster). It edges out the Intel Xeon Gold 5318H by 0.6% and the Intel Core i5-14600K by 0.8%. This CPU is clearly competitive with mid-range and even some high-end options from rival lineups, yet it's paired with the RTX 5090 D, which sits in the 92nd percentile among all GPUs.

The GPU itself has an average benchmark score of 77,712, with nearest rivals including the AMD Radeon RX 6650M XT (76,904, 1.1% slower) and the AMD Radeon RX 6850M XT (78,940, 1.6% faster). What's striking is that the RTX 5090 D's nearest rivals are all mobile or workstation parts, not desktop gaming GPUs — the data suggests this card occupies an unusual performance tier. Despite this, the combo's rank of 11 suggests that in Microsoft Flight Simulator specifically, the CPU is not holding the system back from near-top-tier placement.

The gap between this combo and the very top of the ranking likely stems from the CPU's position relative to faster processors. With 14 cores and 14 threads, the Core Ultra 5 245 is no slouch, but its single-thread performance — a Cinebench R23 single-core score of 4,648 — may be the limiting factor in a simulator known for heavy single-threaded workloads. The data implies that while this combo is exceptional overall, there's room above it for configurations with stronger single-core CPUs.

GPU Role

The RTX 5090 D brings 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. That memory configuration is overkill for Microsoft Flight Simulator at any resolution tested here, but it explains why the GPU never appears to be the primary constraint in the measured results. The card's 21,760 shading units and 170 RT cores provide massive raw compute, with FP32 performance rated at 104.8 TFLOPS.

Clock speeds show a base of 2017 MHz and a boost of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). These clocks are moderate for a flagship GPU, but the sheer scale of the chip — 92,200 million transistors on a 750 mm² die — compensates. At 4K Ultra, the combo still manages 84 FPS, which is exceptionally smooth for a flight simulator. The GPU's pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s suggest it can feed even the most demanding scenery detail without breaking a sweat.

The data shows something interesting: at 1080p Low, the system hits 242 FPS, but at 4K Ultra it drops to 84 FPS. That's a 65% reduction in frame rate as resolution and settings scale up, which indicates the GPU is doing meaningful work at higher settings even if it's not fully saturated. The RTX 5090 D's 32 GB VRAM means texture streaming and large scenery areas present no memory pressure — the card never approaches capacity in this game, freeing it to focus purely on rendering.

FAQ

Q: Is this combo overkill for 1080p gaming in Microsoft Flight Simulator?

A: The data shows 242 FPS at 1080p Low and 149 FPS at 1080p High, which far exceeds the refresh rates of most monitors. The system is clearly GPU-bound at this resolution, and the CPU's single-thread performance (Cinebench R23 single-core score of 4,648) becomes the more relevant metric for maintaining high frame rates.

Q: How does the RTX 5090 D compare to its nearest GPU rivals in raw compute?

A: The RTX 5090 D's average benchmark score of 77,712 puts it 1.1% ahead of the AMD Radeon RX 6650M XT (76,904) and 1.6% behind the AMD Radeon RX 6850M XT (78,940), but 2.1% ahead of the NVIDIA Tesla P100 PCIe 12 GB (79,396 is the rival score, so the RTX is actually behind — the deltaPct of -2.1 means the Tesla is 2.1% faster).

Q: What resolution and settings combo delivers the highest frame rate in this game?

A: The fastest measured result is 242 FPS at 1080p Low. The 1440p Low setting yields 205 FPS, and 4K Low produces 151 FPS. For higher visual quality, 1080p Ultra runs at 142 FPS, while 4K Ultra drops to 84 FPS.

Q: Does the CPU's 14-core, 14-thread configuration help in this game?

A: Microsoft Flight Simulator is known for favoring single-thread performance. The Core Ultra 5 245's Cinebench R23 single-core score of 4,648 and multi-core score of 32,924 indicate strong performance in both areas, but the lack of simultaneous multithreading (14 threads from 14 cores) suggests the CPU relies on raw core count rather than thread duplication.

Q: How much VRAM does this game need, and does the RTX 5090 D's 32 GB matter?

A: The measured results show no signs of VRAM limitation at any resolution or setting, including 4K Ultra. The 32 GB GDDR7 allocation is far beyond what Microsoft Flight Simulator requires, meaning the card's 1.79 TB/s bandwidth is used for rendering throughput rather than fighting memory constraints.

Q: Is the Core Ultra 5 245 a bottleneck for the RTX 5090 D in this game?

A: The combo's 11th-place rank out of 2,996 suggests the CPU is not a severe bottleneck, but the FPS scaling from 1080p to 4K reveals where the CPU's influence ends. At 1080p Low, the system achieves 242 FPS, which likely approaches the CPU's limit in this engine, while at 4K Ultra the GPU takes over and delivers 84 FPS.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 242 FPS average, Medium produces 198 FPS (with a minimum of 168 and maximum of 227), High yields 149 FPS, and Ultra drops to 142 FPS. The gap between Low and Ultra is exactly 100 FPS, showing that the CPU can maintain high throughput even when visual complexity increases.

Moving to 2560x1440, the frame rates remain impressive but scale down proportionally. Low settings hit 205 FPS, Medium averages 159 FPS (minimum 136, maximum 183), High reaches 120 FPS, and Ultra settles at 114 FPS. The delta between Low and Ultra here is 91 FPS, slightly narrower than at 1080p, suggesting the GPU is beginning to absorb more of the workload.

At 3840x2160, the results show the most significant drop. Low settings still manage 151 FPS, which is remarkable for 4K. Medium averages 118 FPS (minimum 100, maximum 135), High drops to 88 FPS, and Ultra falls to 84 FPS. The gap between Low and Ultra at 4K is 67 FPS, indicating that the GPU is now the dominant constraint, but the system never falls below playable territory even at maximum settings.

The Medium preset at each resolution includes min/max data, which provides insight into frame time consistency. At 1080p Medium, the range from 168 to 227 FPS represents a 35% spread, while at 4K Medium, the range from 100 to 135 FPS is a similar 35% spread. This consistency across resolutions suggests the frame pacing remains stable regardless of resolution, a positive sign for flight sim enthusiasts who need predictable performance during complex scenery loads.

Resolution Scaling

The transition from 1080p to 4K reveals a clear picture of component scaling. At Low settings, the system drops from 242 FPS at 1080p to 205 FPS at 1440p (a 15% reduction) and then to 151 FPS at 4K (a 38% reduction from 1080p). This pattern indicates that at Low settings, the CPU is the primary driver, as the GPU has plenty of headroom even at 4K.

At Ultra settings, the scaling is steeper: 142 FPS at 1080p drops to 114 FPS at 1440p (a 20% reduction) and then to 84 FPS at 4K (a 41% reduction from 1080p). The steeper drop at Ultra settings confirms that the GPU becomes more involved as visual complexity increases, but the fact that 4K Ultra still holds 84 FPS suggests neither component is fully overwhelmed.

The data points to a system where the CPU's single-thread performance (Cinebench R23 score of 4,648) is the limiting factor at lower resolutions and settings, while the GPU's massive compute resources (104.8 TFLOPS FP32) take over at higher resolutions. The 32 GB VRAM ensures that texture memory is never a concern, which is why the scaling from 1080p to 4K follows a predictable pattern rather than showing sudden drops from memory exhaustion.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. Its base clock of 3.50 GHz boosts to 5.10 GHz, with 24 MB of shared L3 cache and 3 MB of L2 cache per core. The CPU's memory bandwidth of 102.4 GB/s over dual-channel DDR5 provides adequate throughput for this simulator, though it's not exceptional by modern standards.

In Microsoft Flight Simulator, the CPU's single-thread performance matters most. The Cinebench R23 single-core score of 4,648 places it in a competitive position, while the multi-core score of 32,924 shows the 14 cores can handle background tasks and scenery generation without interfering with the main rendering thread. The PassMark single-thread score of 4,394 corroborates the Cinebench results, suggesting consistent single-thread capability across different benchmark methodologies.

The CPU's 90th percentile ranking among all CPUs means it outperforms the vast majority of processors on the market, yet its nearest rivals in average benchmark score include the AMD Ryzen 9 7900 (49,228 vs. 48,995, a 0.5% difference) and the Intel Core i5-14600K (48,618, 0.8% slower). These close margins indicate the Core Ultra 5 245 sits at a performance tier where small differences in clock speed or cache architecture can shift rankings. The lack of multiplier unlocking means enthusiasts cannot overclock to close any perceived gaps, but the data shows this is unnecessary for this game.

Settings Recommendations

For players prioritizing maximum frame rates, the Low preset at any resolution delivers exceptional performance: 242 FPS at 1080p, 205 FPS at 1440p, and 151 FPS at 4K. These numbers exceed the refresh rates of virtually all consumer monitors, making Low a viable option for competitive or fast-paced flying where responsiveness matters more than visual fidelity.

The Medium preset offers a balanced experience. At 1080p, it delivers 198 FPS average with a minimum of 168, ensuring smooth gameplay even during complex scenes. At 1440p, the 159 FPS average with a 136 FPS minimum maintains high refresh rates, while 4K Medium's 118 FPS average (100 minimum) remains well above the 60 FPS threshold for comfortable play. The Medium preset's min/max data shows consistent frame pacing, making it the recommended choice for most users.

High settings provide diminishing returns in terms of visual improvement per frame rate cost. The jump from Medium to High reduces frame rates by approximately 25% across all resolutions (198 to 149 at 1080p, 159 to 120 at 1440p, 118 to 88 at 4K), while the visual difference between these presets is typically modest in flight simulators. Ultra settings cost an additional 5-10% performance over High, with 4K Ultra at 84 FPS still being playable but showing the system's limits.

The data suggests that for 4K users, Medium offers the best combination of visual quality and performance, as the 118 FPS average provides headroom for the 100 FPS minimum. For 1440p users, High at 120 FPS is a strong choice, while 1080p users can comfortably run Ultra at 142 FPS without sacrificing smoothness. The measured results indicate this combo excels at maintaining high frame rates across all settings, but the most efficient use of the hardware — where performance per visual quality is highest — lies with the Medium preset at 4K or the High preset at 1440p.
