# Microsoft Flight Simulator: Intel Core Ultra 5 245 + NVIDIA GeForce RTX 4070

This combination of the Intel Core Ultra 5 245 and NVIDIA GeForce RTX 4070 delivers a compelling flight simulation experience, though the data reveals distinct performance ceilings depending on resolution. The measured FPS across 1080p, 1440p, and 4K resolutions at Low, Medium, High, and Ultra presets shows a system that scales predictably with visual demands, but the character of that scaling tells an important story about where each component's influence dominates. With a combo rank of 833 out of 3714 tested configurations, this pairing sits comfortably in the upper quarter of all tested systems, though the specific bottlenecks shift meaningfully as resolution increases.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals a system that transitions from CPU-bound at lower resolutions to GPU-bound at higher ones. At Low settings, the average FPS falls from 165 at 1080p to 133 at 1440p, a decline of approximately 19%, and then to 98 at 4K, representing a further 26% reduction. This steep scaling at Low settings strongly suggests the CPU is the primary limiter at 1080p, since the GPU has ample headroom to render frames quickly when visual complexity is minimal. The fact that 1080p Low produces 165 FPS while 1440p Low produces 133 FPS indicates the rendering load is still modest enough that the processor's capabilities are being stretched.

At Medium settings, the scaling pattern shifts noticeably. The 1080p result of 128 FPS drops to 103 FPS at 1440p (a 19.5% decline) and then to 76 FPS at 4K (a 26.2% further drop). This consistent reduction pattern suggests the GPU begins to take on more responsibility as settings increase, though the CPU still plays a significant role. The High preset shows 96 FPS at 1080p, 78 FPS at 1440p (18.75% drop), and 57 FPS at 4K (26.9% drop). The percentage declines remain remarkably consistent across presets, which indicates a well-balanced system where neither component completely dominates the scaling curve.

Ultra settings present the most demanding scenario, with 92 FPS at 1080p dropping to 74 FPS at 1440p (19.6% decline) and then to 55 FPS at 4K (25.7% decline). The fact that 4K Ultra produces just 55 FPS while 4K Low produces 98 FPS illustrates the massive GPU workload increase that comes with maximum visual fidelity. The data clearly shows that 4K Ultra is approaching the practical limits of this configuration, while 1080p Low leaves substantial performance on the table that the CPU cannot fully utilize.

CPU Role

The Intel Core Ultra 5 245 brings 14 cores and 14 threads to this flight simulator, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz. This Arrow Lake-S architecture processor, built on a 3 nm process by TSMC, demonstrates strong single-threaded performance with a Cinebench R23 single-core score of 4648 and a multi-core score of 32924. The PassMark single-thread score of 4394 and multithread score of 38706 further confirm that this CPU has substantial compute capabilities for simulation workloads.

Microsoft Flight Simulator is known for its heavy reliance on single-thread performance for game logic and physics calculations, and the data supports this expectation. At 1080p Low settings, the system achieves 165 FPS, which is likely near the CPU's practical limit for this game's engine. The fact that increasing resolution to 1440p at Low settings only drops performance to 133 FPS (a 19% reduction) while the GPU workload increases by roughly 80% in pixel count suggests the CPU is still the primary constraint at these settings.

The processor's 24 MB of shared L3 cache and 3 MB per-core L2 cache provide adequate data locality for flight simulation's complex world streaming. The 102.4 GB/s memory bandwidth from dual-channel DDR5 support helps feed the simulation's data-intensive nature. The CPU's 90th percentile ranking among all tested CPUs places it well above average, and its nearest rivals include the AMD Ryzen 9 7900 (0.5% faster average) and Intel Core i5-14600K (0.8% slower), indicating the Ultra 5 245 sits in competitive territory for this workload.

Settings Recommendations

The measured data provides clear guidance on which preset offers the optimal balance of visual quality and frame rate. At 4K, the High preset delivers 57 FPS average, which is playable but below the 60 FPS threshold many simmers prefer. The Medium preset at 4K produces 76 FPS with a minimum of 65 FPS and maximum of 88 FPS, making it the most sensible choice for 4K displays when smoothness matters more than absolute visual fidelity. The 4K Ultra preset's 55 FPS average is only slightly below High but demands significantly more from the GPU, making it a marginal tradeoff.

At 1440p, the High preset achieves 78 FPS average, which provides a good balance of visual quality and performance. The Medium preset at 1440p delivers 103 FPS with a minimum of 88 FPS, ensuring consistent frame pacing during complex scenery. The Ultra preset at 1440p produces 74 FPS, which remains playable while offering maximum visual detail. Given that the difference between High and Ultra at 1440p is only 4 FPS, Ultra becomes an attractive option for users with 1440p monitors.

The 1080p results show that High settings at 96 FPS offer an excellent experience, while Medium at 128 FPS provides additional headroom for demanding scenarios like dense urban areas or stormy weather. The 1080p Ultra preset at 92 FPS is only 4 FPS slower than High, making Ultra the recommended choice for 1080p users who want maximum visual quality without sacrificing playability. The Low preset at 1080p produces 165 FPS, but this sacrifices too much visual detail for a flight simulator where situational awareness depends on visual clarity.
