Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that stresses both the CPU and GPU heavily, and the combination of an Intel Core Ultra 5 235 with an NVIDIA GeForce GTX 1650 produces a specific performance profile that is worth examining closely. The measured frame rates across resolutions and settings reveal a system that is firmly limited by the graphics card, yet the processor’s capabilities still set the ceiling for what is achievable in this simulation. This analysis breaks down the data from the benchmark rows to show exactly where this combo stands, how it scales, and what settings make the most sense for a playable experience.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, which points directly at the GPU as the primary bottleneck in this pairing. At 1080p with Low settings, the combo averages 48 FPS, which is the highest measured result across the entire dataset. Moving to 1440p at the same Low preset drops that average to 39 FPS, a reduction of 9 frames. At 4K Low, the average falls further to 29 FPS, meaning the jump from 1080p to 4K alone costs 19 FPS, or roughly a 40% loss in frame rate. This pattern is not unique to Low settings; it repeats across all presets, indicating that resolution scaling is the dominant factor in performance.

For High settings, the trend is similar but with lower absolute numbers. The 1080p High average is 28 FPS, which drops to 23 FPS at 1440p and then to 17 FPS at 4K. That is an 11 FPS difference between 1080p and 4K, which is a smaller absolute gap than Low but still represents a 39% reduction. Medium settings show 37 FPS at 1080p, 30 FPS at 1440p, and 22 FPS at 4K, with the measured minimum and maximum frames at each resolution confirming a tight band around the average. Ultra settings are the most punishing, with 27 FPS at 1080p falling to 22 FPS at 1440p and finally 16 FPS at 4K.

What this scaling tells us is that the GTX 1650 is the limiting component at every resolution. The Core Ultra 5 235, with its 14 cores and 14 threads, is not the constraint here; if the CPU were the bottleneck, we would expect to see smaller FPS differences between 1080p and 4K, because higher resolutions put more load on the GPU while the CPU work stays relatively constant. Instead, the data shows a nearly linear drop in performance as pixel count increases, which is the classic signature of a GPU-bound scenario. At 1080p, the GPU is already struggling to keep up with the simulation’s rendering demands, and at 4K it is simply overwhelmed, producing averages in the teens that are not comfortably playable.

The fact that the 1080p Low result of 48 FPS is the only measured average above 40 FPS across the entire table reinforces this interpretation. Even at the lowest settings and lowest resolution, the system cannot break 50 FPS, and every step up in resolution or quality pushes it further down. For someone targeting 4K, the data shows that even Low settings yield only 29 FPS, which is below the threshold for smooth gameplay in a flight simulator where camera movement and scenery loading demand consistent frame pacing. The GPU’s 4 GB of VRAM and 128-bit memory bus are likely contributing to this, but the resolution scaling alone is enough to identify the graphics card as the primary limiter.

GPU Role

The NVIDIA GeForce GTX 1650 is an end-of-life product from the GeForce 16-series, built on the Turing architecture with a TU117 chip. Its specifications include a base clock of 1485 MHz and a boost clock of 1665 MHz, with 4 GB of GDDR5 memory on a 128-bit bus providing 128.1 GB/s of bandwidth. The GPU has 896 shading units, 56 texture mapping units, and 32 raster output units, yielding a pixel rate of 53.28 GPixel/s and a texture rate of 93.24 GTexel/s. Its FP32 performance is 2.984 TFLOPS. These are modest figures by modern standards, and the benchmark results reflect that.

In the context of Microsoft Flight Simulator, the GTX 1650’s role is to render the complex scenery, aircraft models, and weather effects that the game generates. The data shows that its 4 GB VRAM is a limiting factor, especially at higher resolutions and settings. The measured FPS at 4K Ultra is 16 FPS, and at 1440p Ultra it is 22 FPS, suggesting that the card is not only compute-bound but also likely hitting memory capacity limits when texture detail is high. The lack of any ray tracing or tensor cores on this GPU (the relevant fields are null) means it cannot offload certain effects, leaving all rendering work to the traditional shader units.

The GPU’s average benchmark score is 7472, with a percentile rank of 40 among all GPUs, meaning it sits in the lower half of the performance distribution. Its nearest rivals include the AMD Radeon HD 8850M with an average score of 7447 (0.3% higher), the Intel UHD Graphics 750 at 7441 (0.4% higher), and the AMD Radeon R7 350 at 7425 (0.6% higher). The Intel Arc A310 is 1% faster with a score of 7550. These comparisons show that the GTX 1650 is performance-wise in the same bracket as integrated and low-end discrete solutions, which is consistent with the FPS results in this game.

The boost clock of 1665 MHz is the maximum the card can reach under load, but the actual sustained clock will depend on thermal and power limits. The card has a TDP of 75 W and requires no external power connectors, relying solely on the PCIe slot for power. This low power draw means it is unlikely to throttle severely, but it also caps the card’s performance headroom. In a flight simulator where the GPU is rendering vast distances and dense geometry, the 128.1 GB/s memory bandwidth is a clear bottleneck, as the card must constantly fetch texture data and geometry from VRAM. The measured FPS at 1080p Medium (37 FPS) versus 1080p Low (48 FPS) shows a 11 FPS drop, which is a larger percentage loss than the resolution scaling, indicating that memory pressure and shader load both rise significantly with quality settings.

Settings Recommendations

Given the measured data, the best experience with this combo is achieved at 1080p with Low settings, which produces an average of 48 FPS. This is the only configuration that approaches a playable frame rate for a simulator that benefits from smooth panning and responsive camera controls. The 1080p Medium preset drops to 37 FPS, which is still workable but may feel less fluid, and the measured minimum of 32 FPS suggests occasional dips that could be noticeable during complex scenes. At 1080p High, the average falls to 28 FPS, and at 1080p Ultra it is 27 FPS, both of which are below the 30 FPS threshold that many players consider the minimum for acceptable playability.

At 1440p, the situation worsens. The best result is 39 FPS at Low settings, which is playable but only just, and the Medium preset is 30 FPS with a minimum of 26 FPS, indicating that frame drops are common. High settings at 1440p yield 23 FPS, and Ultra drops to 22 FPS. For 4K, no setting produces a result above 29 FPS, which is the Low preset average, and the Medium preset’s minimum of 19 FPS is a clear sign that the game will stutter and struggle. The Ultra preset at 4K averages 16 FPS, making it effectively unplayable.

The data suggests that users should prioritize resolution over quality. Running at 1080p with Low settings is the only way to get close to 50 FPS, and that should be the default recommendation for anyone with this GPU. If a user is willing to accept lower frame rates, 1440p Low at 39 FPS is a viable alternative, but the hit to smoothness is significant. Moving to Medium or High settings at any resolution is not advisable, as the FPS drops below 30 in most cases. The measured rows show no configuration above 1080p Low that maintains a 40 FPS average, so the trade-off is clear: lower the resolution and settings to match the GPU’s capabilities, or accept a compromised frame rate.

For those who prioritize visual fidelity over frame rate, the 1080p Medium preset at 37 FPS is the best compromise, as it offers a moderate improvement in detail over Low while staying above 30 FPS on average. However, the minimum of 32 FPS means that busy areas with dense scenery will likely cause dips. The Ultra preset is not worth the FPS loss, as it only provides 27 FPS at 1080p, a mere 1 FPS improvement over High, which suggests that the GPU is already maxed out and the extra settings add little visual benefit for a significant performance cost.

How This Combo Ranks

In the overall ranking of tested CPU and GPU combinations for Microsoft Flight Simulator, this pairing holds a combo rank of 2885 out of 2996 combos. That places it in the bottom 4% of all tested configurations, which is a sobering statistic. The rank reflects the GTX 1650’s low standing in the GPU hierarchy, as the CPU itself is relatively strong. The Core Ultra 5 235 has a percentile rank of 89 among all CPUs, meaning it outperforms 89% of processors in general benchmark tests. This contrast between a high-performing CPU and a low-performing GPU creates a significant imbalance that limits the overall system’s capability in this game.

The combo rank is not surprising given the measured FPS data. With no resolution or settings combination breaking 50 FPS, and most configurations falling below 30 FPS, the system is clearly not competitive with higher-end builds. The fact that 2996 combos were tested means that only 111 perform worse, and those are likely combinations with even older or weaker GPUs. The GTX 1650’s average benchmark score of 7472 and its percentile rank of 40 place it in the lower half of all GPUs, and in a game as demanding as Microsoft Flight Simulator, that translates directly to poor performance.

The CPU’s strong standing does not help much here, because the game is GPU-bound at all tested settings. The Core Ultra 5 235’s nearest rivals in synthetic benchmarks include the AMD Ryzen AI 9 HX 375 with an average score of 46030 (0.1% slower), the Intel Core i9-13900HX at 46098 (0.1% faster), and the AMD EPYC 4364P at 45970 (0.2% slower). These are all high-performance processors, and the Core Ultra 5 235’s average benchmark score of 46062 puts it in that same class. However, in Microsoft Flight Simulator, the GPU is the deciding factor, and the GTX 1650 drags the entire combo down to the bottom of the rankings.

For a user looking at this data, the rank serves as a warning. This is not a combination that will deliver a satisfying experience in this game at higher settings or resolutions. The CPU has headroom to spare, but the GPU cannot take advantage of it. If the goal is to play Microsoft Flight Simulator, this combo is best suited for 1080p Low settings, and even then, the experience will be modest compared to what other configurations can achieve.

CPU Role

The Intel Core Ultra 5 235 is a desktop processor from the Core Ultra Series 2, based on the Arrow Lake architecture and manufactured on a 3 nm process by TSMC. It has 14 cores and 14 threads, with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The CPU’s cache hierarchy includes 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. It supports DDR5 memory in a dual-channel configuration, providing a memory bandwidth of 102.4 GB/s. The processor has a TDP of 65 W and uses the Intel Socket 1851. Its integrated graphics are Arc Xe-LPG Graphics with 24 execution units, though in this combo the discrete GTX 1650 handles all rendering.

In Microsoft Flight Simulator, the CPU’s role is to handle the simulation logic, physics, AI traffic, and the complex world-building that generates terrain and scenery on the fly. The game is known for being CPU-intensive, particularly at lower resolutions where the GPU is less of a bottleneck. The Core Ultra 5 235’s 14 cores and 14 threads provide substantial multi-threaded performance, as evidenced by its synthetic benchmarks. Its Cinebench R23 multi-core score is 14769, and its single-core score is 2085. The PassMark multi-thread score is 37816, and the single-thread score is 4516. These are strong results, placing the CPU in the 89th percentile of all CPUs.

However, the measured FPS data in this game shows that the CPU is not the limiting factor. At 1080p Low, the system achieves 48 FPS, but that is still below what a CPU with this level of performance could drive if paired with a more powerful GPU. The fact that the FPS drops significantly at higher resolutions, where the GPU’s workload increases, confirms that the CPU has headroom. The CPU’s boost clock of 5.00 GHz is high, and its single-thread performance is solid, which is important for a game that relies heavily on a main simulation thread. The L3 cache of 24 MB is shared across all cores, which helps with data access patterns in a game that streams large amounts of world data.

The Core Ultra 5 235’s nearest rivals in benchmark scores are all high-end processors, including the AMD Ryzen AI 9 HX 375 and the Intel Core i9-13900HX, which are mobile and HX-series parts designed for laptops. The fact that this desktop CPU matches them in average benchmark score (46062 versus 46030 and 46098 respectively) shows that it is a capable processor. Yet in this game, its performance is wasted because the GTX 1650 cannot keep up. If a user were to upgrade the GPU, the CPU would likely support significantly higher frame rates, but with the current combo, the CPU’s contribution is masked by the GPU’s limitations.
