Microsoft Flight Simulator

Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the AMD Ryzen 7 7700X and NVIDIA GeForce RTX 5070 Ti reveals a clear pattern of scaling as resolution increases. At 1920x1080 with Ultra settings, the combo produces an average of 110.8 FPS. Moving to 2560x1440 at Ultra drops this to 90.5 FPS, and at 3840x2160 at Ultra, the average falls further to 63.2 FPS. This represents a 43% reduction in frame rate from 1080p to 4K at the highest settings, indicating that the GPU is becoming the primary limiting factor as pixel count grows.

However, the scaling behavior changes dramatically when settings are lowered. At Low settings, the 1080p result is 199.1 FPS, dropping to 161.4 FPS at 1440p and 117.7 FPS at 4K. The percentage drop from 1080p to 4K at Low settings is roughly 41%, which is similar to the Ultra drop, but the absolute numbers are much higher. This suggests that even at 4K Low, the frame rate is high enough that the CPU's single-thread performance and the game's engine overhead play a more significant role than at Ultra settings, where the GPU is saturated more quickly.

The gap between Low and Ultra at each resolution is telling. At 1080p, the difference is 88.3 FPS (199.1 vs 110.8), while at 4K, the difference narrows to 54.5 FPS (117.7 vs 63.2). This narrowing gap is a classic sign of GPU-bound behavior. As resolution increases, the RTX 5070 Ti's rendering workload grows, and the CPU has more headroom to feed it, making the GPU the bottleneck. The 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are likely sufficient for the texture and geometry loads at 4K, but the raw shader throughput becomes the deciding factor.

The data shows that for users targeting 4K Ultra, the RTX 5070 Ti is just above the 60 FPS threshold, averaging 63.2 FPS. Dropping to High settings at 4K yields 66.9 FPS, which is a modest gain of only 3.7 FPS over Ultra. This indicates that the Ultra preset in this flight simulator is particularly demanding, and the GPU is already near its limits. At 1080p, the combo is clearly CPU-limited at Low settings, as the 199.1 FPS result is far beyond what most displays can show, and the CPU's 8 cores and 16 threads are likely being taxed by the simulation's physics and world streaming.

CPU Role

The AMD Ryzen 7 7700X is an 8-core, 16-thread processor from the 7000 series, based on the Zen 4 architecture with a 5 nm process. It has a base clock of 4.50 GHz and a boost clock of 5.40 GHz. In synthetic benchmarks, it scores 4,281 points in Cinebench R23 single-core and 30,325 points in multi-core. The single-core score is particularly relevant for Microsoft Flight Simulator, which typically relies heavily on a single thread for the main simulation loop. The boost clock of 5.40 GHz indicates strong single-thread capability, which helps maintain high frame rates when the GPU is not the bottleneck.

The 7700X's multi-threaded performance is also substantial, with a Cinebench R23 multi-core score of 30,325 and a Geekbench multi-core score of 15,538. This benefits the game's background tasks, such as terrain loading, AI traffic, and weather simulation. The 32 MB of shared L3 cache helps reduce memory latency, which is crucial for the complex data structures used in a flight simulator. The CPU's percentile ranking against all CPUs is 89, meaning it outperforms the vast majority of processors in the database.

When comparing to its nearest rivals, the 7700X's average benchmark score is 34,313. The Intel Core i5-13500 scores 34,175, which is 0.4% lower, and the Intel Core i7-12800HX scores 34,136, 0.5% lower. The Intel Core Ultra 7 165H scores 34,584, which is 0.8% higher, and the AMD EPYC 4244P scores 34,599, 0.8% higher. These small deltas suggest that the 7700X is essentially in the same performance tier as these CPUs for general workloads. However, in the measured game data, the 7700X's high boost clock appears to give it an edge in maintaining high average FPS at lower resolutions.

The data suggests that at 1080p Low, the CPU is the limiting component. The 7700X's 8 cores are enough to handle the game's simulation, but the 5.40 GHz boost clock is what allows it to push frame rates to nearly 200 FPS. At 4K Ultra, the CPU has ample headroom, and the frame rate is almost entirely determined by the GPU. The transition point appears to be around 1440p High, where the combo achieves 94.6 FPS, showing a balance where neither component is fully saturated.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is built on the Blackwell 2.0 architecture with a 5 nm process and features 16 GB of GDDR7 memory on a 256-bit bus, providing a memory bandwidth of 896.0 GB/s. The GPU has a base clock of 2295 MHz and a boost clock of 2452 MHz. It has 8,960 shading units, 280 TMUs, and 96 ROPs, with 70 RT cores and 280 tensor cores. The FP32 performance is rated at 43.94 TFLOPS. The GPU's percentile ranking is 87, and its average benchmark score is 52,086.

In the game's measured FPS, the RTX 5070 Ti shows its strength in resolution scaling. At 4K Ultra, it averages 63.2 FPS, which is a playable frame rate for a simulation title. The 16 GB VRAM is likely sufficient for the high-resolution textures used in Microsoft Flight Simulator, even at Ultra settings. The 896.0 GB/s bandwidth ensures that texture streaming and loading do not become a bottleneck, which is critical in a game that streams scenery data continuously. The boost clock of 2452 MHz helps maintain consistent performance during demanding scenes with complex lighting and shadows.

The GPU's nearest rivals, based on average benchmark score, include the NVIDIA GeForce RTX 4080 with a score of 52,085 (0% delta), the AMD Radeon RX 7700S with 52,505 (-0.8%), the NVIDIA RTX A1000 with 50,826 (2.5%), and the AMD Radeon Pro W6600M with 53,414 (-2.5%). This places the RTX 5070 Ti in the same performance class as the RTX 4080, which is notable. However, the measured FPS data shows that the RTX 5070 Ti is capable of handling 4K Ultra with an average above 60 FPS, indicating that its 43.94 TFLOPS of FP32 performance is well-suited for this game's GPU-intensive rendering.

The data indicates that the GPU becomes the primary bottleneck at 4K settings. The difference between High and Ultra at 4K is only 3.7 FPS (66.9 vs 63.2), suggesting that the Ultra preset adds significant shading work that the RTX 5070 Ti can barely handle. At 1080p, the GPU is heavily underutilized, as evidenced by the 199.1 FPS at Low settings, which is far beyond the CPU's ability to feed it consistently. This confirms that the RTX 5070 Ti is a high-end GPU that is best paired with a strong CPU to avoid leaving performance on the table at lower resolutions.

How This Combo Ranks

In the database of tested combinations, the AMD Ryzen 7 7700X and NVIDIA GeForce RTX 5070 Ti combo ranks 144th out of 1,795 total combos for Microsoft Flight Simulator. This places it in the top 8% of all tested configurations, indicating strong overall performance. The rank is based on the measured FPS across all resolutions and settings, and it reflects the balance between the CPU's high single-thread performance and the GPU's robust 4K capabilities.

The rank of 144 suggests that there are 143 other combos that achieve higher average FPS in this game, likely with more powerful GPUs like the RTX 5090 or CPUs with higher boost clocks. However, the 7700X and RTX 5070 Ti combo is clearly a high-end pairing. The CPU's percentile rank of 89 and the GPU's percentile rank of 87 align well with the overall combo rank, showing that both components are in the upper echelon of their respective categories.

The measured data shows that this combo is particularly strong at 1440p, where it achieves 90.5 FPS at Ultra and 161.4 FPS at Low. This makes it an excellent choice for high-refresh-rate 1440p displays. At 4K, the combo is still capable of delivering a smooth experience at High settings, with 66.9 FPS, which is above the 60 FPS target for most players. The rank of 144 out of 1,795 confirms that this is a top-tier combination for flight simulation enthusiasts who want a balance of resolution and frame rate.
