Downfall

Downfall, a 2016 horror title, exhibits significant performance scaling across the tested resolutions and settings on the Intel Core Ultra 7 265K and NVIDIA GeForce RTX 3080 platform. The measured data reveals a system that is capable of delivering high frame rates, but the balance between CPU and GPU load shifts dramatically depending on the chosen configuration. The RTX 3080, with its 10 GB of GDDR6X memory and 760.3 GB/s bandwidth, paired with the 20-core Ultra 7 265K, creates a pairing that is well-suited for this title, though the data shows clear limitations at the highest settings and resolution.

Resolution Scaling

The frame rate progression from 1080p to 4K on the RTX 3080 exhibits the expected trend of decreasing performance as pixel count increases, but the rate of decline is not uniform across settings. At the High preset, performance falls from 200.3 FPS at 1920x1080 to 144.8 FPS at 2560x1440, a reduction of approximately 27.7%. Moving to 3840x2160, the average FPS drops further to 88, which is a 56.1% decrease from the 1080p baseline. This scaling pattern indicates that while the GPU is heavily utilized, the CPU is still providing ample headroom at 1080p, and the load only fully shifts to the graphics card as the resolution increases.

The scaling behavior is even more pronounced when examining the Low preset. At 1920x1080, the system pushes an average of 297.2 FPS, which is an exceptionally high number that suggests a CPU-bound scenario. At 2560x1440, the average FPS remains high at 216.2, but the drop of 27.3% mirrors the High preset's percentage change. However, at 4K, the Low preset yields 133.5 FPS. This represents a 55.1% drop from the 1080p figure, showing that the GPU becomes the primary limiting factor at this resolution, even with reduced graphical loads.

The Ultra preset tells a different story, as it places the most significant strain on the graphics card. Performance starts at 127.3 FPS at 1080p, which is lower than the High preset, indicating the additional graphical effects are already taxing the GPU. At 1440p, the average FPS falls to 87.8, and at 4K, it plummets to 57.2 FPS. The scaling from 1440p to 4K shows a massive 34.9% performance loss, highlighting that the RTX 3080's memory bandwidth and compute resources are saturated by the Ultra settings at higher resolutions. The data suggests that the RTX 3080 is the definitive limiting component at 4K, particularly when settings are raised, while the Ultra 7 265K's 20 cores and 5.50 GHz boost clock are more than sufficient to feed the GPU at lower resolutions.

Settings Recommendations

Analyzing the measured FPS rows, the High preset provides the most balanced experience for this hardware combination. At 1920x1080, it offers 200.3 FPS, which is well above the refresh rate of most high-end monitors. At 2560x1440, it still delivers 144.8 FPS, which is an excellent result for high-refresh-rate gaming. Even at 4K, the High preset maintains an average of 88 FPS, which is playable and smooth for a horror title. The Ultra preset, while visually superior, demands a heavy toll, reducing frame rates to 57.2 FPS at 4K and 87.8 FPS at 1440p. These numbers are playable but represent a significant compromise in smoothness.

The Low preset maximizes frame rates, reaching 297.2 FPS at 1080p, but this comes at the cost of visual fidelity. The Medium preset offers a middle ground, with 243 FPS at 1080p and 108.2 FPS at 4K. For the best overall experience, the High preset is the clear recommendation. It provides a substantial visual upgrade over Medium while retaining frame rates that are 64% higher than Ultra at 4K and 65.2% higher at 1440p. The data indicates that the RTX 3080's 10 GB VRAM is sufficient for High settings, as the performance drop from Medium to High is less severe than the drop from High to Ultra, which likely involves more demanding memory and compute features.

Measured FPS Breakdown

The complete set of measured frame rates shows a clear hierarchy across settings. At 1920x1080, the Low preset leads with 297.2 FPS, followed by Medium at 243 FPS, High at 200.3 FPS, and Ultra at 127.3 FPS. This order is consistent at 2560x1440, where Low achieves 216.2 FPS, Medium 173.5 FPS, High 144.8 FPS, and Ultra 87.8 FPS. The same pattern holds at 3840x2160, with Low at 133.5 FPS, Medium at 108.2 FPS, High at 88 FPS, and Ultra at 57.2 FPS.

The differences between presets are substantial. At 1080p, the Ultra preset is 57.2% slower than High. At 1440p, this gap widens to 39.4%, and at 4K, Ultra is 35.0% slower than High. The gap between Low and Medium is also notable, with Medium being 18.2% slower at 1080p, 19.7% slower at 1440p, and 18.9% slower at 4K. The performance deltas indicate that the step from Medium to High is more costly than from Low to Medium, but less costly than from High to Ultra. The system's low frame rate of 57.2 FPS at 4K Ultra is the only instance where the average dips below 60 FPS, making it the only configuration that may not be ideal for smooth gameplay on standard 60Hz displays.

GPU Role

The NVIDIA GeForce RTX 3080, based on the Ampere architecture and GA102 chip, is the primary driver of graphics performance in Downfall. Its 10 GB of GDDR6X memory on a 320-bit bus provides a bandwidth of 760.3 GB/s, which is crucial for handling the high-resolution textures and effects in the game. The GPU's boost clock of 1710 MHz and its 8704 shading units allow it to process the complex shaders and lighting effects that are characteristic of a horror title. The measured data shows that the GPU's performance scales predictably with resolution, but its capabilities are stretched at 4K with the Ultra preset, where the average FPS drops to 57.2.

The RTX 3080's 68 RT cores are present, though Downfall is a 2016 title and likely does not utilize hardware ray tracing. The GPU's compute capabilities, evidenced by its 29.77 TFLOPS FP32 performance and a Passmark G3D score of 25086, are more than adequate for this game. The GPU sits in the 80th percentile of all GPUs, and its nearest rivals include the AMD Radeon RX 7900 GRE, which is 0.9% faster in average benchmark scores, and the AMD Radeon 880M, which is 0.4% faster. In practice, the RTX 3080's performance in Downfall is strong, but the 4K Ultra results show that its 10 GB memory pool and processing power are the limiting factors at the highest settings.

CPU Role

The Intel Core Ultra 7 265K, with its 20 cores and 20 threads, plays a critical role in ensuring the RTX 3080 is fed with data. The CPU's high boost clock of 5.50 GHz and its 30 MB of shared L3 cache provide the responsiveness needed for high-frame-rate scenarios. The benchmark data for the CPU shows exceptional performance, with a Cinebench R23 multi-core score of 50009 and a single-core score of 7060, placing it in the 97th percentile of all CPUs. In Downfall, the CPU's influence is most evident at lower resolutions, where the frame rates are extremely high. At 1080p Low, the system produces 297.2 FPS, which suggests the CPU is capable of processing the game's logic and draw calls faster than the GPU can render them.

The CPU's nearest rivals include the Intel Core i9-14900K, which is 0.9% slower in average benchmark scores, and the Intel Core Ultra 7 265KF, which is 0.2% slower. This level of performance indicates that the Ultra 7 265K is not a bottleneck in most scenarios. The data shows that even at 1440p with High settings, the CPU can maintain a 144.8 FPS average, demonstrating its ability to keep up with the GPU's output. Only at 4K, where the GPU's rendering load becomes the dominant factor, does the CPU's role diminish. The 125W TDP and the "Arrow Lake" architecture, built on a 3 nm process, contribute to its efficiency, but the core takeaway from the benchmark results is that the CPU provides a solid foundation for the RTX 3080, enabling the high frame rates seen at 1080p and 1440p.
