Downfall

Resolution Scaling

The measured frame rates across resolutions reveal a predictable scaling pattern, but the shape of that curve tells a story about where this system's limits lie. At 1080p Low, the combination of the AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 4090 produces a staggering 442 FPS average. That number climbs down to 315 FPS at 1440p Low and further to 196 FPS at 4K Low. The drop from 1080p to 1440p at Low settings is roughly 29%, and the drop from 1440p to 4K is another 38%. This is a steep decline, but it is not uniform.

The scaling becomes more telling when examining the High preset. At 1080p High, the system delivers 296 FPS. At 1440p High, it drops to 212 FPS, a reduction of about 28%. At 4K High, the average falls to 132 FPS, another 38% cut. The consistency of these percentage drops—hovering around 28-29% for the first step and 37-38% for the second—suggests that the RTX 4090 is still the primary driver of performance even at lower resolutions. If the CPU were the bottleneck, we would expect to see a much smaller delta between 1080p and 1440p, as the processor would be maxed out in both scenarios.

However, the absolute numbers at 1080p Low (442 FPS) and even 1080p Ultra (185 FPS) indicate that the CPU is doing its part to feed the GPU. The data suggests that this pairing is well-balanced for high-refresh-rate gaming at 1440p, where the 212 FPS at High settings leaves ample headroom for a 240Hz display. At 4K, the system is clearly GPU-bound, with the 132 FPS at High being a strong result for a horror title but showing the expected stress of 8.3 million pixels. The scaling from Medium to Ultra at 4K is particularly sharp—from 161 FPS down to 82 FPS—which implies that the Ultra preset introduces effects that are disproportionately expensive at high pixel counts. This resolution scaling analysis points to a system that is overkill for 1080p, excellent for 1440p, and very capable but not unlimited at 4K.

How This Combo Ranks

In the game Downfall, this specific combination of CPU and GPU achieves a combo rank of 90 out of 2,928 tested combos. That places it in the top 3.1% of all configurations recorded in the database. This is a dominant position, reflecting that the pairing of a high-core-count X3D processor with the flagship RTX 4090 is near the apex of what is available for this horror title. The rank is a composite measure, but the FPS data indicates that the system is not leaving performance on the table at any resolution.

When looking at the individual component rankings, the CPU sits at the 91st percentile among all processors, while the GPU is at the 88th percentile among all graphics cards. The fact that the combo rank (90th out of 2,928) is higher than the GPU's individual percentile suggests that the CPU is doing an excellent job of complementing the GPU in this specific game. The Ryzen 9 9900X3D's nearest rivals in average benchmark score include the Intel Core Ultra 5 245KF, which is a mere 0.6% slower, and the Intel Core Ultra 5 245K, which is 1.3% faster. This places the AMD chip in a tight competitive cluster at the top of the CPU charts. The RTX 4090's nearest rivals, such as the Intel Arc Pro A60 and AMD Radeon Pro Vega 48, are effectively tied with it in pure compute benchmarks (0% and 0.3% deltaPct respectively), but those are professional workstation cards that do not have the gaming-specific optimizations of the 4090.

The data indicates that users with this combo are unlikely to find a faster experience in Downfall without moving to a multi-GPU setup, which is not supported in most modern titles. The rank of 90 is particularly impressive given that the database includes over 2,900 combinations, many of which feature the same GPU with lesser CPUs. This suggests that the 9900X3D is extracting more performance from the 4090 than many other processors would. The benchmark results show a system that is in the top tier of gaming performance, with the CPU and GPU working in concert rather than one holding the other back.

GPU Role

The NVIDIA GeForce RTX 4090 is the undisputed workhorse of this configuration. Its specifications are formidable: a 24 GB GDDR6X memory pool on a 384-bit bus delivering 1.01 TB/s of bandwidth, and a boost clock of 2520 MHz. The GPU is built on the Ada Lovelace architecture using a 5 nm process at TSMC, packing 76,300 million transistors into a 609 mm² die. This hardware translates directly into the frame rates seen in Downfall. The 24 GB of VRAM is far beyond what this 2016 horror game requires, meaning there is zero risk of texture thrashing or memory-related stutters at any resolution, even with the Ultra preset. The massive bandwidth ensures that the GPU can feed its 16,384 shading units at 4K without waiting on memory.

The RTX 4090's benchmark scores reinforce its position. It posts a Passmark G3D score of 38,194 and a Geekbench Vulkan score of 271,631. In the 3DMark Steel Nomad DX12 test, it scores 9,223. These synthetic results align with the real-world gaming data: the GPU is capable of producing 442 FPS at 1080p Low, which is far beyond what most displays can even refresh. The fact that it drops to 196 FPS at 4K Low shows that even this behemoth is challenged by the pixel count but remains exceptionally fast. The GPU's 128 RT cores and 512 tensor cores are present, but in a game like Downfall that predates widespread ray tracing, these are largely idle.

The 4090's performance in this game is best described as "headroom." At 1440p High, the 212 FPS average suggests the GPU is not fully saturated, leaving room for higher refresh rates or more demanding visual mods. The measured FPS data shows a linear scaling of performance with resolution, which is characteristic of a GPU that is not being bottlenecked by the CPU. The GPU's nearest rivals in synthetic benchmarks, such as the AMD Radeon Pro W6600M (which is 2.5% slower) and the AMD Radeon PRO V710 (which is 2.9% faster), do not reflect gaming performance; the 4090's dominance in actual game tests is far more pronounced. The card's 450 W TDP and triple-slot cooler are the price of this performance, but the benchmark data shows it is a price worth paying for those seeking maximum frame rates.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across the three most common resolutions and four quality presets. Starting at 4K (3840x2160), the system produces 196 FPS on Low, 161 FPS on Medium, 132 FPS on High, and 82 FPS on Ultra. The Medium preset offers a minimum FPS of 136 and a maximum of 185, showing a tight frame time distribution. The jump from Low to Medium is a 17.8% performance hit, while the jump from Medium to High is 18% and from High to Ultra is a massive 37.8%. This indicates that the Ultra preset at 4K is exceptionally demanding, likely using effects that are not optimized for this resolution.

At 1440p (2560x1440), the numbers are significantly higher. Low settings yield 315 FPS, Medium produces 258 FPS, High reaches 212 FPS, and Ultra drops to 132 FPS. The Medium preset here shows a min of 219 and a max of 297 FPS. The scaling pattern is similar to 4K, but the absolute frame rates are high enough that even Ultra is playable on a high-refresh-rate monitor. The 1440p High result of 212 FPS is a sweet spot for competitive play, while 1440p Ultra at 132 FPS is still smooth for a horror title where immersion matters more than twitch reaction times.

At 1080p (1920x1080), the system is almost absurdly fast. Low settings produce 442 FPS, Medium delivers 361 FPS, High hits 296 FPS, and Ultra still manages 185 FPS. The Medium preset has a min of 307 and a max of 416 FPS. This data suggests that at 1080p, the CPU is beginning to become a factor, as the GPU has so much headroom that it is waiting for the processor to feed it data. The 442 FPS at Low is likely near the practical limit of what the Ryzen 9 9900X3D can push in this title. The frame rates at 1080p are so high that they exceed the refresh rate of virtually all monitors on the market, making this resolution a waste of the system's potential. The data across all resolutions shows a consistent hierarchy: Low > Medium > High > Ultra, with the delta between presets growing as resolution increases.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combination depend heavily on the target resolution and refresh rate. At 4K, the Ultra preset's 82 FPS average is playable but leaves little headroom for frame time spikes, and the lack of a reported minimum FPS for this setting is a concern. The High preset at 4K produces 132 FPS, which is a 61% improvement over Ultra and is far smoother for a horror game that relies on atmospheric tension. Given that the RTX 4090 has ample VRAM and the game is from 2016, the High preset at 4K is the recommended balance of visual fidelity and performance. The Medium preset at 4K (161 FPS) is also viable for those who prioritize frame rate above all else, but the visual downgrade from High is noticeable in a genre where lighting and shadow play are crucial.

At 1440p, the data supports using the High preset as the default. The 212 FPS average is well above the 144Hz refresh rate that most high-end monitors offer, and it provides enough headroom to avoid drops below 165 FPS in most scenes. The Ultra preset at 1440p (132 FPS) is also a strong choice, as it delivers the best visual quality while still being smooth. The difference between High and Ultra at 1440p is a 37.7% performance hit, which is significant, but the base frame rate is high enough that the cost is acceptable. For competitive play, the Medium preset at 1440p (258 FPS) would be the choice, as it ensures the frame rate never dips below 219 FPS.

At 1080p, the recommendation is to avoid the Low and Medium presets entirely. The 442 FPS and 361 FPS averages respectively are excessive and offer no tangible benefit over High, as most displays cap out at 240Hz or 360Hz. The High preset at 1080p (296 FPS) is the sweet spot, providing excellent visual quality while still maxing out any consumer display. The Ultra preset at 1080p (185 FPS) is also viable and is arguably the best choice for a horror game where visual fidelity enhances the atmosphere. In summary, the data suggests that High is the universal recommendation across all resolutions, with Ultra being a viable alternative at 1440p and 1080p for those who value graphics over frame rate. The Medium preset is only recommended for competitive play at 1440p, and the Low preset is essentially pointless with this hardware.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge) built on a 4 nm TSMC process. It features a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with a 128 MB L3 cache. This large cache is particularly beneficial in gaming, and the benchmark data in Downfall reflects this. The CPU's Cinebench R23 multicore score of 47,737 and single-core score of 6,739 are strong, but the gaming performance is where the 3D V-Cache design shines. In Downfall, the CPU is able to maintain high minimum frame rates, as evidenced by the 4K Medium preset's 136 FPS minimum, which is only a 15.5% drop from the average.

The CPU's role becomes more apparent at lower resolutions. At 1080p Low, the 442 FPS average is likely near the engine's limit, and the CPU is the limiting factor at this point. The fact that the 1080p High preset (296 FPS) is only 33% lower than the Low preset (442 FPS) suggests that the CPU is still able to feed the GPU effectively even as the GPU load increases. The 9900X3D's nearest rival, the Intel Core Ultra 5 245KF, is only 0.6% slower in average benchmark score, but the AMD chip's gaming-specific advantages (likely the 128 MB L3 cache) give it an edge in this horror title. The CPU's percentile ranking of 91st among all processors indicates it is in the top 9% of all CPUs tested, and its 12 cores are more than sufficient for a game from 2016 which likely uses fewer than 8 threads.

The benchmark data shows that the CPU is not a bottleneck at 4K, where the GPU is clearly the limiting factor. However, at 1080p, the CPU's performance is what enables the system to hit 442 FPS. The 9900X3D's 24 threads ensure that any background tasks or streaming software will not interfere with game performance. The CPU's power draw of 120 W TDP is modest given its performance, allowing it to maintain high boost clocks without thermal throttling. Overall, the CPU's role in this system is to provide a massive performance ceiling that ensures the RTX 4090 is never starved for data, and the measured FPS data confirms that the 9900X3D accomplishes this task admirably.
