Downfall

Downfall is a 2016 horror title that scales heavily with GPU throughput, and pairing an AMD Ryzen 5 2600 with an NVIDIA GeForce RTX 5090 produces a system where the graphics card is almost never the limiting factor at common gaming resolutions. The measured data shows a clear hierarchy: the RTX 5090 delivers massive frame rates across the board, but the older six-core Zen processor begins to show its age when the resolution drops and the CPU has to feed more frames per second. This combination ranks 266th out of 1741 tested combos for this game, placing it in the top 15% of all pairings, and the benchmark results indicate that users should focus on visual quality settings rather than chasing raw frame rate at lower resolutions.

Resolution Scaling

The frame rate drop from 1080p to 4K is significant but not as steep as one might expect from a flagship GPU, because the Ryzen 5 2600 starts to bottleneck the system before the RTX 5090 can fully stretch its legs. At Low settings, the average FPS moves from 250.5 at 1920x1080 down to 190.7 at 3840x2160 — a 23.9% reduction. This is a relatively mild penalty, suggesting that even at 4K Low, the GPU is not being pushed to its absolute limit. Moving to High settings, the drop is similar in percentage terms: 214.9 FPS at 1080p falls to 136.8 FPS at 4K, a 36.3% decline. The Ultra preset tells a different story: 179.9 FPS at 1080p drops to 84.1 FPS at 4K, a 53.2% reduction. That larger delta at Ultra indicates the GPU is finally becoming the primary constraint, as the heavier shading and texture work load the RTX 5090’s compute units more evenly.

Between 1440p and 4K, the scaling is more pronounced than between 1080p and 1440p. At Medium settings, 1440p yields 207.7 FPS while 4K drops to 168.2 FPS, a 19.0% hit. At High, the gap widens: 196.1 FPS at 1440p versus 136.8 FPS at 4K, a 30.2% reduction. The data suggests that 1440p is the sweet spot for this pairing, as the CPU can still keep up with the GPU’s output. At 1080p, the frame rates are high but the scaling between Low and Ultra is compressed — 250.5 to 179.9 FPS — which points to the CPU limiting the maximum achievable frame rate. The conclusion is that resolution scaling in Downfall is mostly GPU-bound at 4K Ultra, but CPU-bound at 1080p, with 1440p acting as the balanced middle ground.

Settings Recommendations

For the best experience per the measured rows, the High preset at 1440p offers the strongest combination of fluidity and visual fidelity. The average FPS of 196.1 is well above any refresh rate a typical gamer would use, and it stays within 13.8% of the Low preset’s 225.2 FPS at the same resolution. The jump from High to Ultra at 1440p is punishing: 196.1 FPS falls to 136.3 FPS, a 30.5% reduction, which is a heavy price for marginal visual gains in a horror game where atmosphere matters more than texture detail. At 4K, the High preset delivers 136.8 FPS, which is still smooth, but the Ultra preset’s 84.1 FPS is a more noticeable dip for those seeking maximum fidelity on a 4K display.

If the priority is absolute smoothness, Low settings at 1080p produce 250.5 FPS, but that leaves performance on the table given the RTX 5090’s capabilities. A more practical recommendation is Medium at 4K, which yields 168.2 FPS and keeps the frame rate above the 144 Hz threshold while offering better visuals than Low. The data shows that Ultra is only worth it at 1080p, where 179.9 FPS still feels responsive, but at higher resolutions the cost in frame rate outweighs the fidelity gain. For most users, High at 1440p or Medium at 4K provides the best measured balance between smoothness and image quality, with the former being the standout choice due to its high average FPS and moderate settings.

GPU Role

The NVIDIA GeForce RTX 5090 is a Blackwell 2.0 architecture GPU built on TSMC’s 5 nm process, with 92,200 million transistors on a 750 mm² die. It features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth, which is more than sufficient for Downfall’s horror environments. The GPU’s boost clock of 2407 MHz and base clock of 2017 MHz drive 21,760 shading units, and the benchmark results reflect its top-tier status: it scores 39,650 in Passmark G3D and 14411 in 3DMark Steel Nomad DX12, placing it in the 94th percentile of all GPUs. Its nearest rivals include the RTX 5090 D (0.1% ahead), RTX 5050 Mobile (0.2% ahead), and AMD Radeon PRO W6600 (1.3% ahead), showing that it sits at the very top of the performance stack.

In Downfall, the GPU’s massive memory pool and bandwidth are rarely stressed, as the game’s textures are from 2016 and do not require 32 GB of VRAM. The frame rate data shows that the GPU scales well with resolution, but the CPU bottleneck at lower resolutions prevents it from reaching its full potential. The RTX 5090’s pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s allow it to handle the game’s lighting and shadow effects easily, even at 4K Ultra where 84.1 FPS is still playable. The GPU’s role is to provide headroom, and the measured results show that it has plenty of it — the limiting factor in this pairing is almost always the processor, not the graphics card.

FAQ

CPU Role

The AMD Ryzen 5 2600 is a 2018-era six-core, 12-thread processor based on the Zen+ architecture, built on GlobalFoundries’ 12 nm process. It has a base clock of 3.40 GHz and a boost clock of 3.90 GHz, with 16 MB of shared L3 cache and dual-channel DDR4 memory support. Its benchmark scores are modest by modern standards: 1,127 in Cinebench R15 multi-core, 4,698 in R20 multi-core, and 11,186 in R23 multi-core. The single-core scores are 159 in R15, 663 in R20, and 1,579 in R23, which place it in the 77th percentile of all CPUs. Its nearest rivals include the Intel Core i5-1345U (0.4% ahead), AMD Ryzen 5 7530U (0.6% behind), Intel Core i5-11600KF (0.6% ahead), and Intel Core i7-10700F (0.7% behind), showing that it sits in a closely contested mid-range band.

In Downfall, the CPU’s role is to feed the RTX 5090 with draw calls and game logic, and the data shows it struggles to keep up at lower resolutions. At 1080p Low, the system achieves 250.5 FPS, but this is likely near the CPU’s practical limit for this game. The 12 threads are sufficient for the horror title’s single-threaded tendencies, but the 3.90 GHz boost clock is low compared to modern processors, which limits the maximum frame rate. The measured FPS gap between 1080p and 1440p at Low settings is only 9.9% (250.5 to 225.2 FPS), which is smaller than the 1440p-to-4K drop of 15.3% (225.2 to 190.7 FPS), indicating that the CPU is the bottleneck until the resolution increases enough to shift the load to the GPU.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low averages 250.5 FPS, Medium 232.2 FPS, High 214.9 FPS, and Ultra 179.9 FPS. The spread from Low to Ultra is 70.6 FPS, or 28.2% of the Low value, which is the smallest relative spread of any resolution. This compression is a sign of CPU limiting, as the GPU could easily render more frames if the CPU allowed it. At 2560x1440, the average FPS values are 225.2 (Low), 207.7 (Medium), 196.1 (High), and 136.3 (Ultra). The drop from High to Ultra is 59.8 FPS, or 30.5%, which is the steepest single-step penalty at this resolution, highlighting Ultra’s heavy GPU load. At 3840x2160, the averages fall to 190.7 (Low), 168.2 (Medium), 136.8 (High), and 84.1 (Ultra). The Ultra preset at 4K is the only measured row below 100 FPS, and the gap between Low and Ultra is 106.6 FPS, or 55.9%, showing that the GPU is fully engaged at this resolution.

Comparing settings across resolutions, Low shows the smallest absolute differences: 250.5 at 1080p, 225.2 at 1440p, and 190.7 at 4K. This suggests that Low is the most CPU-bound preset, since the frame rate drops more modestly as resolution increases. Ultra shows the largest absolute differences: 179.9 at 1080p, 136.3 at 1440p, and 84.1 at 4K, indicating that Ultra is the most GPU-bound preset. The data overall paints a picture of a system that can handle Downfall at any settings, but the Ryzen 5 2600 becomes the limiting factor at 1080p, while the RTX 5090’s immense power is only fully utilized at 4K Ultra, where it still delivers a playable 84.1 FPS.
