Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 5 5600X and NVIDIA GeForce RTX 3070 Ti reveals a clear and consistent pattern: performance scales almost linearly with resolution, but the magnitude of the drop varies significantly by settings preset. At 1920x1080 with Low settings, the combination delivers 273.6 FPS average. Moving to 2560x1440 Low drops that to 175 FPS, a reduction of approximately 36%. At 3840x2160 Low, the average falls to 95.2 FPS, which is another 46% reduction from the 1440p figure. This steep decline indicates that even at Low settings, the GPU is the dominant limiting factor as pixel count rises.

The scaling behavior under Ultra settings tells a slightly different story. At 1080p Ultra, the system produces 163.5 FPS average. At 1440p Ultra, that number drops to 107.8 FPS, a 34% decrease. At 4K Ultra, the average falls to 59.4 FPS, another 45% drop from 1440p. The fact that the percentage losses are nearly identical across Low and Ultra presets suggests that the rendering workload scales uniformly with resolution, and the RTX 3070 Ti is consistently the bottleneck regardless of how much graphical detail is enabled.

The gap between Low and Ultra at each resolution also quantifies the GPU headroom. At 1080p, Low produces 273.6 FPS while Ultra produces 163.5 FPS — a difference of 110.1 FPS, or roughly 67% more performance from dropping to Low. At 4K, Low produces 95.2 FPS while Ultra produces 59.4 FPS, a difference of 35.8 FPS. The absolute delta shrinks at higher resolutions because the GPU is already saturated, but the relative penalty of Ultra remains substantial. This indicates that Doom's Ultra preset imposes a heavy shading and texture load that the 8 GB frame buffer and 608.3 GB/s memory bandwidth of the RTX 3070 Ti must absorb.

The data also shows that 1440p is the sweet spot for high refresh rate displays. At High settings, 1440p yields 129.5 FPS, which comfortably exceeds 120 Hz. At 1080p High, the system hits 199.2 FPS, which is above most 144 Hz panels but below the ceiling of 240 Hz monitors. At 4K, even Low settings only reach 95.2 FPS, so 60 Hz displays are the practical target at that resolution. The scaling pattern confirms that the CPU — a 6-core, 12-thread Zen 3 part with a 4.60 GHz boost clock — is not the limiting factor here; the consistent resolution-driven declines point squarely at the GPU.

Q: Does the RTX 3070 Ti's position relative to its rivals change at different resolutions?

A: The measured data does not include rival GPU framerates, but the GPU's average benchmark score of 30849 places it 0.3% ahead of the AMD Radeon RX 590 GME and 0.8% behind the AMD Radeon RX 6700. This relative standing is consistent across all tested resolutions since the bottleneck remains the GPU.

Q: Is the Ryzen 5 5600X holding back the RTX 3070 Ti in this game?

A: The data does not show CPU bottleneck symptoms. At 1080p Low, the system reaches 273.6 FPS, and at 1440p Low it hits 175 FPS. The consistent resolution scaling, with no plateau at lower resolutions, indicates the GPU is the primary limiter even at high framerates.

Settings Recommendations

The measured FPS rows provide a clear hierarchy for optimizing the experience in Doom. For users targeting 60 FPS at 4K, the High preset at 71.3 FPS average offers the best visual quality while maintaining a safe margin above the 60 FPS threshold. The Ultra preset at 4K drops to 59.4 FPS, which is technically playable but leaves no headroom for demanding scenes. Medium at 4K provides 86.1 FPS, but the jump to High is only a 17% performance cost for presumably better visual fidelity, making High the recommended 4K preset.

At 1440p, the situation favors higher presets. High settings deliver 129.5 FPS, which is sufficient for 120 Hz displays. Ultra at 1440p produces 107.8 FPS, still well above 100 FPS and suitable for high refresh rate gaming. The delta between Medium (153.1 FPS) and High (129.5 FPS) is 23.6 FPS, but the visual improvement from Medium to High is typically more noticeable than from High to Ultra. For most 1440p users, High offers the best balance, with Ultra as a viable option for those with 100 Hz or lower refresh rate panels.

At 1080p, the system is capable of extremely high framerates. Low settings hit 273.6 FPS, Medium hits 239.9 FPS, High hits 199.2 FPS, and Ultra hits 163.5 FPS. For competitive play, Medium at 239.9 FPS is the recommended choice — it stays above 240 Hz thresholds while offering better visuals than Low. High at 199.2 FPS is the best choice for users with 144 Hz or 165 Hz monitors, as it provides a comfortable margin above those refresh rates. Ultra at 163.5 FPS is only recommended for users with 160 Hz or lower displays who prioritize image quality above all else.

The data indicates that the "best experience" depends heavily on display refresh rate. At 4K, High is the only preset that both exceeds 60 FPS and offers substantial visual quality. At 1440p, High is the sweet spot for 120 Hz, while Ultra is acceptable for 100 Hz. At 1080p, Medium maximizes framerate for 240 Hz panels, and High is ideal for 144-165 Hz panels. The measured rows show that the RTX 3070 Ti has enough headroom at 1080p to run any preset at framerates above 160 FPS, so the choice there is purely about refresh rate matching.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest framerates across all presets. Low settings produce an average of 273.6 FPS, the single highest measured value in the data set. Medium settings reduce this to 239.9 FPS, a drop of 33.7 FPS. High settings yield 199.2 FPS, another 40.7 FPS reduction. Ultra settings produce 163.5 FPS, which is 35.7 FPS below High. The full spread from Low to Ultra at 1080p is 110.1 FPS, indicating that the GPU can absorb significant settings changes at this resolution without falling below playable framerates.

At 2560x1440, the framerates remain high but show more sensitivity to settings. Low settings average 175 FPS, which is a 98.6 FPS drop from 1080p Low. Medium settings reach 153.1 FPS, a 21.9 FPS drop from Low at the same resolution. High settings produce 129.5 FPS, a 23.6 FPS drop from Medium. Ultra settings average 107.8 FPS, a 21.7 FPS drop from High. The spread from Low to Ultra at 1440p is 67.2 FPS, which is narrower than at 1080p but still substantial. All presets at 1440p remain above 100 FPS, which is notable for a 4K-capable card.

At 3840x2160, the system moves into more demanding territory. Low settings average 95.2 FPS, which is the only 4K preset that comfortably exceeds 90 FPS. Medium settings drop to 86.1 FPS, a 9.1 FPS reduction. High settings fall to 71.3 FPS, a 14.8 FPS drop from Medium. Ultra settings produce 59.4 FPS, the lowest measured value in the entire data set, and a further 11.9 FPS drop from High. The spread from Low to Ultra at 4K is 35.8 FPS, which is the smallest absolute spread across all resolutions. This compression suggests that at 4K, the GPU is fully utilized even at Low settings, and the incremental cost of each preset is smaller in absolute terms.

Across all resolutions, the relative cost of each preset is consistent. Moving from Low to Medium costs roughly 12-13% of performance at each resolution. Moving from Medium to High costs about 17% at 1080p and 1440p, but 21% at 4K. Moving from High to Ultra costs about 18% at 1080p, 17% at 1440p, and 20% at 4K. The data shows that the RTX 3070 Ti handles 1080p and 1440p with ease, while 4K requires careful preset selection to stay above 60 FPS.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is the dominant component in determining Doom's performance across all measured configurations. The GPU's specifications — 8 GB of GDDR6X memory on a 256-bit bus with 608.3 GB/s bandwidth, a base clock of 1575 MHz, and a boost clock of 1770 MHz — are directly relevant to the resolution scaling observed in the data. At 4K, the 8 GB frame buffer is likely a limiting factor for Ultra settings, which may explain the steep drop to 59.4 FPS. The 608.3 GB/s bandwidth, while substantial, is finite, and the 4K Ultra preset appears to push the memory subsystem to its limits.

The GPU's compute capabilities also align with the framerate results. The RTX 3070 Ti features 6144 shading units, 192 texture mapping units, and 96 ROPs, with a pixel rate of 169.9 GPixel/s and a texture rate of 339.8 GTexel/s. These specifications translate into a measured PassMark G3D score of 23356 and a Geekbench Vulkan score of 130778. The 21.75 TFLOPS of FP32 performance is consistent with the high framerates observed at 1080p and 1440p, where the GPU is not fully saturated and can deliver 199.2 FPS at High settings.

The GPU's position among its rivals, as measured by average benchmark scores, further contextualizes the Doom results. With an average benchmark score of 30849, the RTX 3070 Ti sits 0.3% ahead of the AMD Radeon RX 590 GME and 0.9% ahead of the NVIDIA Quadro M5000. It trails the AMD Radeon RX 6700 by 0.8% and the NVIDIA GRID M60-1Q by 1.2%. These small deltas indicate that the RTX 3070 Ti is closely matched with its immediate competitors, and in Doom specifically, the measured FPS data shows no signs of the GPU being an outlier in either direction. The percentile rank of 74 for all GPUs suggests that this card performs in the upper quartile, which is consistent with the high framerates observed even at 4K.

The GPU's memory clock of 1188 MHz, effective 19 Gbps, combined with the 256-bit bus, produces the 608.3 GB/s bandwidth figure. This bandwidth is critical at 4K, where texture streaming and frame buffer writes consume significant memory throughput. The measured FPS data shows that at 4K Ultra, the system drops to 59.4 FPS, which is likely a combination of compute load and memory bandwidth saturation. At 4K Low, the 95.2 FPS result indicates that reducing texture quality and shading complexity alleviates memory pressure, allowing the GPU to maintain higher throughput.

The GPU is also the component that defines the system's 4K viability. The CPU, with its 6 cores and 12 threads, is more than sufficient for Doom's engine, as evidenced by the 273.6 FPS result at 1080p Low. The fact that the framerate scales consistently with resolution and settings — rather than plateauing at a CPU-bound ceiling — confirms that the RTX 3070 Ti is the primary determinant of performance in this game. The 8 GB memory size is adequate for 1080p and 1440p at all presets, but the 4K Ultra result of 59.4 FPS suggests that the card is at the edge of its capability at that resolution and preset combination.
