GPU Role

The NVIDIA GeForce RTX 3080 Ti brings 12 GB of GDDR6X memory across a 384-bit bus, delivering 912.4 GB/s of bandwidth — a figure that proves critical in Doom's fast-paced texture streaming. The Ampere architecture chip runs at a base clock of 1365 MHz with a boost clock of 1665 MHz, while memory operates at an effective 19 Gbps. With 10,240 shading units, 320 TMUs, and 112 ROPs, the GPU's raw throughput is substantial: 34.10 TFLOPS of FP32 compute and a texture rate of 532.8 GTexel/s.

The measured frame rates reveal how the GPU's capabilities scale with settings. At 4K, the RTX 3080 Ti delivers 108.5 FPS on Low, 94.5 FPS on Medium, 83.5 FPS on High, and 65.6 FPS on Ultra — a spread of 42.9 FPS between the lowest and highest presets. This 65.4% performance delta between Low and Ultra at 4K indicates the GPU is being pushed hard at higher settings, with the 12 GB VRAM buffer handling the increased texture loads without apparent stuttering, as evidenced by the consistent average frame rates.

The GPU's benchmark profile shows a PassMark G3D score of 26,896 and a 3DMark Steel Nomad DX12 score of 5,077, with Vulkan performance at 171,798 in Geekbench. These scores place the card just 0.5% behind the RTX 3090 (41,441 vs. 41,224) and 1.1% behind the RTX 5070 (41,687 vs. 41,224) in average benchmark score, confirming that the RTX 3080 Ti remains a high-end performer in this title. The pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s are directly relevant to Doom's id Tech engine, which relies heavily on texture fill and pixel throughput for its environmental detail.

Resolution Scaling

The measured data shows a clear pattern of frame rate erosion as resolution increases, with the most dramatic drops occurring at the highest settings. At Ultra settings, the average FPS falls from 190.8 at 1080p to 122.8 at 1440p (a 35.6% reduction), then to 65.6 at 4K (another 46.6% drop from 1440p). This steep decline suggests the GPU is the primary bottleneck at Ultra, as the rendering load increases roughly proportionally with pixel count.

At Low settings, the scaling is more moderate: 315.4 FPS at 1080p drops to 205.7 FPS at 1440p (34.8% reduction), then to 108.5 FPS at 4K (47.3% reduction from 1440p). The fact that even Low settings show a significant 4K penalty indicates the RTX 3080 Ti is still being stressed at 4K regardless of quality preset. However, the absolute values remain high — 108.5 FPS at 4K Low is still very playable.

The intermediate presets show similar relative scaling. Medium settings deliver 274.8 FPS at 1080p, 178.6 FPS at 1440p, and 94.5 FPS at 4K. High settings produce 232.8 FPS at 1080p, 147.4 FPS at 1440p, and 83.5 FPS at 4K. Across all presets, the 1080p-to-1440p transition costs roughly 35-40% of performance, while the 1440p-to-4K transition costs another 44-48%. This consistent pattern indicates that the limiting component shifts from CPU-bound at 1080p to GPU-bound at 4K, with the Ryzen 7 9800X3D's strong single-thread performance (3,341 Geekbench single-core, 4,800 Cinebench R23 single-core) providing ample CPU headroom even at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the data shows a wide performance envelope across settings. Low settings produce the highest average at 315.4 FPS, followed by Medium at 274.8 FPS, High at 232.8 FPS, and Ultra at 190.8 FPS. The gap between Low and Ultra is 124.6 FPS, a 65.3% increase from the lowest to highest preset. These figures indicate that at 1080p, the CPU's 8 cores and 16 threads with 96 MB L3 cache are sufficient to feed the GPU even at the lowest settings, where the frame rate approaches the practical limits of the engine.

At 2560x1440, the same pattern holds but with lower absolute values. Low averages 205.7 FPS, Medium 178.6 FPS, High 147.4 FPS, and Ultra 122.8 FPS. The spread between Low and Ultra is 82.9 FPS, representing a 67.5% difference. Notably, the 1440p Ultra result of 122.8 FPS is still well above the 60 FPS threshold, and even the most demanding preset at this resolution maintains high fluidity.

At 3840x2160, the performance envelope narrows in relative terms but remains strong in absolute terms. Low averages 108.5 FPS, Medium 94.5 FPS, High 83.5 FPS, and Ultra 65.6 FPS. The Low-to-Ultra spread is 42.9 FPS, a 65.4% difference. The 4K Ultra result of 65.6 FPS is the only measured configuration that approaches the 60 FPS line, but it still clears it. This suggests that for 4K gaming, players should expect to use High or lower settings if they desire a larger frame rate buffer above 60 FPS.

Comparing across resolutions at the same settings, the scaling is consistent. At Ultra, 1080p to 1440p costs 68 FPS (190.8 to 122.8), and 1440p to 4K costs 57.2 FPS (122.8 to 65.6). At Low, the same transitions cost 109.7 FPS and 97.2 FPS respectively. The larger absolute drops at lower settings reflect the CPU's ability to push very high frame rates at 1080p, while the GPU becomes the limiting factor as pixel count increases.

Settings Recommendations

Based on the measured data, the optimal settings depend on the target resolution and desired frame rate headroom. For 1920x1080, even Ultra settings deliver 190.8 FPS, which exceeds the refresh rate of most high-end monitors. Players with 144 Hz or 240 Hz displays can comfortably use High (232.8 FPS) or Medium (274.8 FPS) to maximize visual quality while maintaining frame rates well above display refresh rates. The data shows no practical reason to drop below Medium at 1080p, as the visual quality difference between Medium and High is not justified by the 42 FPS difference when both are already above 230 FPS.

At 2560x1440, the recommendation shifts toward High as the sweet spot. High delivers 147.4 FPS, which is sufficient for 144 Hz displays with a small margin. Ultra at 122.8 FPS is also viable for 120 Hz panels, but the 24.6 FPS drop from High may not be worth the visual gain depending on panel refresh rate. For players prioritizing frame rate above all else, Medium at 178.6 FPS provides excellent headroom, while Low at 205.7 FPS is only advisable for competitive play where maximum responsiveness is desired.

At 3840x2160, the data indicates that High (83.5 FPS) is the highest preset that maintains a comfortable margin above 60 FPS. Ultra at 65.6 FPS is technically playable but leaves little headroom for demanding scenes. Medium at 94.5 FPS offers a better balance for 4K, providing a 44% improvement over Ultra while still delivering strong visual fidelity. Low at 108.5 FPS is the best choice for 4K gaming on high-refresh-rate displays, as it nearly doubles the Ultra frame rate while the visual differences at 4K are less perceptible due to the high pixel density.

Overall, the recommended configuration is High settings at 1080p or 1440p, and Medium or High at 4K depending on display refresh rate. The Ryzen 7 9800X3D's CPU performance ensures that frame rates are GPU-limited at 4K and CPU-sufficient at 1080p, making the RTX 3080 Ti the primary factor in settings selection. The data shows no configuration in the measured set falls below 60 FPS average, so players can prioritize visual quality with confidence that playability is maintained.
