Doom

Best Settings per Resolution

At 1920x1080, the Intel Core i5-11400F and NVIDIA GeForce RTX 3080 combination delivers its maximum visual quality at Ultra settings with an average of 181 FPS. This is well above the 60 FPS playability threshold, and even the most demanding preset leaves substantial headroom for high-refresh-rate displays.

Moving to 2560x1440, the Ultra preset remains fully playable with an average of 117 FPS. The data shows that this resolution still allows the full range of settings without compromise, as the GPU has enough performance headroom to maintain fluid frame rates at the highest quality tier.

At 3840x2160, the Ultra preset still clears the 60 FPS threshold, averaging 63 FPS. This is the most demanding configuration tested, and it remains playable, though with far less margin than lower resolutions. For users who want additional safety margin at 4K, the High preset averages 78 FPS, while Medium averages 92 FPS and Low averages 105 FPS. The recorded data indicates that Ultra at 4K is the boundary case: it works, but it sits only 3 FPS above the playability threshold.

The verdict by resolution in the database confirms that all four settings tiers (Low, Medium, High, and Ultra) are playable at every resolution tested. The best settings per resolution are therefore Ultra at all three resolutions, with average frame rates of 181 FPS at 1080p, 117 FPS at 1440p, and 63 FPS at 4K.

CPU and GPU Roles

The scaling between resolutions reveals how the balance of CPU and GPU workload shifts as pixel count increases. At 1920x1080, the frame rates are extremely high across all settings: 301 FPS on Low, 262 FPS on Medium, 221 FPS on High, and 181 FPS on Ultra. These numbers are high enough that both the CPU and GPU are working near their limits, but the relatively modest drop from Low to Ultra (40% reduction) suggests that the GPU is becoming the primary constraint even at 1080p, since the i5-11400F is capable of feeding very high frame rates.

At 2560x1440, the same pattern continues with more GPU pressure. Low averages 195 FPS, Medium 170 FPS, High 143 FPS, and Ultra 117 FPS. The reduction from 1080p to 1440p at each setting is consistent: roughly 35% lower at Low, 35% lower at Medium, 35% lower at High, and 35% lower at Ultra. This uniform scaling across all settings points to the GPU as the dominant factor, as the CPU workload does not change with resolution.

At 3840x2160, the GPU becomes even more clearly the bottleneck. Low averages 105 FPS, Medium 92 FPS, High 78 FPS, and Ultra 63 FPS. The drop from 1440p to 4K is steeper: about 46% at Low, 46% at Medium, 45% at High, and 46% at Ultra. This consistent 45-46% reduction regardless of settings indicates that resolution scaling is almost entirely a GPU-bound phenomenon. The CPU's role remains constant because the game's CPU workload is tied to scene complexity and game logic, not to output resolution.

The data also shows that the gap between Low and Ultra narrows as resolution increases. At 1080p, Low to Ultra is a 120 FPS spread. At 1440p, the spread narrows to 78 FPS. At 4K, it narrows further to 42 FPS. This is the classic signature of GPU-bound scaling: at lower resolutions, the CPU can push higher frame rates, making the GPU settings matter more in absolute terms. At higher resolutions, the GPU is saturated even at Low settings, so raising settings costs relatively less frame rate.

The i5-11400F, with its 6 cores and 12 threads, is not the limiting factor in this pairing for Doom. The recorded benchmarks show the CPU sits at the 71st percentile among all CPUs, and its multi-threaded Cinebench R23 score of 14340 indicates ample headroom for a game from 2016. The RTX 3080, at the 68th percentile among GPUs, carries the scaling burden across resolutions.

FAQ

Q: Can this system run Doom at 4K with maximum settings?

A: Yes. At 3840x2160 with Ultra settings, the combination averages 63 FPS, which is above the 60 FPS playability threshold. The verdict by resolution lists Ultra as the best playable setting at 4K.

Q: What frame rate can I expect at 1440p on High settings?

A: The measured average is 143 FPS at 2560x1440 with High settings. This leaves considerable headroom above the 60 FPS threshold, and the Medium preset averages 170 FPS with a minimum of 144 FPS.

Q: Is the CPU or GPU more important for this game at 1080p?

A: The data indicates the GPU matters more even at 1080p. Frame rates scale consistently across resolutions, and the uniform reduction from 1080p to 1440p to 4K (roughly 35% and then 45-46%) points to GPU-bound operation at all tested resolutions.

Q: How much performance headroom exists at 1080p Ultra?

A: The average of 181 FPS at 1920x1080 Ultra is roughly three times the 60 FPS playability threshold. This makes the system suitable for high-refresh-rate monitors at 1080p.

Q: What is the lowest frame rate recorded for this combo?

A: The minimum recorded value appears only for Medium settings. At 3840x2160 Medium, the minimum is 78 FPS. At 2560x1440 Medium, the minimum is 144 FPS. At 1920x1080 Medium, the minimum is 223 FPS. All other settings list only average values.

Q: Does this system meet the 60 FPS requirement at every resolution and setting?

A: Yes. The database lists all four settings (Low, Medium, High, Ultra) as playable at every resolution tested. The lowest average is 63 FPS at 4K Ultra, which still exceeds the threshold.

Similar Performance Alternatives

The CPU's nearest rivals in the database provide context for how the i5-11400F compares. The AMD EPYC 7H12 scores 17120 on average, which is 0.3% lower than the i5-11400F's 17177 average benchmark score. The Intel Core i5-12450H scores 17239, 0.4% higher. The AMD Ryzen 3 PRO 8300G scores 17278, 0.6% higher. The Intel Core Ultra 7 164U scores 17074, 0.6% lower. In practical terms, any of these processors would deliver nearly identical performance in Doom, since the differences are all under 1%. The game is clearly not CPU-limited with this class of processor, so swapping to any of these rivals would produce no meaningful change in frame rates.

For the GPU, the nearest rivals show similar clustering. The NVIDIA P106-100 scores 23249 on average, 0.3% higher than the RTX 3080's 23172. The AMD Radeon Pro Vega 16 scores 23250, 0.3% higher. The AMD Radeon RX 6600M scores 23273, 0.4% higher. The AMD Radeon R9 M290X scores 23276, 0.4% higher. These four rivals bracket the RTX 3080 within a 0.4% band, meaning any of them would produce practically identical frame rates in Doom. The recorded data shows that the RTX 3080 sits at the 68th percentile among all GPUs, and these rivals occupy essentially the same performance tier.

The implication for users is that this exact combination is not unique in its performance envelope. A system built with the i5-11400F paired with any of the GPU rivals listed would behave nearly identically, and the same applies to swapping the CPU for any of its rivals while keeping the RTX 3080.

How This Combo Ranks

The database ranks this specific CPU-GPU combination at position 1054 out of 3712 tested combos for Doom. This places it in the upper 28th percentile of all tested systems. The rank reflects the overall capability of the pairing across the game's tested configurations.

The percentile positions of the individual components help explain this ranking. The i5-11400F sits at the 71st percentile among all CPUs, while the RTX 3080 sits at the 68th percentile among all GPUs. The combo rank of 1054 out of 3712 is consistent with what would be expected from these two components: solidly above average, but not in the top tier reserved for flagship CPUs paired with flagship GPUs.

For a game released in 2016, this ranking is more than sufficient. The combination outperforms the vast majority of tested systems, and the frame rate data confirms that it exceeds the 60 FPS playability threshold at every resolution and setting combination tested. The rank of 1054 out of 3712 means roughly 2,600 other combinations in the database are slower for this game, while about 1,050 are faster.

The Verdict

The recorded data answers the question directly: yes, the Intel Core i5-11400F with NVIDIA GeForce RTX 3080 can run Doom, and it does so with substantial margin. The verdict by resolution lists every settings tier as playable at every resolution.

At 1920x1080, the system achieves 181 FPS at Ultra settings, 221 FPS at High, 262 FPS at Medium, and 301 FPS at Low. All of these are far above the 60 FPS threshold. At 2560x1440, Ultra averages 117 FPS, High averages 143 FPS, Medium averages 170 FPS, and Low averages 195 FPS. Again, all clear the threshold with room to spare. At 3840x2160, Ultra averages 63 FPS, High averages 78 FPS, Medium averages 92 FPS, and Low averages 105 FPS. Even the most demanding 4K Ultra configuration stays above 60 FPS.

The conclusion is straightforward: this system runs Doom at maximum settings across all tested resolutions, including 4K. The only caveat is that 4K Ultra at 63 FPS provides less than 10% margin above the playability threshold, so users who prefer a larger safety buffer may choose High settings at 4K for 78 FPS. At 1080p and 1440p, there is no reason to lower settings unless targeting very high refresh rates.

Measured FPS Breakdown

The database contains measured average frame rates for three resolutions and four settings tiers each, for a total of 12 data points. Minimum and maximum values are recorded only for the Medium preset at each resolution.

At 1920x1080, the average frame rates are:

• Low: 301 FPS
• Medium: 262 FPS, with a minimum of 223 FPS and a maximum of 301 FPS
• High: 221 FPS
• Ultra: 181 FPS

At 2560x1440, the average frame rates are:

• Low: 195 FPS
• Medium: 170 FPS, with a minimum of 144 FPS and a maximum of 195 FPS
• High: 143 FPS
• Ultra: 117 FPS

At 3840x2160, the average frame rates are:

• Low: 105 FPS
• Medium: 92 FPS, with a minimum of 78 FPS and a maximum of 106 FPS
• High: 78 FPS
• Ultra: 63 FPS

The pattern across all resolutions is consistent: each step from Low to Medium to High to Ultra reduces average frame rates by roughly 10-15% per tier at 1080p, 12-16% at 1440p, and 12-18% at 4K. The Medium preset minimum values provide useful worst-case information: at 4K, the minimum of 78 FPS is still above the playability threshold, and at 1080p, the minimum of 223 FPS indicates very stable performance.

The frame rate deltas between resolutions at the same settings are also consistent. Going from 1080p to 1440p reduces frame rates by about 35% across all settings. Going from 1440p to 4K reduces frame rates by about 46% across all settings. This consistency confirms that the GPU is the limiting factor at every resolution tested, and that the CPU is not creating any resolution-dependent bottlenecks.
