Fivem

Fivem, the long-running multiplayer modification framework built on Grand Theft Auto V, remains a demanding and idiosyncratic title in 2026. The measured data for the Intel Core Ultra X9 388H paired with the NVIDIA GeForce RTX 5080 reveals a system that scales predictably with resolution but exhibits a distinct sensitivity to preset selection. This combination, ranked 775th out of 3005 tested combos, places it firmly in the upper tier of configurations, though the raw numbers show that even flagship hardware must make concessions in this specific multiplayer environment.

Resolution Scaling

The progression from 1920x1080 to 3840x2160 demonstrates a classic GPU-bound curve, but the rate of decline is steeper than what typical AAA titles show. At High settings, the average frame rate drops from 162 FPS at 1080p to 107 FPS at 1440p, a 34% reduction, before falling further to 59 FPS at 4K, a 64% total loss from the 1080p baseline. This scaling pattern suggests that while the RTX 5080 is the primary limiting factor at higher resolutions, the CPU still has significant headroom to feed frames at 1080p, where the 162 FPS average is likely constrained by Fivem's inherent server-side and scripting overhead rather than pure rendering throughput.

The Low preset tells a similar story with amplified numbers. At 1920x1080, the combo delivers 256 FPS, which drops to 169 FPS at 2560x1440 and 94 FPS at 3840x2160. The 4K figure represents a 63% decrease from 1080p, nearly identical to the High preset's scaling. This consistency across presets indicates that resolution scaling is not dramatically affected by the quality settings themselves; the GPU is being taxed proportionally regardless of whether it is rendering simple or complex shaders. The gap between Low and High at each resolution narrows as pixel count rises, suggesting the RTX 5080's raw fillrate and bandwidth become the dominant constraint at 4K, whereas at 1080p the delta between presets is more pronounced.

Ultra settings exhibit the most aggressive scaling drop. The 126 FPS at 1080p falls to 83 FPS at 1440p, a 34% reduction, and then to 46 FPS at 4K, a 63% total decline. The Ultra preset at 4K is the only configuration that dips below the 60 FPS threshold, hitting an average of 46 FPS. This indicates that the combination of maximum quality effects and 4K resolution overwhelms even the 56.28 TFLOPS FP32 compute and 960.0 GB/s memory bandwidth of the RTX 5080. The data suggests that for a locked 60 FPS experience at 4K, users must drop to High settings, which delivers 59 FPS on average, or accept Medium's 74 FPS with its measured minimum of 63 FPS.

Settings Recommendations

The measured rows provide a clear hierarchy of playability. At 1920x1080, every preset is viable for high-refresh-rate monitors, with Low pushing 256 FPS and High still achieving 162 FPS. For competitive multiplayer scenarios where frame latency matters more than visual fidelity, the Low preset's 256 FPS average offers the maximum responsiveness, while Medium's 202 FPS with a minimum of 172 FPS provides a substantial safety margin against drops. Ultra at 126 FPS remains smooth but sacrifices nearly half the frame rate of Low for marginal visual gains that are often imperceptible in fast-paced gameplay.

At 2560x1440, the recommendation shifts toward Medium as the sweet spot. The 133 FPS average with a 113 FPS minimum ensures consistent smoothness on 144Hz displays, while High's 107 FPS average is still acceptable but leaves less headroom for the frame-time spikes common in multiplayer scenarios with many players and vehicles. Low at 169 FPS is the choice for esports-oriented play, but the visual downgrade in draw distance can be a tactical disadvantage in Fivem's open-world roleplay servers. Ultra at 83 FPS is usable but sits below the 144Hz refresh rate target, making it a poor trade-off unless visual quality is paramount.

For 3840x2160, the data strongly recommends Medium as the best experience. The 74 FPS average with a 63 FPS minimum stays above the 60 FPS v-sync threshold, providing a stable gameplay experience without the settings-induced stutter of High's 59 FPS average. Low at 94 FPS is the performance pick but sacrifices too much visual detail for a game that emphasizes environmental immersion. Ultra at 46 FPS is not recommended for any scenario, as the sub-60 FPS average will introduce noticeable judder on standard 60Hz displays. The measured data shows that Medium at 4K offers the best balance of visual fidelity and frame rate consistency for this hardware combination.

How This Combo Ranks

With a rank of 775 out of 3005 tested combinations, this pairing sits in the 74th percentile of all CPU-GPU combos tested in Fivem. This places it in the upper quartile but notably below the top-tier configurations that likely pair the RTX 5080 with flagship desktop CPUs. The Intel Core Ultra X9 388H, despite being a mobile processor with a 25W TDP, holds its own in this context, but the ranking suggests that Fivem's CPU-bound nature at lower resolutions prevents the RTX 5080 from fully flexing its capabilities.

The CPU's benchmark scores contextualize its contribution. The Cinebench R23 multicore score of 18911 and single-core score of 2200.5 place it at the 88th percentile among all CPUs, with nearest rivals including the AMD Ryzen 5 7500X3D (deltaPct -0.2), Intel Core i9-13950HX (deltaPct 0.3), AMD Ryzen AI Max 385 (deltaPct 0.4), and Intel Core i5-13600 (deltaPct 0.5). This clustering indicates that the Ultra X9 388H is competitive with mainstream desktop processors despite its mobile pedigree, which is crucial for Fivem's single-threaded scripting performance. The PassMark single-thread score of 4280 and multithread score of 36811 reinforce this positioning.

The GPU's percentile rank of 87 places it just below the CPU, with nearest rivals including the AMD Radeon 8060S (deltaPct 0.6), AMD Radeon RX 6750 GRE 12 GB (deltaPct 0.7), AMD Radeon Pro W5700X (deltaPct 2.3), and AMD Radeon RX 9070 GRE (deltaPct -2.2). This suggests the RTX 5080 is performing slightly below its expected aggregate benchmark positioning in Fivem, likely due to the game's engine limitations and multiplayer overhead rather than any hardware deficiency. The combo rank of 775 out of 3005 indicates that roughly 2230 tested combinations perform worse, but also that this configuration is not maximizing its potential in this specific title.

Measured FPS Breakdown

At 1920x1080, the full preset ladder shows a clear progression. Low leads with an average of 256 FPS, followed by Medium at 202 FPS with a minimum of 172 FPS and maximum of 233 FPS. High trails at 162 FPS, while Ultra bottoms out at 126 FPS. The delta between Low and Ultra is 130 FPS, representing a 51% performance penalty for maximum quality settings. This wide spread indicates that Fivem's visual settings have a substantial impact on rendering load, even at a resolution where the GPU is not the primary bottleneck.

The 2560x1440 results compress the range. Low delivers 169 FPS, Medium 133 FPS with a minimum of 113 FPS and maximum of 153 FPS, High 107 FPS, and Ultra 83 FPS. The gap between Low and Ultra narrows to 86 FPS, or 51% of the Low value, which is proportionally similar to the 1080p results. The Medium preset's minimum of 113 FPS is particularly notable as it remains above the 100 FPS threshold, suggesting this is a stable configuration for high-refresh-rate gaming at this resolution.

At 3840x2160, the numbers compress further. Low averages 94 FPS, Medium 74 FPS with a minimum of 63 FPS and maximum of 85 FPS, High 59 FPS, and Ultra 46 FPS. The Medium preset's 63 FPS minimum is the only 4K configuration that guarantees a 60 FPS floor, making it the only viable choice for consistent smoothness. High's 59 FPS average will result in periodic drops below 60 FPS, while Ultra's 46 FPS average is clearly unplayable for most users. The scaling from Low to Ultra at 4K shows a 48 FPS difference, or 51% of the Low value, maintaining the same proportional penalty seen at lower resolutions.

GPU Role

The RTX 5080's 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is sufficient for Fivem's texture streaming at all tested presets and resolutions. The measured data shows no evidence of memory capacity being a limiting factor, as even the Ultra preset at 4K, which would typically stress VRAM with high-resolution textures, still posts a playable 46 FPS average. The 16 GB capacity appears adequate for this game's asset sizes, which are inherited from Grand Theft Auto V's 2013-era design but augmented by player-created content.

The GPU's clock behavior, with a base of 2295 MHz and boost of 2617 MHz, supports the observed frame rates. The 56.28 TFLOPS FP32 compute is the theoretical peak, but Fivem's DirectX 11-era rendering pipeline does not fully utilize modern GPU features. The measured performance at 4K High (59 FPS) suggests the card is being pushed to its limits by the game's inefficient draw calls and lack of modern rendering techniques. The GPU's PassMark G3D score of 36565 and 3DMark Steel Nomad DX12 score of 8637 indicate strong synthetic performance, but Fivem's real-world results are lower than what these benchmarks would predict, highlighting the game's engine limitations.

The RTX 5080's 336 TMUs and 112 ROPs provide a 879.3 GTexel/s texture rate and 293.1 GPixel/s pixel rate, which are ample for this workload. The 84 RT cores and 336 tensor cores are largely idle in Fivem, as the game does not utilize ray tracing or DLSS features in the measured configurations. This means the GPU is performing pure rasterization work, where the 10752 shading units are the primary computational resource. The data shows that the RTX 5080 is not thermally or power constrained in this scenario, as the 360W TDP and 750W suggested PSU provide sufficient headroom for sustained boost clocks.
