Counter-Strike 2

Counter-Strike 2 with an Intel Core i5-10400F and NVIDIA GeForce RTX 5090 is a study in extreme imbalance. The data shows a 6-core Comet Lake CPU from 2020 paired with a flagship Blackwell GPU from 2025, resulting in frame rates that range from playable to absurdly high depending on the settings and resolution. This combination ranks in the 90th percentile out of 1632 tested combos, indicating that despite the CPU's age, the overall experience is exceptional, though the bottleneck is clearly defined by the processor.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a classic CPU-bound scenario at lower resolutions, with the GPU taking over as the primary limiter only at 4K. At 1080p with Low settings, the combo produces 510.9 FPS. Moving to 1440p Low drops that to 443.3 FPS, a 13.2% reduction. However, jumping to 4K Low yields 288.7 FPS, a 34.9% drop from 1440p. This pattern indicates that at 1080p and 1440p, the i5-10400F is the limiting factor; the RTX 5090 is being held back by the CPU's single-thread performance. The data shows the CPU scores 688 in 3dmark_single_thread, which is modest, and while it boosts to 4.30 GHz, it cannot feed the GPU enough frames at lower resolutions.

At 4K, the pendulum swings. The gap between Low and Ultra settings at 4K is substantial: 288.7 FPS versus 140.1 FPS, a 51.5% performance hit. This shows that at 4K, the GPU's workload becomes significant enough to matter. The RTX 5090's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are not strained by Counter-Strike 2, but the sheer pixel throughput at 3840x2160 starts to engage the GPU's shading units (21760) and ROPs (176). The result is that while 1080p and 1440p performance is largely flat due to the CPU, 4K performance scales more predictably with settings, indicating a shift toward GPU limitation. For players with high-refresh-rate 1080p or 1440p monitors, the CPU will cap the experience; for 4K displays, the GPU becomes the arbiter of frame rates.

FAQ

Q: Is the Intel Core i5-10400F a bottleneck for the RTX 5090 in Counter-Strike 2?

A: Yes, the data strongly suggests this. At 1080p Low, the combo hits 510.9 FPS, but this is likely the CPU's ceiling. The CPU's single-thread score of 688 and 6 cores (12 threads) limit how fast it can process game logic and draw calls, preventing the RTX 5090 from reaching even higher frame rates that the GPU could theoretically produce.

Q: What is the best resolution for this combo to maximize frame rates?

A: The lowest resolution tested, 1920x1080, yields the highest average FPS. With Low settings at 1080p, the combo achieves 510.9 FPS. However, the difference between 1080p and 1440p is relatively small, with 1440p Low producing 443.3 FPS, suggesting that 1440p is the sweet spot for balancing visual clarity and high refresh rates without a massive FPS penalty.

Q: How does the Ultra preset compare to Low in terms of performance drop?

A: The penalty is steep. At 1080p, Ultra produces 374.9 FPS versus 510.9 FPS on Low, a 26.6% reduction. At 4K, the drop is more severe: 140.1 FPS on Ultra versus 288.7 FPS on Low, a 51.5% reduction. The Ultra preset appears to be particularly demanding, likely due to advanced shadow and particle effects that tax the GPU.

Q: Does the RTX 5090's massive VRAM capacity matter for this game?

A: Not in any practical sense. Counter-Strike 2 is not a VRAM-heavy title, and the 32 GB GDDR7 buffer is vastly overprovisioned. The data shows no indication of memory-related stutters or limitations. The GPU's performance is instead dictated by its raw compute, such as the 104.8 TFLOPS FP32 throughput.

Q: Is this combo overkill for competitive play?

A: For competitive play, yes. Achieving over 400 FPS on Medium settings at 1440p (416 FPS) far exceeds the refresh rate of most monitors. The data shows that even the most demanding preset at 1080p (Ultra, 374.9 FPS) is well above 240Hz, making this setup more about future-proofing or pushing high refresh rates at 4K than practical necessity.

Q: How does the CPU's performance compare to its rivals in synthetic benchmarks?

A: The i5-10400F's average benchmark score is 14168, placing it 0.4% above the AMD EPYC 7552 and 1.1% below the Intel Core i5-8500. Its percentile rank of 73 versus all CPUs shows it is a mid-range performer, but its 6 cores and 4.30 GHz boost clock are sufficient for the high frame rates seen in the measured FPS data.

CPU Role

The Intel Core i5-10400F is the anchor of this pairing, and its age shows in the results. With 6 cores and 12 threads, it relies on a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The benchmark data shows a single-thread score of 688 in 3dmark, which is the critical metric for Counter-Strike 2, a game that is notoriously sensitive to single-core performance. The CPU's passmark_single_thread score of 2541 and cinebench_r23_singlecore score of 1453 corroborate this. While these scores are respectable for a 2020 processor, they are not elite by 2025 standards.

The measured FPS data reveals the CPU's impact. At 1080p, the performance ceiling is evident: Low settings yield 510.9 FPS, but High settings still produce 426.6 FPS, and Ultra drops to 374.9 FPS. The spread between Low and Ultra at 1080p is 136 FPS, which is surprisingly large for a CPU-bound scenario. This suggests that while the CPU is the primary limiter, the settings do influence the CPU's workload through physics and AI calculations. The 12 MB of shared L3 cache is a modest amount, but it appears sufficient for this engine. The CPU's rank in this game is 90th percentile out of 1632 combos, indicating that despite its limitations, it pairs well enough to deliver top-tier results. However, the data implies that a newer CPU with higher single-thread performance would unlock even higher frame rates, particularly at 1080p.

Measured FPS Breakdown

The data provides a clear matrix of performance across three resolutions and four settings presets. Starting at 1920x1080, the combo delivers exceptional numbers. Low settings produce 510.9 FPS, Medium 475.4 FPS, High 426.6 FPS, and Ultra 374.9 FPS. The transition from Low to Ultra costs 136 FPS, a 26.6% drop. At 2560x1440, the numbers remain high but show more variability. Low achieves 443.3 FPS, Medium 416 FPS, High 316.8 FPS, and Ultra 245.7 FPS. The drop from Low to Ultra at 1440p is 197.6 FPS, a 44.6% reduction. Finally, at 3840x2160, the performance falls significantly. Low produces 288.7 FPS, Medium 237.7 FPS, High 176.1 FPS, and Ultra 140.1 FPS. The Ultra preset at 4K is the lowest result in the entire dataset, representing a 51.5% drop from Low.

These numbers tell a story of diminishing returns. At 1080p, even the Ultra preset is above 360 FPS, which is overkill for most displays. At 1440p, Medium is the only preset that breaks 400 FPS, while High and Ultra remain above 240 FPS. At 4K, only Low and Medium exceed 200 FPS, and High and Ultra dip below 180 FPS. The data shows that the RTX 5090 is powerful enough to handle Counter-Strike 2 at any setting, but the CPU limits the absolute maximum frame rates. For players targeting 360Hz monitors, 1080p Low or Medium is the only viable path. For 240Hz monitors, 1440p Medium or High works well. For 4K 120Hz displays, Low or Medium settings are required to maintain a stable frame rate above 120 FPS.

GPU Role

The NVIDIA GeForce RTX 5090 is an unmitigated powerhouse, but its role in this pairing is often constrained by the CPU. With 21760 shading units and a boost clock of 2407 MHz, the GPU is capable of massive compute throughput, as evidenced by its 104.8 TFLOPS FP32 rating. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is the highest in the dataset. However, in Counter-Strike 2, the GPU's high-end specs are only fully utilized at 4K resolution.

The measured FPS data shows that the GPU's performance scales with resolution. At 4K, the difference between Low and Ultra settings is 148.6 FPS, which indicates that the GPU is actively rendering more complex scenes. The GPU's passmark_g3d score of 39650 and percentile rank of 94 versus all GPUs confirm its top-tier status. Interestingly, its nearest rival, the NVIDIA GeForce RTX 5090 D, is only 0.1% faster in average benchmark score (84241 vs 84306), showing that this particular variant is already at the peak of the product stack. The GPU's 176 ROPs and 680 TMUs handle texture and pixel throughput efficiently, but the game is not demanding enough to stress these components at lower resolutions. At 1080p and 1440p, the GPU is effectively waiting for the CPU to deliver draw calls, resulting in the CPU-bound behavior observed. Only at 4K does the GPU's workload become substantial enough to influence the frame rate, as seen in the sharper drop-off between settings at that resolution.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend entirely on the display's refresh rate and resolution. For 1080p displays with refresh rates up to 240Hz, the Medium preset is the best choice, delivering 475.4 FPS. This provides a comfortable margin above 240Hz while offering better visual fidelity than Low. The High preset at 426.6 FPS is also viable for 240Hz panels, but Medium offers a higher safety margin.

For 1440p displays, the situation is more nuanced. For 240Hz monitors, the Medium preset at 416 FPS is the only option that clears the 400 FPS threshold, making it the recommended choice. For 165Hz monitors, the High preset at 316.8 FPS is ideal, as it provides a significant visual upgrade over Medium while still being well above the refresh rate. The Ultra preset at 245.7 FPS is also usable for 240Hz displays, but it leaves little headroom, so Medium or High is safer for maintaining consistent frame times.

For 4K displays, the recommendations shift to prioritize the GPU. For 144Hz panels, the Medium preset at 237.7 FPS is the best option, as it delivers high visual quality without dropping below the refresh rate. The High preset at 176.1 FPS is suitable for 120Hz displays, offering a better balance of visuals and performance. The Ultra preset at 140.1 FPS is only recommended for 60Hz displays, as it provides the best image quality but cannot sustain high refresh rates. Across all resolutions, the Low preset is generally unnecessary unless targeting extreme frame rates for competitive play, but it does provide the highest possible FPS at 1080p (510.9 FPS) and 1440p (443.3 FPS). The data suggests that Medium is the "sweet spot" for this combo, offering a 43% performance increase over Ultra at 4K while maintaining good visual fidelity.
