PUBG has improved significantly since its early access days but remains a demanding title. Large maps require aggressive asset streaming, making it sensitive to RAM and storage speed. 16GB of RAM is practically mandatory; with only 8GB, you will likely experience stuttering. An SSD is also crucial to ensure textures and buildings load in on time.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 155 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 147 FPS. At 4K, all settings exceed 77 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for PUBG: BATTLEGROUNDS. The Core i7-8665U is 49% below recommended, but 33% above minimum.
The Core i7-8665U sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Core i7-8665U sets the ceiling at about 155 FPS, while the GeForce RTX 4090 could reach 430 FPS. In this scenario, the CPU limits the GPU potential by 64% (FPS gap: 275 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i7-8665U is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 64% | CPU Limits GPU 58% | CPU Limits GPU 45% | CPU Limits GPU 41% |
| 1440p (2K QHD) | CPU Limits GPU 55% | CPU Limits GPU 51% | CPU Limits GPU 35% | CPU Limits GPU 37% |
| 4K (Ultra HD) | CPU Limits GPU 52% | CPU Limits GPU 57% | CPU Limits GPU 48% | CPU Limits GPU 51% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Core i7-8665U + GeForce RTX 4090 pairing runs this title with CPU utilization between 38% and 88% and GPU utilization between 63% and 100%. Core i7-8665U stays in a controlled operating range, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 78% at 1080p to 91% at 4K, while CPU averages move from 59% to 60%.
From a utilization perspective, this is a GPU-heavy load profile. At 1440p (2K QHD) Ultra, the GeForce RTX 4090 averages 96% usage (93-100%), while the Core i7-8665U stays at 52% (39-66%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 59% and GPU 78%. At 1440p, that shifts to CPU 60% and GPU 92%, and at 4K it reaches CPU 60% and GPU 91%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 54% (39-69%) and GPU 94% (89-100%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i7-8665U remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i7-8665U and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Core i7-8665U paired with the GeForce RTX 4090 can run PUBG: BATTLEGROUNDS smoothly up to 4k achieving around 77 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 49% below the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For PUBG: BATTLEGROUNDS, upgrading the CPU would have the biggest impact on performance. The Core i7-8665U is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
PUBG: BATTLEGROUNDS does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
PUBG: BATTLEGROUNDS requires at minimum a Core i5-4430 (CPU) and GeForce GTX 960 (GPU) with 8 GB RAM and 40 GB storage. For the recommended experience, you need a Core i5-6600K and GeForce GTX 1060 with 16 GB RAM. Your setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
These PUBG: BATTLEGROUNDS FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
