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, performance runs at around 56 FPS. At 1440p, performance is around 56 FPS. At 4K, frame rates range from 41 to 56 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for PUBG: BATTLEGROUNDS. The Core i5-2520M is 52% below minimum CPU requirement.
The Core i5-2520M 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 i5-2520M sets the ceiling at about 56 FPS, while the GeForce RTX 4090 could reach 417 FPS. In this scenario, the CPU limits the GPU potential by 87% (FPS gap: 361 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i5-2520M 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 87% | CPU Limits GPU 85% | CPU Limits GPU 80% | CPU Limits GPU 79% |
| 1440p (2K QHD) | CPU Limits GPU 83% | CPU Limits GPU 82% | CPU Limits GPU 76% | CPU Limits GPU 75% |
| 4K (Ultra HD) | CPU Limits GPU 78% | CPU Limits GPU 77% | CPU Limits GPU 69% | CPU Limits GPU 73% |
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 i5-2520M + GeForce RTX 4090 pairing runs this title with CPU utilization between 54% and 90% and GPU utilization between 40% and 94%. Core i5-2520M reaches high load in heavier scenarios, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 65% at 1080p to 78% at 4K, while CPU averages move from 68% to 68%.
From a utilization perspective, this is a CPU-heavy load profile. At 4K (Ultra HD) Low, the Core i5-2520M reaches 88% average load (85-90%), while the GeForce RTX 4090 remains comparatively lower at 57% (45-69%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 68% and GPU 65%. At 1440p, that shifts to CPU 68% and GPU 80%, and at 4K it reaches CPU 68% and GPU 78%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 60% (54-67%) and GPU 88% (83-93%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-2520M remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i5-2520M 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.

The Core i5-2520M and GeForce RTX 4090 will struggle to run PUBG: BATTLEGROUNDS at smooth framerates. At 1080p Ultra, you can expect around 56 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
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 i5-2520M 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 hardware falls below the minimum requirements for this game, which may result in poor 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.
