The transition from Global Offensive to Counter-Strike 2 marked the end of the DX9 era for Valve. The new Source 2 engine introduces physically based rendering and dynamic smoke that interacts with lighting, significantly changing the performance profile. While CS:GO was light on the GPU, CS2 requires a competent card to handle these effects without stuttering. It remains CPU-heavy at competitive settings, where the 'sub-tick' server architecture demands strong single-thread performance. CPUs with large L3 caches, like AMD's X3D line, offer a major advantage. 8GB of RAM is now the absolute minimum, though more is recommended to avoid hitches.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 84 FPS. At 1440p, all settings exceed 69 FPS. At 4K, frame rates range from 46 to 95 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce RTX 2070) for Counter-Strike 2. The Pentium Gold G6405 is 78% below recommended, but 50% above minimum.
The Pentium Gold G6405 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 Pentium Gold G6405 sets the ceiling at about 95 FPS, while the GeForce RTX 4090 could reach 700 FPS. In this scenario, the CPU limits the GPU potential by 86% (FPS gap: 605 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Pentium Gold G6405 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 86% | CPU Limits GPU 84% | CPU Limits GPU 80% | CPU Limits GPU 81% |
| 1440p (2K QHD) | CPU Limits GPU 85% | CPU Limits GPU 82% | CPU Limits GPU 81% | CPU Limits GPU 82% |
| 4K (Ultra HD) | CPU Limits GPU 78% | CPU Limits GPU 83% | CPU Limits GPU 83% | CPU Limits GPU 84% |
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.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 78% below recommended and your GPU is 136% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

Yes, the Pentium Gold G6405 paired with the GeForce RTX 4090 can run Counter-Strike 2 smoothly up to 1440p achieving around 69 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 78% 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 Counter-Strike 2, upgrading the CPU would have the biggest impact on performance. The Pentium Gold G6405 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.
Counter-Strike 2 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.
Counter-Strike 2 requires at minimum a Core i5 750 (CPU) and GeForce GTX 660 (GPU) with 8 GB RAM and 85 GB storage. For the recommended experience, you need a Core i7-9700K and GeForce RTX 2070 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 Counter-Strike 2 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.
