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 275 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 257 FPS. At 4K, all settings exceed 195 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce RTX 2070) for Counter-Strike 2. The Ryzen 5 8645HS is 28% above the recommended CPU (Core i7-9700K).
The Ryzen 5 8645HS determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 1080p low, the Ryzen 5 8645HS sets the ceiling at about 418 FPS, while the GeForce RTX 4090 could reach 700 FPS. In this scenario, the CPU limits the GPU potential by 40% (FPS gap: 282 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Ryzen 5 8645HS 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 40% | CPU Limits GPU 36% | CPU Limits GPU 39% | CPU Limits GPU 38% |
| 1440p (2K QHD) | CPU Limits GPU 37% | CPU Limits GPU 32% | CPU Limits GPU 34% | CPU Limits GPU 33% |
| 4K (Ultra HD) | CPU Limits GPU 30% | CPU Limits GPU 32% | CPU Limits GPU 31% | CPU Limits GPU 33% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Ryzen 5 8645HS + GeForce RTX 4090 pairing runs this title with CPU utilization between 28% and 84% and GPU utilization between 20% and 100%. Ryzen 5 8645HS stays in a controlled operating range, while GeForce RTX 4090 becomes the primary limiter at high visual load. As resolution scales, average GPU load rises from 34% at 1080p to 86% at 4K, while CPU averages move from 59% to 47%.
This profile is GPU-bound. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 93% usage (86-100%), while the Ryzen 5 8645HS stays at 44% (33-54%), indicating the graphics pipeline is the limiting stage.
At 1080p, averages sit around CPU 59% and GPU 34%. At 1440p, that shifts to CPU 46% and GPU 73%, and at 4K it reaches CPU 47% and GPU 86%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 48% (42-54%) and GPU 91% (84-98%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 5 8645HS remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 5 8645HS and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Ryzen 5 8645HS paired with the GeForce RTX 4090 can run Counter-Strike 2 smoothly up to 4k achieving around 195 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 28% above 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 Ryzen 5 8645HS 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 Ryzen 5 8645HS and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
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.
