Can your PC run S.T.A.L.K.E.R. 2: Heart of Chornobyl? The current official guide maps four hardware tiers to targets from 1080p at 30 FPS through 2160p at 60+ FPS. For the clearest starting point, GSC’s High (Recommended) tier targets 1440p at 60 FPS and calls for 32 GB of dual-channel DDR4 plus a Radeon RX 6800 XT, GeForce RTX 3070 Ti, or GeForce RTX 4070. These are official target configurations, not guarantees for every scene or PC. Independent GPU figures below are from launch-era tests in November 2024, not measurements of the current game build.
Official S.T.A.L.K.E.R. 2 PC requirements by resolution and target
GSC’s support guide, updated August 3, 2026, presents these specifications as configurations for different desired experiences. All four tiers list Windows 10/11 and a 160 GB SSD. The guide says its Low-tier evaluation used TSR and comparable technologies; for High, it lists TSR, DLSS, FSR, and XeSS as test technologies. The targets should not be read as native-resolution results or a promise that every listed component will produce the same frame rate in every situation.
| Tier | Resolution and target | CPU | Memory | GPU examples | Storage |
|---|---|---|---|---|---|
| Low | 1080p, 30 FPS | AMD Ryzen 5 1600X or Intel Core i7-7700K | 16 GB DDR4, dual channel | AMD Radeon RX 580 8 GB, NVIDIA GeForce GTX 1060 6 GB, or Intel Arc A750 | 160 GB SSD |
| Medium | 1080p, 60 FPS | AMD Ryzen 7 3700X or Intel Core i7-9700K | 16 GB DDR4, dual channel; 32 GB recommended for extra headroom | AMD Radeon RX 5700 XT, NVIDIA GeForce RTX 2070 SUPER, or GeForce RTX 4060 | 160 GB SSD |
| High (Recommended) | 1440p, 60 FPS | AMD Ryzen 7 3700X or Intel Core i7-9700K | 32 GB DDR4, dual channel | AMD Radeon RX 6800 XT, NVIDIA GeForce RTX 3070 Ti, or GeForce RTX 4070 | 160 GB SSD |
| Epic | 2160p, 60+ FPS | AMD Ryzen 7 7700X or Intel Core i7-13700KF | 32 GB | AMD Radeon RX 7900 XTX or NVIDIA GeForce RTX 4080 | 160 GB SSD |

What GPU do you need for S.T.A.L.K.E.R. 2?
Start with the resolution and preset you actually intend to use, then compare your whole PC with the corresponding official tier. For a 1440p, 60-FPS target at High, the guide names the RX 6800 XT, RTX 3070 Ti, and RTX 4070, alongside a matching CPU and 32 GB dual-channel memory. For 2160p and 60+ FPS at Epic, it names the RX 7900 XTX or RTX 4080 and a Ryzen 7 7700X or Core i7-13700KF.
#1 Best Overall
- Powered by Radeon RX 9070 XT
- WINDFORCE Cooling System
- Hawk Fan
- Server-grade Thermal Conductive Gel
- RGB Lighting
Those model lists are practical reference points, not a complete ranking of every GPU or a guarantee for a particular combination of settings. Upscaling, frame generation, driver versions, game build, CPU limits, and scene complexity all affect comparisons. A model name alone cannot answer how a different PC will perform.
VRAM can constrain higher presets
GSC’s optimization guidance says higher texture quality needs more VRAM and recommends lowering texture quality if available VRAM is running low. In TechSpot’s launch-era testing, VRAM use at 1440p High regularly exceeded 8 GB and sometimes rose above 9 GB. That observation describes TechSpot’s tested build and conditions; it is not a measurement or guarantee for the current build. The 8 GB and 16 GB RTX 4060 Ti variants also behaved differently in that test: TechSpot reported that the 16 GB model could make 1440p Epic with upscaling feasible, while the 8 GB version struggled and required moving to High.
How many FPS will you get?
The official tiers give target configurations, while third-party benchmark results describe only the specific builds, hardware, routes, and settings used in those tests. TechSpot said it tested 31 GPUs at three resolutions and three quality presets, following the day-one patch. In that launch-era test, it reported about 44 FPS for the Radeon RX 6600 at 1080p Medium without upscaling. Treat that as a result from TechSpot’s 2024 test, not a prediction for a current patch or your system.

Tom’s Hardware’s launch-era testing used a manual run through Zalissya, a village with NPCs, buildings, and trees. The publication ran each GPU at each setting at least twice, using the higher score; its first result for each preset involved three runs with the first discarded. In its 1080p Medium tests, high-end GPUs clustered around 100–105 FPS, which Tom’s Hardware attributed to CPU bottlenecks in that test setup. That range belongs to its route, hardware, settings, and November 2024 game build, not a general cap or current-build benchmark.

The two publications used different test methods, and results can shift when the game build, driver, route, upscaling, or frame-generation settings change. Tom’s Hardware also notes that rendering distance and level of detail can affect CPU load, so a test conducted at unusually low visual settings may not represent performance in a visually demanding game.
What to check when comparing benchmark results
A useful comparison should make its conditions visible. Check for:

- Powered by the NVIDIA Blackwell architecture and DLSS 4. System Requirements: Minimum 850W PSU with 16-pin 12V-2x6 (12VHPWR) connector required. Verify before purchasing.
- Military-grade components deliver rock-solid power and longer lifespan for ultimate durability. Compatibility: 348mm (13.7") length, 3.6 slots, 4.3 lbs. Confirm case clearance and slot spacing. GPU bracket included.
- Protective PCB coating helps protect against short circuits caused by moisture, dust, or debris
- 3.6-slot design with massive fin array optimized for airflow from three Axial-tech fans
- Phase-change GPU thermal pad helps ensure optimal thermal performance and longevity, outlasting traditional thermal paste for graphics cards under heavy loads
- Game patch or build and graphics-driver version.
- GPU model and VRAM, plus CPU, platform, and system memory.
- Resolution and preset, and whether rendering is native or upscaled.
- Upscaling mode and whether frame generation is enabled.
- Scene or route, number of runs, and whether the first run was discarded.
- Average FPS alongside low-percentile FPS or frame-time behavior.
- Image quality, since a higher displayed FPS may involve different rendering settings.
If a report omits these details, its FPS figure may not be comparable with another result or representative of your own setup.

GSC’s optimization article, dated September 1, 2026, recommends checking the system requirements, updating graphics drivers and Windows, and adjusting settings. It does not attach a specific FPS gain to any individual change, so treat these as troubleshooting steps rather than quantified fixes.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitches- Check the baseline: compare your CPU, GPU, memory, operating system, and SSD with the official tier closest to your target. See GSC’s requirements guide.
- Update software: install current graphics drivers and Windows updates, following GSC’s optimization guidance.
- Reduce settings that may be costly: test a lower texture quality if VRAM is tight; shadows may reduce performance, and GSC suggests changing anti-aliasing and effects to see whether performance improves.
- Check system configuration: close unnecessary background processes, try Windows Game Mode, review the power plan, and confirm that the monitor is plugged into the dedicated graphics card rather than a motherboard display output.
- Change one setting at a time: record FPS and frame-time behavior before and after each adjustment. This makes it easier to identify a useful change without confusing its effect with several simultaneous tweaks.
How to use these requirements for a buying or upgrade decision
Choose a target tier first; then compare the CPU, GPU, memory, and storage together. If you are aiming for 1440p High, the official GPU examples are relevant, but the listed 32 GB dual-channel memory and CPU class are part of that target too. If your current PC is close to a tier, settings such as texture quality, shadows, anti-aliasing, effects, and upscaling may change the experience, but the available evidence does not establish exact current-build FPS for every near-match.
For any purchase decision based on a specific FPS goal, look for a reproducible test on the same current game build and driver, with similar CPU, memory, resolution, preset, upscaling, and frame-generation settings. A launch-era chart can help explain hardware behavior, but it should not be treated as a current performance guarantee.
