Frequently Asked Questions
What CPU do I need for S.T.A.L.K.E.R. 2: Heart of Chornobyl?
A Intel Core i5-6300U Processor-class processor meets the recommended bar. For high frame rates a Intel Core i5-13500 gives more headroom. For 1440p+ gaming while streaming, a Intel Core i7-13700KF or better is ideal. Verify any chip with our free Can I Run It checker.
Does the CPU matter for S.T.A.L.K.E.R. 2: Heart of Chornobyl, or just the GPU?
Gaming is GPU-bound, so the graphics card matters most for raw settings and resolution. But the CPU sets your frame-rate ceiling — it matters most at high refresh rates, at 1080p, and in CPU-heavy games (strategy, simulation, open-world). A weak CPU paired with a strong GPU causes a bottleneck.
Will my CPU bottleneck S.T.A.L.K.E.R. 2: Heart of Chornobyl?
It can, if your CPU is much weaker than your GPU. Check the exact balance of your build with our free bottleneck calculator before buying either component.
