Frequently Asked Questions
What CPU do I need for Killing Floor 3?
A Intel Core i5-13600KF-class processor meets the recommended bar. For high frame rates a Intel Core i7-8750H Processor gives more headroom. Verify any chip with our free Can I Run It checker.
Does the CPU matter for Killing Floor 3, 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 Killing Floor 3?
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.
