G-Sync, FreeSync and VRR explained
Variable refresh rate lets the monitor adapt refresh timing to the GPU's frame delivery, reducing tearing and improving smoothness within the supported range.
Key things to check
- Enable VRR in driver/display settings
- Check supported range
- FPS caps can be useful in some setups
Why it matters for gaming
PC performance is the result of several components working together. Frame rate, frame-time consistency, loading, temperatures and upgrade compatibility can all be affected by the surrounding system. Use this guide as a starting point, then verify the specifications for your exact hardware.
Before you buy or change anything
Check the exact model numbers in your PC, read the motherboard and component documentation, and pay attention to FrameForecast compatibility warnings. A faster component is only a useful upgrade when the platform can safely support it and it improves the workload you actually care about.
