DLSS vs FSR vs XeSS
Upscaling technologies render from a lower internal resolution and reconstruct the image, trading some image characteristics for higher performance.
Key things to check
- Quality modes preserve more detail
- Benefits grow when GPU-limited
- Support varies by game and GPU
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.
