Does DLSS Add Input Lag? What Actually Happens to Your Mouse
Super-resolution barely touches latency; frame generation is a different story. How to test both honestly in your own games.

Upscaling & Rendering Tech Explainers
Modern rendering menus are full of three-letter acronyms and philosophical questions: is ray tracing worth half your frame rate? Should motion blur stay on? These guides explain what each technology actually does, what it costs, and which trade-offs players tend to prefer – so you can decide with your own eyes instead of guessing.

Which Upscaler Fits Your Setup
The short version: pick the option your game actually offers and your graphics card actually supports. DLSS needs an RTX card, XeSS runs best on Arc hardware but has a fallback path elsewhere, and FSR runs almost anywhere because it does not depend on dedicated hardware. When a game offers more than one, the usual order of preference for image stability is DLSS, then XeSS, then FSR, but the gap narrows every generation and an older FSR build can beat a badly tuned DLSS one in a specific title.
The quality tier matters more than the logo. Moving from Quality to Balanced buys roughly 15 to 20 percent more frame rate and costs a little fine detail; moving to Performance is a bigger jump in both directions and starts to show on thin geometry such as fences, grass and distant cables. On a 1080p panel, Performance often looks soft because the internal resolution drops below 720p, while on a 4K panel the same tier still has plenty of pixels to work with.
Order of Operations
Change one layer at a time: first the base graphics preset, then the upscaler tier, then ray tracing if you want it, and only last the frame generation option. Doing it the other way round makes it impossible to tell which change caused a drop in image quality or responsiveness. Ray tracing is the most expensive single switch in most menus, and motion blur or depth of field should be judged after frame rate is stable, because they change how motion feels rather than how fast the game runs.
Scope of These Explainers
These pages describe what each in-game option does and which way a player might lean. They are preference guidance, not benchmarks, and they do not cover drivers, system files or fault finding.
Putting it into practice: see these technologies applied in per-game graphics presets, or dial in your monitor with Display & HDR guides.
