A graphics card starts to feel old after 5–6 years, primarily because it starts to let you down in the latest games. The kind of performance you were used to starts becoming a memory, and you’re forced to compromise on the graphics settings to extend your GPU’s lifespan. That said, raw performance is just one way your GPU feels outdated. Depending on its age, it probably has way bigger limitations than sub-60 FPS. The factors that make your old GPU “too old” come down to its architecture, hardware limitations, software limitations, and memory. Weak performance isn’t the end of the world; you can tweak in-game sliders to get playable framerates. However, some bottlenecks you just can’t get rid of, and those are the ones that make your graphics card truly ancient.
