How do I check if my GPU supports Raytracing?

Generally, all Nvidia cards, which have RTX in their name fully support raytracing. For AMD all cards of the new 6000 series support raytracing.

Since your gpu is a year or two old, you can ignore AMD here, as the cards, which support it were released at the end of 2020. However, it's quite possible you have a RTX card from Nvidias 2000 series.

Do note, that technically many other cards can support raytracing, but lack the dedicated raytracing cores. This means, they would work with raytracing, but the performance loss would be so gigantic, that the game should be nearly unplayable.
