FSR

Yesterday I was playing POE as usual, then I closed the game and when I reopened the Upscale mode: FSR (Render Resolution: Best Performance) option was no longer available, that option was the one that let me play the game, my PC is somewhat old, but I could still do all the content, including ritual and delirium which are 2 mechanics that consume a lot but I could do them without problem, I have tried in several ways to reactivate it but I have not been able to. I would appreciate it if someone could help me solve this problem
