I had the same problem. I am playing on a Mac Pro 5,1 computer with Windows 11 Pro boot, Radeon RX 6800 GPU and Dell G3223Q gamers display. This machine behaves just like any ordinary PC. I do not have the R1 key that has been cited, above, as solution for this problem on Play Station, or the RB. It took me some time to discover that the key on PC is Q. I had been doing it wrong all along. Taking shelter makes gun fights much easier to survive. Important discovery.

I am 73 and having terrific fun with RDR2. Like you, my reaction times are not what they used to be, and occasionally my son will skillfully fight a battle for me if I have tried 3 times and died each time. But I have noticed that as I train up my dead eye, I get better and can usually survive the shoot-outs. I think we go a little slower than we would once have as teenagers, but we get there with persistence and patient skill acquisition. Don't give up.
