It plays like an epic western. The controls aren't unlike GTA. I found them confusing but that's possibly because I was dipping in and out rather than playing it solid.
It'll definitely squeeze your 1060.
Don't you DARE blame yourself for the absolutely god-awful controls in that game. It's not your fault. It's not anybody's fault but Rockstar's.
I'm probably 15 hours deep into the game (not playing anything else) and the controls are still often opaque to me. Like, I was just knocking out the gunslingers quests, and I'm still not 100% sure how I'm supposed to duel. Then there are the times when bandits roll up on me and I cannot figure out how I'm supposed to draw my gun and shoot them. Or there's the inevitable time when you'll punch your horse.
And that's before we get to the hidden/forgotten mechanics, like eagle eye. They teach you about that shit once VERY early in the game. Then you kinda forget about it, and just kinda blindly fumble about the world looking for items and especially herbs. Then many, many hours in you realize that this shit is a million times easier if you just use eagle eye. But, like, why hadn't you at least accidentally stumbled upon it in your prior 10+ hours playing the game? Oh, it's because you invoke it using the "completely natural" press-both-sticks input. :-| (I realize this is maybe less obscure on PC KMB.)
And EVEN THAT is before we talk about the absolutely atrocious early-game checkpointing. The missions where you have to talk to five people, then hop on horses, ride for a few minutes, get off and do some spying for a couple minutes, then ride down and fight. But, what if you fuck up BECAUSE THE CONTROLS ARE TERRIBLE? Well, you have to do all of the dialogue, riding, spying all over again! It made me want to smash my everything. And this happens in multiple missions, one of which midway through you're looking for a female companion which went into a building with two doors. If you choose the wrong door, and it's locked, and you assume maybe you need to peek around back because maybe she was abducted and they locked the door, you end up out-of-bounds and you fail the missing and have to do ~10 minutes of the mission leading up to that all over again.
[The weirdest thing about that though, is that later in the game it probably has the most friendly checkpointing system of all time. Not only is the checkpointing very generous, but if you fail a certain leg three times it gives you the option to simply skip that part. It's very good.]
But aside from all that, the game is amazing. Wonderful characters, moments, world-building, etc. Really fantastic, and completely worth working your way through the control/checkpointing issues.
