I thought this was a joke thread at first. I've been browsing through the GTAV input lag thread off and on and I thought this was a response to that.
But wow, this patch is amazing. Early Christmas gift for sure.
I only had some time to experiment before work, but FPV feels really sharp, almost as good as a dedicated FPS now. I turned auto aim off completely, killed the dead zone and worked with the acceleration until drawing a bead on something felt instinctive.
Third person feels really good too. Before the patch, I hadn't played GTAV for a couple of weeks. I've been playing Ground Zeroes and when I went back to GTAV this morning without messing with the new settings, it was awful. After tweaking things a bit and killing the deadzone, it felt awesome to be able to track cars as they drive.
There's still a slight input delay that makes things feel a bit heavier than a dedicated TPS or FPS, but overall this is a night and day improvement. I almost want to start the story over again and play with the new settings.
