Framepacing on PC has always been broken for me, the only way I've ever been able to get it to be smooth is using ifpsclamp in the ini file which ties the game speed to your refresh rate, that combined with 1/2 refresh rate and borderless mode. Problem with that method though is when you drop frames you get actual slowdown (the game will run in slomo), and there are game breaking bugs that you gotta work around with console commands when opening certain doors. All very annoying. This patch has fixed nothing sadly.
You can try rivatuner and other framerate limiting methods, but ultimately, I find those methods still have noticeable judder with camera movement, less noticeable if you're using a mouse. I thought maybe these issues along with the weapon debris setting on RTX cards might finally be addressed, especially since so many people are running high refresh rate monitors these days, but seems we're still stuck with a very stuttery 60fps limit.
