It may sound ridiculous, and not end up working for you, but if you already have the framerate cap set to "Max," have you tried going into the graphics options, and hitting the "apply" button again while in-game? Sometimes it can "unstick" the framerate; the in-game frame cap really is very broken.
Also, if you haven't already, you can also try experimental again, as they updated it (again) since they rolled it into the live branch.
I have not tried those yet but since I was just in game when I saw this, I went ahead and changed it, applied, changed back to Max, hit apply and quit out for a moment. For now I've also removed any visual mods (regrettably) until the devs optimize the base game better.
So, having tried the new experimental, a few things stood out on changes. When doing a scan, things like Heridium pylons or other elements you can mine that have the green boxes around them when scanned, will stand out for a much longer period of time and further away. I noticed also that if I watch the scan as it spreads outward, it will highlight those same things that are underground for a moment (Pretty sure it didn't do the underground part before). Example below, forgot to screenshot the underground look.
Also, they definitely resolved the blurry texture look. I think the internal rendering now matches the resolution you set it to. I removed the mod that lets you set the internal resolution (used the default 1.00) and I see no difference in visual quality. I'm pretty sure they also toned down the massive DOF.
The blueprints bug may have been fixed. I know for a fact the +3 Stamina Boost was bugged for me and a Korvax just gave it to me and I wasn't told I already had it and it's in my blueprints now!
There is a new minor bug now. Whenever I enter a doorway, it's almost like the character is having to walk over something right on the open doorway. When trying to exit, it will not go over the invisible box and a quick tap of the jetpack while moving forward gets me out the doors now.
Other minor things I noticed is in the anti-aliasing options, it now says Ultra before SSAA 4x. When I was adjusting the Max FPS, I saw 90 and 110 as an option. Not sure if that was there before but I thought it was just 30/60/Max before.
Thus far after removing the visual mods, I'm more consistently getting around 60fps but still get the occasional drops to 20-30fps but it's happening far less. I think this is due to the internal resolution and DOF smearfest being fixed. Still needs a lot of optimization but it's progress.
