Game locked to 82 fps
I know it wasn't like when I booted it up a few weeks ago but is locked to 82 fps. GPU usage is at 44% and CPU is at 7%. Not locked in nvidia inspector, control panel or rivatuner. What else could it be?

Well it should be locked to 60 until the update hopefully fixes any high-fps issues for people with systems that can use it.

the game sets the max fps to half the monitors verticle hz since the engine as stated by its creator Bethesda bugs out over 60fps this means that monitors over 120hz run the game to fast as ipresentlevel in the ini file is set by the game to 1 for 60hz monitors or 2 for 120hz monitors to get the 60fps result the game requires.

here is Bethesdas statement on the subject THIS IS NOT from a trendie as one individual keeps spouting. Remember if we do not manually edit the ini file to change ipresentinterval it is either set to 1 for 60hz or less monitors or 2 for 120hz or higher monitors.

Ipresentinterval 0 ; to unlock the fps breaking the game unless its locked to 60fps by gpu software.

ipresentinterval 1 ; to set the fps to equal the monitor verticle hz

Ipresentinterval 2 ; to set the fps to half the monitor verticle hz.

As stated this setting is auto set by the game unless we manually change it in the ini files and if the game is not locked to 60fps script timing, physics, and a lot of other things will be messed up dialogue being out of sync is just one of the symptoms.

Bad or no setup, something has changed in your PC.

With a 144 hz monitor should I set ipresentinterval to 2 then cap the game at 72 fps? Was having crazy high GPU temps on ipi 1 fps uncapped, capped fps at 75 on ipi 1 which fixed GPU temps and now just having minor issues with timing and physics.

ipresentinterval has a 2 option????????????????????
as far i know it has only 0=off (what it shoud be normaly when you are cleaver and changed it to that) or 1=on (what means the games twisted sense of internal vsync and fps throttle to hold the engine alive is set in action. default after you installed the game or erased the config files)
what shoud 2 be? megaon?

for the inital qustion: even your 82 is boarderline to fast, the engine is trimmed to work with 60fps max, because ALL in the game is hooked to the fps

If the game is locked at 82 i am sure Op has a 240 Hz monitor that is set to 1/3 rd of it in his GPU settings. And he can change it htere.

I had for a short time a TUF Gaming laptop with 120 Hz monitor that insisted on capping the game at 40. Untill i figutred out the correct settings in my Nvidia Program tabs.

My current rig is a 144 Hz monitor and the default after install is 72 FPS. I have not had many issues with running at 72. Remember some freeze locks on entering PA out in terrain.

No matter what rig you have it is wise to manually set the FPS cap to 60, and this is done in your GPU Software menus.

based on the linked bethesda support page https://help.bethesda.net/#en/answer/31653 it has the 3 options 0, 1, 2 afterall in 2012 most monitors were either 60hz or 120hz and half of 120hz was 60 so thats how they set up the game when creating it.

of coarse the core of the engine was created over a decade before that for the earlier tes games they just kept expanding the script language (commands) and the graphics quality while keeping the physics and script timing tied to the framerate. Thus the issues when exceeding 60fps.

When I tested it unlocked (the zero setting uncapped) menu choices went past to fast to select I just bounced off terminals when trying to activate them the dialogue was way out of sync and the lockpick mini game was instantly breaking bobby pins with no chance of even opening anything.

As well as the slightest bump of a car was an instant explosion

165 hz monitor which is completely unlocked. I have many older titles that run at full 165. also have iPresentInterval=1 in the settings. I've had this issue with fallout 4 before I just can't remember how i fixed it.

I was able to fix the issue by unchecking the windowed mode and borderless boxes in the options menu. Game is fully unlocked at 165 and if I check those boxes again it goes back to 82.
