Skyrim PC First Person Stutter and Mouse Lag Fix

[ricfitzpatric]

Hey.

Have been playing Skyrim some odd 45 hours now and have been forced to rely on a third person viewpoint. I found the first person mode to constantly jar,skip and lag.

I changed the ini files for the mouse acceleration to 0 and turned off V sync but still encountered a hitchy play experiance when using first person.

I ended up changing the Uexteriorcell buffer from 36 to 72 in the Skyrim steam folder ini and in the document My games Skyrim ini. I pretty much have no stutter or lag in first person mode and it works silky smooth. This might be the fix to all the first person problems plaguing the pc version hopefully :thumbsup:

Can other pc players confirm this please?

Negative Ghost Rider didn’t fix anything. I am going to reset the variable to compare in order to see if it improved at all. If it does I will post back here if not I will not post again.

You said "changed the ini files for the mouse acceleration to 0 and turned off V sync " did you have those things enabled still when you changed the uexteriorcell variable or did you reset everything back to normal first?

What video settings did you have Skyrim at as well.

Interesting that the lag is only in first I had not noticed before that if I change to third it goes away.

I am genuinely interested if this works, and would also like to know if it messes with your saves or not, the same way adding "uCellsToLoad=9" will totally mess your save up. I experience butter smooth gameplay in Third-Person and even though 80-90% smooth in First-Person, I will get the occasional lag jump which is worse in certain areas for reasons I cannot figure out. Some exterior areas you'd think would be very laggy are quite nice, others I get it every 5-10 seconds. Interiors are typically very smooth, while certain ones like inns full of many NPCs I get horrible jittery lag in First-Person (But perfectly smooth in Third-Person).

 

For all reasons I cannot find an inextricable link between this and my FPS. FPS does not drop when this happens. Usually between 25-40 for me.

 

Does changing

uExterior Cell Buffer=36

to

uExterior Cell Buffer=72

really help with this? Please confirm.

 

EDIT::

 

After messing with it a while, I ended up disabling AA/AF completely as well as tweaking these settings:

 

In your SkyrimPrefs.ini change:

fLeafAnimDampenDistEnd=500.0000
fLeafAnimDampenDistStart=250.0000

 

These are the values I'm currently using and seem to do quite well. Lowering these will change the proximity bubble that trees will begin animating. I find that the vanilla settings are ridiculously large and will kill FPS in certain areas for users with low-end GPUs.

 

I've managed to get rid of my First-Person lag except once and a great while, which is quite alright. Anyone experiencing this problem should try these tips. Disable your AA/AF and reduce those values in your SkyrimPrefs.ini. I still do not know if the first tip given by the OP is worth while and whether it messes with your saves or not, so beware. Always make backups of your ini files before editing, and create new saves and test the performance thoroughly before proceeding, lest you enjoy losing a save or two.

 

Cheers

Having the same issue. I get about 20 fps in first person view regardless of stuff the game has to process. In third person view I get 50-60 fps outdoors and 70-100 indoors. Changing graphics settings between low and ultra changes the fps by one or two in first person view so its definitely a bug. None of op's tips helped. I'd rather not disable my AA/AF as my PC has the power to run the game with a solid 60 fps with ultra and I want to make use of it. Hoping to get this bug fixed.
