What causes stuttering when you have great FPS and no lag?

[FiftyTifty]

"Skyrim4GB no longer hooks GetTickCount()"

Well, that's what the change log says.

hrm last I looked in the code it still did... oh right it hooks GetProcAddress or something now. Seriously I don't look at it unless I have to. :D

Bit late on the uptake, but there is this ol' doohickey called the 64Hz bug. Y'see, what Bethesda decided to do in the subsequent revisions to their renderer post Morrowind, was implement the usage of GetTickCount().

Ever wondered why some games look smooth @ 30 fps, and others choppy? The choppy games, chances are, are using GetTickCount() in their renderer.

There are two ways to fix this for Oblivion/Fallout 3/Fallout New Vegas. #1 Is to cap your framerate to the minimum you experienced during play, and set iFPSClamp=##, with ## being your minimum framerate. This also works with Skyrim. Fallout 3 and New Vegas have bugs with the player model when using this ini edit.

Option #2 is to use Stutter Remover and enable the setting that is along the lines of bReplaceGetTickCount(). This is the best option. This will only work for Oblivion/Fallout 3/Fallout New Vegas, as only those three games have an SR mod for 'em.

Okay, thanks. I just did #2. I'll let ya know how it goes

Well MajinCry I tried your method and it seemed to slightly boost performance and lessen CTD but I was still CTD.

So what I did now is just tweak the multithreading options in ini...

Open up the fallout.ini file in: My Documents\My Games\Fallout3 (or Fallout NV, apparently)

Find the line:

bUseThreadedAI=0

change it to:

bUseThreadedAI=1

Add another line after it and insert:

iNumHWThreads=2

... And So far (last hour) I have not had CTD and have great performance

Oh and by the way the only thing that previously helped me with the stuttering problem, and other problems I was having in TTW (such as freezing seemingly forever in dad's office in DC when you choose traits) was to uninstall all big mods, all extra mods, and all mods that do too much shit. I narrowed it down to Project Nevada causing the problem, but then again I might have been doing something wrong in terms of the data files or setup/load order etc.

Cheers, I'll be back to report on if things get messed up or stay swell
