With the FPS limit imposed, the FPS counter fluctuated between 47 and 48.
Ok, I just got a limit of 45 to run smoothly but it stops after a while and becomes choppy again. It seems like capping the framerate is more like a suggestion to the graphic's engine and not a hard limit, and once it deviates too far the camera refresh rate becomes halved again and stays halved. That's my theory at least, because I just can't get consistent results even after trying a range of values from 44 to 48.
Having the camera running at 40 fps consistently seems like the next best thing so I might leave my framerate completely uncapped, my FPS seems to hover around 120 if I do that.
Hmm, it's a shame these framerate limiters are so inconsistent. I guess some internal timer might be out of sync with the game, or imprecise, or... something like that... ¯\_(ツ)_/¯
Some possible alternatives for framerate limiting:
• You could try creating a custom resolution through Nvidia Control Panel, e.g. 1440x1080, 16-bit colour, set to run at 47Hz or 40Hz, and enable V-sync on that. Might be tricky to get the game running at the right refresh rate if the resolution already exists, so if that occurs you could try making a unique resolution like 1440x1079 (with only the 47Hz refresh rate available)
• Run FRAPS while playing, set video capture to 47 or 40fps, half-size, no audio, lock framerate while recording, then press and hold the record hotkey until the framerate counter turns pink (should lock to the specified FPS). Requires a bit of free hard-drive space (determined by loop buffer length), may be a bit jittery on slower HDDs. Might not be advisable to use on an SSD due to repeated writes. Other recording software might have similar options, could perform better.
It is really strange that the framerate would work this way, how the heck did you figure this out in the first place??
Originally I was just trying to find a framerate where the weapon animations looked normal. I have a 120Hz monitor, so the camera running at ~40fps normally didn't seem too choppy to me (compared to how I expected the 30fps cap I'd seen mentioned
The first thing I tried was enabling half refresh rate adaptive V-sync through Nvidia Control Panel, which made the weapon animations look a bit closer to normal but made the camera movement feel pretty bad. The animations were still a bit fast (comparing the timing of the right-click lightsaber swings vs. when they actually hit), so I decided to try 1/3rd refresh rate V-sync. That improved the animations even more, and bizarrely made the camera movement much smoother than half refresh V-sync. Once I noticed this I decided to look at other caps to find the highest framerate I could use with both smooth camera motion and normal animation speeds - I switched to using RTSS for framerate limiting and tried a cap of 50fps (awful), 49 (slightly better), 48, 47...
tl;dr: fiddling around and trial and error
