Is this game running at 30 FPS and would that cause eye strain/migraine? [I don't play consoles]

[TransgressorOfTheUnspeakableWord]

I saw mention of the v-sync of this game capping it at 30 FPS and suggestion that the player may want to consider disabling it in-game and, instead, enabling it for a specific 3D profile under their graphics card control panel.
Now, I figured this was simply about uncapping for a smoother experience.
I played this for the first time last night and it seemed smooth enough, although a bit weird and I had to shake my head a couple of times and readjust my vision. I put this down to me being unfamiliar the over-the-shoulder 3rd person view and also using a controller [the game won't rebind for a lefty, so I had to use a joystick - which I only really use with 8 bit console/arcade emulation]
The reason I'm querying this is because I don't game on more modern consoles and am not used to the fixed 30 FPS a few use. I know nothing about the subject but, as I woke up with bad eyes this morning [something that never happens] I wondered if the frame rate may have caused it.
I want to play again today, but not without adjustment if what I've supposed here is really a thing.
I see people talking about nausea from head-bob in games, and epileptic reactions to certain strobe frequencies, but I don't suffer from anything like that. In fact, I don't suffer anything - not even colds - so if any slight discomfort presents it's remarkable and I want to know what may have caused it. It's just my way. TIA.

Edit: Thinking on it, despite not owning consoles, I've played all sorts of low+/fixed frame rates in my life, so maybe it could instead be solely to the camera zooming in and out a lot. I'm thinking that's more likely; simply the fact I'm not used to the mechanic. What do any of you think?

I guess framerate *could* cause strain if it's low enough and/or locked at values that don't sit well with your monitor's refresh rate (like, I don't know, odd numbers like 43 fps), but if 30 is half the refresh rate, and it's stable, it should be fine... or at least it is most of the times; of course the higher it is the better for your eyes, so just get rid of that v-sync and let your gpu handle it.

From how I see it though, being unfamiliar with the OTS camera movement like you said is a much more likely cause... but who knows for sure.

V-Sync off and play with more than 100fps

[TransgressorOfTheUnspeakableWord]

It's a habit of mine to always enable v-sync. I hate tearing and would rather have a fixed forced lower frame rate.

The frame rate stuff is difficult to surmise because I personally don't know 'what' has the authority to take control of 'what'. Meaning, I don't know if games can override the system wide refresh rate or whether can only attempt to equally space frames of lower rates in with refreshes. I use old TTFL monitors and they max at 75Hz. Before you mentioned, I would assume the game would consult the monitor with an algorithm for the best fit. Ie: I assumed it would switch my monitor to 60Hz if it wanted to exact 30FPS at 1 frame per two screen cycles. If, however, it doesn't, then 75Hz->30FPS is gonna cause some additional pulsing

Anyway, enough about all that. For now I'll go with my addendum and your partial endorsement and see how I go. Even if it genuinely is at 30FPS it seems smooth to me.

highly inadvisable, the game gets glitchy at high framerates; don't know the exact numbers, but it's probably better to stick to something close to 60

On Linux, v-sync is working just like it should be.
It is tied to monitors refresh rate.

The ingame Vsync is bugged, disable it.
Then force Vsync externally with Nvidia Control Center.
Works fine, game runs at 60 FPS with no problem like that.
Dead Space 2 has the same problem.

DONT unlock the framerate over 60, there are multiple physic puzzles in the game that does not work and glitch out if your FPS are over 60.

The issue with this game's vsync implementation isn't just about how much more smooth it could be if it ran at 60fps over 30fps. That's irrefutable. This game's vsync implementation also causes significant input lag. It likely buffers a lot of extra frames because this is a console port, and their hardware at the time was really weak. That'd probably lead to frame time inconsistency and a really choppy experience. To achieve a smoother experience, they'd buffer as many frames as they could.

I have an AMD card. I run Dead Space 1-3 with Radeon Chill w FPS capped 80-140, enhanced sync, and FreeSync. It's a very smooth experience with no noticeable input lag. I've played all three games for 40+ hours apiece and have never noticed any physics issues beyond the occasional twitchy corpse.

As I previously stated, the game seemed to play fine for me also.

I played through the entire game at 144 fps with gsync on and vsync off. Just the one door at the beginning of the game I needed vsync on to get past it then everything was just fine.
