Stutterring but reads 60fps

A shot in the dark. Is it a Pixel-Art Game and has low resolution with pixel rounding enabled? Then try try disable pixel rounding.

Unfortunately no, it's a side scroller with hi res graphics.

I'd also like to say that I've been working on the project for over a year now and this issue is so serious that I'll need to switch engines if I can't resolve it. Something I really don't want to do.

I've been happily and confidently going by (the 60 fps) )readings on the fps counter until now and even decided to update the minimum device specs to something more modern to overcome the fps issues I previously was encountering, but for the kind of work I'm just now doing on the project, the janking issues are so glaringly obvious, its just not feasible to release in this kind of state.

If the scirra team can offer any advice that would be great :)

Got a minimal example project or video? It would be useful to troubleshoot your issue, or for the devs to look into. I've seen jank and jitter mean different things to different people.

For example, your sprites could be jittering back and forth position wise at 60 fps if there is a positioning issue such as the previously mentioned pixel rounding. It can happen when your camera and object are moving at the same speed but with slightly offset timing. There can also be pinning issues if you're using a pinned camera where the camera position updates one tick later. This can happen no matter how high your fps is.

One time in discord someone was complaining about their game recordings showing "jank" when running at 60 fps, but it was because their videos were recorded at 19fps or something silly like that.

It's highly likely your stuttering/jank/jitter has nothing to do with fps at all.

That's not really true:

Not sure if you really forget on purpose or ????

as on the videos, they clearly showed you the settings before recording at 60 FPS please do not invent false accusations.

Yes, It was one of the tests at 19FPS trying different crazy configurations as they told you just for testing but all the rest of the videos were at 60PFS as they show you clearly on that video.

I never saw this follow up video at 60 fps, just the one you posted at low fps. I have no idea why your cacti are jumping like that.

I find it funny that you still going on with the same subject where you clearly couldn't make even one video smooth without stuttering after a whole night of trying.

This is the best you could do:

Your video with the blue objects is clearing stuttering and this is one demo with just two events and a few objects on the screen so really it should have been very easy for you to make but you couldn't, though you still carry on with the same thing.

If I was you I would definitely not bring back the topic after that night lamo ))

If you consider the blue bars stuttering, we have decidedly different definitions of what stuttering is. Looking back at it, I do see some stuttering on the blue bars now, but only right after hitting play from stop, but not when I rewind/scrub back to the beginning after it's already playing. I'd chalk that up to my computer being a potato as it loads the video into memory. Regardless point was to show the difference between recording at a low fps and high fps. Which has nothing to do with the OP's topic at all.

Though not sure what has to do that topic with the OP's topic as the topic you mentioned was for recording videos for trailers etc... and the OP has stutters at the Gameplay not recording.

I understand that the OP has stutters for gameplay, I was saying that it is harder to see the problem from a video when the recording framerate doesn't match the game framerate.

No parallax on any layer.

I switched off all layers except from the front plants.

The frame rate in this case starts at solid 61 and doesn't move under 60.

I still see the jank although it is slightly less. Every few (4-7) seconds there is quite a big jump in the position of the plants.

Ran some tests to try to reproduce. It's much more noticeable for me when my estimated cpu usage gets high, according to the debug preview, at about 70%+. FPS stays above 55, but it's when it changes that jank is noticeable, especially for linearly motion. Lowering the number of objects/cpu load to under 50% made the FPS much more consistent.

Turning off Vsync actually made it worse for me, as it drove the CPU use (and fps) up, causing significantly more jank, even though the fps was high.

If the source is actually a CPU limitation, see if there's anything you can do to lower CPU utilization. If it happens in an empty project with low CPU utilization, I'm going to guess that some background software is possibly taking CPU time away from the game, like for example how some antivirus softwares can potentially slow a system to a crawl when running a scan at high priority. Not sure if that's a thing that can happen on a mobile device though, depending on how the device prioritizes it's CPU. Maybe some sort of power saving throttling? I doubt that would happen when actively using the device though.

Thanks for testing with vsync disabled, it's interesting that noone else is getting similar results to me.

Perhaps the jittery issue I experience is a different jittery issue to what others are experiencing, but for me I do get perfect results with vsync off, but when vsync is on, even if my monitor refresh rate is set to 60hz,144hz,or 240hz, I can see jittery issues every few seconds. Very unusual.

That smoke/steam looks really smooth ...

Did you try a test without it?
