Game speed is affected by display refresh rate

[overflowy]

Hi Vadim,

First, thank you for making this ❤️

On my Pixel 7 Pro @ 120Hz display refresh rate, the game is so fast it is unplayable:

Switching to 60Hz fixes the issue

Hi. It's true. I have not studied the problem with the speed of the game on different devices. I saw it myself when I tested it on Xiaomi Red Note 10 Pro and Samsung Galaxy M31s. Maybe someday I'll be able to figure out the reason and even out this moment. Despite the fact that these two devices had 60 Hz

Sounds like you need to implement delta time for the physics/game code. This would be implemented in your render loop (game loop). https://en.wikipedia.org/wiki/Delta_timing

For a moment I thought I had a "skill issue" moment, but I can confirm setting it to 60Hz fixes it. I think this issue should stay open to avoid duplicates.

Yes, I've already seen it, thank you. There will be time, I will study this issue and correct the situation

Unfortunately it's not fixed for me.

Please check the new release, the problem seems to have been solved: v1.1 (release)

I downloaded and installed the latest version (after uninstalling the previous one)

I confirm it has not been fixed

Yea, same here. Can confirm

Huawei Nova 10 pro (120Hz) I can say that the problem is not solved. Delta time still doesn't work correctly...

120 fps -> speed x2

Unfortunately, I will not be able to record the phone screen while playing, since when I turn on recording, the frame rate drops to 60.

I just tested it, speed seems fine, but some inputs get ignored:

Vadim, thank you! this actually solved the game speed problem at 120 fps!

I have moved the topic due to a new problem https://github.com/VadimBoev/FlappyBird/issues/8

You need to multiply each movement by time.deltaTime (which in your case you need to calculate based on last few frames). Nevertheless it's incredible what you've created!

I have already improved the algorithm, everything is fine
