Notes

This week's beta release includes some new fullscreen modes Integer scale inner and Integer scale outer. These work the same as Scale inner and Scale outer, but much like Letterbox integer scale mode, will only use a whole number scale factor. This provides new options for entirely filling the screen, but preserving pristine pixel art, ensuring every pixel is displayed at the same size.

We've also added a new Fixed framerate mode, where you can choose a specific framerate like 30 FPS. This also applies a fixed delta-time (dt) value. We still recommend using v-synced mode for a smooth display: fixed mode uses a timer to schedule frames and so it won't necessarily correlate to the display refresh rate and so can still end up looking janky regardless of the fixed framerate you choose; and the fixed delta-time value means things will go in to slow motion if the target framerate can't actually be achieved. However it can be a useful tool for saving battery with a lower framerate, for quick test projects, or another way to test your use of delta-time is correct by checking movement at different framerates.

For this release we've also done a fair amount of work to optimize the editor memory usage. Construct is capable of handling multi-gigabyte sized projects, but this can end up using a lot of memory in the editor. We've done some further work building on top of other optimizations in the previous release to make the editor significantly more efficient at handling large projects which should help avoid possible out-of-memory errors. These include some fairly far-reaching changes, so be on the lookout for any new issues that might have been accidentally introduced.

As ever there's a batch of other changes and bug fixes. Happy testing!

  • twin we be working towards that fps limit hoorayy

  • Great update!

    But I am not sure about the "fixed" part of the fixed fps mode, I would rather have it purely as a limit. We can do the slow-mo if we need it using the set min/max delta-time action.

    Alternatively adding another mode "fps limit" would be good.

    • Yes, please make it an option if this gets added.

      Fixed mode is very useful.

      It makes the fixed time step mode of the Physics Behavior actually do what it should. And for certain games slow mo is a more desirable outcome then inaccuracy which would lead to broken gameplay.

    +! That's really very good!

    Together with the refined WebGPU plugin for Steam and the upcoming industrial plugin for Spine, this will be just great. With large projects of several gigabytes, thank you very much!

    P.S

    We are looking forward to 3D support on WebGPU )))

  • I'm looking forward to testing the new integer scale inner/outer. I had to do a lot of heavy lifting to get the non-integer scale outer to work in a somewhat "pixel perfect" way.

  • Ooh new scaling modes!!

  • Fixed framerate is huge tbh this has been asked for ever since i started using Construct thanks so much!!! 2026 off to a great start. Love the focus on these core functionalities ^^

  • "Audio: playing and then immediately stopping audio sometimes did not stop"

    Yeahhh This works rn!! Thanks for fixing it.

    Please. Then fix it on Construct 3 r449.3 LTS too.

  • Very nice, thank you :)

  • YO! The absolute insanity of this add-on is incredible!

  • Quick question. Where's the fixed framerate mode in the menu?
