Frame limiting or frame smoothing

[tumira]

I would like to request frame limiting or frame smoothing built into the engine. Currently I and others encounter these strange bug , stuttering or jerkiness when rotating or when looking at certain angle with flash light

and this

Frame limiting based on user monitor refresh rate or even let user define their own preference would be a cool features to make leadwerks game smooth and not jerky or stutter.

 

My current solution is to install MSI afterburner and set the frame limit manually to 60 (based on my monitor refresh rate) would be great if this is built into the engine especially when vsync is on.

A frame cap limit would be nice!

I thought this already existed. First, turn vsync on but may want to double check the forums too.

I mean, force the game to run in a arbitrary frame-rate, like force a game run on 30FPS (not every genre need to be 60FPS). Vsync ("context:Sync(true)") will try to match the refresh rate of the monitor.

Yeah. Do a little digging and found out about Time:Step() . If i added this before Time:Update() , the stuttering is mostly gone. It is now smooth when rotating around object with vsync on..

 

But adding a Frame lock or frame limit manually like 30 , 60 or something might be better. For example I want to lock it to 30 or 45, I dont think this is possible for now unless using third party tool.

[DooMAGE]

yeah looks like it's not possible now, but would be a nice feature.

You could if you just measured the time since the last frame and add a call to Time:Delay() if it's going too fast.

@Josh

 

Example ? If I want to limit it to 30fps or 60fps ?

[Brutile]

I'm just guessing here, but probably something like:

 

local fpsLimit = 30.0
local deltaTime = 1.0 / Time:UPS()
local limitedRate = 1.0 / fpsLimit
if deltaTime < limitedRate then
Time:Delay((limitedRate - deltaTime) * 1000)
end

Wohoo. I'm impressed with leadwerks community. I wonder why I left Leadwerks last year..

 

Thank Brutile. It works, sorta. I think I get it now. Need few tweaks.

 

Thanks again.
