Renat Fatkhullin:

If you read from a stored resource at compile time, you have to do it once.

I read from a dynamic one.

Mihail Matkovskij:

You have to say at which input parameters Kanvas is slow. If limit_fps: false, then it's a no-brainer... :)

Was I just looking forlimit_fps yesterday?

What's there to look for? Run the Expert Advisor and try it in different modes. Withor without limit_fps enabled.And then you will understand everything.

The whole point is to limit how often CCanvas::TextOut and CCanvas::Update are called.

You think everyone is just an idiot and that's it? Just wild and delusional - and that's normal? Why would I look for it if there was one? Download your files from those links you gave yourself a few pages ago and see that there is no field method to set limit_fps. The call is there, but the field method isn't, so it doesn't compile. But if you comment out one line, it compiles. But I've already found the page in the codebase and downloaded the archive, everything is there. I'm explaining it deliberately, otherwise you may start thinking how I could test this way with limit_fps enabled when there is no method. But who knows, maybe those links already have it, maybe files update with delay there too,

There's no point in limiting thefrequency ofTextOut Updatecallswhen comparing with label, because the comparison must be done under the same conditions.

You just downloaded a demo version, there FPS limitation works without possibility to turn it off. But you need an expert to do the measurements!

The lags are obvious. And the recording shows that 1000 FPS is the ceiling.

The brakes are in your face. Yes and the recording shows that 1000 FPS is the ceiling.

We'll figure it out, it's weird.

Exactly, at that link I wrote where to download from.

Mihail Matkovskij:

Download files in \MQL5\Experts\canvas-vs-labels\measurement\cyberdev\ and \MQL5\Experts\canvas-vs-labels\measurement\ in KB. To limit fps, set limit_fps to true in the input parameters. file: CanvasVsLabels.mq5. How to run the test is shown above. And there is a description in KB.

That was not enough for you! Then you did not understand the source code, even how to run it. Even though I've already measured them and published the results above. Now, did you download the source code? Run it? If not, then go and study at least the basics of programming. Because it's impossible! If you don't even know how to build an application from ready-made sources, what more we can say...

I am attaching the compiled file of Expert Advisor. If you still have problems using it, you really should learn how to use it. Start with the basics: What is a variable, what is a function, and what is a program! And then it goes on and on!
