We created two identical projects based on Steema's FastLine_RealTime.pas example.
One project is VCL and the other is FMX.

We notified that when we add Charts in the FMX project the performance is decreased.
The frequency of one chart is 125 fps, two charts is 75 fps, three charts is 54 fps.
In the VCL project the performance is the same for one, two and three charts.

See attached images.

The question is if it is possible to get the same performance in the FMX project just like the VCL?
We tested Steema's TeeChart Pro v2013.09, Delphi XE5 Enterprise on Windows 8.1 Pro

Thank you

Hello,

I've done the first part of the test, the VCL part and I get a slightly different result than you.

Here the specs of the machine & environment I use:
- Processor: Intel i7-4771
- RAM: 16Gb DDR3
- Graphics: NVIDIA GeForce GTX 760
- OS: Windows 8.1 x64
- IDE: RAD Studio XE8
- TeeChart version: TeeChart Pro v2015.15

Here the test project I used:

VCLFastLineCharts.zip: (2.69 KiB) Downloaded 931 times

Here the results running the project above "without debugging":

: 1VCLChart.png (16.78 KiB) Viewed 7626 times

: 2VCLChart.png (24.23 KiB) Viewed 7626 times

: 3VCLChart.png (30.41 KiB) Viewed 7626 times

So I'm getting differences in VCL also. Do you see any setting in the project I'm missing comparing with the test you did?
Could you please try my project in your environment?
