Can you give an example?
TParent = class

The above has no effect.
What do you want to achieve?
That rather constantly doing copy paste of original properties and
even methods to foreword to a new class, there will be a tool for
that.
With my Redis client, I have a basic class that contain such
properties, and few classes that inherits them, and require to have
the properties inside.
It would be nice, but not a real demand to have such support.
The CTRL+SHIFT+C is the tool for the job imho, because it completes
code declarations, but as you discover, it does not do that at the

I think that part of the interface inheritance feature that will or
might be designed, it should support also this.
I still don't see the point.
The properties have the same visibility, type, getters and setters.
I could understand the demand for a tool doing the opposite: to clean up
such duplicate properties.
Or a tool to raise the visibility of inherited properties.
In my knowledge in Pascal, if the child does not pass the parent
properties, then they are not visible in the child.
For example in the RTTI you will not see the published property
because it was not foreword to the child.
No, this is wrong. A class always inherits the properties of its parent.
The following example prints 42:
=== example begin ===
program test;
{$mode objfpc}
{$apptype console}
uses
typinfo;
type
{$TYPEINFO ON}
TTest = class
private
fFoo: LongInt;
published
property Foo: LongInt read fFoo write fFoo;
end;
{$TYPEINFO OFF}
TTestChild = class(TTest)
end;
var
t: TTestChild;
begin
t := TTestChild.Create;
t.Foo := 42;
Writeln(GetOrdProp(t, 'Foo'));
end.
=== example end ===
So your suggested tool is basically useless.
You only need to write property Foo; in a child class if you want to
increase the visibility of the property (e.g. from protected to public
or published)

Sven

Looks more like HD speed is a bigger issue than PCI-E transfer speed. I did some tests with that, including with a x16 card in a x1 slot, and didn't notice any difference. (P35 mobo) The speed (with a non integrated GPU) is always about 1mb/ms so about 1gbyte/s. But that is for a single uploaded frame (see below). If I increase the framerate (generate a new frame more often), I see that the times get significantly (several times) longer, so the opengl call blocking time is not entirely the same as the time the card is busy.

(transformed to RGBA or ABGR while uploading) - the CPU bandwidth while copying the data from user space - the PCI-E bus while transferring the data I simply measure my frame upload method times, which are zero copy in my own code, thus entirely bound by opengl. This consists out of one texture upload, and some linedrawing which is done with ARB buffers. For OpenGL it is hard to predict anything.

(HD5400 series from ATI vs older GF8500's) This is not only old vs new it is also ATI vs NVidia and it is only two cards. Nothing wrong with that but I would not draw general conclusions from that. Enabling PBOs sounds like there is a specific way to use them but there isn't. Using one, two or a pool of PBOs are the options you have for using them for this case and they all should differ in speed (and implementation complexity). I have not tested this but reliable sources (forum on OpenGL.org) say that how and when you map/unmap the buffer makes a difference, too. Before mapping the buffer calling glBufferData with null as data may speed up the mapping time. I simply measure my frame upload method times, which are zero copy in my own code, thus entirely bound by opengl. It sounds like you measure OpenGL call blocking time which may or may not be equal to the real upload time. If you use PBOs you most likely map/unmap the buffer in that method, too, which I don't consider upload time. I don't want to question your method just saying that measuring OpenGL times is not as straight forward as it seems to be. That's why NVidia provides a complete SDK (PerfSDK) to measure your OpenGL performance. In the OpenGL world nothing is as easy as it seems. so the opengl call blocking time is not entirely the same as the time the card is busy Of course not. That's how OpenGL works and what makes timing single OpenGL operations difficult. Nonetheless some interesting info you gave there.
