[GD-General] Frame Capture

[<gle...@ma...>]

Hello,

This question may seem DirectX only but there is also HW considerations =
so I
put it in the general list.

I'm trying to improve my DX9 Engine with a video file recorder; it will =
be
used offline, to build video for a Video DVD, a huge amount of video. So =
I
want it to be as fast as possible (faster than real time if able).=20

Several years ago I was confronted to this problem with a rendering =
based
PVS system. At that time my best solution was to write a memcpy using =
movaps
from AGP Memory to System mem but I'm sure there is faster solutions. =
FRAPS
for example is doing great (~30 FPS how ?).

So the basic question is: "how should I transfer my render target to =
system
memory".=20

=20

And I have a second question, when I'll have my solution, how will =
Hardware
impact on capture performances. ATI or NVidia? GDRAM Frequency is =
important?

RAMDAC? Chipset? I'll have to assemble the perfect machine for frame
capturing so these questions are also important

=20

Do you have any ideas?
