hello;
i’d posted couple of messages over the past week, related to DirectX and
WinDIB and only traction i got is, “can you post in text instead of html?”
is this forum “closed” to discussing or sharing experiences about windows?
to reiterate, the problems are:
a) SDL crashes in fullscreen mode when using DirectX SDL video driver
b) SDL positions the window in 0, 0, when using DirectX and when
SDL_WINDOWID is specified and not within the window
please help if you can.
kindest regards,
sheshadri
hello,
The sdl driver has been made non-default because it doesn’t work very
well on some newer computers - unfortunately.
Is the windib driver ok for you? For many it seems windib is just too
slow - making older computers unable to run software they used to be
able to run.
Have you tried:
- your code on other computers?
- older versions of SDL?

Hello !
a) SDL crashes in fullscreen mode when using DirectX SDL video driver
Have you tried if testsprite, with the
same settings, shows these crashes ?

hi;
thx for ping back… (doesn’t feel so lonely anymore grin)

I am chasing slower performance with windib - w/dual core it takes up
close to 50% cpu; partly due to ffmpeg decoding partly due to rendering
video… other computers at work have reported even worse performance
hit. the os i’m using is xp. and directx libs i compile & link SDL
with are 9.0c, compiler vs8
directx is much faster (only chews up between 8 and 13% cpu on my
laptop) but has fullscreen issues… SIGH
i’m on 1.2.12… are you suggesting that older sdl’s are better
performing than newer… which version do you suggest i try?
thx.
kindest regards,
S-> cheers,

hi;
thx for pinging back.
i’d tried the test under visual c folder but not testsprite. i’ll try
that one now and report back.
thx again.

No, it’s older versions of DirectX that are better performing, on
certain hardware.
DirectX 9 removed DirectDraw, the 2D component that SDL was using, and
replaced it with an emulator based on Direct3D (for backward
compatibility). On computers that have accelerated 3D, it is probably
just fine, as fast or faster than the DirectDraw in DirectX 8, the
problem is with older computers that do not have 3D acceleration
hardware. On those computers, DirectX 8 would give you excellent
framerates, DIB wouldn’t be as good (as you found out), but would be
workable, and DirectX 9 very well might be unusable.
The choice was made to default on the DIB backend, so at least it’s
workable. Since the performance of the DIB backend is highly dependent
on CPU and memory bus speeds, and those are going up in newer systems,
it actually works out pretty well, if a bit wasteful.On Wed, Jun 25, 2008 at 8:36 PM, Sheshadri Mantha <sheshadri.mantha at schange.com> wrote:
