Which version runs best on your system? DirectX or OpenGL?

LaTropa64 · 2008-03-03, 07:11

On my system, the main XBMC gui in the SDL OpenGL version uses much more system resources than the DirectX version.

DirectX - roughly 2-5% CPU

OpenGL - about 30% CPU

Video playback though makes no difference on the systems resources with either version but it does seem to work and look better on the OpenGL.

I know it is still early in the development and I'm not really looking for a solution at this point, I was just hoping for something to talk about in here while we wait.

and this has NOTHING to do with dx vs ogl.

this has everything to do with xbmc_pc being very much limited in its fps while the ogl version not being limited

Indeed like the "Grumpy Bastard Developer" said the directx version has a bunch of wait calls that are crippleing its framerate so its useable and nobody has probably even looked into it for the sdl version
I suggest you turn on debug logging and look at the FPS in the debug info

Ahh, okay. That makes sense. I was wondering if maybe my video card was offloading one and not the other. I just turned on the debug info and the sdl version is at 59.9, while the directx shows 100.0.

FYI; the SDL/OpenGL version will be the only "XBMC for Windows" that Team-XBMC supports

The DirectX version that builds from the SVN trunk will only ever be for skin/python development!

That's why we try to get our hands on some recent SDL build

Notice the "will be" though, Team-XBMC do not get offer end-user support/help for it.

I think the DirectX version was the one that came in the T3CH releases
