Question regarding gfx drivers

[Raziel]

I have a question:

I`m trying to optimize a gl4es build of ScummVM on my platform and while it runs fine (and way faster than the GL counterpart) i' m puzzled as to why it doesn't *seem* to pick up/use the correct driver.

When starting an AGS game i this

Game native resolution: 320 x 200 (32 bit)
Graphic settings: driver: D3D9, windowed: no, screen size: 0 x 0, game scale: proportional
Graphic settings: refresh rate (optional): 0, vsync: 0
Requested graphics driver 'D3D9' not found, will try existing drivers instead
Graphics driver set: ScummVM 2D renderer
Graphics mode set: 320 x 200 (32-bit) fullscreen desktop
Graphics mode set: refresh rate (optional): 0, vsync: 0

where the driver 'D3D9' sometimes can be driver 'OGL', but in both cases it doesn't find it and instead falls back to ScummVM 2D renderer

Is that considered normal?
Shouldn't it use an OpenGL or gl4es driver instead?
Do i need to add the correct driver to ScummVM first for it to be found?

Don't get me wrong , it *IS* faster, but maybe i could squeeze even more speed out of it by using a native GL/gl4es driver instead, or maybe not?

Thanks a lot for any info

The "graphics setting" lines are debug messages from the upstream AGS engine, and refer to the setting in the AGS game config (usually acsetup.cfg).
In the original AGS interpreter, it can be Opengl, Direct3D or Software, but this setting is ignored in ScummVM. It will always fallback on the 2D renderer.
