Handing textures over to OpenGL is done once they are
Right. But some of the "global" shaders always seem to be loaded. For example, start at LOWI. Doesn't matter whether shaders are enabled or disabled - you still get the warnings about the proprietary "sea_foam.dds" textures being loaded. Not sure whether it's really referenced by the scenery there - the sea should be really far away ;-). > > If someone was looking into improving the effect/texture loading code: > > it would be great if loading shader textures could be made optional, > > i.e. defer loading them until first access. > Well, what do you mean with 'first access'? To somehow create the "effect" object when the model references it, but to defer loading the texture until the effect condition becomes true for the very first time - which is the moment when the texture is actually needed/accessed for the first time. This would keep the feature of being able to enable shaders at run-time, while avoiding to waste memory/CPU performance on loading unnecessary textures. > > As a hard work-around, we could also introduce a new command-line option > > to disable shaders support completely (enabling shaders at run-time via > > the dialog wouldn't work then).
