Quote: I'm just looking for a bit of rational clarity.
All these questions have been asked many times before when it comes to 3D acceleration support, and the answer you'll get will either disappoint you or make no sense for the reasons given.
Personally, I'm not really interested in 'pimping out' the Ridge Racers of this world with higher resolutions, filtering, anti-aliasing etc, All I want is the extra FPS it would deliver.
I don't see anything wrong in using the GPU to deliver full speed on older PC's with slower CPU's, even if that meant running them at their original low resolutions and 'blocky' non bilinear filtered outputs etc,etc.
But then you'll get the response that using GPU's wont increase the speed, which bizarrely,must be a first, of a piece of dedicated hardware not helping increase the speed, maybe that's down to the way MAME drivers are coded.
I think the real reason above all, is simply a lack of time and motivation to undertake the somewhat onerous task of rewriting each driver for the 3d games that would qualify for GPU acceleration, either that or there are no Dev's with the requisite skills to make use of GPU's beyond the limited use they are put too at the moment, such as HLSL.
