Minecraft... 30FPS... Mine all the Coal, Iron, Redstone, Gold, Diamond, and Obsidian you want...
You can mine with an android phone... so I know it is possible. Just not sane!
I am sure someone out there actually knows how to program nVidia cards to do what needs to be done. But most just copy-paste "known code", and don't try anything beyond that.
I was one of the first to propose the use of the GPU's super-fast memory mods, to do complex math with one instant POP, by simply using a graphical overlay that was actually a math formula, as a layered set of images. While others were still trying to push individual "commands", without success. Funny, you can ADD, MULTIPLY, SUBTRACT, (limited divide), and SHIFT, all with a single image-buffer and an overlay, onto another image, which is actually a giant array of a bunch of numbers. Lightning fast, and great for using numbers that are longer than a 64-bit, or even 1024-bit, or 32,000-bit variable/array.
We are at the mercy of the coders... The coders are at the mercy of what they are familiar with... What they are not, they initially copy-paste (or recycle), so they do not keep reinventing the wheel. However, the wheel sometimes need to be reinvented for racing on an oval track, in the desert, on dust, by crappy drivers in sloppy cars.
