Looks like something here has helped ex_prim in software mode too. Used to run at 4fps on my Q6600 w 4G ram and a NV 8800GTS. It now runs at 12fps with blending. Without blending its back up to 60fps, same as hardware \o/

I call that a win. Before I couldn't tell what speed it was at without blending as it would blank the screen of most things... I think if its possible to work on blending some more, that would rock.

fwiw, I get "Time = 2.88472 s, FPS = 103.996" from ex_blend_bench.
