Well here's something interesting:
P8600 @ 2.4GHz Ubuntu 10.04 x86-64 4GB ATI Radeon HD mobility 4850/512MB GDDR3
Blitting Test: 349.2
RotoZoomer Near: 226.6
RotoZoomer Far: 227.7
Radial Blur: 187.8
3d Bunny: 93.0
running in a 320x240 SDL window under X.org, Catalyst June drivers IIRC ("wonderful" folks at AMD have already dropped support for this GPU, meanwhile IIRC my nVidia drivers support back to GF2... ATI drivers just suck anyways, last time for an ATI GPU(notebook so no "easy" fix).)
methinks that this bench is not very good, or SDL sucks at this particular application of itself.
rpi was framebuffer from "text"(it doesn't really have such a mode, it's "faked" by the GPU) mode(CLI/bash shell only).
I'll try this under "text" mode and see if it significantly differs...
Well, that was quick, I'm going to have to look into it later as it throws a segmentation fault, so I'll probably run it through gdb at some point or at least strace it... (last time it did that to me is because I tried running it from the build dir and it couldn't find it's demo datafile which I guessed correctly(who needs a readme? although ideally it would throw an error...)
Might be as simple as actually having to start in non-X mode(or quit X) altogether, but I'll check at some time later...
