...ous. However I experienced rather bad performance (at least from a game programming point of view) After a couple a profiling, I discovered, as previous discused in a post found via Google, that the bottleneck is in the ogg library. An unsane part of the CPU time was consumed in a single function : oggpackB_read. This was even more visible that I'm compiling the MMX branch. So, starting form this MMX branche, I made a rewrite of the GCC assembly code to Visual inline assembly. By the way I tweaked them to maximize instruction pairing. Then I rewrited the oggpackB_read to reduce the number of tests, pu...
