Will a separate sound card improve performance.
I'm currently using onboard sound with my Gb ud5 x58 and the cpu has to do all the sound work. Would adding a sound card help fps by taking load off the cpu. I run xfired 6990's on an i7 920 at 4.2ghz so I'm a bit cpu limited. If a sound card would help should i get one with 64mb on board memory?
nope, arma doesnt use hardware accelerated sounds, and if it did it wouldn't matter because they're probably in a separate thread (as in not in the render thread)
