It's been a while now that I've had 64-bit processors in my home computers. Of course, I moved to 64-bit Linux. I want to be able to get to all my RAM. I want the additional registers and instructions.
What I didn't want was to lose streaming audio in Second Life, but that's what happened. No more background music or lazy afternoons listening to Jaynine Scarborough's glorious alto voice and infectious laugh, or Xaxoqual Mandelbrot's excellent DJing.
Imprudence has a 64-bit version. I will try that again with an eye to testing streaming audio. Live music is a big part of SL, and I'm tired of doing without it.
UPDATE: Just tried out Imprudence 64-bit, and streaming audio works beautifully on it. Now, if only LL and Kirsten would come out with 64-bit versions, or Imprudence fixed some shadow/deferred rendering issues, I'd be a happy camper.
