Yes! I've noticed the transitions are noticeably faster. They move very quick now. Almost too fast. Only thing odd is that I get no voices - but that happened once before and I think it's my audio setup. Just got to remember how it does that.
I've found the BT engine not to be that power or processor hungry (save minor bugs) or GPU intensive really. I ran it on my lowly 280X and AMD FX 8150 and it ran spiffy and speedy really. It wasn't until 1.6 that any speed issues (for myself) have cropped up. In fact it runs so well that I've just not hooked up my 2nd 1080 in the i7 machine cause I'm just too lazy. :-D
Sound is working fine. It was me. Power failure I forgot about. Have to resent the Z-5300 speaker system or else certain channels (voices in BT) don't play.
