Re: Thunderbird with Lightening
Absolutely. On multiple products. It's also worth pointing out that what each or any of us considered "smooth" might be choppy or unusable to others. I, for example, find anything slower than 60fps unusable and I tend to be picky about my mice because some setups - certain wireless USB mice, for example - have noticeable (to me, at least) lag when compared to wired PS/2 mice.
Compared to Josh, however, I might as well be playing a slideshow. For him, anything under 120 FPS is unusable and he's picky about which PS/2 mice he uses because lag matters that much.
Maybe you found a magic combination of hardware and software that works great. If so, congrats! For me, I haven't had such luck so far. And I'm far too poor to rebuy all my gaming gear. To date, none of the software produces anything usable for me, and I cycle through and retry every 8 months or so.
