32-/64-bit versions won't help you here, I'm afraid -- they don't usually make a big difference in situations like this, which sound like it's about having proper drivers set up. Neither does "distro-hopping" which you're doing: picking one, trying it out, throwing it away, moving on, ... Instead of getting rid of every distribution because something (perhaps small) doesn't work, find one that you like in general
, then simply fix the thing that won't work. There is no "best" or "recommended" distribution, as it's up to you to decide which one suits you best -- Ubuntu, Debian, Fedora, SuSE etc. "big names" usually have the best out-of-box hardware support for a variety of parts, but that doesn't guarantee they work with everything. And it doesn't mean you face a wall: it could be as simple as 1) getting a proper driver for your graphics card (for example) and 2) installing it (installing a binary package, compiling the driver or something else). Or it could be a configuration problem, if the "automagic" won't work for some reason..
Search the forums here for answers to your specific problems (i.e. video lagging, direct rendering not enabled, how to install drivers for your hardware X, ...) and work them out. If you can't find an answer, create a (separate) new thread for the problem and ask -- general questions like "how to get everything working out of the box?" are hard or impossible to answer, so don't expect too much on them..try asking specific questions, like "installing nVidia graphics drivers fails with this message: xxxxxx, what's the problem?".
My best guess, based on that information, is that your system is not using the proper drivers for your hardware -- probably graphics card drivers, if you feel your video is lagging. If you tried Ubuntu, did you check the Restricted Drivers Manager tool, did it say it could install proprietary drivers for you automatically (it will, if you have hardware for which there are drivers available in Ubuntu's reposities; proprietary drivers aren't usually enabled by default)? Did you try running (for example) glxgears to see how smoothly they run? Or is the whole system "slow", i.e. takes minutes to log in, switch consoles (CTRL+ALT+Fn), open directories (with your graphical file manager) etc.?
Try to give more information if you can, to make it easier to answer -- hopefully you'll find what you're looking for soon
