GPU-assisted rendering is not a feature of Premiere Elements 13.
Premiere Elements is a pretty efficient program that tends not to grab a lot of RAM, where you'd see your biggest performance boost in 64-bit. But the 64-bit architecture does give it room to grow.
Meantime, remember that performance is a combination of several factors, including, most importantly:
* The speed of your processor
* The format, resolution and codec of your source video
* The length of your project and/or the individual clips that make up that project
* Ho much RAM you have, particularly between 4 and 8 gigs
* Your Premiere Elements project settings and how closely they match your source video
* How many effects, titles and other non-rendered items you add to your movie
My computer has a GPU and I have been disappointed that PrE does not seem to take advantage of it. For an experiment I bought a competitive video editor that does have GPU use options. I put a batch of clips into both and was amazed to see no significant difference in performance.
That's interesting, Bill!
My guess would be that, unless you're working on a really high-end video, GPU rendering and 64-bit architecture with tons of RAM aren't going to make huge differences in your editing performance. Not nearly as much a difference as a good, fast processor anyway.
I dropped a new power supply and high end graphics card into my computer last year and it really had no noticeable effect on my AVCHD video editing. But boy could I feel the difference when I started doing effects editing in After Effects and HitFilm!
