Igor,
On my computer (old Win 7, Core i7 first generation, 12Gb RAM, NVIDIA GTX 460 ), while making This Show I noted:
1 Much better full screen playback. In case of this Slideshow almost no stuttering
2 Much faster encoding. I'd say times faster.
3 Even Zipping goes faster.
I don't use hardware acceleration.
Thanks for the upgrade
Best
Alex
