VMS 10 HD and avchd preview playback a scam?

I have mixed feelings about VMS 10 HD playing my Canon 550D (hdslr) files in full hd.
I get a full 24fps in preview only when I leave activated 'adjust size and quality for optimal playback'. (It is activated standard, actually). If I deactivate it, fps drops to 12fps or below, on my system. But even when activated, it seems buggy, and framerates will drop to under 10fps, unpredictably and frequently.

I have been using VMS8 Plat on my system for two years now, and honestly, I can't see any improvement right now. I get the same framerates, you know.
(I admit version 10 does offer rendering to full hd mp4 files, while VMS8 only offer wmf full hd).

I have a CUDA enabled GPU (nvidia 8800GS). I'm running the trial, build 179.
Critical detail: the program crashes instantly when I try to open the help file.

Hm, 'adjust size and quality for optimal playback' seems like a euphemism, a scam, really, for hiding the fact that nothing really has changed under the hood.

EDIT: I'm not saying VMS10 is bad. For many users, it will be a powerful NLE with lots of useful features. I'm just trying to find out if this release justifies updating from vms 8, and for now, my conclusion is it isn't. I'd rather transcode my files using mpeg streamline.

Also, using the 'adjust size and quality for optimal playback' seems to activate some transcoding in the background. It takes a while before the full 24 fps or whatever becomes available.

The CUDA support for AVCHD appears to be only for *rendering* at this point...

Do we know if any other GPUs can be used to accelerate rendering, or is it only CUDA-enabled GPUs?

Sony Creative Software's official release announcement very explicitly states that only NVIDIA CUDA-enabled GPUs can be used for GPU-accelerated AVC rendering. Here's what they say:

"GPU-accelerated AVC Rendering: Vegas Movie Studio HD Platinum can now use the Graphics Processing Unit (GPU) in equipped computers to improve AVC rendering performance and speed, which allows final projects to be published faster than ever before. Users with a CUDA-enabled NVIDIA® video card are able to encode to the Sony AVC format using GPU-accelerated rendering."

I don't see any way to interpret that as including ATI GPUs. Which makes this new feature a bunch of royal crap.
