Vegas Pro 15 (Build 177), Terrible Preview Performance

Preview playback is abysmal. I cannot even do something as simple as crossfade two clips, even in draft auto mode. Forget any other effects.

My specs:

Intel DH67CL Motherboard
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz processor
Win 10
32Gb RAM
SSD on OS, several SSDs/WD Black HDDs.
NVIDIA GeForce GTX 750 Ti
3440x1440 display, 32 bits per pixel

I went to turn on GPU acceleration, because as per the system requirements page, under "Supported GPU":

"NVIDIA

1 GB recommended for 4K — required for Smart Zoom/Smart Scale/Smart adaptive deinterlacing, and GPU-accelerated video processing.

For hardware rendering (NVEnc):

GeForce 600 series onwards (6xx, 7xx, 9xx, 10xx)
Quadro Kxxx, Mxxx and Pxxx"

My graphics card is not listed. I have to turn on legacy support. Am I missing something? Doesn't my card fall under the recommended specs?

It doesn't matter anyway. Turning it on doesn't help matters either. I can capture a video of the video not rendering in Snagit, which in itself suggests it's not a problem with my machine.

Vegas Pro 14 handles this in Best (Full) without breaking a sweat (with my GPU selected as the preview device).

I'm using the latest NVIDIA graphics driver.

FWIW, crossfade looks fine when I render to a file.

I considered making a ticket for this, but what's the point?

I mean, tagging subclips is still broken. This has been an ongoing issue since Vegas 13 (maybe earlier?). I wrote a ticket for this, because this is a new program, right?

Response:

"​This is a known issue which will be resolved in a future application update. Thank you for reporting this issue."

My question is WHEN? All of my footage comes from GoPro cameras, renaming clips is not going to happen. I need to be able to subdivide what are sometimes lengthier clips into manageable chunks and I feel that tagging was made for this.

Tagging aside though, previewing a crossfade is about as simple as it should get. I cannot use this product. Which is a shame, because I already paid for it. :(

Thanks Nick, that definitely helps. I wouldn't say it's flawless, though, and I feel as though my hardware is enough to take what I'm throwing at it. VP 14 seems okay.

If I have my graphics card enabled, it crashes every third or so preview... So I've disabled it for now.

My question still stands as to why it only shows up once legacy GPU has been checked, despite being listed in the recommendations, too.

Also kind of embarrassed that I missed that forum sticky about rendering. Sorry!
