Upgraded GPU from Nvidia 3070Ti to Nvidia 5080 Now VP22 slow crashes

I upgraded GPU from Nvidia 3070Ti to Nvidia 5080 so I could preview Canon 4K 10bit 422 MP4 video files smoothly on the Vegas Pro 22 time line and to speed up rendering of 4k video. With the 3070 Ti gpu I had to create proxies in VP 22 to preview smoothly on the time line and rendering of 4k video was slow. However, with the new Nvidia 5080, VP 22 is sluggish, takes a full minute for me to drag a file from VP Explorer to the time line and gives message Vegas Pro 22 Not Responding. Frequently the video file has no video just audio. So now VP 22 is unusable for me unless I can find a fix.

I'm sorry to hear about this.

Would you be willing to try to do a clean reinstall of the NVIDIA driver? Remove it with this tool: https://developer.nvidia.com/downloads/cleanup-tool and then install the current studio driver.

Beyond that a reset of VEGAS could help- hold control + shift upon startup.

I don't think VEGAS yet incorporates support for NVIDIA 10-bit 422 decoding.

If you get a chance could you also fill out the VP 20 benchmark in my signature to see how this GPU is performing in general in VEGAS (after you redo the driver and hopefully get it working?)

I tried turning off GPU acceleration in Video Preferences. VP 22 is still very slow on starting the program. But it can play the Canon 4k 10bit 422 files in Preview auto mode smoothly on the timeline with GPU acceleration OFF. I had to create video proxies for smooth play back on the timeline in Preview mode with the old Nvidia 3070Ti. However, VP22 is very slow at rendering to either 4k or HD GPU acceleration OFF. Also, with GPU acceleration turned on I can play 4k 8bit 420 mp4 files smoothly on the time line. I just have to avoid using the 4k 10 bit 422 files with GPU acceleration turned on. I may wait and see if Magix Support tells me VP22 does not yet support Nvidia 10-bit 422 decoding.

With GPU acceleration on do you get a different outcome with this file https://www.swisstransfer.com/d/7c32eef0-af66-4fd9-9024-bd52a5022802

Either is plays with CPU, plays with GPU, or the same black screen?

When you say GPU acceleration off do you mean in preferences/video or preferences/file io and hardware decoder off?

Preferences / video / GPU acceleration of video processing / Off

First, did you do the driver reinstall or reset? Overall video processing shouldn't affect decoding.
Second, did the benchmark project play back and render? It's a known good project (so media is not a factor).
Third, what happens if you leave preferences/video on but turn off hardware decoding in preferences/ file io?
Fourth, what happens with a non-422 file like what Alan shared.

This file file https://www.swisstransfer.com/d/7c32eef0-af66-4fd9-9024-bd52a5022802 is black in the preview window with GPU processing on or Off.

Okay so you need to try step 1 then, driver. After you do the clean-up the current one is here: https://www.nvidia.com/en-us/drivers/details/247854/

Actually Alan's file is 10-bit 422 AVC and looks like it was modified and isn't directly from a camera.
I loaded that file into 22.250 with my RTX 4060 mobile and it doesn't preview and slows VEGAS to a crawl.

I see no evidence NVIDIA 10-bit 422 decoding has been implemented in VEGAS so would expect it to fall back to a software CPU decoder for such footage. Here it's Mainconcept AVC.

I can't play it either wondered if 5080 could. Full file can be downloaded here (3.3GB) https://billykyle.wetransfer.com/downloads/45085a17b0b28591be27fe7757d6bb9820250513212358/a5309d

Just downloaded one of the mp4's and that played smoothly in preview best full at my PC (specs in my signature).
