UPDATED! 32-bit color crashes renders with GeForce driver

v17 build 421. I recently move from Quadro to GeForce cards (RTX 1660 and RTX 2080 Ti on two different machines. Both machines had Quadro prior. RTX 1660 runs game drivers and RTG 2080 TI runs Studio Drivers.

However, a previous project that worked fine now crashes on hangs or crashes if (1) 32-bit color is on and (2) GPU acceleration is on. It crashes o any video codec I've tried (MP4, MPEG-2, Vegas Intermediate). Audio renders work fine.

Turn off 32-bit color or GPU and render works fine so almost certainly a driver problem.

If you aren't editing 10 bit or higher video, don't waste your time on 32 bit color. There are very few cases where it provides any real benefit.

But that is exactly what I'm doing - large amount of VFX with alphas and layered 10-bit video.

When you mentioned encoder, do you mean encoder that was used for encoding your sources/intermediate or encoder you are using for rendering the project?

I'd try to disable GPU decoder and so4.

P.S I do not have the issue while rendering my 32-bit projects

Must both 32 bit compositing and GPU acceleration be off for it to work, or is it one or the other?

Glad you are using 32 bit compositing in the appropriate project and source environment.

No, one or the other, not both. It works with either on but not both on. Reproducible on two different boxes.

Encoder for rendering. Yes, turning of GPU acceleration or 32-bit works but with my previous Quadro cards did both no problems.

My suggested was to turn off GPU decoder only (on File I/O tab).

Decoding is for accelerated playback as I understand it, I only turn on 32-bit for rendering, 8-bit works just fine so I don't see how this is relevant.
