Beta 3 crashes when loading in older project with magic mask

I upgraded to a RTX5070 ti and Resolve 19 no longer worked right. So I updated to 20 Beta 3 and the performace is not great. It decodes 4k 4.2.2 better now, but playing regular 1080p 4.2.0 videos it seems to struggle and if they are layered in the edit page it tries to render everything under the top layer.

But the real problem is going to a video with magic mask (older version) it just completely hangs and blanks out, and I have to hard reset from task manager.

Wish I never bothered "upgrading" because the new NVIDIA card won't work right with anything now. CUDA errors in my AI software so don't know what's going on. I installed the latest drivers

Having constant random crashes here with the 5070TI
I still have my old 3080ti. I'll try switching it back to test it out.

So I'm not alone then. I seem to get better results after leaving the computer for a bit and restart, almost like it's building a cache in the background. Weird how magic mask is still the old version, unless because I imported a project from before the upgrade so it's still using that? I don't know, I'm a bit lost and want to send this card back. It's noisy anyway and the thing is so big it completely blocks fans on my mobo

The 50 series from nVidia did have some issues that were not fully addressed until version 20. I don't know if BMD will add that fix into 19, so users with 50 series cards should at least consider the upgrade, even though it's only Beta.

For folks having issues with the Beta, there is a separate forum section.

Today I worked all day with no issues, no crashes.
It was a new project created in DR20 B3.
