Hello,
I just installed DaVinci Resolve 19, I was prompted to go through the process for GPU Optimization. I saw that optimization process it was taking a while, so I went upstairs to do a few things... When I came back, my computer went to sleep and I couldn't wake it up... (Sorry new Windows installation and I didn't change the power settings.) In any case Windows logged off and shut down Resolve. I looked through the menus to see if I could invoke the optimization again, but could find nothing.

Is there a simple way to invoke the GPU optimization that I might just be missing?

Thanks!

I've only ever seen it at first run. I'm unaware of any way to invoke it manually.

신경 엔진 최적화는 TensorRT.cache 파일에 저장됩니다.

Windows에서는 다음 경로에 있습니다.

C:\Users\USER_NAME\AppData\Roaming\Blackmagic Design\DaVinci Resolve\Support\DVIP\Cache

여기서 USER_NAME은 Windows 사용자 이름입니다.

해당 파일의 이름을 바꾸거나 삭제하면 Resolve에서 다음에 실행할 때 최적화를 수행할지 묻습니다.

Neural engine optimizations are stored in the TensorRT.cache file.

On Windows, it is located in:

C:\Users\USER_NAME\AppData\Roaming\Blackmagic Design\DaVinci Resolve\Support\DVIP\Cache

Where USER_NAME is your Windows username.

If you rename or delete that file, Resolve will ask you if you want to perform optimizations the next time you run it.

I wonder if this has any effect on your problem.

Yes. In Davinci Resolve -> Preferences -> Memory and GPU -> untick Use neural engine optimization for NVIDIA -> restart Davinci.
Then tick it back on -> restart davinci
It will now do the optimization step.

Nice tip, Mads!

Thank you leesang and Mads! I wish though BMD offered a simple intuitive way to repeat GPU optimizations because installed video cards change, configurations of video cards change, video card drivers change, ...

When I do that, I am automatically prompted again.

I don't believe it's required for driver updates, though.

That is good to know, thank you

FYI, I just switched from an RTX 4090 to 5090. Reinstalled drivers, several reboots, etc. And this was not triggering automatically when I launched Davinci. Thank you folks for explaining how to trigger it manually.
