Dell Precision 5770 RTX A3000 Failed to Initialize

[gonzalu]

Hello,

Thank you in advance for any help you can lend. I just got a brand-new Dell Precision 5770 with RTX 5770 which honestly expected to just work out of the box with OBS but I get an error on first launch. System is a i9-12900H, 64GB RAM, Iris Xe built in and RTX A3000 12GB discrete GPU. Here is a link to the logs.

Any ideas?

After some more searching on the forums, I ran across a post for Windows 10 to set the graphics settings for an app.

After selecting POWER SAVINGS mode for OBS, it launches. However, the logs still show the NVIDIA drivers failing. I have the latest NVIDIA drivers installed.

See if you can find a setting to prioritize the Nvidia graphics. Some laptops let you force the discreet GPU to always be on even when not needed. I did that with my work laptop which is also a Precision with RTX A2000 but I don't remember how I did it!

Thanks DayGeckoArt. That seems to have helped.

I went to the BIOS and it had a setting to EXCLUSIVELY drive the external displays via ThunderBolt ports and bypass internal CPU graphics... however, the Built In display is always powered by the iGPU :(

Regardless, OBS now starts with the Windows Setting set to Performance ...

Now, how can I test that it is using it :P ... I see the logs still say both are being used?

Thanks for the hint/tip

If you set your encoder to NVENC_HEVC it will only use Nvidia, or else it won't work. If you choose one of the software encoders, it will only use CPU. If you choose Quicksync then the encoder on the Intel chip will be use
