NVIDIA RTX 5090 GPU vs. Intel/Auto

I have the latest version of Davinci Resolve Studio and just bought a brand new $6K high end 18inch Sager pro laptop with the following specs. It's a powerful laptop.

Intel Core Ultra i9-275HX Processor ( 24 Cores, 36MB Cache, 5.40GHz Turbo )
NVIDIA GeForce RTX 5090 GPU with 24GB GDDR7 Video Memory
192GB Dual Channel DDR5 SDRAM 4000+ MHz - 4 X 48GB
Four - 4TB Crucial P3 Plus M.2 PCIe Gen 4 NVMe internal SSD storage (16TB total)
Windows 11 Pro 64-Bit Edition


My question is should I set the GPU and Memory menu to NVIDIA only, or have both GPU options checked on? I also have the CUDA selected on not auto.

Also, I have the laptop itself in the NVIDIA "physics menu" set to NVIDIA ONLY vs. Auto, CPU, or NVIDIA.

The defaults in resolve should work. 50 series now has better decoding support than intel. so you should be able to ignore the igpu.

The physics setting is irrelevant. Leave at default.

Do note you need to run the Resolve V20 beta for 50 series support. So expect some teething problems until near the new year.

Nvidia drivers are also a minefield. If you get problems try the absolute newest or go back a few weeks.

Okay. It sounds like I have the settings correct. I have unchecked the intel igpu and have using the one NVIDIA GPU checked on and the CUDA is selected not open CL. That is for AMD GPUs is my understanding so I'll leave it at CUDA.

If I were to check mark both GPUs on, will it run and render slower vs. just check marking NVIDIA only active?
