Vulkan does not use integrated Vega GPU, uses dedicated GPU instead #438

Open twelvebarsblue opened 2 years ago

Description

When Vulkan is selected as the renderer, the 3060 is used as the graphic renderer instead of the Vega IGPU. I have directed Dota 2 to use the IGPU using the graphics option in Windows 11. I am certain its not Windows fault as DX11 renderer works with the IGPU.

My PC spec (whether its relevant or not) 5600g + X570 Strix 32gb Corsair LPX 3600 mhz RTX 3060Ti on primary PCIE 16X RTX 3060 on secondary PCIE 8x Corsair RM750W

Example Match ID (and possibly Timestamp)

What are your settings in your NVidia Control Panel? image

Its not the settings as DX11 works but not Vulkan

Also my Nvidia control panel doesn't have that preferred graphics processor option and I can only choose to use either my 3060TI or 3060 but not the Radeon iGPU

you can set dota2 only use external gpu(nvida,amd) on windows 10/11 settings or control panel off your graphic cart but if doesnt work maybe thats driver bug try ro reinstall or update driver
