I understand this question has been asked before on the forums over the years but I would like to request an update for 2021, and given 13.0-RELEASE is right around the corner, perhaps some things have been added that I am not yet aware of.
I'm running a ThinkPad T400 with an Intel Mobile 4 Series Chipset and an AMD ATI Mobility Radeon HD 3450/3470. Intel graphics work just fine on BSD using either one of the drm-kmod or xf86-video-intel driver but running
Upon inspection of the Xorg log, both drivers are loaded and then I get
and the radeon driver is unloaded again, so that X starts with Intel only. I haven't bothered uploading an Xorg log because I have a bad feeling the answer to my question will be a simple 'no'. If not, I'll readily upload whatever information is required.
On Linux I can quite easily prefix the

On Linux I can quite easily prefix the

variable to any command to run it through the dGPU and in context of games this works flawlessly.
