Using gpu through the motherboard output.

[UltraVires2.0]

can anyone explain how this is possible? im running my rx 570 through my motherboard output and getting it at 100% usage in dota2.

my gpu is a mining version so only 1 dvi output, i have a hdmi only new monitor, so what i did was connect my new monitor to the motherboard hdmi out and made the integrated gpu as the primary display device thru bios and had it as the main display where i ran the game.

im puzzled as this only works for dota 2, while in other games the pc uses the igpu which i set to force 64mb only igp memory.

 

has anyone else tried this? i know its possible for an nvidia card as seen in the p106 video with linus and anthony, but none for amd ones.

If you're using a video output from your motherboard, then you are not using your GPU at all.

yes thats what it should be right? but you can see from the screenshot that msi afterburner the rx570 is being used at its full clocks, and i know for a fact that the vega 8 on the 2200g cannot run dota at 90 fps ultra settings 1080p. thats why im confused coz it does this only for dota, not for other games

i sorta figured it out, the reason why its only in dota cause, dota allows players to choose the API, with vulkan i can use the gpu through the motherboard output, but any other API, nah.
