Problems with mixing nvidia + amd GPUs

[shwiftyrift]

Hi all,

I currently have a rig that is used for gaming and mining when I am at school. I have both an RX 480 and a GTX 960 in there for mining/gaming. The AMD card is the primary card that is plugged into the monitor and the Nvidia card is solely there to mine. However, when i play games, i notice some wierd stuff such as the games lagging and the sound is really off. When i take out the Nvidia card the problem goes away. Could it be that the games are trying to run on the GTX? I don't see how because the amd card is the one that is connected to the monitor. Any help would be appreciated.

what drivers do you have installed on the graphic cards? What games do you play? What are your sound settings?

I have the latest drivers for both of them. I play games like doom, wolfenstein, fallout 4, etc. The problems really only show up in doom as that is the game that i have been playing recently. As for sound settings i guess normal? I have the speaker transmitting over Bluetooth. The bluetooth is not an issue because it works fine all of the other times.

The dx12 and vulkan games are very capable of using both gpus at the same time, so maybe it just gets confused. Does the same happen in basic 2d games?

Vulkan don't support multiple GPUs, and DX12 games need to have support built into the game engine, otherwise it'll just use a single GPU.

Oh yes I thought ut said that it was already implemented (it was under "planned features" on the wiki page, didn't see) maybe try more games that use different technologies to limit the problem?
