Xbox One X - Set Resolution to 720p

Question

Hi.

We're developing for Xbox One X/S and are facing a very harsh situation.

Due to implementation, and maybe we need to improve our rendering process, we are stuck at a 1920 by 1080 resolution, but the game we're creating runs a bit slow, so we're trying to set the game resolution to be 720p.

Is that possible using C++? What if we want to set the video mode to 4K, what would be the steps to accomplish this?

Thanks in advance.

Best regards!
