Solved Game only uses onboard graphics (AMD Radeon and 4080 Super)

[PeteWasEre]

I have a AMD Radeon on board and a 4080 Super. The game insists on using the on board graphics even when the app is set to use the high perf card in settings>Display>Graphics

Disabling the on board card (via device manager and reboot) results in an instant crash after launching the game. (i shouldnt need to, every other game has no issue with this, but a good test)

It will load at the lowest settings but is slow (as expected with the on board) with 1s game time about 10s IRL. Its unusably slow.

I updated all drivers, not sure I can do anything else.

Could you post the output of

Open Powershell ->
vulkaninfo
(type that in, then press enter, and scroll down to 'Device Info', then copy the first few lines)?

IE, for my desktop:

Device Properties and Extensions:
=================================
GPU0:
VkPhysicalDeviceProperties:
---------------------------
apiVersion = 1.3.277 (4206869)
driverVersion = 551.86.0.0 (2312470528)
vendorID = 0x10de
deviceID = 0x2208
deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU
deviceName = NVIDIA GeForce RTX 3080 Ti

Weirdly enough, on my laptop it properly selects my RTX 4060M, not my main Ryzen iGPU. Seems like on Desktop, because of Windows' bad decisions, we don't have easy ways to force devices. I've done some GPU coding before but I can't think of an easy way to force it to use your Nvidia GPU with a command line option, without them literally editing the code to allow you to switch to a different Device ID

Thank you so much for the assist.

Strangely i dont see GPU1: anywhere for the 4080 super!

@Allie_Gat0r :3 you kind person are gold! After some digging turns out my card driver was old and had a vulkan issue. I had disabled update because a year ago a new driver broke MSFS and forgot to re-enable. After drive update its great.

A million thank yous!
