Hello. i recently bought kotor 1 and i tried to run it on my laptop. Turns out there is an issue with multiple GPUs.
My setup has a mix of Intel HD 4400 as the main processor with a R5 M330 as support (the integrated graphic is stronger so it does the computing while the dedicated provides the VRAM) now this means my radeon software has incredibly limited settings.
my screen resolution is 1366x768

I get a black screen most of the time but the game is running. sometimes alt tabbing out and back fixes it but not always.

widescreen with unwis works but it has to be minimum 1530x864 otherwise game crashes therefore a part of the game is not on screen. including the hud. can't change the window's resolution through radeon software as suggested

windowed is only a tiny window and can't change the resolution of it nor set it to borderless. with windowedborderlessgaming software

disabling one graphics card in the device manager either keeps the current issues or game doesn't start at all.

What do i do?

I dont know if it's quite the same issue or related, but whenever FMV scenes begin to play, my PC keeps on dropping back to desktop, then the game, the desktop, then game - sometimes I have to click the icon in the task bar at the bottom to get the game back, with still more flips to desktop and back. But it rarely crashes, persistence will get the video scene to play eventually. It's extremely annoying though - and seems to be something to do with switching between resolution modes. I think it's really down to Windows 10 not being too compatible with KotOR1 and maybe not much can be done about it.

Not much help I know, but that's my opinion on it. :/
