#LS not working if optimus is on (solved)
1 messages · Page 1 of 1 (latest)
In order for DXGI to work, LS must run by default on the GPU connected to the monitor (this has no relation to the preferred GPU selection in the LS). When the iGPU isn't disabled, it is used to output image to the laptop screen, so LS should run on it by default. Typically setting LS to power saving in Windows does just that. This is Windows API limitation.
WGC doesn't have this limitation.
GDI should be used for pre DX era games only.
what was the cause of the issue?
