Refract uses the uDesktopDuplication library to capture the screen at high frame rates. As noted by the author, some hardware is not supported by Desktop Duplication:

hecomi/uDesktopDuplication#30

If your system has the ability to disable the on-chip (non-discreet) GPU, give that a try.

If you have an nVidia graphics card and have nVidia Control Panel installed, you may be able to force Refract to run on the on-chip (non-discreet) GPU. Performance won't be great, but it could work.

Ideally Refract would get frames directly from the game rather than from screen scraping. This is a feature that is being looked into with help from other community members, but we don't have anything yet to announce on this.

i'm having same issue. funny thing is that it worked somehow last night, and i played around with it for a while. can't replicate what made it work now though, I'm restarting holoplay service, switching from integrated graphics to nvidia, restarting refract. bit of a mystery!
