Everything is Black

Hello Hunters, so i wanted to replay manhunt, but almost everything is turned black(i installed ManhuntFixer, nothing happened). Is there a way to fix this?

Edit: I fixed this issue. So, in order to fix this, head to the settings>system>display>graphics>manhunt>power saving(integrated graphics)
