I've tried various versions, 1.4, 1.5 + others but the game either just stays normal or crashes upon starting.
I know it's a dx8 game and so used enbconvertor_dx8_dx9_v0035 like others have, plus to turn off antialiasing.
The log says:
full path: W:\Games\OutRun 2006 Coast 2 Coast\

initialising shader environment
Any ideas?
