I'm using the "+menu_advanced_AllowAllSettings 1" for DOOM (steam launch options) and it allows Nightmare
to be selected and used for Texturing and Shadows quality settings.
OVERCLOCKED: 1400/6000 @ 1150mV
DRIVER: 364.91 BETA
GAME SETTINGS: MAXED. However, when running both available settings on Nightmare
, it can sometimes cause the game to crash and exit randomly as video memory climbs 4GB+ in certain areas. So that warning about the 5GB video memory, yeahhhhhhhhh... truth!
The game runs flawlessly (DAF BTW) and is averaging over 60 FPS almost everywhere with the settings above.
Here are some quick screenshots (nothing special):
