Whenever I get a new game these days, it always takes me awhile to find just the right video/visual settings in the Options Menu. These days, we've got anisotrophic filtering this, ambient occlusion that, and my hernia also. Take Starcraft II for example, which is probably the most comparable game. There's like 20 different graphics settings in there, and my AMD video card software even has a few more. That's literally at least a hundred different possible combinations. It can take a good 5 or 10 minutes of ingame play tinkering just to find the right setting for your system, that also meets the individual's performance expectations (or what you are willing to accept). I personally hate having to experiment with this stuff live ingame (in any Mode). I heard that the Open Beta on April 21st probably won't have any tutorials or safe place to practice this stuff, just Multiplayer Games, so I have a suggestion.
I'd like to suggest an unplayable Test Map, or little shooting gallery the player can load up from the Options Screen at the Main Menu to find our desired settings without impacting the actual gameplay. Once the tiny 1 screen-wide level loads up, you would see a single Space Marine squad running back and forth across the screen shooting at a target dummy on the left, and then the right, and repeating this process over and over via scripted AI. At the top of the map could be a mountain or something, and at the bottom could be some varied terrain like trees or perhaps a basic structure. Here would be a safe place to get our video settings right without bonking a Multiplayer Game in Beta, or without messing up the "First Golden Hour of Gameplay" in Level 1 of the Campaign on full launch day. It's just not fun to have to deal with that stuff ingame, ever. So I think that this would be a great feature to hotfix in just in time for April 21st (it doesn't have to be pretty then), and maybe a more polished Shooting Gallery 2.0 by April 27/Full Launch Day.
