how do I add the configs? they are being stubborn... LOL!!!

And now I got the game running again after trying a few things out but the sound is still echoing... I dropped to an older version to see if that was the problem but it didn't. I had to mess with the settings in the launcher, which is weird because I set them high and then knocked them back to where they were and I'm not getting the low memory any more... BUT on occassion the game will crash out of the blue... Sometimes while spawning in other times while I am just moving astronaut mode from one location to another... I don't know what's up with the game and my brain is pounding from it...
And one last thing I don't know what the checker is talking about I have an HP with Intel everything and last known the graphics card handles HD really well... as I said up until a today the game was fine what could of possibly changed that would of caused me to have crashes and other problems???
