Are we doing this?
Dear god we're gonna do this.
I mean the answer is pretty straight forward to me. There's a trade-off, but I definitely care more about having a stable frame-rate than a game running at a super high resolution.
THAT BEING SAID...
There are certain types of games where I'd rather have them run at 30 frames per second instead of 60 for extra detail. A game like, say, Uncharted 4. Story driven games.
But fighters? Your Street Fighters and your Mortal Kombats and whatnot. It's pretty much essential that they run smoothly.
