It looks like you can run Toribash fine with all of the fancy settings, so you should resize your Toribash window as well. You can change it in one of the options menus inside the game, or just type /re 1280 720 while in-game. That will make your videos come out in 720p HD.
You can press the ESC button on your keyboard twice to get rid of the GAME button in-game.
Also /opt hud 0 get's rid of the name, score, and timer. Not sure if you took out the names and score on purpose, but left the timer. Type /opt hud 1 to get all of that information back on your screen.
