Let's see--over $40,000,000 in development costs. (That was around a year ago, so probably at least another million on that.)
Now, bronze costs $50. So... they'd have to sell approximately one million copies to break even. Except WAIT, that's not true. Because we're ignoring Vivendi...
This is why DM isn't a very popular gameplay mode (in general) right now. It's just not that fun.
It's also why so many people said "who cares if they give us HL2DM".
Bunny hopping isn't just jumping repeatedly. It's jumping AND STRAFING in such a manner as to increase your speed astromomically. (To the point it looks like hacking if you don't know what's going on.) This is sometimes also referred to as "strafe jumping".
Having played RF and RFII, the destructible walls were limited and added almost nothing to gameplay. The physics in HL2 added far more to open gameplay.
Never ask this question again. Any time you think, "Has anyone emailed Valve about...?" the answer is, "Yes -- about a million times."
The correct question is, "Has anyone posted an answer from Vavle about ....?" If no one has, go ahead and ask them again. :)
No. If you have a 120 MHz refresh and your computer is managing only 15 frames per second, vsync is not limiting you at all. So, turning off vsync MAY improve your FPS.
Filtering is a method of making the textures scale appropriately with distance. Again, higher is better, but it'll cost...
Short version:
Antialiasing removes jaggies. Turn it up as high as your graphics card can handle. (Turning it higher will lower your framerate.)
Vertical sync makes the monitor refresh sync with the redraw of the scene. Turning it off may give higher framerate but you may notice...
