Comment Yay! (Score 1) 772

After accounting for the euro to dollar conversion (and discounting different taxes and cost of living because I'm tired) Science(*) says I should be about 90% happy!

Yay!

(*) and not any kind of Science, Princeton Science!

Comment Maybe that's the point (Score 1) 1268

Maybe they deliberately used non-standard notation to see if the students could come up with a sensible interpretation of the problem.

Yes, writing "4+3+2=( )+2" when you mean "solve 4+3+2=x+2" is weird, but interpreting "4+3+2=( )+2" as "compute 4+3+2, then add 2 to the result" (which the example of a wrong answer given in TFA) probably means you don't understand what an equal sign is.

First, I'd like to see the science that proves that 24 fps is enough for everyone.

While I agree that insisting on 120fps when your monitor can only display 50 is silly, I actually did a double blind test on a 120Hz monitor and I could definitely tell the difference between stable 60fps and stable 120fps.

Maybe some people can't tell the difference. Most people who can probably don't care. But I know I can tell and I do care.

Also, games and movies are different. In a movie, there's motion blur which helps a lot. 24fps in movies is okay most of the time. But to do motion blur in a game you need to increase latency by a few frames and low latency is more important than smoothness in a fast-paced game.

Comment 3D NOT the same as color/sound (Score 1) 521

Directors can (and do) shut the sound for a scene in a movie with sound, if they think that scene is better with no sound. They can put black & white shots in the middle of a color movie. Even for individual shots it's not binary: you can have slightly softer sound/music for this scene, slightly less saturated colors for that one, etc.

Not so with 3D. The movie is entirely 3D, or it's entirely 2D. No 2.63D here and 2.12D there either.

Plus, for the shots where 3D doesn't add anything, it usually is a nuisance (eg. if you try to focus on blurry background) and I don't think many stories worth telling can make good use of 3D in every single shot.

I agree with your post, if some software makes your hardware overheat, it's a hardware problem. I have a minor nitpick though.

I fail to see how rendering a scene at a high framerate would be any more challenging than rendering a complex scene at a lower frame rate. Remember that the hardware either is or is not in use. The ROPs, the shaders, etc. It isn't like there is some magic thing about a simple scene that makes a card work extra hard or something.

Actually, there can be such a magic thing.

An ideal transistor will draw current only when changing state (a transistor is basically a more complex version of a capacitor, changing state is like (dis)charging). An actual transistor leaks current even when idle, but still draws more than idle to change its state. So, if a computation changes the states of more transistors, it will draw more current (and generate more heat).

My Computer Hardware teacher at school told us a story about some project he'd work on, where they cut by a fair amount the power consumption of a hearing aid (and thus increased the battery life) just by changing the representation of a variable from 2's complement to sign-magnitude. The device was updating very often some value that never changed much but was always close to zero so it changed sign a lot. With 2's-complement almost all the bits change with each sign change. With sign-magnitude, only the sign bit and the lower bits change, which means less transistors changing state thus less current drawn.

Maybe the cut-scenes in SC2 are exposing a use case the GPU engineers didn't thought of, or didn't think was realistic, when they computed the TDP, making the cards overheat in this very particular case.

But even in that case, it still isn't SC2's fault. And yeah, more probably it's just inadequate cooling/PSU/whatever.
