Myter om grafikkort og ydelse

Tom's Hardware ser på myter om grafikkort og ydelse.

"Aktiver eller deaktiver V-sync ?, 2GB er hurtigere end 1GB, Input lag betyder meget ? Grafikkort bliver langsommere når de bliver varmere ? Windows 8 æder 25% VRAM ?"

Dette er blot nogle af de spørgsmål/myter som Tom's Hardware har sat sig for at undersøge til bund. De vil se om der er hold i myterne og om de ting virkelig er noget der har en markant indflydelse og ikke blot er en pseudo effekt.

Der er flere interessante emner som der bliver observeret på bl.a det for tiden meget omtalte input lag ! har det virkelig så stor betydning og er det reelt noget man lægger mærke til.
En lille teaser for at læse deres i artikkel igennem er bl.a dette skema der viser reaktions tiden på visuel stimulus for F14 Tomcat jagerpiloter fra 1986.

"Human reaction times to visual inputs vary. According to a 1986 U.S. Navy study, the average F-14 fighter pilot reacted to a simple visual stimulus in an average of 223 ms. And it might not seem correct, but human beings actually react faster to sound than visual inputs. Reactions to auditory stimuli tend to be in the ~150 ms range. "

Omsat i praksis så betyder dette:

"Fortunately, no matter how poorly-configured your PC may be, it probably won't hit 200 ms of input lag. So, your personal reaction time remains the biggest influencer of how quickly your character responds in a game.

As differences in input lag increase, however, they increasingly do affect gameplay. Imagine a professional gamer with reflexes comparable to the best fighter pilots at 150 ms. A 50 ms slow-down in input means that person will be 30% slower (that's four frames on a 60 Hz display) than his competition. At the professional level, that's notable.

For mere mortals (including me; I scored 200 ms in the visual test linked above), and for anyone who would rather play Civilization V leisurely than Counter Strike 1.6 competitively, it’s an entirely different story; you can likely ignore input lag altogether."
