SLI- Whys it not 2x as fast?

[Durzel]

if it was that simple, why would nvidia include a function to show how much of the screen each card is rendering?

As you can see, when the screen is full of complex items (top pic) then its 50/50... but when there is more calculations to be done rendering the bottom half, the split is 70/30 (2nd pic). It can only work out how much each card should render by calculating it - hense the complexity :}

That's really clever!

I'm quite sure that alternate frame rendering is also done with SLi (not at the same time as split frame). I seem to recall reading something about it being technically superior and giving better frame rates in most games than split frame, but suffering from latency issues of a few miliseconds which effectively make it usless in first person shooter games....which by chance are also generally the most graphically demanding.

Final year exams.....

Already? Aint got mine till late may / early june.... writing my 25k thesis aint stopped me spammin like a hoe. Cant let down uncle ATI just cos I got education commitments

 

[man_from_uncle]

25k words? At Nottingham? What are you studying? (A Masters I assume, but that's still more words than mine)

 

[Goksly]

Software Engineering. Doesnt have to be 25k words.... but guide line page count is around 85 pages and when I handed in almost 95page I was told there are still some gaps to fill. fs ;p

Haha. That made me laugh out loud

Didn't know Nottingham did post grad Software Engineering. Good for you mate. I suppose you plan to be practical and actually DO something with your masters rather than become a professional scholar (or full time-long term student as they are also called).

ew no im not doing a masters mate - this a bach of science micky mouse thing :} cant afford to miss out on any more money years - so going into the industry after I get me piece of paper.
