a nice article on GPU testing

It's over on the Tech Report, and speaks to a new consideration for benchmarking GPUs versus the general FPS performance testing used by the site now. A good read: http://techreport.com/articles.x/21516
I hope some find it useful.

SLI/ Crossfire needs to have two SLAVE GPU's on one card, doing the AFR work, which spits that out to the MAIN GPU on a second card which the monitor connects to.
Basically, the slave does the work and the main puts it together

Interesting article though

Very nice article.
So maybe an explanation for microstutters people with comps that I would consider much more pwerful than mine were/are experiencing? I have to say I have no microstuttering in flight at all.

Another point pertaining to the game, one suspicion seems to be coming up. The game maybe benefiting much more from faster cpu's than from increased graphics power, according to my own experience with temporary mild overclocking (just ordered a proper cooling solution to overclock on a more permanent basis) and some other posts I read.

Nice, long, thoughtful article.

I saw it via slashdot yesterday or the day before.

It does suggest to me that there's something going on that could be fixed in graphics cards that might make more improvement than simple increased FPS.

Ned, micro-stutters are a big mystery to me. I thought it was a frame-rendering issue at one time. Then another time I thought it was a bottleneck elsewhere(?) holding up a data flow. So maybe it's a combination of things. We are always chasing bottlenecks as we find them: CPU, GPU, memory,etc.

I sent the author of the article a link to this site, and this "Performance" thread. I suggested he use the sim for GPU testing. He replied he'd give it some thought, and said he found the site interesting. [edited to remove certain content]
