Eeee... a kako smo samo ovde bili napljuvani ja i jos neki da trolujemo, da izmisljamo, da lazemo, varamo, a evo sada i sam AMD priznaje da imaju problem.

To se resava podesavanjem queue size opcije u ATT-u ili RP-u. Ali ako stvarno postoji taj problem sa novim karticama i nameravaju da ga rese driverom, onda ne bi bilo lose da ubace queue size podesavanje i jos neke opcije iz ATT-a ili RP-a u CCC.. To bi bila najbolja varijanta imo.The way this is usually done is by observing "back-pressure" from the pipeline. If you pick a static number of frames that you are willing to buffer up at the start of the rendering pipeline (usually 1-3), when there's no more space in the queue you simply halt the game and wait until space is available. Then, assuming that pipeline is running in a relatively steady state, the game can time how long it takes from the point that it fills the queue to the point where another slot opens up to get the rate of output of the pipeline. This is what pretty much every game does, and this is the same timing that FRAPS is measuring. GPU vendors like this strategy because it ensures that the GPU usually has more work waiting in the queue and thus will run at full throughput and show high frames per second numbers.
^tu nigde ne pise da u AMD-u priznaju da imaju problem i da ce ga resiti novim driverom... Citira se i objasnjava isti test sa pocetka teme, a da se jos niko sa nekom 7000 karticom nije javio i potvrdio taj lag. Kako je opisano, lag bi trebao da se pojavi svakih nekoliko sekundi... znaci klizi pa zapne.

There is no one single thing for, its all over the place - the app, the driver, allocations of memory, CPU thread priorities, etc., etc. I believe some of the latency with BL2 was, in fact, simply due to the size of one of the buffers; a tweak to is has improved it significantly (a CAP is in the works).
While I like the scientific application of the analysis some work does need to be done to understand the thresholds. While I cannot deny there are spikes (the driver team have spent a lot of time analyzing where they are coming from and smoothing them out!), I can't say that in the games I've played they have been noticeable, likewise I do not see end user feedback for this type of issue (except, maybe outside of a few known problem titles).
nVIDIA je imala isti problem u prošloj generaciji, u vreme GTX560Ti dijagrami su izgledali još lošije nego što to danas AMD karte pokazuju.
Ne da je popravio, nego je manje-više potpuno sredio stvar rekao bih... Od početka je delovalo kao da je stvar u drajverima a ne u hardveru, tako da se nisam mnogo ni brinuo, bilo je samo pitanje vremena kada će AMD da reši problem, i evo rešio je ekspresno!
