13.2b drivers solve Frame Latency problems. - Page 7

post #61 of 202
Can anyone help me clear up the mess in my understanding? Okay so to summarize the whole situation AMD is looking into frame latency. Obviously according to latest reports from TR they have done a good job, they seem to know the possible cause and how to tackle the problem as well. However , I have noticed that the current 13.1 only fix latency issues in certain games, not that(not sure about dx9/10 or was it 11 or a mixture - I'm on a crwppy phone ATM looking up on this slow phone is a hassle).

As I understand it, the upcoming complete (official) amd 13.2 beta which is to be released next week(?) Will come with a memory manager? Does that mean latency will be fixed generally or is it left to AMD to adjust EVERY game out there? Personally I'm even excited to see if we will have a fps increase. Anyone care to explajn? Also, what am I to understand under memory manager. I mean I know it the way memory is handled is being re written . Is that something we users can make adjustments to or is it a "passive skill" (nerd talk :-p)

The leaked 13.2 beta contained latency fixes for very sepcific games, not 13.1

Those fixes, along with others, will be in the 13.2 offical beta coming soon

The CGN memory manger is being written as we speak, and wont be in a release until at least march.

the new memory manager has been in development for a while. the QA (quality assurance) and release is being accelerated.

http://techreport.com/news/24136/driver-software-to-be-tweaked-to-reduce-radeon-frame-latencies-in-series-of-updates

The most intriguing revelation in Baumann's correspondence, though, concerns one specific technical contributor to the frame latency problems on HD 7000-series Radeons based on the GCN architecture: less-than-optimal memory management in software.

"Additionally, when we switched from the old VLIW architecture to the GCN core there was a significant updates to all parts of the driver was needed – although not really spoken about the entire memory management on GCN is different to prior GPU's and the initial software management for that was primarily driven by schedule and in the meantime we've been rewriting it again and we have discovered that the new version has also improved frame latency in a number of cases so we are accelerating the QA and implementation of that. "

So what we have in Cat 13.2 is a series of targeted tweaks that appear to work quite well for the games in question. However, Dodd says additional improvements are coming down the pike, including a rewrite of the software memory manager for GPUs based on the Graphics Core Next architecture that should bring a more general improvement:

"The driver does not yet contain the new video memory manager. Our intention is release a new driver in a few weeks, which does include the new Video memory manager, which will help resolve latency issues for DX11/DX10 applications. "

given that the new memory manager driver is a few weeks away mostly a feb launch can be expected.

regardless of the comment in that article, i would say february is overly optimistic.

It will not be in 13.2 beta which is technically February.

"Andrew Dodd, AMD's Catalyst guru, tells us a variant of the Catalyst 13.2 beta driver we tested will be released via AMD's website next week."

13.2 beta is due this week or atmost next week.

is it safe to assume that he means all dx10/11 games will be fixed? meaning they won't have to tinker around with the code to fix latency every time a game is released?

yeah its not some game specific optimization. the new memory manager would benefit all DX 11 /10 games (especially those which currently have frame latency issues) and would not be game specific.

i was referring specifically to the memory manager re-write.

Tech reports did not have a new memory manager in their drivers, just game specific targeted tweaks.

Nor will our 13.2beta.

Don't be angry because you ran out of arguments, I've always seen raghu using empirical facts and that's what he did here.
Haha, arguments for what? It's not his facts I have a problem with, it's the fact that he repeats them verbatim over and over and over and over and over

its because there are people who need to be reminded over and over and over and over about these facts. i am not talking about you though. because my post was to a person who was talking about a HD 7950 at 800 mhz being on par with GTX 660 Ti. the HD 7950 boost has been available since aug 2012. AMD has stopped manufacturing HD 7950 at 800 mhz since early Q3. if a user is buying a HD 7950 at 800 mhz it means he is buying older inventory. so the user needs to get a really good price to even consider one because at the same price you would always pick the HD 7950 boost. also the OC headroom is one of the main reasons a person would pick a stock HD 7950 at 800 mhz over a GTX 660 Ti. even though they might be on par at stock once overclocked its a no contest. an average overclock of 1.05 Ghz would put the HD 7950 in fact faster than stock GTX 680 and much ahead of any average clocking GTX 660 Ti. thumb.gif
