Why is AMD quiet about black screens on 290x?

Yes, that's right. I believe that is due to Sleeping Dogs not being very well optimised. I am sure if Kaap was to do a Sleeping Dogs comparison that the gains would be equally as beneficial on both cards mirroring his results (comparatively speaking).


IIRC the original point of it was to show differences between the 384bit and 512bit bus, and that with the low memory clocks the 512bit bus is barely stretching it's legs. If you're implying that the 290 would pull ahead in Sleeping Dogs which I'm thinking was your original point - I honestly don't think it would. Getting side tracked now so unless he can be bothered to run it it's a lost case lol.

No my original point was quite clear. Memory overclocking shows very little gain in most games. Sleeping dogs is different to most in that its able to saturate the bandwidth and thus shows decent gains from overclocking the memory.
 
It wasn't clear, as you said you wanted Kaap to use it. It wouldn't make a difference. I think also it needs to be made clear just how much is being applied in Extreme preset as it doesn't say. Doesn't matter anyway, Sleeping Dogs is ropey.

May be a case of using alternative versions of super sampling. Considering SD is UE3 I'd be willing to bet it's OGSSAA (order grid)

OGSSAA
-Very effective at eliminating aliasing
-Can improve scene and texture clarity, especially when used together with a low LoD Bias
-Relatively low performance loss
-OGSSAA works in Mass Effect, Dishonored, and other UE3 games with deferred lighting that are normally incompatible with sampled antialiasing
-Does not alter the size of HUD elements

SGSSAA
-Very effective at eliminating aliasing, but not quite as effective as OGSSAA
-Can improve scene and texture clarity, especially when used together with a low LoD Bias
-High performance loss
-SGSSAA also works in games that are normally incompatible with sampled antialiasing
-Does not alter the size of HUD elements
-Seems to retain a slightly sharper image than OGSSAA, in return for the higher performance cost

Its pretty clear if you read my first post. I've run tests to confirm that memory overclocking makes a big difference in Sleeping Dogs vs Tomb Raider. Sleeping dogs is well optimized and scales nicely in multi gpu. Its a well oiled machine, optimized well and certainly not ropey, at least on AMD GPU's. I've tried the whole Tahiti range on it, single and crossfire and now Hawaii single and crossfire so i have some experience regarding it and its performance.
 
I've documented this previously. In fact when Kaap did some memory clocking testing i tried (but failed) to get him to ditch Tomb Raider in his 290x Vs Titan memory clocking tests and use Sleeping Dogs because it actually benefits greatly from a memory overclock.

Ok. Nevermind, I must have imagined it when you referenced Kaaps testing methodology.

I do wonder about you sometimes Frosty. Read the person i quoted.

That 'theory of ours' was referring to mine and Kaaps posts (again read the thread) where we both say memory overclocking does very little in games.
 
MjFrosty said:
I did. You then went on to say you were going on about getting Kaap to change his testing method, which was irrelevant for the test in itself. End.

In the context of what was being discussed (See - memory overclock performance on gaming performance - Sleeping Dogs mentioned vs Other Games performance) it was extremely relevant.

Are you feeling ok Frosty? You having a bad day or something?
 
Don't get smarmy. It's dry and doesn't suit you. Kaaps test was to compare memory bus width, correct? I'm not sure what thread about memory scaling in games you're referring to. I don't recall ever seeing it.

I can see you're not going to let this drop easily are you lol.

I'm talking about what was being discussed in this thread prior to you coming in and getting your nose bent out of shape over god knows what. I mentioned Kaaps results because he tested at stock and overclocked, like i did. Only he tested Tomb Raider and i tested Sleeping Dogs. Sleeping Dogs is key here because someone mentioned it and hence how this started. Sinking in yet?
 
Kaaps test wasn't about individual scaling it was about memory bus width and benefits. It wasn't about one particular games gains.

You then compared some one else's comment on Sleeping Dogs VRAM clock gains to your own post in the memory bus thread.

Kaap posted in that thread that he was aware other games would show better gains, but it wasn't the intention of the thread.

Bye lol.

Its about showing how little games generally respond to memory overclocks. Sleeping Dogs being a rare example of a game that responds well to memory overclocks. As Kaap had done testing himself i referenced that as his testing showed that it made very little difference in Tomb Raider. Does not matter if he was testing bus speed or not, the outcome and end results are the same as he was testing memory at stock and then overclocked before documenting the results. Very little from memory overclocking in Tomb Raider, which comes back to the original point. Happy now?

I guess you're talking about yourself as I don't get those :D. You said you tried and (failed) to get him to use Sleeping Dogs, which wasn't necessary for the test he was conducting. End of story, I'm not debating Sleeping Dogs benefits better from VRAM clocks. I'm not going to go round in circles, just pointing out that you tugging on Kaaps arm trying to get him to try Sleeping Dogs defeated the object at the time, and in the context you were talking about. Now if you'll excuse me I've got some straggles to brush.

You do strike me as a man who has suffered from male pattern baldness and will now make sure others suffer for his own misfortune. ;)

:p:D me too, worked last night 9-7, got home this morning and thought i'd start moving everything from my Bitfenix ronin into my new Nzxt Phantom 630....only now finished it :(

worthwhile though, case is huge and plenty big enough for my little watercooling adventure.

Will do pal, watercooling will be next month though as funds are low at the moment.

I'll take a few pics in a bit and pop in the Cases section.

Hairs overrated. Thankfully I have the face of an angel and don't need to disguise my huge conk with greasy locks :D. It's a design choice more than genetic BTW ;)
