Your using vsync?
Looks like its a good time to CF my 7970s
I don't think that it will be a "Crossfire related only" fix...if they change the way (and time) the frames are drawn on the screen, the single card would benefit of it, too. Unless they won't lock the algorithm in single mode, but I would not understand why doing something like that, when they say that it will be just an option, disabled at default. And not only, also the V-sync will work better...with a setup that has good frame times in the first place. It's also possible that the Vsync will be less used and left off, 'cause the animation could be smoother, despite the tearing...it depends by "personal discomfort" IMHO the stuttering or frame latency is noticeable even with single card (not in every game, but often prominent)...own a Crossfire 7850 2GB and I am sure that is a drivers related problem, not about the card power...for sure
It is noticeable in every game on single card.I can spot it and i spotted it in thier videos at 720p.
I was seriously depressed when i got my computer in my sig compared to my old one.I have 20% judder like in the video on all my games and i see it no matter where i go as im very sensitive to it and it ruins gaming for me to be honest.I Dare not try dual cards so whatever fix is needed is it needed for single card as much as it is needed for crossfire/sli.
Vsync just is not an option due to the terrible tearing you get with it off.With vsync on with a constant 16.7ms im going from 60fps levels of motion to 30fps levels of motion due to frames going from 16.7-30ms due to vsync.I could never figure this out but im telling you that PCP are gods for getting this into the spotlight.
And even better i can finally due to thier videos see what 60 frame per second looks like with vsync off and again its not smooth enough.I can spot judder at 60fps so i guess i really do need to make the jump to 120hz soon.
At least at 120hz u can use vsync and not worry that much.Sure u will still have frame time being doubled but your going from 8ms to 16ms instead of 16.7ms to 30ms resulting in at worst 60fps levels of motion versus 30fps frames of motion im getting now with a constant 60fps vsync.
And also why am i now getting frame skipping on 58-59fps? Is this due to them tweaking vsync? I literally go into judder city at 58fps.This never used to happen on my old pc yet its happening now on all my games.I guess not that much of a deal as i try whenever posible to not drop to 59fps but still mega annoying.For now gamings on hold for me.
4k is coming and perhaps vsync might die.Things are actually looking up!
gtx 580 is your old card? what now?
What you see in the movie is clearly visible to the naked eye.
I never use vsync.. i hate it.
in my opinion at the moment without vsync is even more annoying...
If your card is able to do a steady 60fps with vsync on, I don't understand why you hate it...but is legit
AMD single-GPU frame pacing fixed; crossfire fix expected in ~90 days
AMD single-GPU frame pacing fixed; crossfire fix expected in ~90 days
Today the @AMDRadeon twitter account hosted a Q&A session, and of course the frame pacing issue came up:
@AMDRadeon - We're anticipating a beta release in the June/July timeframe. I should note that single-GPU pacing is already fixed. ^RH
Internally, AMD are conflicted on the best way to solve the issue - after all, the driver is doing what the game engine is requesting, with regards to timing of present calls. Placing an additional latency into the game engine to smooth the animation rate could be construed as adversely affecting the original artists vision of play, and may have adverse effects on competitive players.
AMD's response shows they are listening to press and fan feedback on what's expected from them, even if it goes against something previously espoused as untouchable - don't mess with the game experience.
As AMD APU's and GPU's become the defacto game development platform, hopefully we can expect to see AMD's developer relations teams working to get smoother gameplay on AMD hardware out of the box and inside the game engine, instead of patched in after the fact.
Can't wait to see what xfire users here make of this driver. This will be of much more interest as everyone asked here seems to be in agreement that things feel and look fine as they are at the moment. The bit in the bold is part that i wouldn't want if things are already smooth. However if stutter is a problem in a specific game then this will be a welcome addition. Either way i suppose its nice to have the option to choose which one you want.
already fixed, where...? in the new release? in my opinion is not "already" completely fixed...if the approach to the issue there has never been.
in a way, they're also blaming the game developers? maybe right in some cases, but I don't see any problem if someone fixes the frame time...if there is stuttering, there is...so they could create an interface on per game basis, a game profile...anyway i see the videos by pcper and there are many new games, not only one or two...always a developer fault? crytek, ubisoft, ea, dice & co. ? anyone?
again, don't understand how to ruin the experience if the frame latency is fixed...better 60fps to 55 drop or 60 to 59 or a steady (if vsync on at 60hz) 60...58,...and so on? or if vsync off, try to limit or completely remove any excessive frame drop?
really hopefully...for every game??? i think that's very difficult...this is not a joint work, it's enough to follow guidelines, which it means that the frame time has to be good since the beginning...so the developer can test & debug under the best smooth conditions...
I never have tearing issues with vsync off. Maybe due to my 120hz monitor. I hate vsync mostly due to the input lag or other weird issues i sometimes get, besides i dont need it since i never get tears.
weird, it should help vsync but without... tearing should be visible even below the refresh rate...are you sure or that little perceived tearing does not bother you? what monitor you have?
Latency has not really changed for me on single gpu even after this supposed fix. Its always been excellent, its just been improved so it now sits just behind a titan is all. These sort of changes can't really be felt though, how can you improve on already smooth?
I didn't see anything about them blaming developers. I agree with what they say, adding latency to certain games is not what i would want personally playing twitch shooters. This is what they mean when they say it could hamper the experience.
If the game in question is not smooth then i can see it being a nice benefit and definitely an option which the user should have. Either way should not be forced in my opinion and having the option to pick from a increased latency or a faster response time is a good thing.
If you have latency issues with a single gpu then i would look closer to home for the fix to your problem.
For single gpu performance the 7970 is smoother than its competitor the gtx680 according to fcat results. With this in mind it is completely fixed. I think amd had this fixed in the 13.1 or 13.3 beta drivers.
so is this only going to work for 7000 series crossfire?
sometimes i notice a frame drop, even if single, with vsync off. My dlpc latency is good, mid 30µs so this can't be an issue...: i'm using Radeonpro with OSD. That's really limited compared to crossfire, but can't say that is completely absent...and not able to play without vsync at 60hz, maybe i'm more sensible to this "stuttering and tearing" but maybe with these new drivers i'll do without, hope to can test soon...
look in the sig.. a samsung s950. And no i do not like tearing.. it bothers me.
sounds promising think i will move back to AMD is it all goes well.
Any sign of these prototype drivers yet?
Should be sometime this month hopefully. I wonder if they will bring it in around the E3 announcement.
Good stuff. The videos look very good with it running.
