3d Vision and SLI not working correctly for ASUS rog swift pg278q.

[quote="Pirateguybrush"]Oh wow, you're getting 3 for surround? That's...insane, and not in a good way, IMO. There isn't a GPU around that's capable of driving one of these displays in 3D with high detail settings on newer games, even in SLI.

I do have 3x GTX 980's in Tri-SLI, so I'm about as prepared as anyone is going to be. I do realize this is a super exotic setup, and there is a good chance it won't even work.

3 and 4-way SLI has pretty minimal benefits in most games, even in 3D.

[quote="VultureX"]It's also such a shame that basically for each game a shader hacker has to make it work properly. If they stop then we are all doomed :( But at 1440p 3D vision really is a blast when it works. It adds a whole new dimension to gaming. It has much better quality than cinema movie 3D. This monitor is really great too in that respect. I bought two 970's so I could have some fun @ 1440p, but now I can only use one card. So I have to skip on the more demanding games for now :( I'm not too fond of the Oculus, although I haven't tried the latest DK2. The first version was kind of low res and I had the idea that I could creater far greater intenser popout effect with the 3d vision. It's such a shame that this isn't better supported[/quote] Yea, 1440p is a huge upgrade for 3d. Diablo 3 is like a whole new game! Ditto for Relic's Warhammer 40,000 and Company of Heroes. Any game with a ton of small details in it that just wash out at 1080p are real stunners in 1440p. I haven't even tried the 3d games I know haven't got a prayer without SLI like Far Cry, Assassins Creed, or Metro. Yea if you didn't like DK1, DK2 isn't much of an upgrade in terms of resolution. What they added in pixel density, I feel like they lost it in pixel structure. That said, positional tracking is absolutely amazing in regards to getting rid of motion sickness. If you have a game with a gui specifically designed to be readable in DK2 (Not Elite Dangerous) like Minecrift or Live for Speed, you really do get an amazing experience. Don't even bother playing anything that doesn't run at 75hz though, that is a recipe for illness :P

As far a G-sync 144hz goes at least that is working as advertised (even with sli on!). I don't use it a ton because I'm not that into 2d gaming, but for Red Faction Guerrilla where fps cuts in half while buildings collapse, G-sync cannot be oversold for smoothing out those drops.

[quote="bo3b"]Question on this problem with the monitor and SLI. I have a G-Sync monitor, but not the Swift the ASUS VG248QE. I've found the monitor to be a bit of a pain in the ass. When I have it unused (unchecked in NVidia control panel) it will connect and disconnect every 15 minutes, even while playing games on my projector. When I boot, sometimes it takes over as primary screen, even when it was unchecked. Even the simplest thing, window dragging, is stuttery. Lots of freaky behavior, none of it wanted. I've found things to work a bit better when I disable (uncheck) everything in the control panel except for a single monitor that I'm presently using. Projector if gaming, old Dell for programming, DK2 if I really want to spend time jacking around with monitors and configs. (why in the holy hell did they rotate DK2 to portrait?) If you have other monitors connected it might be worth trying to go single monitor as an experiment. It seems to me that multi-monitor is just broken in current drivers. One other thought- these monitors require DisplayPort. Anybody have an alternate DisplayPort they can try to prove or disprove that as the piece? I think maybe my test disproves DisplayPort, because I can run 3D on recent driver of 344.11. [/quote] I always have any monitor I'm not currently using unplugged. The only time I actually have 2 plugged in is when I'm on DK2, as it is very very difficult to see the ole 2d desktop in dk2. Yea, the whole portrait thing drives me NUTTO on DK2. Personally I think it may be responsible for a ton of the issues they are having with it. Because of the portrait issue, you are no longer able to use clone mode, because a rotated 1080p screen will not clone with a "normal" 1080p screen without losing the 75hz option from dk2. So that leaves you with an extended desktop onto dk2, which causes everything from stuttering to all out failure when you try and go fullscreen on it. Your other option is setting dk2 as your main screen and squinting into it to try and find your mouse pointer. (this is what I do currently) As far as I know, the "direct to rift" mode has never worked for anything beyond the config tool's desk demo (boy does that demo work great though :). What do you mean by alt displayport? Different cable or different port on card? As far as any stuttering or judder related to G-sync, I have none, G-sync is the one high point for the pg278q so far. All refresh rates are smooth for 2d, but I lose brightness in 80hz 100hz and 120hz. I only have full brightness at 60hz and 144hz. Wierd.

As far a G-sync 144hz goes at least that is working as advertised (even with sli on!). I don't use it a ton because I'm not that into 2d gaming, but for Red Faction Guerrilla where fps cuts in half while buildings collapse, G-sync cannot be oversold for smoothing out those drops.

Have you got your NVidia 3D driver set to do 3D at all times, rather than just when fullscreen 3D programs are running? The screen could be flicking to 3D mode when 120hz is activated, which would also drop the brightness, although not by as much as ULMB mode.

Yeah, don't use 144Hz! There are many other problems with 144Hz than this! Just put it on 120Hz and leave everything else as is, especially over-drive.

I could be mistaken but I also don't think 3D Vision works at 144Hz, I believe it only works with 120Hz.

Unlike going from 60FPS to 120FPS, the difference between 120FPS asd 144FPS is indiscernible.



This is true. Nvidia 3D Vision on a monitor is 120hz only, 144hz isn't used and you get diminishing returns in 2d, although games running at near 144hz with Gsync are amazingly smooth.

Leave Overdrive to its default "normal" setting - if you set it to maximum it can cause overshoot, which I think is another term for ghosting or smearing on fast moving objects.

I've only used the ROG SWIFT on a single 980 so I haven't experienced the same issues with D3 or Trine 2.


I can't turn off 144hz because the screen is significantly dimmer at 120hz. Perhaps I have a setting wrong, ULMB mode appears to be always off, but I lose a ton of brightness at 120hz. I have overdrive on Normal also. My current theory is that the sli problem we are seeing is somehow due to the 144hz refresh rate, even though its not supposed to be used for 3d, as other monitors don't appear to have the issue.

[quote="InsaneInGame"]Thank you VultureX for the link. I just completed the survey form. So let us hope for nvidia to ressolve this issue fast. However, I have this gut feeling that "fast" is a little too optimistic. With a high enough feedback density, perhaps we might see a fix soon. I'm crossing my fingers. :)[/quote] Yep found this also. I've got a ROG Swift also and just bought a 3D Vision 2 kit, and it seems totally stuffed. I'm running 670 in SLIs. If the game still runs 3D Vision it now can't run without massive frame drops even in 1080p. Something I noticed - on my previous ASUS VG278H, I used Adaptive Vsync Half Refresh (in 120hz) which worked quite well despite in theory that it wouldn't. With 60fps being rendered per eye, Adaptive Half Refresh did not cap the maximum frame rate but applied to each framebuffer (eye) which is running at 60fps anyway and helped run it better minimum framerates as Adaptive Vsync can. Now if I try this same trick in say Batman Origins or Crysis 2 in 3D Vision now (in 1080p) something became obvious - I get 30fps using the same setting now. It shows I'm in 120hz mode and Gsync is non active on the ASUS ROG. Turn 3D off and I get 60fps, whereas I should be getting 120fps in 2D mode. It seems like the fps has been capped to 60fps now - possibly as part of the 3D Compatibility Mode changes? Games I tried ... Chrome - confirmed the same. Does not display properlu at all with 3D enabled Trine 2 - confirmed the same issue. Displays the same image in both eyes essentially 2D Crysis 2 - In Vsync, it's now a stuttery mess, going from 15fps to 60fps. This was a unbudging 60fps previously. I think I tried the half refresh also showing 30fps Batman Origins - capped at 30fps @ half refresh and previously 60fps. With Vsync on, it's now a stuttery mess with the same frame fluctuations as Crysis 2. Will do some more tests tonight.

I am also having major problems with 780 sli and Rog Swift. But only after 337.88 driver. The Batman games are a stutter fest, even on the menu of Arkham Origins I have frame drops. If I go back to 337.88 the older games play perfectly. I asked a friend to try on his computer with an Asus 236H and after 337.88 e also has major frame drops on those games.
