Virtual V-sync

[Tempered81]

So the z77 panther point motherboards that go with ivy bridge 3770k's claim to have this amazing new graphics technology.

There's actually 2 cool points. It can use the onboard integrated HD4000 Ivy graphics to boost your discreet graphics card power (vendor agnostic).

But the real kicker is this: "Virtual V-sync". They let you unlock the refresh rate lock of v-sync (so you arent locked at 60,70,85, or 120fps or whatever your panels refresh is) but you get to keep the benefits of v-sync by having a smooth image with NO TEARING. Sounds too good to be true, and its from your old friend Lucid. hehe.

Any thoughts on this "Virtual vsync"? Would love to have zero tearing at 100 fps on my 60hz display.

Thats pretty cool. To be fair though, why run a 60hz monitor? Get 120hz... Makes more sense. Win. Why disgard 40 fps of performance so you can run smoother at lower fps cap that is less smooth to begin with........

 

[Anarchist420]

Didn't nvidia's triple buffering under opengl do the same thing?

Does it add the same amount of lag as normal vsync?

Why? So your video card can consume more power?

Rephrase that to no tearing with vsync off. Jag whats your take on this?

My take is you can't see nor feel more than 60 frames if your screen is refreshing at 60 Hz, so why make your GPU work harder than it has to?

 

[Cerb]

What's the point? Rather, what's so special about it that V-sync and triple buffering don't do? The signal to your monitor is still only giving your 60 FPS.

 

[MrK6]

I run a render cap of 60FPS unless I'm benchmarking. It saves power and improves image quality without any input lag or sudden framerate drops from vsync.

 

[JimmiG]

I always use Triple Buffering whenever possible. That way, you aren't limited to just 60, 30 or 15 FPS.

vsync has massive input lag, even true triple buffering is a degree slower than no vsync, if this can be faster than all forms of vsync it might be worth the option

most games do not naturally support true triple buffering

render caps will still have some degree of input lag relative to nothing at all, as well as the potential for tearing

granted, anyone truly serious about input lag will want to invest in a higher end 120Hz LCD or even be using a trusty old CRT and will be running as high a refresh rate and frame rate as possible

that all being said I have very little faith in this technology to do anything tangibly good or better than what experienced users can already do on their own. Their HyperPerformance technology is a joke as it implies you're going to be pairing a discrete GPU no more powerful than Ivy's iGPU.

and as a rather competitive gamer, I wouldn't even trust the switchable graphics to not add some degree of input lag, although that is the one feature that has the most potential as it should mean you could power down your very beefy dedicated GPUs...granted, that's not much of a issue these days as even the beefiest modern GPUs are now scaling down to draw next to nothing when they're not being pushed.

All you have to do is limit your frame rate a tiny bit below the refresh rate (59) to trick your driver into thinking the GPU is not fast enough to render ahead, and it will not fill the back buffers with pre-rendered frames. That virtually eliminates all input lag and you can enjoy ~60fps performance with no tearing and no input lag. That's much better than their crappy innovation which would raise both my power bill and my room temperature.

power bill savings is a shell of an argument

It's a perfectly valid argument when it gives you zero improvement... it's called a waste.

Ah, the noob in me has never heard of this method. Does that mean the GPU only renders 59 frames or do you still get 60?

It's probably because I'm a moron, and I don't play high octane FPS any more, but how severe is input lag when using v-synch + triple buffer (via in-game when supported?) Is it really an issue?

No, it only renders 59. It's important that you're rendering less than your refresh rate for it to work. Can't really say how severe it is, it varies between game engines. It can go from slightly noticeable to very noticeable. The trend I see is that the older the engine is the more severe the input lag seems to be, probably due to poor triple buffering implementation.

Thanks for that tip, I will be experimenting tomorrow

Would this apply to a 120hz monitor? Would I use 119? Or at that point, it really doesn't matter?

Yes it works for 120Hz as well, you would use 119. At 120Hz however, you're already experiencing half the input lag you would at 60Hz, so it's up to you whether it's discernible or not. Try and feel for yourself.

That's what D3DOverrider is for .

I have the MSI 80 series with the new Virtual V-sync . Man its is great . Its = in value to a new highend GPU . The Virtual V-sync great higher than 60fps without tearing . and the performance mode . I can't believe what fraps is telling me . This is like magic .

I can't say much but here is a story about it . Just so ya know the MSI M/Bs are the ones ya really want with this feature. + ya get thunderbolt .

If they’re still synching to the refresh rate with an uncapped framerate, they must be dropping the excess frames.

Interestingly enough triple buffering will also drop frames in the fringe cases where the framerate gets very low, so this is like the opposite.

 

[Nemesis 1]

With virtual -v sync. you get higher than 60 FPS without tearing. Online gaming this will be big . Than switch on the Lucid performance mode and from a NV 560 ti you get AMD 7970 performance . Thats right you read that right . This is the biggest thing to come around in years.

Big for online gaming? I don’t think so.

Not really. They promised automatic scaling and that application specific optimizations wouldn’t be needed, but that wasn’t the case.

All Hydra does is increases your ability to mix-and-match boards for multi-GPU, which I guess could be useful to some. But it’s hardly earth-shattering.

 

[Nemesis 1]

Thats not true. I have the M/B up and running with the software . In lucid performance mode . Its like running sli. Have a read . I have a video also but someone else can post it . If they find it . I will wait for more post like yours befor I link to it. See how I am.

I always run with a framerate cap to keep framerates in check, otherwise in many games you wind up with your cards cranking out 100+FPS and churning out lots of heat and noise. Why do that when your monitor can only display 60 ? Once there are 120hz monitors with quality panels I would want to use there will be some use going over 60fps for me.

If this actually does what it says, it will be awesome, sounds too good to be true though. Also puzzled as to how it will do this if your monitor is plugged into your video card and not the output video port of the motherboard ?

Heres a video I can't stand the mis information any longer.
