Nvidia 2013 tech day ? OptiX sdk

[DavidGraham]

I am interested in PhysX Flex perfomance improvements.

FleX is not a performance improvement , it's a technical upgrade to PhysX just like ApeX before it, basically PhysX worked like this :
-At first PhysX provided limited cloth, destruction and particle simulations, then PhysX was enhanced with ApeX, which greatly expanded cloth simulations , introduced turbulence and better fluid simulations , increased the number of particles .. etc. Now FleX will introduce rigid body interactions, enhanced fluid simulations and possibly other features.

Performance improvements will be achieved by using PhysX SDK 3.x , which is heavily multi-threaded, most games have been using SDK 2.8.4 ,which doesn't work well with mutli-cores, however some recent games have opted for the latest SDK versions, like Bioshock Infinite ,Planet Side 2 and Warframe. Unreal Engine 4 will also natively support version 3 .

Well Bioshock Infinite is out, does it support sdk 3.0 ?
edit : it does, but not on my pc amd user

Why would being an AMD user matter? I don't think bioshock infinite even uses GPU PhysX.

 

[DavidGraham]

Bioshock only uses CPU physx ..

very interesting G-Sync

Bleh. Needs a new monitor. I'm more interested in game stream but it looks like that requires an Ethernet connection and a Shield. I can probably figure out the Ethernet bit but I have no interest in Shield in its current form.

What I want is PC->console->TV and Controller->console. Might have to wait for a cheap steam box.

cut Might have to wait for a cheap steam box.

yes...or a mini pc build by yourself and steamos

g-sync is interesting in perspective, when i will decide to change my monitor and buy an nvidia card :smile:

Can someone explain G-Sync ?

its cool tech but expensive. I'm not ready to buy 3 new monitors for it. Not when I can get 2 more monitors for my current set up and go 5x1 eyefinity !

An interesting point concerning G-Sync :

Indeed, traditional bar-chart driven GPU reviews could almost become somewhat meaningless - even if an AMD card outperforms an Nvidia competitor by 10 or 15 per cent, if it doesn't have G-Sync, the problems with tearing and judder will still be there, but they won't be on what traditional metrics will tell you is the weaker card. By extension, we can also foresee that this will be a problem for Nvidia too - if the perceptual difference between, say, 45fps and 52fps, is ironed out to a great extent by G-Sync, we wonder if there will be enough differentiation in the product line-up to make the more expensive offering worth the additional premium. What is needed here is more testing on the impact of frame-rate differences on the gameplay experience - G-Sync may solve tearing and stuttering issues, but it can't address input lag, which does tend to be impacted by lower frame-rates (though this too can be addressed to a certain extent by developers).

very interesting and complete article, thanx for sharing

whats the other tech nvidia has that makes a lcd look like a crt ?

Well, i like the idea, i like what it can do, but i really need see it in practice, for see what difference it can bring , and what monitor will support it.

I m looking for a 30" - 2560x1600 monitor or 27" 2560x1440, if it is only available on the 24-27" 144hz - 1080p TN,... Well its a choice to do..

Well, i like the idea, i like what it can do, but i really need see it in practice, for see what difference it can bring really, and what monitor will support it.

Even if i could play many games at 100+fps, i just set in general v-sync at 60 and use in some case, the Radeon Pro "sync" settings.

I m looking for a 30" - 2560x1600 monitor or 27" 2560x1440, if it is only available on the 24-27" 144hz - 1080p TN,... Well its a choice to do..

from that article:

From there, the next reasonable question is to what extent higher-resolution monitors are invited to the party - we saw 1080p displays at Nvidia's event, but having moved onto 2560x1440 and recently sampled 4K, we really want to see the technology rolled out onto more pixel-rich displays. This is very likely to happen: sustaining that even, consistent performance on higher-resolution displays is a massive challenge, and G-Sync technology will prove even more advantageous there than it is with the 1080p displays we saw.

we'll see, i'm potentially interested at 1440p or 4k monitors with g-sync, or at least a module for my actual monitor (when i decide to buy an nvidia card )
