Nvidia Details 'Gameworks VR', Aims To Boost Virtual Reality Render Performance 20 20

An anonymous reader writes: In a guest article published to Road to VR, Nvidia graphics programmer Nathan Reed details Nvidia's 'Gameworks VR' initiative which the company says is designed to boost virtual reality render performance, including support for 'VR SLI' which will render one eye view per GPU for low latency stereoscopy. While many Gameworks VR features will be supported as far back as GeForce 6xx cards, the company's latest 'Maxwell' (9xx and Titan X) GPUs offer 'Multi-projection' which Reed says, 'enables us to very efficiently rasterize geometry into multiple viewports within a single render target at once... This better approximates the shading rate of the warped image that will eventually be displayed—in other words, it avoids rendering a ton of extra pixels that weren't going to make it to the display anyway, and gives you a substantial performance boost for no perceptible reduction in image quality.'

Yep, that's the bullshit argument that people were rolling out against same sex marriage all right. That because it wasn't traditional, it wasn't fundamental.

The core mistake with that argument, whether in the context of same sex marriage or marriage among persons already married, or in larger numbers than two, is that what's fundamental is not opposite sex marriage, or same sex marriage, or polygamous marriage, but simply marriage, without qualification of any kind.

Yes and no... Opposite sex or same sex marriage is the same institution, marriage, and nothing changes when you change the genders of those involved. Polygamous marriage is a different institution, as you admit when you said "the question of marital property [in polygamy] is one of the issues that legislatures will have to address when the ban is overturned as it inevitably will be".

As a different institution, the fact that marriage is a fundamental right is irrelevant to whether polygamy is a fundamental right, any more than a right to marry being fundamental means that driving a car is a fundamental right.

But, if you change, "spouse and spouse" to "a group of spouses", then how do you change "upon death of a spouse, the remaining spouse shall inherit 100% of communal property before probate"? As in, you die, and your three widows each inherit 100%? That's 300%. Where do you get two more identical houses?

Well, first, the spouse is generally only entitled to 1/3 of the assets and in some cases, up to a certain dollar amount in an intestate death. Wills and contracts normally supersede all that unless the widow(er) receives less than that amount in which they can contest the will (though usually not the contract).

But to answer the question, it would be the unit "spouse" that receives the inheritance. If there was three spouses, they would all have to act as one unit for the transfer then figure out what to do after that. It's no different than a company being owned by 20 people that dissolves or is somehow transferred. In fact, I have two minor stakes in partnerships that one says upon my death the companies will be sold and 30% of the value will go to the first heir in the estate of the deceased and the other says my stake is to be transferred upon death to the partners. Both of those will happen before any inheritance or probate takes place.

That is a fine and workable solution but it can't be done by simply changing the word "wife" or "husband" to "spouse". It would require a new statute that is similar to the above (or likewise based on the Uniform Partnership Act, which covers your other situation). That's different from simply enabling gay marriage..

I interpret this differently.

AMD cpu division has been losing money hands over fists since the first i series for quite some time. It doesn't matter if it fits your needs. It only matters if they can compete with Intel. They can't.

ATI however brings in some money I guess. So this is a test to see if the intel version sells 4x more. If it does perhaps it is time for AMD to leave Intel to the x86 to remain solvent? It pains me to type this as I went AMD since the athlonXP days to the phenom II I just retired last summer.

Sorry Hairy but in Star Wars the OLD republic where I got 20 FPS I now get 40 fps iwth the same video card since I went from a 2.6 ghz 6 core phenom II to a 3.5 ghz i7 which is only 4 core. If I wasn't so cheap ... or I should say ex would allow me to spend $150 for a 2010 i5 when I bought my phenom I would not have had this problem.

Also AMD really does suck with power management. You won't see my MS Surface carrying an AMD anytime soon. My coworker like you is an AMD fanboy but he admits for a notebook he won't touch AMD.

As tablets take over as the Surface and WIndows 10 with universal metro apps and 2 SDK's to port IOS and Android apps with 85% of the original code to IWndows Phone/Windows 10 take off in the coming years this will be ever so important. True WIndows 8.1 was frustrating and both of us hated it with a passion, but I concede it rocks on a surface and Windows 10 is what 8 should have been.

So I could be wrong but a test to dip the waters is my 1st guess. Second AMD could be preparing to leave the cpu market entirely since Intel is about to embark .14 nm skylake. What is AMD .28??? Slower performance, more heat, and more power sadly since they sold of global foundaries. Global foundaries are reserving .14 nm chips for phones. AMD is too small of a market to give a crap about. Ouch ...

That is a poor way to do this.

No apps SHOULD NOT write to the registry ever with the exception of an installation. Yes ask a DBA about forks or run Firefox for extended periods of time whose profile on SQLite will slow its startup over time :-)

Also what about security? Do you really want any app writting to it? If your browser writes to it and have a crafty Russian Flash app then through a bypass a website can do whatever it wants via your registry. This is a no no from that perspective as well.

Infact Windows 7 has virtualized registry changes to not corrupt the real copy. When an app you install fails it will ask you if it installed properly? This is to undo the changes.

The proper way is to have a service that runs as admin but even that should not write to the registry all the time and UAC prevents this which is what pissed people off about Vista. Microsoft's plan was to get the users mad at the vendors for writting shitty annoying apps. Not MS for it's OS. But Vista forced poorly written apps to be rewritten for Windows7 which will not impact the system.

I disagree.

Windows 7 is still very snappy on my AMD phenom II. XP had WIndows ROT problems with poorly written apps and even updates which forked the registry many times which impaled the startup process. I have not seen a slowdown at all. I do admit I upgraded to an i7 and now have 8.1 on it but I occasionally use the other system.

I think he has .net framework recompiles going which happen after these updates are one of those defective evo 840 drives which will halt after a few months without a patch to fix the charge leakage bug.

1. Your operating system is very old at nearly 7 years. Time flies bye and I laugh at the companies who are angry at the prospect of starting a WIndows 10 migration acting somehow that 7 just came out last year and is all so new etc. The point is you will have 200 updates and the .net framework will need to re-compile to your cpu dependent architecture each time an update hits for better performance. Have fun with that one.

2,
Windows ROT is soo last decade with WindowsXP.

It is caused by poorly written programs that run as admin and write to the registry each time they run. So you run the app 200 days a year and it creates 200 forks of the registry that need to launch in parallel at startup :-)

With UAC WIndows 7 doesn't have this problem.

3. Do you own an Samsung EVO SSD?

If so they will slow to a crawl very rapidly without a patch. They will hang after a few months of heavy use for several seconds before a file even transfers. I only buy the pro drives. Go google this up as their is an engineering flaw which impacts the read due to the way the cells are manufactured.?

According to the court's majority decision marriage is not about property and inheritance rights, but about love, spirituality, etc.

From the opinion:

Indeed, while the States are in general free to vary the benefits they confer on all married couples, they have throughout our history made marriage the basis for an expanding list of governmental rights, benefits, and responsibilities. These aspects of marital status include: taxation; inheritance and property rights; rules of intestate succession; spousal privilege in the law of evidence; hospital access; medical decisionmaking authority; adoption rights; the rights and benefits of survivors; birth and death certificates; professional ethics rules; campaign finance restrictions; workers’ compensation benefits; health insurance; and child custody, support, and visitation rules. See Brief for United States as Amicus Curiae 6–9; Brief for American Bar Association as Amicus Curiae 8–29. Valid marriage under state law is also a significant status for over a thousand provisions of federal law. See Windsor, 570 U. S., at ___ – ___ (slip op., at 15–16). The States have contributed to the fundamental character of the marriage right by placing that institution at the center of so many facets of the legal and social order.
