CUDA, Phys-X are doomed: Roy Taylor

[pam]

Sometime back in 2010, Nvidia clearly stated they "wont" support wayland. Can be passed off today as irrelevant poppycock.

AMD's Roy Taylor now states CUDA and physX is doomed. I mean its like everyone is defending Nvidia, including me, but its the truth based on reality. How many software companies care for physX. Hair simulation, cloth simulation as a sole purpose?

CUDA is available and not an option for GPGPU compute. Granted Blender has pulled out support for OpenCL, but its to improve and sift out anomalies to make it a full force technology when it gets implemented. Whatever OpenCL apps exist excel only on radeons, not that its of relevance, bitcoining uses it. Even intel graphics are shockingly more powerful than a previous generation when it comes to OpenCL/GL.

CUDA is closed source. OpenCL is open source. That says it all. Furthermore ARM based embedded chips depend on OpenCL/GL compute.

I have played games like Assassin Creed III and Call of Duty Black Ops II with and without Phys-X. Phys-X looks SOOOOO much BETTER. MORE REALISTIC. It is unfortunate that many software companies are not looking into the technology more.

Even Star Wars: The Old Republic looks much better with Phys-X enabled.

The PC version Assassin's Creed III takes advantage of specific PC technologies to enhance the overall gameplay experience. TXAA is leveraged throughout the entirety of the game, and DX11 Tessellation is used in the winter season of gameplay.

TXAA is a new film-style AA technique designed specifically to reduce temporal aliasing (crawling and flickering in motion). In this video look at the buildings, the ropes on the ships, and the foliage. Without TXAA, you can see crawling, most vividly while the character is in motion. When TXAA on, the crawling and flickering practically disappear.

In Assassin's Creed III, tessellation is used to smooth out the footprints left in snow by the player in heavy weather situations. Tessellation dynamically produces more polygons in a scene to create a more realistic rendering compared to standard methods. You will experience a lot of snow during the game and this technology enhances the realism and fidelity of your experience.

For a limited time, purchase any qualifying GeForce GTX 600-series graphics card and get Assassin's Creed III FREE*! For details, go to http://www.GeForce.com/FREEAssassinsCreedIII

Thanks ryanvade, for the videos.
I can see that phys-x does provide cool effects. I have already used in borderlands-2.
You do realize why more software companies dont care much for someone else's technology. They dont want to be restrained and then get sued by license issues. Engineers and programmers dont care for license issues, that's why people like Stallman and Eric Raymond exist.

Almost all game companies use their own physics and engines; cryengine3, id-tech 5, Havok, OpenGL, 4A etc...
Cevat Yerli said cryengine 3 will incinerate your graphics card. And it does to the word. There are practically no graphics card today that can run cryengine 3. A GTX 690 is SLI does not qualify when 24 months from now a mid-end card will run it with full MXAA and beyond at 60fps on a higher resolution beyond 1080p. 4K displays are selling locally in all countries and they cost half of what a plasma TV came out when it did.

An argument arrives why would an engine like cryengine 3 care for phys-x when it is years ahead. Phys-x is a feature in GPU's just like AVX is a feature in CPU's. When you close source it--- Imagine? I know its just another feature but when devs have easy access to it the word 'limits' does not fit in. ARM based CPU's use more instruction sets than desktop ones. It means they do not depend on clock cycles for processing data and if they did everybody would carry a spare battery. As an example you dont need a 1 Ghz processor for churning data for listening to an mp3 file when its already being encoded by the hardware.

I also know companies and people take advantage when the time is right and attack each other. To add to the abuses AMD does not monopolize, its just that its easier to work with them. PS4 wont have DRM crap. You can copy the game or resell it or give it to anyone who uses a PS4. There are no hardware-software restrictions. The goal is quality games and easy porting to PC.

But why AMD users are open to Nvidia. Everything Nvidia does is behind close doors. What if they opensourced Phys-x? What if OpenGL could be linked to phys-x? What if web browsers could use phys-x and CUDA, without caring much? If they really open-sourced CUDA, the argument AMD vs Nvidia would cease to exist. Price was never the problem. Look at Intel. They are selling products at ridiculous rates. But the open source support by them totally invalidates that. People defend intel, that their products perform better and are made for the enthusiast market but the truth is their technology revolves around open-source. They do provide a ton of support for their CPU's and GPU's.

Thanks Again!!
WHat can i say, im dumb and stupid.

No, your not. The developers that spread rumors and don't look into technology that will make their programs better are.

Checked and rechecked.
PhysX is 100% proprietary software. Only SDK(software dev kit) is free to use and exploit. The physics engine itself is proprietary.

Yes it is, but for small time developers its use is free. Bellow a certain amount of income.....

Nothing wrong with proprietary. If needed it is possible to get the source code, but you have to pay. I use Nvidia drivers which are proprietary. Even Richard Stallman has no issues with Proprietary.

You are right, there is nothing wrong with proprietary.

My point being, adoption of technology has its limits. Open sourcing it provides endless possibilities. Doom 3 is made open source by Carmack but still its a long way off before devs can cannibalize the code and use it in practical ways for linux etc. The day of the script-kiddie is over. Coding is hard work. Nvidia does not provide linux support for geforce-- it means nothing. They Have to close source it. And their drivers have stood rigid for long. PhysX is a solution to a problem that never existed. If i am a game dev would i use physX? From job point of view it makes sense. Game engines today dont depend on hardware, they are scalable means even a first gen GDDR6 card would only leverage the performance of Cryengine3.
