Hmm, let see. People complained from Nvidia's bad business practice, being unethical to no moral. Some even jump on Keys about being a member of the Nvidia's focus group. What do those have to do with How Nvidia helps keep PC gaming alive?
Does anyone mentioned anything about AMD's contribution on gaming consoles? To PC gaming? If you can bring one or two on the table than you may be able to disprove what the title states.
People continuously claiming that Nvidia take away what AMD user should have, but it really isn't difficult to see that without Nvidia, there won't be PhysX, batman's AA, and CUDA. Without AMD on the other hand, everyone will be able to enjoy all those. Who is the blocker here?
Do not be fooled as AMD can purchase PhysX from Nvidia, yet they decided not to. And you can mark my words, if AMD can proprietarize something, they will. It is dump not to. In reality, people don't say thank you after taken your stuff. Consider yourself lucky not getting seriously hurted during the cause. In business, no one pitty you, but laugh at you or take advantage off you. If your work is worth 1000 bucks, people will ask to sell it for a dollar. If you don't protect yourself, then you don't worth a dime. Welcome to the real world.
All companies are aiming for the cash in your wallet and bank. You, regardless of you like it or not, will have to pay some of them. Nvidia ask for you to pay, in return give you a piece of metal and spend a bit from what you pay on helping game developers somewhat. At the end they take a big credit as if all games will cease to exist without them. However, why will you buy a console port if it looks exactly the same as with your 4xfire 5970 or 3xsli 480 compare to a 300 dollar console? Is it the 200+FPS that is running on your 23" 60hz monitor? Yes PhysX, specifically when it is running on GPU, is simply a few more pieces of paper, leaves, sparks or whatever of those shape flying around. That however, it is a good enough reason to a purchase of the PC version of the game. Could game developers made it without Nvidia's little dirty, backstabbing, unethical, no moral tricks? Yes. Would they? probably no. Why? Well other than a bit better FPS and PhysX, there are no other differences. Rule of thumb, biggest sales with the least amount of work. Adding extra on something that can only be ran on PC defeat that premise, and therefore unless it is a PC only game, it rarely happens.
In the business world, companies eat other companies. Cheating is the usual, and if you don't get caught, you win and no one will question. Laws are like a fence and tricks are like water through the fence. Unless you are really dump or go way overboard, it isn't there (Tax however, can't be avoided.) Hoping laws will protect you is worst then winning lotteries. If you don't know how to protect yourself and what belongs to you, it will be gone in no time. Only your debt follows you. Proprietarizing softwares that you made is not wrong, it is right because if you don't, someone else will proprietarize it away from you.
I typed too much.
