You must be very young, or incredibly stupid, and likely a liberal blending of the two...
Slight bit of difference in the Video Games industry and BTC here, tiger:
One is a speculators bubble with close to zero real world adoption, and the other is A MULTI-FUCKING-BILLION DOLLAR INDUSTRY THAT'S THIRTY YEARS OLD.
First off, please take a deep breath, close your eyes, and calm down. This is a simple discussion on a forum, no reason to get all worked up calling people stupid and screaming in all caps. If you just want to flame away without any logical argument you can have your "win", I won't bother to respond further.
That said, you made a false comparison. I was comparing spending some time to optimize for BTC mining to optimizing one single game. Not an entire industry, one game. Nvidia puts out money and time to work with a developer of a single game just to make sure it runs better on their hardware.
Complaining that BTC mining might just collapse with the speculative bubble is itself silly, because while that may happen, it's 100% certain that a given video game's sales and popularity will spike and collapse, it's the nature of the market. Obviously nvidia is willing to expend money to optimize a game that might be popular for 2-3 months before fading into obscurity, so I don't think it's too far fetched to say they could consider doing the same for bitcoin mining.
Worse case, mining sputters out into obscurity in a few months, exactly like the average big budget new release video game. Best case, it might remain popular for a few more years, or forever. But as long as the worst case scenario for BTC mining is equal to current PC gaming projects that nvidia invests in, I don't see how your argument holds any water.
For example, here is a list of SLI optimized games. SLI itself is a niche product, probably less than 5% of PC games run SLI, yet nvidia is putting time and effort into making these games work, some of which were huge duds.
