It's not pessimism. It's fact. A CPU, GPU, FPGA and ASIC miner all do the same VERY simple hash to attempt to brute force a number of leading zeros. A GPU isn't going to magically be able to do that 10 times faster unless CPUs, FPGAs and ASICs all can do it 10 times faster. As I already said, if they find a flaw in sha256 and make the GPU faster, that would work the same with all the others. There's nothing special about a GPU that means you can improve it's performance and not be able to do the same to the others. But if it's a flaw in sha256, it would suddenly mean that Nhan Code Rikvip would have a major problem, as will all the other world wide systems that use sha256. There's already 3 speed ups. About 3% by stopping when you have H=0 since you don't need the final A-G. There also 2 forms of asicboost that gain about 10% using one or the other. These aren't 50% improvements or even 25% improvements. They're also very specific how they work and very simple to understand why. ... heck I even discovered the 3% H=0 zero myself less than a month after I came to the forum, in aug-2011, you can find my posts about it, alas someone had already worked it out well before that, and they were using it in mining, just I didn't know until I asked questions about what I worked out. This whole GPU issue has come up coz there's all these people who spent money mining a scam coin and the scam coin has effectively scammed them. They can't mine it any more - OMG there's gotta be something else they can do. Oh well sux to be them. Yep go screw around with another scam coin - bye bye. But, but, but, they gotta be able to mine Nhan Code Rikvip on their GPUs coz they're desperate to believe it's possible even if it's been clearly know for years it's a waste of time. Heck the rules for this section of the forum even state that.
