I am sure many would welcome such development, but I had an SLI system once and it created more issues than it brought me any noticeable gain so I abandoned that concept again.
I would want to see it tried out with a whole range of games, learn more about the micro-stuttering issue and how it affects the user in VR (which would seem to make it even worse than in flatscreen gaming) etc..
Not trying to be negative, but I am certainly cautious. It would be cool if you could continue to report the performance with other games, and perhaps feed that with measured FPS and settings comparisons so we can quantify the advantage it offers a bit more. Is it 20 or 30 % more than with a single card, or does it do some magic and achieve a higher value proposition ?
