Both of those have much higher regulatory costs than their subsidies, though my understanding is that coal is a better proposition that way.
  Which is sad because nuclear with modern designs is far better than solar or coal. Coal actually puts more radiation in the environment and solar produces a lot more toxic waste compared to many designs that effectively recycle their nuclear waste down to a tiny fraction of older designs.

It was sooner than twenty years ago, probably close to 8-10 IIRC. I looked into it because my dad asked me to as he was thinking about putting solar on his roof. At the time they were still not (as a practical matter based on the real world, not a panels theoretical output under ideal conditions) not there. Theoretically in ideal conditions they were close, something like 95% if you used sun tracking near the equator with defect free cells that never degraded faster than expected and never had any cloud cover.
We found he could spend about 6500 to save about 7800 over 10 years if he got all the tax breaks and bought the cheapest reputable brand he could and did all the installation himself. Or he could put in a 4 hours overtime a week for 3 months and make more.
The horrible toxic wastes that making the cells generate were just salt on the wound for him.

Actually they cost more than that. But many governments subsidize their production and/or purchase by the end user.
    If they really have gotten significantly cheaper (actual costs, not post subsidy) than they produce over their lifetime in the last few years I've missed it (not really looked into it in abt 5 years).

It'll be a while, it currently take more energy to make a solar panel than it can generate in it's lifespan and costs more than coal or nuclear without the subsidies.
And that's not even counting that solar panel production has so much toxic waste associated that it's one of the worst.
That said I do like the potential if we ever find a way to make solar cleaner and cost effective without government (tax payers) money artificially sustaining what would otherwise be an economic failure.

It can, only problem is last time I checked (a few years ago though) it took about 6 TW of energy to produce solar cells that could deliver that much energy. It also produced more and more highly toxic waste than the same in coal which in turn produces more radioactive contamination than nuclear, which in modern designs is even better and much safer.

There are plenty of clever things that can be done to mitigate the resolution issue. One of course is higher resolution. I recall a 3d simulator at an arcade decades ago that did just fine with much lower resolution.
      For example look up some of the fake 120hz schemes in use (I think true motion 120 is one of them).
Another is of course the quality of the display units themselves, as well as any associated optics.
4k and 8k (esp. per eye!) would be great. But I think we're a bit off from single card solutions to drive that in 3d games. 4way sli/crossfire with the latest dual gpu cards and lots of fast ram could probably do it though.
