Is there a recommended specification of PC to show Celestia graphics at 1920 x 1080P 50hz resolution,ie graphics card, ram etc.
Re: High Definition
Celestia's performance depends on how much you ask it to display.
If you have lots of addons visible on the screen, it'll run more slowly.
The biggest, fastest system you can buy may be too slow if Celestia has to draw many overlapping models, for example. Celestia currently is single-threaded, so having multiple cores does not help Celestia itself, but does improve response for whatever else is running on the computer. My understanding is that Intel's Core i7 processors will actually increase the clock speed of one of the cores and shut down the others when it detects that a CPU-bound single-threaded job (like Celestia) is running.
A faster disk improves load times for large Addons.
Lots of memory allows more and larger Addons to be in memory simultaneously.
(However, Celestia is a 32bit application, so it can't use more than 4GB.)
A faster CPU improves the speed of orbit calculations and detection of objects within the viewpoint window.
A faster GPU improves the speed at which models and antialiasing are drawn.
More memory in the GPU increases the performance when many Addons are visible.
