Did you load the full catalog? I dont think its worth it if they dont know the stellar spectral types
I just installed the 3 million star addon and if I set the magnitude limit too high my PC just dies (0-3FPS) and then I get a cascade of a dozen c++ run time errors come up shortly after. I can barely reach the visibility of them that's shown in the video without a complete meltdown of my CPU.
My CPU is just too slow to load that many stars. All 8 cores are at 100% when I view the Gaia stars lol. Need moar powa!
