High res

I went back to the default options in compute settings, I unchecked the "use full precision for model" box, set the precision back to Autocast, except now I checked the "use full precision for vae" box. It's almost twice as fast to generate and uses way less vram.

I wish I did this earlier, the only reason I didn't was because it was giving me empty black images but the fix was using full precision just for the vae and not necessarily for the model. 

And the reason I found out was because today I had to do a fresh install after having some other issues... T_T

I can probably go even higher res since it's so fast now.
